Boilers and cooling towers are commonly used for industrial purposes. In order to maintain the efficiency of the boilers, from time to time, the water inside the boilers needs to be disposed. This water is commonly known as blowdown water. Due to the characteristic of the water, the discharge of the blowdown water is regulated, especially when the water is disposed to the environment.
Similarly, wastewater is also produced from the operation of cooling towers. Chemicals such as anti-corrosion chemicals and biocides are often added as part of the operation. These chemicals are often found in the wastewater and can be harmful to the environment. Therefore, the disposal of the wastewater is regulated by the relevant authorities. For example, in Western Australia, the disposal of the wastewater produced from cooling towers is controlled by the Water Quality Protection Note (WQPN) #99.
In an ideal condition, the water used in a boiler should be pure water where it does not contain any substances and gases dissolved in the water. The availability of impurities in the water will cause a reduction in efficiency of the equipment and the life expectancy due to corrosion. However, in reality, raw water used for boilers is far from the ideal condition. The raw water often contains hardness, oxygen and other impurities which would result in scale formation and corrosion inside the boilers. To avoid this, chemicals are often added to adjust the characteristics of the water to make it more suitable for the boiler operation.
Although this adjustment is beneficial for the boilers, the accumulated “conditioning” chemicals will now be available in the blowdown water, making it more harmful to the environment. The condition will be worsened in an unoptimised boilers operation, where the “conditioning” chemicals are added in excess.
In the case where there is no access to the sewerage system, these wastewater needs to be disposed with other means, such as environmental disposal. However, to meet the environmental disposal condition, the wastewater will require treatment prior to disposal.
For this situation, most consulting firms approach the problem by looking for options for treating the produced wastewater. Based on EEI’s experience, we understand that in some cases, the most effective method to solve this problem is by avoiding the creation of the problem. Instead of analysing the problem downstream, EEI analyses the problem upstream by analysing the operation of the boilers. Through this analysis, changes to the operation of the boilers can be made which allow a cleaner production of blowdown water, hence requiring minimal to no treatment before environmental disposal.
RMAX Options Assessment for the Disposal of Wastewater Produced from Boilers and Cooling Tower
RMAX operates boilers and cooling towers as part of their manufacturing activities. Due to the unavailability of access to the sewerage network, the wastewater produced from the boilers and cooling towers are required to dispose through other ways. Under the existing wastewater quality, the wastewater must be treated prior to environmental disposal or it needs to be captured and disposed through third-party services. This decision was made based on analysing the constituents of concern available in the wastewater. However, based on the analysis of the constituents of concern, EEI has identified potential improvement to the operation of the boilers. Through the changes, it is predicted that a significant improvement in the wastewater can be achieved, thus allowing safe environmental disposal.
Environmental Engineers International Pty Ltd (EEI) has been recognised at the Australian Water Association (AWA) WA Water Awards for the second consecutive year. The company was proud to receive the 2017 Research Innovation Award, and the Water Professional of the Year Award for CEO Dr Raj Kurup. The awards are testament to the excellent year that EEI has had, fostering innovation and technical excellence across a range of projects in the water industry.
EEI received the 2017 Australian Water Association (WA) Research Innovation Award for the development and implementation of its ANRUP Anammox Process for nitrogen removal for an abattoir wastewater treatment plant . The objective of this project was to understand the process, requirements, and the difficulties in implementing anammox in an existing wastewater treatment plant (WWTP). The anammox process is an exciting state of the art technology for nitrogen removal.
The project has verified that the anammox process offers significant environmental and economic benefits. The reduced aeration requirements, and elimination of carbon dosing offer WWTPs a clear pathway to cut operating and capital costs. Overall it has been determined that the payback period for the implementation of the anammox system has been less than 18 months, and included a suite of operation and maintenance benefits. The project also has demonstrated that a pure anammox culture was not required for start-up, and the technology is eminently scalable and applicable to both new and existing plants.
The prestigious WA Water Professional of the Year for theaward for Dr Raj Kurup has been 25 years in the making. Raj has made tremendous contributions within the water sector as an engineer and researcher. He has authored over 60 publications, and delivered key note addresses for several international conferences. Raj's research has led to the development of EEI's innovative technology, including the High Rate Anaerobic Reactor (HART), ANRUPAnammox process, Self-Regulating Suspended Biogas Collectors (SSBC), and phosphorus removal products.
Another key criterion for the judgement of the Water Professional of the Year Award was the nominee's voluntary contribution to the water industry, particularly the development of future water professionals. The engineering internship program at EEI has been one of Raj's proudest achievements, and it has given him great satisfaction to mentor the WA water engineers of the future. Upon receiving the award, Raj wanted to relay his thanks to his family, excellent clients, and mentors that have been such a large part of his career journey.
Peter Rice accepted the WA Water Professional of the Year Award on behalf of Dr Raj Kurup as Raj was away overseas then. You can click the link below to listen to Peter's speech at the award ceremony.
The Institution of Engineers Australia (EA) has selected Dr Raj Kurup, CEO of EEI as Australia's Most Innovative Engineer in Consulting for 2017 for the development and implementation of the Anammox process for nitrogen removal from wastewater.

Environmental Engineers International (EEI) is pleased to announce that Dr Raj Kurup will be the presenter for a special upcoming event hosted by Sustainable Engineering Society WA. Raj will be speaking about the successful retrofit of the EEI-Anammox process for Dardanup Butchering Company's (DBC) Wastewater Treatment Plant (WWTP). The seminar will be held on Wednesday the 20th of June at the Engineers Australia WA Auditorium. Registration is available to anyone, and EA members and students can attend for free. More information can be found at:
Since the implementation of the EEI-Anammox process two years ago, the DBC WWTP has consistently achieved excellent nitrogen removal, without any extra carbon addition. The plant is monitored online for various parameters to ensure its effective operation. The WWTP has achieved over 20% savings in overall electrical power since the implementation of the anammox process. Unlike the European case studies, the DBC WWTP has achieved over 95% TN reduction even during the winter months when the temperature has fallen below 15o degrees Celsius.
Dr Raj Kurup is an internationally reputed and award-winning environmental engineer and project manager with over 25 years of professional experience in various facets of environmental monitoring, water and wastewater treatment engineering, sludge management, odour control and management and nutrient removal technologies. Raj has a long history of providing innovative solutions to challenging problems that are economical, environmentally and socially informed, technically advanced and operationally simple. He was awarded the title of Australia's Most Innovative Engineer in the Consulting Category from Engineers Australia in 2017 for his work in developing EEI's anammox technology, and the WA Water Professional of the Year (2017) from the Australian Water Association.
EEI hope you can attend this exciting event.
EEI's strength in research innovation has been recognised for a second consecutive year at the WA Australian Water Association (AWA) Water Awards Dinner 2018. The Self-Regulating Suspended Biogas Collector (SSBC) Technology developed by EEI won the coveted Research Innovation Award. While EEI's field study of sensor technology for wastewater treatment plants was also an awarded finalist in the Sustainable Water and Environmental Outcomes category.
The SSBC is a new approach to gas capture for reactors and lagoons. The global biogas industry market is expected to grow to $48.8 billion by 2026, and there are significant economic and social benefits for Australian industry and the community resulting from the development of the SSBC technology.
EEI have always been passionate about implementing anaerobic technology where conditions are appropriate. It is the most energy and cost-effective treatment pathway for high organic wastewater streams. When engaging with local industry however, there is typically an inherent trepidation surrounding biogas collection and the anaerobic pathway.
The conventional biogas capturing technologies have a number of problems such as limited access to the internal of the reactors, risk of damage to the cover that can cause complete loss of methane produced, and difficulty in retrofitting to open reactors.
The SSBC can capture and retain produced biogas while floating on top of anaerobic lagoons or reactors. The system consists of a number of small floating biogas capturing modules that operate independently. The system also integrates live weighting to stabilise the modules from capsizing or to control internal pressure.
SSBC's modular design negates the need to shut down the entire anaerobic system for maintenance. Desludging and crust removal operations of the anaerobic system itself have been shown to be much more accessible in contrast to the current technologies. The patented SSBC technology presents an opportunity for business to implement biogas energy generation with reduced maintenance costs and better production efficiency using a flexible system that can be retrofitted to current reactors or irregularly shaped lagoons.
The community also benefit through the improved environmental outcomes associated with increased renewable energy use to combat climate change, and odour prevention through improved opportunity to capture harmful gas emissions.
EEI wish to congratulate our fellow award winners and finalists and are keen to showcase continued innovation in 2019 and beyond.
EEI were proud to represent WA innovation at the 2019 Australian National Water Awards held at the Ozwater'19 Gala Dinner on Wednesday the 8th of May 2019 in Melbourne. The SSBC was a finalist in the Research Innovation Award category.
Conventional biogas capturing technologies have a number of problems such as limited access to the internal of the reactors, risk of damage to the cover that can cause complete loss of methane produced, and difficulty in retrofitting to open reactors.
EEI would like to congratulate all of the National award winners and finalists, and we look forward to working towards further innovation in 2019 and beyond.

The SPORE Solution
For the fourth consecutive year, EEI is recognised for its innovative engineering solutions. Environmental Engineers International CEO Dr Raj Kurup was selected as one of the most innovative engineers in 2019 by Engineers Australia for the development of EEI’s SPORE sodium oxalate waste (SOW) removal process in alumina production.
The SPORE technology provides the most efficient and economical way of tackling the sodium oxalate waste problem, with an estimated additional net revenue of $4 million of by-product from a singular SOW lagoon with potential operational savings of $20 million a year.
The Australian economy thrives off a growing mining industry, in which alumina production through refining bauxite plays a major role. Australia is the largest producer of bauxite in the world, with 80.4 million tonnes produced in 2013/2014. EEI’s new technologies offer a more effective and economical waste management system for a key challenge in alumina refinery, sodium oxalate waste.
The process of refining bauxite to produce alumina will generate SOW, conventional methods of dealing with SOW involve storing it in lagoons with the excess undergoing thermal or aerobic treatments which have high operating costs. The SPORE solution (Smart Priming Oxalate Removal Enabler) offers anaerobic treatment of sodium oxalate waste lagoons in which it also produces valuable by-products such as methane and sodium bi-carbonate without on-going addition of pH neutralisation chemicals.
Once the SPORE process has been implemented on a storage lagoon it negates the need for building additional treatment facilities or infrastructure. This ensures a safer processing environment due to reduced risk of exposure to highly hazardous chemicals on site.
For further information on the SPORE process please contact us through the contact form.

“What really drew me to it was [that] I knew that the things I studied in University were going to be applied in this specific role, which is what I wanted.” -Ted, 5th year mechanical engineering and finance student
“It was a wastewater engineering consulting company; I’m very interested in water engineering, so I decided to take this opportunity.” -Calvin, 4th year civil engineering student
“What drew me to the position was that I would be able to participate in meetings with clients and practical stuff like project management.” -Thanh, graduate chemical engineer
“For the first few months… I was given a project [to select a pump]. I had to learn about all of this because I didn’t really learn pump selection in University. I knew the general theory about [my project], how the environment affects materials, what flow rate means… I knew that, but I did have to do a bit of study on how to apply that to pump selection. But after that I was able to contact suppliers and seek specific pumps that would cater towards the project details.”-Ted
“During my three-month placement I worked on the master plan project … I worked on a wastewater treatment plant design, and also worked on the water balance for an evaporation pond design as well.
I worked with my supervisor on the master plan… and it was quite challenging, but he guided me through the master plan and I gained a lot of skills, such as efficient research, and also to judge and make engineering assumptions.” -Calvin
“It was quite different from my previous experiences. For example, we had contact with the CEO, so if we had any questions or we were struggling with the project, we could just go to Raj’s office for help.” -Calvin
“The best part of this placement was modelling the water balance. I had a great opportunity; I did everything in Excel, and once I had finished the water balance modelling, I designed an evaporation pond for the project. It was a good experience for me; I learned a lot of good things from the project.” -Calvin
“[I remember] Thanh worked on the Anammox project, and he needed some help with sourcing materials and designing the setup of the experiment. The best part [of the internship] was working with him to design the setup of the experiment. It was like we were both learning at the same time.” -Ted
“I would not have done anything differently because I would not have learnt what I know now. I wouldn’t change anything; I gained a lot of experience from working here.” -Calvin
“I would come into the internship with a more positive attitude. There were times where I would be given work, and I would think, “I don’t want to do this!” … So if I did have to do it again, I would say, don’t expect to do what you want to do; just expect to learn with the work they give you.” -Ted
“I had the pleasure of working with Peter Rice, who helped me with the water balance modelling. And Nathan, he was a great mentor for me; he guided me, and we worked together most of the time for the master plan.” -Calvin
“I think [Peter] was one of the best mentors I have ever met. He knows what it’s like for an intern to struggle, to get frustrated, so he always encouraged me to keep moving forward.” -Thanh
“I learned from Raj, even if university takes you four years… the learning doesn’t stop there… you’re always constantly learning. If you stop learning, you start becoming useless. It’s a constant form of education, and you have to better yourself as well, to remain competitive in the job market.” -Ted
“Come into the internship with a very open mind… I would say don’t expect anything so you won’t be frustrated in the work they give you. Because with the work they do give you, you will learn no matter what. Just keep in mind, with every problem something different has to be learned. And that might not be something you want to do at the moment, but at the end of your career every little bit helps.” -Ted
“I think the best advice I could give is don’t get frustrated easily, keep pushing forward. Sometimes the project might be delayed, sometimes people might not have time for you. So take initiative, be patient, and believe in yourself.” -Thanh
From the team here at EEI, we want to thank our interns for all of their hard work over the summer vacation period and wish them all the best in their future endeavours.
Every year EEI’s vacation program gives university students and graduates the opportunity to gain experience with hands on projects to equip them for future success. We are currently advertising for expressions of interest in the internship program.

Our most recent batch of interns have completed their time with us at EEI and have provided us with some insights into our winter internship program.
“I am extremely grateful for the opportunity to have been part of the team and to have gained valuable experience during my time with your organisation. During my internship, I had the chance to work on various projects and tasks that allowed me to apply the knowledge I gained during my studies. The constructive feedback and regular check-ins from Raj and Peter helped me grow both personally and professionally. I feel more confident in my abilities and have a clearer vision of my career path going forward.
Moreover, the internship program's structure and the opportunities for networking and professional development were well organized and beneficial. The presentation sessions and interactions with employees from different departments broadened my horizons and enriched my overall experience.
It has been an unforgettable journey, and I genuinely believe this internship has set a solid foundation for my future career. I would be delighted to stay in touch with the team and potentially collaborate again in the future.”
"I thought it was a very educational experience particularly in how to work in a professional environment, which I hadn't done before. I learnt skills in report writing and had experience in working with other industry experts such as chemical engineers and environmental scientists, not just chemists (like me) which was very broadening to me and made me realise there are interconnections within different disciplines. I found the presentation useful in increasing my skills in presenting to others and have identified my weaknesses that I need to work on in future."
“I would like to start off by saying thank you for this opportunity to be able to complete and participate in this internship program. I enjoyed learning how an engineering firm operates, and I am grateful to be able to contribute my engineering skills and experience through this program. I am sure I will take this experience and be more confident in my work in any future engineering work I partake in.

We're thrilled to announce our innovative SPORE Process has been granted patent in Vietnam!
This continued achievement validates our innovation and dedication to pushing boundaries in the alumina refinery and waste management industry globally.
The journey started in 2016, when we were approached by an alumina refinery to develop a better solution for management of legacy sodium oxalate waste (SOW) stored in tailing dams.
SOW is a highly alkaline (pH ~13) residue of the Bayer process, and is a common problem faced by alumina refineries globally. The cost of neutralisation has led to long term storage of SOW in lagoons while an acceptable solution is found.
Solving SOW fulfills EEI’s vision and philosophy, “Waste management should extend beyond merely fulfilling regulatory mandates and should be viewed as a prudent economic investment, with a substantial return on expenditure.”
Our four-year journey encompassed intensive research, laboratory studies, and engineering design, culminating in the multi-award-winning technology known as the Smart Priming Oxalate Removal Enabler (SPORE) Process. SPORE enables legacy SOW storage lagoons to be converted into anaerobic reactors that produce valuable by-products, without on-going addition of pH-neutralisation chemicals. This patented technology can save a typical refinery up to $20 million per year in operational costs.
Our approach to the SOW conundrum shows our commitment to innovation. We took a different approach to SOW treatment, given the high costs and operational failings of conventional technology. We combined lessons learnt from other industries, our anaerobic and circular economy experience, and a solid technical foundation to propose the anaerobic pathway for exploration.
SPORE has generated interest from alumina stakeholders worldwide. We have already achieved successful Patent Cooperative Treaty for global patents, and secured patents in individual countries including Australia and most recently Vietnam, fostering technological advancement, innovation and economic growth.
We are grateful to our team for their dedication and look forward to the future possibilities this patent unlocks.
We are very excited to announce that Environmental Engineers International have been shortlisted as a finalist for the REMSMART Innovation Excellence as awarded by the Australian Institute of Management Western Australia (AIM WA) for the Pinnacle Awards.
Congratulations to the team, highlighting the dedication, hard work and expertise towards innovation, and showcasing what can be achieved when we come together.
Our multi-award-wining technology, the Smart Priming Oxalate Removal Enabler (the SPORE Process) encompassed intensive research, laboratory studies, and engineering design, achieved through a 4-year journey and highlighted our efforts towards Innovation Excellence.

We are excited to announce EEI has been successfully granted patent in India for our revolutionary SPORE Process!
India joins the list of countries where our SPORE technology has been awarded patent, with Vietnam and Australia, alongside successful Patent Cooperative Treaty for global patents. This achievement continues to validate our innovation and dedication to pushing boundaries in the alumina refinery and waste management industry globally.
SPORE serves the environment by:
a) Reducing the risk of legacy sodium oxalate waste (SOW) storage lagoon environmental contamination through remediation and creating the opportunity to converting the lagoons as reactors.
b) Providing an alternative to energy intensive treatment processors, reducing greenhouse gas output. Additionally, methane generated in the process is captured for beneficial use – turning the treatment facility carbon neutral in operation.
c) Creating product streams of sodium carbonate and aluminium hydrates that would otherwise be wasted. Recovering these products reduces the demand for new materials.
d) Reducing freshwater usage at the refinery to maintain storage lagoons/tailing dams.
e) Providing a new opportunity to remediate legacy tailings dams with toxic reagents from other industries such as coal, copper, gold, lead, zinc, iron, and silver.
EEI regularly employs our engineering skillsets to treat highly contaminated industrial waste streams. Given the recent tragedies with tailings dams, we have recognised the risk SOW storage poses to the environment and community.
Release of SOW to the environment through an accident or critical event would cause significant damage. The SOW has a pH of 13 which is incompatible with most life. Eliminating the need for large volumes of SOW storage is the best way to manage the risk. SPORE presents the mechanism to decommission SOW lagoons because of the economic and reliability benefits.
SPORE technology also offers:
• cost-effective treatment of sodium oxalate waste.
• revenue generation from treatment by-products approximately $150/ton of oxalate.
• protection against groundwater contamination.
• reclamation of storage dam land.
The community stands to benefit as SPORE addresses the oxalate issue, safeguarding the environment while fostering industrial prosperity.
Employing SPORE to resolve the legacy SOW issue is not the only potential application. EEI continue to develop new applications for SPORE beyond oxalate treatment. Several mining waste management challenges are potential candidates for SPORE including coal tailings waste rehabilitation and energy recovery, remediation of acid mine drainage, cyanide destruction in gold tailings, and bioleaching. This versatility exemplifies the adaptability of the technology to various waste management practices across Australia and overseas, expanding our business network across diverse markets.
This innovation provides opportunity for alumina refineries to attain social licence to operate. SPORE enhances sustainability by reducing greenhouse emissions and the demands of virgin hazardous chemicals and facilitating reuse of freed assets for the refineries. This is a win-win for the industry and the community.
We are grateful to our team for their hardwork and look forward to the future opportunities this patent holds.
