Innovations in water technology are vital to finding solutions to the challenges we face today: climate change, ageing infrastructure, urbanization, resource shortages, the economic and financial crisis, new emerging substances, the need for sustainable development and demographic changes. Our experienced Research and Development technologists are continuously working on the development of game-changing solutions for purifying water and recovering valuable resources.
Here are some exciting examples:
Nijhuis Ammonia Recovery
Several technologies claim effective removal of ammonia from digestate. However, all of these technologies consume a lot of energy and only oxidize the ammonia, without creating a valuable product. By removing ammonia, the treated water can be used for:
- diluting the substrate to enable more co substrates,
- lowering the ammonium concentration of the substrate or
- improving COD/N ratio of the centrate water
The NAR is an innovative and stable process which is anticipating today’s challenges in the market and producing ammonium sulphate, to maximize the value of digestate. The market potential for this biobased fertilizer varies per geographical location, but proves to be commercially very attractive.
