Hollow Fibre Membrane
Primem is capable of making both reinforced and homogeneous hollow fiber membranes and the hollow fiber membranes are made of PVDF (polyvinylidene fluoride), one of the best polymerous membrane materials with superior chemical stability and strong resistance to high temperature, oxidation and tough conditions like various industrial effluents and municipal wastewater. The membranes are characterized by
1. high porosity and high flux
2. antifouling and easy to clean
3. long service life
4. low operation pressure and low energy consumption
