pH Water Treatment Units - domestic use
Neutralising filter for acidic water
Naturally occurring acidic ground waters can cause corrosion of pipework, heating cylinders and equipment. The copper is dissolved out of the plumbing and is deposited as blue stains on fittings and fixtures. As heat speeds up chemical reactions, you may see more staining on the hot tap. Any iron and manganese present will result in poor tasting water, in addition to staining baths, basins and any appliances a red or brown colour.
The Filpumps System
The simplest and safest way to raise the pH is to run the water through a vessel containing a bed of specially prepared limestone. This contains calcium and magnesium minerals, which are the salts found in waters of pH greater than 7.0. The limestone gradually dissolves increasing the pH level of the water.
Once this has taken place, the water is less able to dissolve the metal from copper or lead pipes and fittings. As the limestone is used up, it will need refilling periodically.Refilling is straightforward as the media is inert and easy to handle.
The limestone media used in the acid water treatment filter will also remove any particles of sand or silt occurring in the water. To avoid the unnecessary build up of these contaminants in the limestone media, we would strongly recommend the use of a cartridge pre-filter.

A pH value below 7 is considered to be acidic, and corrosion accelerates at pH levels below 6.5, with levels below 6.0 considered to be extremely aggressive
Overall Dimensions of manual upflow domestic unit-

V3006 Bypass Valve for In/Out head - as shown on main picture, allows mixing of raw water where pH balancing is required and also allows system maintenance.
There are two systems available:
Manual up-flow with no media back-washing and therefore access to a suitable drain is not required. This is our most commonly sold system for domestic houses.
Automatic back-washing alternative is required for various different reasons such as the presence of elevated levels of iron and manganese, where these contaminates need to be flushed to waste or for properties with extended periods of non residence to keep the media inside in good condition.
