Colour & Tannin


Water containing organics (plant and animal matter) can appear “stained” or coloured; typically appearing as brown, green or yellow. This is often not harmful, but will be treated for aesthetic reasons. Coloured water can also be an indicator that other contaminants are present in the water that can be harmful, such as iron, manganese and sediment.

Treating colour and tannin in water is done using an anion exchange resin. Resinex TPX4501 is a pre-washed, high purity, strong basic macroporous-type anion exchange resin, offering excellent mechanical and chemical stability. TPX4501 removes organics from the water, returning the water to its colourless appearance. It is also regenerated using standard softener salt.

It should also be noted that if you are running a UV Disinfection system, then removing the colour or tannin from the water is a necessity for ensuring the UV System is operating at maximum efficiency.
