How to Protect Reverse Osmosis Membranes for Drinking Water Applications

Register for this interactive webinar to learn the ways to optimize the pre-treatment of reverse osmosis membranes in municipal drinking water applications using filter cartridges. Discover the differences between types of filters and understand how they impact total cost of ownership.

Time: 11 AM EDT (8 AM PDT / 5:00 PM CEST)
Duration: 1 hour

An essential step is the removal of total suspended solids to prevent reverse osmosis (RO) fouling in drinking water applications. Pretreatment typically includes conventional filtration such as bag and cartridge filters to remove bulk solids. Although this step is sometimes overlooked, it is critical to the overall process. RO membrane life can be dramatically reduced if this step is designed poorly, increasing the frequency of cleanings and wear and tear on the membranes.

This webinar explains important variables that can impact the life of RO membranes and the total cost of pretreatment, including efficiency, changeout frequency, pore structure, flow and more.

Key Takeaways

  • Learn how to determine the type of filtration needed
  • Discover the difference between filter types
  • Understand how filter specifications impact performance and cost over time
  • Learn how to optimize your RO pretreatment to reduce your costs
