Discharge of untreated domestic wastewater often leads to eutrophication of receiving water body and create a septic condition, and accelerate sewage sickness in case of land-disposal. However, since domestic wastewater is recognized as nutrient rich water, the recovery of nutrients using a chemical precipitation and crystallization technique may provide value added product struvite, which is a slow releasing fertilizer. This research work shows the techno-feasibility struvite precipitation as an attempt for improving water quality, with simultaneous recovery of struvite as byproduct.
