why is ceramic filter candle used in water purification equipment
The candles are made of several layers through which the water must pass. Layer 1 is made from clay which is fired to attain a fine pore structure. The size of these pores can differ, which means the candles can have varying success filtering different particles. The second layer is impregnated with colloidal silver, which deactivates bacteria, on the inside and outside. Layer 3 is activated carbon, which has huge potential to adsorb any particles that are able to pass through the other layers. Contaminants such as iron, chlorine, and those giving odd odour or colour, slide into the holes of the carbon honeycomb and hold fast. Ceramic Filter Candles can take many forms. They can be long and thin with a rounded top, or shorter and wider with a flat top.
A ceramic filter is a device used to filter water. The small pore size of the ceramic material filters dirt, debris, and bacteria from the water. Diatomaceous earth, or clay, is a type of sedimentary rock that is composed of very fine particles that usually makes up this type of filter. The purpose of these filters is to provide clean drinking water that is bacteriologically safe.
The most basic type of ceramic filter is in the form of Pottery These vessels are made from a mixture of clay and a combustible material such as sawdust. The ceramic filter pot is formed and fired, burning out the combustibles and leaving fine porous holes in the filter. The unit is then treated with Collodial silver , a liquid suspension of microscopic silver particles. The silver acts as an antiseptic and disinfectant in the water purification process.
