Abstract:
In this work, results of using dynamic and conventional filtration systems and different membrane materials are presented. Huge permeability improvement was obtained. In some cases, fouling was almost eliminated. For a given plant yield, membrane area required is much smaller in dynamic filtration than in conventional one. It lets decrease investment cost, which was found to be more sensitive than operational one. Moreover, this cost could decrease even more if materials with lower price than conventional one are used. The combination of sedimentation and membrane dewatering was also investigated which allowed a reduction of harvesting time without affecting membrane performances.
