NuReSys’s harvesting technology recovers orthophosphate (PO4-P) and ammonia nitrogen (NH4-N) from your biosolids stream to form pure struvite (NH4MgPO4·6H2O) crystals. The crystals are uniform, typically 1-3 mm in size, and are easily settled in the Crystallizer to be harvested.
For every one kilogram of orthophosphate that is removed, an additional half kilogram of ammonia nitrogen is also removed. Minimum removal of 80% of the orthophosphate present in the solution can be converted to pure struvite, enabling maximum efficiency and recovery within your plant.
This is true up-cycling of your waste stream. Valuable struvite is recovered for re-use as a fertilizer, while the phosphorus and nitrogen loads that are returned to the head of the plant are greatly reduced, allowing more efficient operations and enabling plants to meet increasingly strict daily effluent limits. Added benefits include the prevention of struvite scaling and accumulation within the plant and improved dewatering performance in applications where biological phosphorus removal is used.
