Low-Cost Membranes for Nanofiltration and Reverse Osmosis Water Purification

摘要

ITN has developed a proprietary nanocomposite water filtration membrane that outperforms state of the art membranes with the following attributes: (1) Excellent selectivity (passing water while rejecting contaminants); (2) High water flux (gallons of clean water per minute produced); (3) Chlorine Tolerance; (4) Anti-Fouling (extended clog-free operating times); (5) Durabilty (long lifespan without leaking, breaking, or losing functionality); (6) Low cost. ITN's membrane design includes a selective layer made from an inexpensive polymer fabricated onto a robust support to provide good water flow at relatively low pressure, which eliminates the energy and equipment costs of high-pressure pumps. Energy savings can be up to 30% [1]. In addition, the advanced chemistry of ITN's membrane ensures significantly longer membrane life without the fouling (clogging) that occurs with state of the art membranes.
