Borehole Water Treatment | North Yorkshire
This water treatment system was installed for a domestic household with a borehole water supply.
This borehole water treatment system was required as the borehole water is very acidic (low pH). It also had had exceptionally high levels of bacteria. We included a pH correction system along with a water storage tank, booster pump, UV steriliser and UV pre-filter.
Removing the sediment, before the water enters the UV, allows the UV light to penetrate all the water. Without pre-filtration, bacteria can “hide” in the shadows of the particulate and evade the UV light. This is known as shadowing.
How much water can a borehole produce per day?
All boreholes are different as they vary in depth and are drilled into different water aquifers located underground. Some boreholes produce thousands of litres of water a day, others are only able to produce a few hundred litres a day.
Whilst most boreholes are free to use, some boreholes – where the extraction is over 20,000 litres of water a day – will need an extraction licence. Extraction licences are issued by the Environment Agency. For more information on extraction licences click > here
pH Correction
Water in which the pH is below 7 is acidic. Acidic water accelerates corrosion in pipe work, causes staining of baths, sinks and other appliances and can leave a distinctive ‘metallic’ taste to the water.
Bacteria
The UV-PRO range of ultra violet sterilisers are versatile units for domestic applications designed to kill waterborne bacteria using the proven method of exposure to ultra violet light.
Water Testing
The starting point for any water treatment design is a representative water analysis that is complete and accurate. Two of Prosep Filter Services engineers have undergone formal training and are now certified to carry out water sampling to UKAS accredited standards. We use a UKAS Accredited Laboratory for all of our water samples.
