Water Filtration

SCL Water recommends that a water sample is taken from your own private supply, following a Flow Test and analysed under laboratory conditions. The geographical location will have a major bearing on depth, quantity and quality of supply. In any event the water can be analysed to establish contamination and to establish what filtration is necessary to raise the quality of the water to the 2000 Drinking Water Standards.

 

The simplified diagram below shows a typical filtration system to remove commonly found chemical contamination such as iron and manganese. It also shows inline ultra violet sterilisation (U/V) that destroys bacterial contaminants.

 

The filtration included in the logical schematic is as follows:

• A sand and gravel filter that extracts iron found in suspension.
• A Crystal Right unit that removes iron and manganese in solution and can raise the PH
• A filter housing and sediment filter to remove particles.
• An Ultra Violet (U/V) sterilisation unit to destroy any bacterial contamination that may be present.

The sand, gravel and crystal rite units self clean on a regular basis by the process of backwashing using a saline solution. This cleansing process creates a quantity of water that should be run to ground via a soakaway.

 

SCL Water install a pressure vessel that will protect your borehole pump from overloading and provide a buffer supply to your property.  The pressure vessel, together with the system control panel and any filtration should be on a site close to your property and undercover. An outbuilding or shed is ideal. A supply of mains electricity is required (Single or 3-phase).
