SolarSpring Newsletter: Reducing CO2 emissions and recovering resources at wastewater treatment plants with smart membrane technology

SolarSpring, a 100% Clean Industry Solutions subsidiary, has developed a process capable of severely reducing CO2 emissions from municipal wastewater treatment plants by extracting ammonia from the digested waste. Not only is the ammonia removed from the wastewater, but it also used to generate a highly nutritious fertilizer which can be distributed on farmland. Wastewater treatment plants benefit from a reduction in necessary aeration technology, an energy consuming component of the plant, plus have the opportunity of reducing their carbon footprint.


After a rigorous testing and piloting phase under real life conditions, the process which is based on membrane technology is now ready for the next level- large scale implementation. The effective concept of the technology has already caught wide attention amongst wastewater treatment plant operators, not least since most of the necessary energy required to power the process can be supplied by low grade waste heat, a resource readily available at most of such facilities.


Ammonia is a chemical that can be used in many sectors. Not only as a key component in fertilizer, feedstock, and chemical production but also as a high potential future fuel in energy production. SolarSpring’s ammonia removal technology shows that through innovation and smart engineering new paths towards a circular economy are opening in all fields of the industry and waste management. SolarSpring is committed to being a part of that change, every step of the way.
