Case Study: Cartridge Filters – Extending RO Membrane Efficiency

Pall Water's Claris® Filter Cartridges are shown to extend the efficiency of reverse osmosis (RO) membranes and reduce subsequent fouling when compared to traditional string wound filters. Switching to Claris can enable facilities to increase in filter performance, without an increasing filter costs.

Case Study: Extending RO Membrane Efficiency

Municipal & Industrial Water Treatment | Global

Traditionally, reverse osmosis (RO) plants use string wound or melt blown polypropylene prefilters to protect the more costly RO membranes. During change-out, a stringy, slime-like substance is often found covering the inside of the filter housing. The presence of this substance causes downtime and a mess that requires clean-up by maintenance engineers. Not only is the cleaning experience unpleasant, but the contaminant penetrates the filter cartridges and coats the RO membrane. 

 

Pall’s Claris® Series melt blown filters were tested in place of string wound filters, and the results were outstanding. With the Claris filter cartridge, your facility may no longer experience fouled membranes due to the design and contruction of these filters.

Solution Overview

  • Reduced Downtime: Less downtime for cleaning prefilter vessels and costly RO membranes, thus reducing overall costs
  • Quality Filters: Claris filters did not unload contaminants, leading to improved RO membrane protection and longer service life
  • Reduced Cost: Extended filter life, coupled with lower unit filter cost, can reduce total filtration by more than 50%
  • Fewer Filter Change-Outs: Can be reduced by 50% due to longer on-stream life cycle of Claris filters

  • The Challenge

    Traditionally, Reverse Osmosis (RO) plants use string wound or melt blown prefilters to protect the more costly RO membranes. During change-out, a stringy, slime-like substance is often found covering the inside of the filter housing. The presence of this substance causes downtime and a mess that requires clean-up by maintenance engineers.

  • The Solution

    Pall’s Claris® Series melt blown filters were tested in place of string wound filters, and the results were outstanding. With Claris filters, concerns that contaminants would pass through the cartridge filters are eliminated. Furthermore, on-stream service life can be extended, thereby reducing filter costs as well as the number of change-outs.

  • The Results

    The Claris filter cartridge is manufactured using a highly automated process that produces an extremely consistent product with a low unit cost. The long, on-stream life cycles of the Claris filter are attributed to the high void volume, which provides improved dirt holding capacity. The Claris filter also features a patented extruded fibrous core design.
