Improving Pre-RO Filtration With 3M™ High Flow HFR Series Filters

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.
