APPLICATION

The simple technology for a small-scale Water Purification System (WPS) can be applied to the countryside.  Its fabrication applies the typical treatment methods used in the public water system.  It consists of pre-treatment tank, sand filter unit, chlorination tank and ceramic filter unit.

TECHNOLOGY DESCRIPTION

The technology applies the simple system of water purification with the use initially of coagulants/flocculants as a pre-treatment for water (deep wells and other sources).  This is followed by filtration through layers fo sand filters and disinfection by clorination to eliminate waterborne microorganisms.  These steps culminate with filtration using ITDI-developed ceramic filters, which are very effective in trapping any suspended particles.
