Struvite deposits in pipes and aerators
AbstractStruvite created maintenance and operational problems in the Ponggol Pigwaste Plant (PPP) in Singapore a few months after the commissioning of the plant. Struvite growth was studied in the laboratory and in pipes and aerators at the PPP. Struvite solubility and removal with addition of chemicals and physical cleaning have been studied. Sulfuric acid removes struvite cheaper and faster than acetic acid. The struvite crystals are MgNH4PO4.6H2O. A general formula for the prediction of the growth rate and control of deposition of struvite crystals in the shaft section of floating aerators in the aerated anaerobic lagoon (AAL) in the PPP was developed from experimental data.
