Dynaflow Inc. introduces the DynaPerm® system for enhanced high flux rate filtration of particles from liquids. Lab testing of the new system shows a flux rate increase of a factor of 50 over conventional cross-flow filtration with comparable or improved effluent quality, the company reports. The DynaPerm system utilizes thick-walled microporous plastic tubes to increase the flux rate through a process combining cyclone separation, flow interruption and cross-flow filtration. The system is ideal for pretreatment prior to RO, carbon adsorption or ion exchange, as well as liquid reuse, treatment of discharge, dewatering or heavy metals removal.
