Hongtek UFP160 Series 6" PVC UF Membrane Module is made of high quality modified PVC hollow fiber ultrafiltration membrane. PVC ultrafiltration membrane has internal and external double cortical structure, and the effluent is filtered by double layer. Hollow fiber PVC membrane can still guarantee excellent filtration effect under the operating conditions of frequent fluctuation of raw water and poor water quality. End cap and clamp structure make UFC160 Series PVC UF Membrane module pressure capacity exceed 1MPa. PVC ultrafiltration membrane has good anti-aging, acid and alkali resistance and chemical stability. 6" Industrail PVC membrane module is small footprint, compact design, modular design for medium-sized water treatment systems.

Work principle of PVC ultrafiltration membrane
● Hollow fiber PVC membrane water flow mode is from inside to outside
● PVC ultrafiltration membrane is resistant to acid and alkali and has good drug resistance
● PVC UF membrane module can be used in cross-flow filtration or dead end filtration operation
● PVC ultrafiltration membrane is low pressure operation, low energy consumption and cost saving
● Rating is 0.01 micron, particles such as macromolecules, suspended solids and colloids are trapped inside
● The impurities are trapped on the inner surface of the membrane silk, there is no dead angle problem and easier to be washed
