The Intermittent Cycle Extended Aeration System continuous-fill advanced sequencing batch reactor process from Sanitaire – a Xylem Brand, handles small to large flows. All treatment steps occur within a single tank. The process can accomplish biological nutrient removal in a simple-to-operate process system. It produces effluent quality to less than 5 mg/L BOD, 5 mg/L TSS, 3 mg/L TN and 1 mg/L TP and can be converted to meet future, more stringent limits. It has a maintenance-free stainless steel decanter, simplified operation with equal flow and load distribution, and continuous flow capability that allows single-basin operation for periods of low flow and maintenance. 855/995-4261; www.sanitaire.com.
