Nutrient Removal from Synthetic Wastewater Using Sequence Batch Reactor SBR in the Attached Growth System

Microorganisms in household wastewater streams pose a risk to human health since they can be toxic or cause illness. Traditional wastewater treatment plants in Malaysia continue to fall short of the country's strict discharge standards. Compliance with discharge criteria to satisfy ammonia and nitrate levels is necessary due to stringent regulation enforced by regulatory entities. It is suggested that the system utilise a submerged attached growth in order to achieve these constraints. The Palam Oil Clinker POC may be integrated into existing water purification infrastructure. This study established a comparison between traditional activated sludge and submerged attached growth-activated sludge systems for treating synthetic domestic wastewater (DWW). Medium-strength synthetic residential wastewater was used in a sequential batch mode investigation to find the optimal conditions for removing NH4, NH3, and PO4. Removal efficiencies for NH4+N, NH3, and TP were 91 mg/L, 89.4 mg/L, and 80 mg/L, respectively, after studying the effects of cycle time (CT). This was accomplished in a biofilm batch reactor with sequentially connected growth that was kept submerged. According to the optimisation analysis, CT should be performed over the course of 72 hours. Predicted mean responses for the best solution were 91 mg/L for NH4+N removal, 89.4 mg/L for NH3 removal, and 80 mg/L for TP removal.
