The TCM (Tirta Cupumanik) ceramic filter provides potable water from nearly any raw water source, such as shallow wells, deep wells, piped water and ponds. The filter eliminates as much as 99.88% bacteria, and to some extent reduces iron and manganese contents in the water. The TCM ceramic filter cannot treat saline/brackish water or colored water or water that contains heavy/hazardous metals. A pretreatment process will be needed for this water before treating it with the ceramic filter.
The filter is made from locally available materials, such as clay and risk husks. Proper mixture of clay powder, fine rice husks and water is pressed to form a pot and then fired in a kiln at temperatures over 800 degrees Celsius to produce a low fired ceramic pot. A silver nitrate solution is applied to prevent the growth of viruses and bacteria in the water. TCM ceramic filter is produced by Yayasan Tirta Indonesia Mandiri, a non-profit organization with its mission to provide access of potable water to the people of Indonesia.
In Indonesia, about 50 million poor people in urban and rural areas do not have access to piped water. Most of them depend on unsafe water for drinking. Ceramic water filters are suitable for providing quality drinking water at the household level.
