Carbon Filtration

Carbon filtration is used widely for de-Chlorination, de-Ozoneation, de-Bromination and organic scavenging. Carbon is also effective and widely used as taste and odour removal or reduction.

Like all forms of media filtration the correct velocity for filtering and backwash is essential, many media systems fail because of poorly designed and inadequate backwash design. carbon filtration design

Column length (contact time) is also an essential part of Carbon filtration design, too short and the desired target removal just won't happen.

As a general guide, if your Carbon vessel is not cleaned after a 6 min backwash, you probably have a problem, most likely with the backwash velocity. in theory Carbon should never exhaust

In theory Carbon should never exhaust, it should continue to function correctly until the grains disintegrate, however the usual demise of Carbon is contamination, once the pores are blocked or covered the Carbon is basically useless. Therefore if long or even reasonable life is expected from your Carbon filter it is vital the water passing over the Carbon is as clean as possible.

WRA specialise in designing these types of systems, ensuring the correct velocities are available for filtering and backwash and providing quality filtered water to maximise Carbon life expectancy.

Carbon has a typical filtering rate of 250 Lit/min/sq metre and a back wash of 500 Lit/min/sq metre.

As with any backwash-able filtration process, carbon filtration can be manual or automated, WRA provide both types.
