Abstract

Biofiller, a single pass aerobic biological treatment has been widely used for wastewater treatment. Due to the emerged of the biofilter application in wastewater treatment, this study was conducted to asses the performance of the biofilter-in. treating greywater. The effects of the dosing rate were investigated. In this study, 2-4 mm brick biofilter was used. The intermittent dosing rate was evaluated in the treatment of greywater. Wastewater effluent dosing rates were intermittently sprayed with lower dosing rate at 3.5 min spraying and 6.5 interval dosing; medium dosing rate at 6.5 min spraying and 3.5 min interval; higher dosing rate using continuous spraying. The BOD removal was decreased as results of increasing the dosing rate. In all dosing rate, the higher BOD removal rates was observed in biofilter with lower dosing at 3.5 min spraying, followed by medium dosing rate at 6.5 min spraying. The least BOD removal was observed in high dosing rate at continuous spraying. This indicates that intermittent dosing with lower dosing rates important and efficient for BOD removal.
