The researchers studied ways to improve wastewater treatment for reuse by combining microfiltration with enhanced flocculation and adsorption processes. They found that adding powdered activated carbon as a pretreatment to microfiltration resulted in high removal of organic contaminants. Using both flocculation and adsorption as pretreatments led to even higher removal efficiency and stable filtration flux. Operating the system at a constant filtration flux below a critical level increased the effectiveness of organic matter removal. Preadsorption before membrane operation helped reduce membrane fouling, and specific aeration rates, filtration flux, and PAC dosing were found to be optimal for the wastewater tested.
