Advanced micro filtration - DynaPerm®
Available from Dynaflow Inc
DynaPerm® is a system for enhanced filtration of particles from liquids. Laboratory experiments have produced flux rate increases of a factor of 50 over conventional cross flow filtration with comparable or improved effluent quality. The initial efforts to develop the technology were funded by Small Business Innovation Research (SBIR) awards from the National Science Foundation.
DynaPerm® is based on a cross-flow micro filtration concept which utilizes thick-walled micro porous plastic tubes. The pore structure and micron range pore sizes are controlled during the manufacturing process. These tubes can be made from a variety of extrudable thermoplastics, are rugged, and chemically and biologically inert. A conventional cross-flow filtration technology, HYDROPERM, using these micro porous tubes has been successfully used commercially for the nearly complete removal of suspended solids and primarily toxic heavy metals.
