Assessment on biochemical oxygen demand (BOD) removal using treatment train system for agricultural run-off

Agricultural runoff is non-point source pollution that unpredictable and difficult to control. Best Management Practices (BMPs) Low Impact Development (LID) has been utilized as a method manage agricultural runoff. Treatment train systems are LID-BMPs arranged in series aims treat This study focuses on the use of treatment reduce concentration BOD A system was set up with three varying configurations evaluate efficiency removal. The consisted no vegetation which acts control, vegetated set, saturated zone. All showed good final removal rates at 56% for control 75% 85% both sets without classified classifying it Class III according Water Quality Standards, while zone had II I, respectively. performance compared single bioretention system.
