Reverse Osmosis Membrane Increases Efficiency and Offers High Recovery Rate

Publication Date: 
May 18, 2015

Point-of-use reverse osmosis element design, specifically the distribution of feed water to the membrane, has remained somewhat static since the introduction of thin layer/film composite (TLC) or non-cellulose membranes. Most reverse osmosis systems, depending on design and operating conditions, dispense 70 to 90% of feed water to the drain. Many RO systems use a similar membrane and distribute water through the element in the same manner, so there is little opportunity to increase the system’s efficiency.

Breathing New Life Into Membranes

Point-of-use (POU) reverse osmosis (RO) membranes often get a bad rap within the water treatment industry for a few reasons: It is a saturated, commoditized market with slimmer margins; there have been minimal technological advancements in system performance; they have a high percentage of wastewater to drinking water; and consumers are demanding greener, less wasteful products.

Sulfate Removal Membrane

Company Reference: 

NFS is a nanofiltration (NF) membrane formulated to deliver sulfate rejection and flux performance in sulfate removal applications. In addition to exhibiting high mechanical strength and durability, the membrane provides a 30% increase in flux efficiency and more than 99.5% average sulfate rejection when tested under typical seawater operating conditions. This type of NF technology is ideal for enhanced oil recovery during water flooding processes through the prevention of scaling and oil well souring.
