In many parts of the country and particularly in the South West, water supplies from boreholes and wells can contain unacceptable levels of Iron and Manganese.

This can cause an unpleasant taste and also discolouration of sinks, baths, washing, dairy equipment etc. The build up of deposits can eventually result in partial blockage of pipes, ballcocks etc.

Furthermore, it is now a legal requirement for all private water supplies to comply with the required standards of the Private Water Supplies Regulations 1991 which is available from the Drinking Water Inspectorate.

The maximum permitted levels for Iron and Manganese in drinking water are 0.2 mg/l and 0.05 mg/l respectively. (200 & 50 µg/l)

The Shakesby range of filtration units have been designed to remove high levels of iron and manganese simply and efficiently with minimal maintenance requirements.

Shakesby have designed an advanced range of filters that all use the available water pressure to induce air into the water which then comes into contact with a catalytic filter media. This has the dual function of accelerating the oxidation process and retaining the resultant precipitates. This unique air induction system ensures that efficiency levels are maintained for longer and servicing is less frequent. Since the oxidation takes place within the filter itself the danger of iron deposits obstructing pipework is minimised. After a pre-determined period the accumulated oxidation products are automatically washed out of the filter. An advanced air scour system makes this backwashing action extremely efficient and greatly increases the interval between services.
