Pressurized media filters provide effective solids removal and are a key water treatment component in systems that are not head-limited. Depending on the treatment requirements, media filters can provide physical barriers for particle retention and removal, as well as chemical barriers for dissolved substances such as chlorine or iron.
PR Aqua packages industrial- and institutional-grade, pressurized media filter systems tailored to the specific functionality, flow, and water quality requirements of each facility. PR Aqua can custom design a system around your needs or can provide a system to meet your specifications – either way, PR Aqua has the solutions for your water quality problems.

How It Works
Water from a pressurized source is distributed through screened laterals above the media bed within a pressurized vessel. Water passes down through the interstices around the media. Solids are retained in the media bed by physical entrapment or electro-static attachment; depending on the media used, adsorption and absorption may also be occurring. Filtered water is collected in screened laterals at the bottom of the media bed. Periodic back-flushing, where inlet water enters through the bottom laterals and exits through the top, causes the bed to fluidize and the solids to be released. Back-flush effluent is directed to waste, and normal flow is resumed (with or without a rinse cycle).
