Membrane fouling has been one of the main causes of operations problems with reverse osmosis (RO) systems. A new low fouling RO membrane element (TML20-365) has been developed to help alleviate these problems. This new low fouling RO membrane element will be advantageous for processing municipal, industrial effluent, and surface waters, which in the past have been difficult to treat with normal conventional RO elements. This new low fouling RO membrane is a cross-linked polyamide composite membrane with surface modification. TML20-365 exhibits excellent performance in reducing membrane fouling from chemical and biological sources found in wastewater effluent applications. This RO membrane shows similar or superior water permeability and separation performance over those membranes used in conventional low-pressure RO elements.
