Nanofibers in Practise Process and Energy Cost cost/m2 50% lower For treating ~ 100,000 m3 capacity of water annually, one should have minimum two cartridge filters based on current scenario. On the other hand, one NAFIPOR cartridge is sufficient to filter the water of that capacity, reduces investment cost & also saves energy. Nanofibers in Practise Economy 100,000 m3 – 6MWh The total potential of the Chinese market is enormous – at current estimated consumption 60 liters/person/day. Nanofibers in Practise Conclusions from the Samples Measurement We have tested three various nanofibrous microfiltration membranes with the maximal pores between 0.20 to 0.35 microns. Permeability of membranes to water (pure water flux) ranges around 16 000 l/m2.h.bar for all tested samples, which is sever times higher than the commercially available microfiltration membranes with similar pore size. Pure water flux should be probably further improved.
