Submerged Membrane Module
NTi membranes are made from high-performance polyvinylidene fluoride (PVDF) using the next generation of thermally induced phase separation (TIPS) process, which offers exceptional hydrophilicity, strength, flux, and chemical resistance. The manufacturing process is completely environmentally friendly and free from harmful or toxic chemicals.
