Reducing Operating Cost, Conserving Resources.

Conventional sand filtration requires vast volumes of treated heated  pool water to clean the sand bed .The Filtrex regenerative media filtration filter provides a resource conserving solution for today swimming pools. Backwashing a 450m3 pool requires approximately 1500 m3 of water a year at today’s prices this equates to a saving of £13,000 a year using Filtrex regenerative technology.

Crystal Clear Water

The Filtrex filter utilizes a system of filter aid regeneration and innovative filter elements called the flex tube. Filtrex regenerative system provides unpatrolled water clarity and remarkable operating efficiency. Filtrex Regenerative filtration filters to 1 micron reducing the risk from cryptosporidium and reducing the turbidity to .049 on the NTU scale Sand filtration best results is normally .49 NTU 10 time poorer.

Space Saving

If a refit is required Filtrex filters up to the EC500 (Flow rate 160m3/hr) model will fit through a normal width door .This will in most cases suit the filtration requirements of a 25M pool This results in as little 75% of the space required by an equivalent sized sand system, saving installation cost and time and freeing up valuable floor space for other productive purposes with commercial building costs at an estimated £600 to £800 per square Meter, selecting Filtrex will reduce the plant room size leading to a significant reduction in building cost

Why Stainless Steel.

The main problem with a carbon steel tank is field longevity. Our stated goal in manufacture is that Filtrex Filters should give an effective service life equal to that of the facility itself. This in our opinion cannot be achieved with carbon steel construction regardless of surface treatments, coatings, linings, and processes. Premium grades of stainless steel used in conjunction with proper welding alloy/practices, shielding gas, and post fabrication passivation will produce a filter tank with a lifespan which can and will (if maintained properly) outlast the facility that it is installed in.
