A filtration - adsorption hybrid system in tertiary wastewater treatment

Project Member(s): Vigneswaran, S.

Start year: 2002

Summary: Deteriorating water quality in waterways necessitates superior tertiary treatement in sewage treatment plants. A new hybrid system consisting of filtration and adsorption processes can be a cost effective system in removing solids and organics from sewage. A mathematical model will be developed by incorporating particle size distribution in filtration and organic species characterization in adsorption. We will then verify the model using experiemental results, and estabilsh a methodology for the optimization of this system. This system will also be investigated with an intermittent washing for filtration and porous polystyrene medium for adsorption in view of reducing the operating costs.
