DYNAPERM® has application in manystream and effluent treatment processessuch as:• Pretreatment for suspended solidsremoval prior to reverse osmosis,carbon adsorption, or ion exchangetreatment• Polishing for removal of fine sus-pended solids after chemical orbiological treatment• Liquid Reuse when this is other-wise impeded by the presence ofsuspended solids• In-Plant Processes for valuablematerial recovery• Toxic Heavy Metals Removal whenin suspended form• Treatment for dischargeDYNAFLOW, INC. is an applied sciences re-search and development company.

The porestructure and micron range pore sizes are con-trolled during the manufacturing process. Thesetubes can be made from a variety of extrudablethermoplastics, are rugged and chemically andbiologically inert.DYNAPERM® enables greatly increased fluxrates with minimal down time for near com-plete removal of suspended particles down tothe micron size.DYNAPERM® tubes pore size distribution.DYNAPERM® filtration components.Example electroplating results with DYNAPERM® tubes.DYNAPERM® filtration rates on water obtainedfrom high pressure jet stripping of rust.DYNAPERM® is a registered trademark of DYNAFLOW, INC.0200040006000800010000120000 100 200 300 400 500 600Time, min.Flux Rate: gal/day/sq. ft.
