DynaPerm® system is designed for enhanced high flux rate filtration of particles from liquids. Laboratory experiments with this technology have produced flux rate increases of a factor of 50 over conventional cross flow filtration with comparable or improved effluent quality. System is a cross-flow microfiltration concept which utilizes thick-walled microporous plastic tubes. Micron range pore size and structure can be controlled during manufacturing. Tubes made from a variety of thermoplastics are rugged and chemically and biologically inert. System increases the flux rate and thus economy of particle removal from liquid by combining features of cyclone separation, flow interruption and cross-flow filtration resulting in greatly increased flux rates for near complete removal of suspended particles down to the micron size.
