Water Filtration Systems
When rain falls, the water has a naturally aggressive, slightly acidic nature. This water then dissolves chalk and / or metallic deposits present in the local rock strata, resulting in ground and borehole water containing elements that would not normally be present in mains water. Contaminants such as Iron and Manganese can cause problems such as poor tasting (and potentially harmful) drinking water & staining of appliances and equipment.
Media
Iron and Manganese can be removed from water by using media which encourages reaction between the contaminant and oxygen present in the water. This reaction forms an insoluble precipitate which can then be filtered out by the media bed. The media acts “catalytically”, which means that although it triggers the reaction it is not used up as part of the process, thus giving long life from a single filter. A choice of media are available, Pyrolox, Filox & Birm. All are based on Manganese Dioxide but with Pyrolox and Filox having more active sites.
System Management & Backwashing
In order to remove accumulated deposits from the filter bed, the water flow through the filter is reversed (backwashed). Water is run to drain at a high flow rate to separate the deposits from the filter media. The control valve completes the backwash cycle automatically at the intervals and times set during the installation
Sterilisation
Private water supplies may contain micro-organisms that can be harmful if consumed. Ultra Violet light is electromagnetic radiation with a wavelength that is shorter than visible light but longer than x-rays. This disrupts the DNA of micro-organisms, preventing them from replicating and thus de-activing their potential for infection. Ultra Violet systems provide a safe, clean and economical method for sterilisation of water supplies.
