This is a common type of water filtration system, using the small pores found in natural ceramic material to effectively filter debris, bacteria and dirt out from the water supply. Diatomaceous earth, commonly known as clay, is a class of sedimentary rock, which is often porous. Ceramic water filters are normally made up of extremely fine particles that are used to filter the water and provide clean, safe drinking water, free from bacteria.

Pot ceramic water filters

These types of water filters are produced from a combination of clay and some form of combustible material, for example sawdust, which then undergoes a process which involves firing to eliminate the sawdust and leaving natural pores in the clay. The resulting porous clay is then treated using colloidal silver which serves the purpose of an antiseptic and disinfectant in the process of purifying water.

Any water which passes through the vessel holding the ceramic filter is free of bacteria and clean. While the actual process may seem slow, the costs associated with this type of filter are very low. Used across the world in many areas where water is not safe to drink and can cause problems for health, many agencies which work internationally are responsible for both producing and distributing these water filters as part of their plan to provide access to safe and clean drinking water.

Portable water filters

These systems are widely available and often used when camping and during other typical outdoor activities. Ceramic water filters can also be used to provide drinking water which is safe during emergency and disaster situations. There are some portable water filters which include pumps to make the process even quicker. The military and emergency response teams are among two of the largest users of this type of portable water filter and they are often employed in disaster scenarios when it is urgent that safe drinking water be available for populations, typically following events such as hurricanes, earthquakes and other similar natural disasters.

Ceramic candle water filters

These are formed using a cartridge system which is designed to accommodate a ceramic filter in the shape of a candle. These water filters are normally located in pressurized water pipes and are often found as part of a residential water supply system. Some filters designed to be used on the countertop and also under the sink are of the self sterilizing type which makes them easy to handle and keep clean. Replacement filter cartridges are widely available although often the cartridges can actually be easily cleaned and then used again. This provides a very cost effective method of water filtration.

How do ceramic water filters work?

Ceramic filter technology is capable of removing fine particles from water but at the same time does not change the oxygen and mineral content of the water, which results in clean, safe drinking water. The porous material used in the construction of ceramic water filters consists of silica-like sediment which results in contaminants being trapped and only clean, safe drinking water passing through the filter material. There are many applications for ceramic water filters, both industrial and commercial, and they are employed in manufacturing processes such as those to produce bottled water, wine, beer, and for beverage purification.

Because these systems produce pure water without changing the oxygen and minerals naturally contained in water, the future of such ceramic filter technology may be vitally important due to the existence of poor drinking water conditions in many areas.
