3M™ High Flow HFR Series Filter Cartridge Customer Success Stories

Reverse osmosis (RO) pre-treatment is used in industrial water filtration to protect the RO membranes, high pressure pumps and other hardware. The performance of pre-filters matters and can impact your operation, in terms of efficiency and water quality.

The filter surface area, the depth vs. pleated configuration and the nominal vs. absolute rating all play a role in the overall performance of your filtration system. With some pre-RO treatments, such as multi-media filters and activated carbon filters, there is a chance for a variety of contaminants to remain in the water.

Other filters, like traditional melt blown filters, have lower flow per cartridge compared to large format cartridges. Conventional melt blown filters are also usually nominally rated, even though consistent and reproducible contaminant reduction can best be provided by the use of absolute-rated filters.
