Removing Heavy Metals from Borehole Water: A Practical Guide

Removing Heavy Metals from Borehole Water: A Practical Guide

Achieving total water independence and a sovereign water supply is a key component of disaster-proofing your family’s future. In many parts of Kenya and East Africa, boreholes are a common source of drinking water, but they can also be prone to contamination by heavy metals such as lead, arsenic, and mercury.

Eliminating these contaminants requires a multi-stage treatment process that addresses both the physical and chemical aspects of water quality. In this guide, we will walk you through a practical approach to removing heavy metals from borehole water using proven technologies and components.

Step 1: Pre-treatment – Sedimentation and Filtration

The first line of defense against contamination is pre-treatment. A sediment pre-filter can be used to remove particulate matter, sediment, and other suspended solids that may contain contaminants like lead or arsenic. A common component for this stage is a stainless steel pressure vessel with a built-in sediment pre-filter.

Step 2: Activated Carbon Filtration

Activated carbon filtration is effective in removing dissolved solids, including many heavy metals. A ceramic filter with an activated carbon core can be used to achieve water quality that meets international standards. This stage is critical for removing volatile organic compounds (VOCs) and other contaminants that may not be addressed by subsequent treatment stages.

Step 3: Reverse Osmosis Membrane Filtration

Reverse osmosis membrane filtration provides the most effective method of removing dissolved solids, including heavy metals, from borehole water. A high-quality RO membrane with a pore size of 0.0001 microns can remove virtually all contaminants, including lead, arsenic, and mercury.

Step 4: Disinfection – UV-C Lamps

Disinfection is the final stage in our treatment process. UV-C lamps are highly effective against bacteria, viruses, and other microorganisms that may be present in contaminated water. This step ensures that your water supply is not only free from heavy metals but also safe to drink.

Implementation Considerations for Kenyan/African Context

In regions where municipal water supplies fail or are unreliable, borehole water becomes the most critical source of drinking water. In Kenya and East Africa, there is a high risk of fluoride contamination in boreholes due to geology and hydrology. Our treatment protocol takes this into account by including an activated carbon stage specifically designed to remove fluoride.

Conclusion

Removing heavy metals from borehole water requires a multi-stage approach that incorporates physical and chemical treatment technologies. By following our practical guide, you can achieve permanent water security for your family and eliminate contamination risks for good.
