Nanofiltration Membranes As A Wastewater Treatment Solutions
Wastewater Treatment Solutions
Nanofiltration is a separation process characterized by organic, thin-film composite membranes with a pore size range of 0.1 to 10nm. Unlike reverse osmosis (RO) membranes, which reject all solutes, NF membranes can operate at lower pressures and offer selective solute rejection based on both size and charge.
Nanofiltration membranes are a relatively recent development, and offer greater selectivity of ions vs. reverse osmosis membranes that reject all ion species in a feed stream. This unique characteristic provides flexibility in separation process development that can greatly impact performance and profitability, especially for industrial applications.
