A borehole is vertical or horizontal shaft drilled into the ground to extract water. A supportive outer shell is normally constructed in the borehole to prevent it collapsing in on itself. Strict guidelines have been put in place for the treatment of water from this type of source due to the array of problems that follow its use.
A common problem that is encountered with borehole water is high levels of water hardness, which is known to produce a build up of scale (calcium and magnesium ions) within pipes and filtration systems. High levels of nitrates are also prevalent within water drawn from a borehole, making water unsafe to consume. Whilst these contaminants can usually be controlled using reverse osmosis, their high levels from source call for pre treatment stages of water softening and nitrate removal.
Excess turbidity, iron and manganese are also common factors within borehole water that affect the potability of this source. Our extensive range of particle filtration is perfect for removing suspended solids at different micron ratings. This is furthered by other mechanical types of filtration within our systems such as the use of our carbon cartridges. Not only do these aid in particle removal, but also are great at absorbing organic, volatile compounds such as chlorine, chloramine and heavy metals.
Bacterial contamination and PH imbalances are bound to occur when water is stored underground. Whilst the majority of the bacteria will be removed with particle filtration and reverse osmosis, the latter also controlling PH levels within the water, we recommend using UV sterilisation to control the future growth of bacteria.
