Filter Clean
& Media Change

Organic contamination of filter media due to deposition of proteins, sugars, urea, cells, lotions, and other materials from bather loads, coats each particle in the filter and provides a biological glue that sticks particles together under the pressure across the filter. As the organic contamination builds up over time, individual media particles can become larger and larger clumps that eventually form solid “rocks” of sand, glass, or synthetic media that provide no filtration at all.

Backwashing particulate filters is the time-honored method to “clean” the filter media. By forcing pool water in reverse, backwashing is designed to remove debris from the filter and send it to wastewater. The problem with traditional backwashing is that organic contamination is very sticky and water flow is not enough to remove the molecules from the surface of the media particle. In fact, as this process of gluing the particles together continues channels are created in the media that directly connect the laterals to the media surface. Water always follows the path of least resistance and the physics of laminar fluid flow means that there becomes very little interaction between the water and the particulate filter media during filtration and backwashing as these channels develop. Our New FLushing technology enables us to scoure the filter which effectively removes organic contamination in particulate filters. We also developed a method of breaking up the media using a combination of chemicals and air scouring. All services offered along with Swimming Pool Maintenance and Swimming Pool Servicing.
