Municipal and Industrial Water Treatment Case Study – Global
Case Study | Global – Claris® Series Melt Blown Filters
Claris Filter Cartridges from Aria Filtra™ 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 increasing filter costs.
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. Not only is the cleaning experience unpleasant, but the contaminant penetrates the filter cartridges and coats the RO membrane.
The Solution
Aria Filtra’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.
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. Because the on-stream service life can be extended, there are reduced filter costs in addition to fewer change-outs.
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%
