Recycling nitrogen from wastewater as a conventionally used product
Ragn-Sells’ innovation company EasyMining has developed a technique that removes and recovers nitrogen from wastewater. The technology is being demonstrated in a project, RE-Fertilize, with financial support from the EU LIFE programme.
Up to now, water with a high nitrogen content, such as wastewater, has mainly been cleaned biological using bacteria that separate nitrogen from water – a process which is both costly and sensitive to disruption.
According to Anna Lundbom, Head of Marketing at EasyMining and project manager for the RE-Fertilize project, the currently used biologically processes just release the nitrogen into the atmosphere after removing it, while EasyMining’s process recycles the removed nitrogen.
- We want to recycle the nitrogen and use it over and over again. What we do is to capture more than 98% of the ammonium nitrogen and then convert it to a form, ammonium sulphate, that today is being used in the fertiliser industry, explains Anna Lundbom.
- As for all circular solutions, it is important to have partners from different parts in the value chain. In the RE-Fertilize, we partner with BIOFOS to secure that our process actually solves the problem for water treatment and with Lantmännen to secure that the product is usable for the agriculture, she continues.
