FEED SPACER INNOVATION FOR REVERSE OSMOSIS APPLICATIONS
Our R&D team thrives on developing customized feed spacers for each customer application.
Conwed manufactures a full line of feed spacers specifically designed for reverse osmosis applications. Frequently known as scrim, mesh, net, or netting, feed spacers act as one of the layers of wound materials in Reverse Osmosis (RO) filters and provide vital separation between the membranes to achieve superior filter performance.
Reverse osmosis is a critical part of the world's water supply. The International Water Management Institute, a non-profit scientific research organization that focuses on sustainable water use in developing countries, estimates that by 2025 nearly 1 billion people will lack access to fresh, drinkable water. It's clear that RO will play a major role in alleviating water scarcity, but there will be a strong push for greater efficiency and cutting energy costs while boosting product water output. Conwed believes that the next leaps in RO filtration efficiency could come from the feed spacer.
Conwed designs feed spacers for industrial water applications, brackish water reverse osmosis (BWRO) and seawater (desalination) reverse osmosis (SWRO) systems.

3. ULTRA HIGH POROSITY™ (UHP) FEED SPACERS FOR BRWO SYSTEMS
Conwed developed feed spacers with a higher porosity ratio to improve water pressure drop in BWRO systems while maintaining equivalent flux and biofouling performance when compared to standard feed spacer configurations. Porosity, also known as void fraction, is the ratio of open (empty) volume to solid volume of the feed spacer. In simple terms, a high porosity feed spacer has more void –empty space– volume, whereas a low porosity feed spacer has less void volume.
