A Parabolic-Curvilinear Reverse-Flow Air-Flotation System (PAF) for Removal of Suspended Solids in Sago Starch Production Wastewater Effluents

A Parabolic-Curvilinear Reverse-Flow Air-Flotation Treatment System (PAF) was recently developed for the removal of total suspended solids from sago starch production wastewater effluents. The primary components of the system consist of a parabolic-curved plate, a series of water pumps, an air cur...
