Biosand Filter in Southwestern Coastal Bangladesh

 There are lots of drinking water ponds in the coastal area. People cannot  drink the water because of turbidity and other bacterial contamination. Bio-sand filter is a viable water treatment technology in households level. The filter was designed by Dr. David Manz in the 1990s and has been widely tested since that time. It is made out of locally available materials. LEDARS introduced this technology in the coastal area since 2007 with support of CAWST and MIT. Since 2015 LEDARS started this project in the southwestern coastal area with support of OHorizons, USA using wood molds. In this project LEDARS is establishing a filter production center and distributes 1000 filters for 1000 families in 2016. This filter treats the surface water for microbiological contamination and, therefore, is used primarily to treat sweet pond water. From 2017, LEDARS started its 2nd phase project, by which LEDARS will install 200,000 BSF in coastal area of Satkhita, Khulna and Bagerhat district.  Read More
