Arsenic biosand filter

An arsenic biosand filter is a water treatment device that removes arsenic and other contaminants using a layered sand bed combined with beneficial bacteria. As water passes through, the filter's sand traps particles and heavy metals like arsenic. The bacteria develop naturally within the filter and help break down organic impurities, enhancing overall water quality. This eco-friendly, low-cost method improves safety for household use, especially in areas where arsenic contamination of groundwater is a concern. Regular maintenance ensures the filter continues to effectively reduce arsenic levels, providing communities with cleaner, safer drinking water.
