Abstract
A system and method for algal harvesting and destabilization are provided. The system includes a multifunctional reactive electrochemical membrane (REM). The application of an electrical current generates reactive species at the REM surface and oxidizes algae and soluble organic compounds. This novel type of membrane filtration avoids the use of harmful chemical additives. In addition, it provides the benefits of avoiding polymer aging, membrane fouling, and high costs caused by high transmembrane pressures and frequent membrane cleaning. Traditional membrane separation that significantly suffers from membrane fouling due to either the formation of a cake layer of algal cells, or more commonly due to organic matter adsorption onto the membrane surface is significantly avoided.
