Title: REVIEW ON CURRENT TECHNOLOGIES: STRUVITE FORMATION, CONTROL AND NUTRIENT RECOVERY IN WASTEWATER TREATMENT
Abstract: Nutrient recovery, e.g., phosphorus and nitrogen from wastewater discharge is a challenging job as with the nutrients the receiving water does not meet the standards of the regulatory authorities. A wastewater treatment plant (WWTP) has to pay an extra charge for recovering nutrients. Some plants convert nutrients into fertilizer and sell them to the farmers to earn extra credit. The wasted sludge includes magnesium, phosphorus, and nitrogen. The combination of these three ions forms struvite (MgNH4PO4·6H2O). It dominates in the biological nutrient removal (BNR) process. Nutrients can be recovered as struvite. But struvite formation during wastewater treatment causes operational difficulties. The controlled creation of struvite and its recovery have significant commercial value as a fertilizer. This study reviews the current technologies of struvite formation, control, and nutrient recovery in wastewater treatment.
