Clack Organic Scavenger Water Filter

Wateq’s organic scavenger units reduce the discolouration of water by removing organics present in the raw water. Discolouration in water is extremely common in private water supplies, most commonly as iron and manganese. However if the incoming raw water is low in iron and manganese and you are still encountering discoloured water then this is likely a result of elevated organic levels, referred to as tannins. Tannins are a result of water passing though peaty water and decaying vegetation.

Our Organic Scavenger units come complete with two different types of anion selective resins specifically designed to reduce tannins. Please be aware that these units require a larger dose of sodium for regenerations and regeneration is typically based from an onsite assessment of the severity of the water.

These units are always recommended as the final stage of filtration. If you require any advice on sizing and specifying these units, please do not hesitate to get in touch.
