The ultrafiltration (UF) module is made of high-strength hollow fiber membranes, which have excellent characteristics and advantages: a nominal pore size of 0.03 microns, used to remove bacteria, viruses, and particles, including colloids, to protect downstream processes. For example, reverse osmosis PVDF polymer hollow fibers have high strength and chemical resistance, making the membrane lifespan long. Hydrophilic PVDF fibers are easy to clean and wet, helping to maintain long-term performance in external flow configurations, and high resistance to feed solids, Helps to reduce the need for U-PVC shells for pre-treatment processes and eliminates the need for expensive pressure vessels.

Matters need attention
The effect of wastewater treatment depends on the input water quality, this includes: concentration, the amount of metal containing, COD, suspended particle, suspended particle, organic matter etc. Thus water analysis and membrane experimentation should be made before wastewater goes into the membrane system, besides reasonable wastewater pretreatment is also needed, unqualified wastewater is prohibited from entering into membrane components of the system, because of the high concentration organic solvent in wastewater will destroy the membrane surface and tubular membrane. Thereby blocking the membrane pores and causing water flux decline ,impact membrane system function and efficiency.
