The Sand in Biosand - Getting to the Heart of the Biosand Filter - Webinar

The most important part of the biosand filter is the filter sand. It is the sand that does the actual work of removing dangerous pathogens from the water. Biosand filters can come in all shapes and sizes, with filter containers successfully being made from concrete, plastic, PVC, ferrocement, sheet metal, and other materials. However, if the sand is not right, the filter will not work. This webinar goes over the most important aspects about filter sand, reviews the latest research, and addresses common questions and challenges people run into in their projects.
