|Title:||Nanofiltration Membranes as a Suitable Alternative to Reverse Osmosis/Ultrafiltration Membranes in Separation Processes|
Shah, V J
|Abstract:||The paper reviews on thin-film composite membranes covering membranes, nanofiltration membranes, their advantages over other separation techniques and utility.Focuses on a limited area comprising nanofiltration (NF) membranes which appear as a suitable alternative to reverse osmosis (RO) and ultrafiltration (UF) membrane processes. Nanofiltration (NF) has emerged as a promising area which has extended membrane applications.NF membranes are generally polyamide membranes and are charged. They have higher flux and lower salt rejection facilitating a diverse cut-off based on molecular weight of a specie with more than 92 per cent rejection. N F membranes are considered to be best alternative of purification.|
