Abstract
One of the ways to reduce the pollution of rivers is to treat wastewater at the source point. This can be accomplished by building a Biologically Active Filter (BAF) at source point of drainage system to treat the wastewater before it is being discharged into the river. The BAF is distinguished from other filtration system because there is a separation between the microorganisms and the treated wastes. The method of filtration is a combination of both physico-chemical adsorption and in-situ bioremediation. A bench scale BAF was setup using natural materials as its filtering media. Indigenous microorganisms from the wastewater with optimum pollutant degradation capabilities have been isolated and added into the BAF, to enhance the biodegradation of wastewater. With its biological regeneration capabilities, this system should serve as a sustainable, effective, and economic filtration method for various industrial wastewater and discharge. Influent and effluent qualities have been evaluated based on physical, chemical and biological parameters.
