Temporary Solutions for Multimedia Filtration from Boreholes: What Are Your Options?

Water quality from a borehole can change over time due to various factors such as changes in the surrounding environment, pumping rate, and groundwater recharge rate.

Mobile solutions can be an option for some seasonal or temporary requirements. Various rental companies offer mobile multimedia units for hire. Sand filters are commonly used to improve borehole water quality by removing suspended solids, organic matter, and other contaminants. They provide:

  1. Improved water clarity: Sand filtration can remove suspended solids and turbidity, making the water clearer and more aesthetically pleasing.
  2. Improved taste and odor: Sand filtration can help to remove organic matter, which is a common cause of unpleasant tastes and odors in water.
  3. Increased water safety: Sand filtration can help to remove contaminants that can be harmful to human health, such as bacteria and viruses.
  4. Enhanced water treatment: Sand filtration can serve as a pre-treatment step before other forms of water treatment, such as reverse osmosis or ultraviolet disinfection, to improve the effectiveness of these processes.
  5. Increased water quality: Sand filtration can help to maintain the water quality of the borehole by removing contaminants that can affect the water’s chemistry and mineral content over time.

The effectiveness of sand filtration depends on the contaminants present in the water and the size of the sand particles used in the filter, and it is not a substitute for other forms of water treatment.

An example is shown where a mobile multimedia unit is fed from a borehole through a manifold system controlled by actuated valves which initiate a backwash sequence after a predetermined period.
