The biggest problem that is considered when using reverse osmosis membranes is membrane fouling.
In particular, when surface water or wastewater is used as raw water, they often cause pollution that is difficult to recover due to the high concentration of organic matters. The fouling-resistant reverse osmosis membrane developed by CSM’s latest technology has significantly reduced the problem. As hydrophilicity is improved, the deposition of hydrophobic substances (oil, organic substances, etc.) is reduced, and particle sedimentation is also reduced due to the smooth surface of the membranes. Therefore, they have superior fouling resistance characteristics compared to those of existing products in wastewater with high organic content.
