Toray HFU-B2315AN Membrane

Product Description

Toray's HFU-B2315AN pressurized hollow-fiber ultrafiltration (UF) membrane module applies advanced PVDF membrane chemistry and thermallyinduced phase separation (TIPS) spinning method that carefully controls the pore size and evenly distributes the number of pores on the membrane surface. The result is a hollow-fiber membrane with fine separation of viruses, bacteria, and suspended solids, low fouling, and high permeability all to help optimize and extend plant performance.
