Reverse Osmosis (RO) is a critical part of the world’s water supply. By 2025, nearly 1 billion people will lack access to fresh, drinkable water. It is 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. Frequently known as scrim, mesh, net or netting, feed spacers act as one of the layers of wound materials in reverse osmosis filters and provide vital separation between the membranes to achieve superior filter performance.
The Global Innovation and Technology team at Conwed, led by James Kidwell, is devising and testing new ideas and developments in feed spacers. “We believe the next generation of improved RO feed spacers can lead to increased performance and energy efficiency," he says. "Pressure drop, membrane damage and biofouling are a concern for both membrane manufacturers and RO plant operators. We believe the next leap in RO filtration efficiency could come from the feed spacer”.
Conwed is focusing on the RO feed spacer market following increasing demand for RO filters worldwide. Existing RO plants expanding their water treatment capacity and new plants around the world are becoming operational confirm the growing need for drinkable water. “We proactively took upon ourselves the challenge of understanding how feed spacer design evolution may impact filtration efficiency. We want to become the innovation leader in RO feed spacer development,” sayes Chris Hatzenbuhler, CEO at Conwed.
All Asia, Africa, Middle East and Australia customers, serviced by Conwed European Headquarters, will benefit from the expanded production capacity installed. “We’re delighted with this investment in our European plant. Increasing our feed spacer production capacity confirms our commitment to the reverse osmosis industry. Our ability to customize netting configurations and our in-house testing capabilities make us the partner of choice for RO filter developers,” says Stefan Tielen, General Manager at Conwed Europe.
