Due to the decommissioning of the AFS activated sludge WWTS, wastewater was being sent to the municipal WWT plant. Due to more stringent municipal regulations, the WWTS needed to be recommissioned incorporating design improvements. It was determined that irregular influent flowrates and alkaline wastewater sources were major contributors to system inefficiency. To accommodate high flowrate fluctuation, the first aeration and settling tank was evaluated for use as an equalization basin. This would allow flowrate and BOD to be regulated, while improving effluent quality. A pH adjust system was also incorporated into the recommended design. With these improvements, AFS should meet discharge requirements and achieve high quality wastewater effluent on- site for irrigation.
