The biosand filter offers a proven and practical method for treating water at the household level. Water is poured into the top of the filter and passes slowly through layers of specifically prepared sand and gravel. As the water moves through the filter, contaminants are removed through filtration, adsorption, and biological processes that develop naturally within the sand layer.
The filter is effective at removing harmful microorganisms, resulting in safer drinking water. It does not require electricity or complex operation, making it suitable for low-resource settings. With proper use and maintenance, the biosand filter can provide a long-term solution for improving drinking water quality.
