Nitrogen is essential to life and is among the nutrients consumed in the largest quantities by all agricultural crops. However, today’s linear flow of nutrients (nitrogen, phosphorus and potassium), from fertilizer manufacturing to wastewater treatment plant (WWTP) via food production and human consumption, is not sustainable.
The demand on nitrogen removal at WWTPs is increasing and nitrogen-containing effluents overall should be viewed as a nitrogen resource. Water streams with high ammonium content, such as reject from sludge dewatering or landfill leachate, are suitable for nitrogen recovery.
EasyMinings new patented innovation enables efficient removal and recovery of ammonium from aqueous flows. The unique solution uses chemical precipitation of ammonium, by adding an adsorption chemical to the waste water. As a second step the captured ammonium is recovered in a conversion plant to a fertilizer and the adsorption chemical is regenerated to be used again.
EasyMining is now working in a project to demonstrate this new, innovative removal and recovery process for ammonium nitrogen which can be used for different ammonium containing liquids and enables production of different ammonium products (e.g. fertilizers). This is an EU project, funded by the LIFE programme.
