Cross Flow Technology for Treating Organics in Wastewater

Over 70 million tons of organic waste is produced in the United Sates each year with many being non-edible sources such as livestock manure, agriculture wastes, wastewater, and inedible food wastes.  If improperly managed, these organic wastes pose a significant risk to the environment and public health due to the presence of pathogens, chemicals, antibiotics, and nutrients that may contaminate surface and ground waters through runoff or by leaching into soils as well as result in algal blooms, harm wildlife or further reduce the quality of surface waters.  

Crossflow membrane filtration has become an effective operation in for organic waste treatment, providing reliable and consistent  filtration with easy maintenance, low labor costs and can be aggressively cleaned-in-place. After the removal of any large abrasive particles, Scepter has been effectively used to create clean water from anaerobic digester run-off without the addition of polymers or processing aids, significantly reducing the operation cost and allowing for direct discharge or reuse.  Scepter membrane has also been used to reduce stillage disposal while reducing freshwater consumption through beneficial reuse, and offer a smaller footprint with reduced energy consumption as compared to a traditional system with centrifuges and evaporators.
