Abstract:

A two-tiered market investigation was conducted for cartridge filters used in the 600 and 3,000 GPH Reverse Osmosis Water Purification Units ROWPUs. The fielded ROWPUs use string-wound, depth filters. It is possible that different designs may be more effective than the current design. The two-tiered investigation involved a preliminary questionnaire to establish type of filters manufactured, followed with a detailed questionnaire to these manufacturers that manufacture cartridge filters which may be used in the target ROWPUs. It was found that pleated, porous cartridge filters provide improved performance in reusability, solids entrapment, and are in a reasonable cost range. The Government must test specific pleated filters with consistent input water to verify andor compare their performance. Keywords Reverse osmosis, Cartridge filter, Pre-treatment, Water purification.
