Ceramic and Activated Carbon Filters

Water filtration is a process which separates all the impurities from the water purifying it completely. Household water purifying system mostly uses ceramic and activated carbon filters as they are easy to maintain and less expensive. However, the working mechanism of the two filters is slightly different but they follow the same principle for purifying the water.

Ceramic Water Filters

  • These water filters are usually divided into two components and they are





  • Filters can generally be two types and they are candle and pot. Candles are most commonly used filters used by most of the water purifying systems.
  • The receptacle is fitted along with a tap and these ceramic materials are mounted on top of it.
  • When water is poured the filters block all the impurities except for the water molecules making it pure.
  • The impurities which get accumulated in and around the filter region needs to be cleared or removed periodically as it may lead to the growth of micro-organisms and algae.
  • Use a soft brush and a soap solution in order to clean this ceramic water filter. you can also use colloidal silver in order to prevent the growth of algae and bacteria.
  • MSR Miniworks

    are portable ceramic filters which requires manual pumping for filtration of water.

  • Drinking water from the household plumbing can be purified with the help of in-line filters.
  • The main disadvantage of these filters is that they do not remove the chemical properties and are prone to cracking and chipping off.

Activated Carbon Filters

  • Charcoal is generally used for these filters and the active carbon is usually made up of coconut shell, wood, bituminous coal and lignite.
  • 1 gram of active carbon may cover around 2.17 times of a tennis court.
  • This filter has the capability of removing

    0.5 to 50 mm sized impurities

    from the water successfully.

  • Absorption is the chemical mechanism used by the active carbon filters that helps in purifying the impurities.
  • These filters usually show



    hydrophobic filters

    and they help in absorbing all the chemicals and oils to the filters.

  • Granular activated filters

    and powdered block filters are the two types of activated carbon filters.

  • Block filters has the capability of filtering large impurities from the water.
  • These filters can also be used for municipal water treatment plants and for reversing osmosis systems in it’s pre-treatment stages.
  • The growth of bacteria in these filters can be restricted by using





The main disadvantage of using these filters is that they cannot filter the dissolved salts or impurities and they cannot be used for high quality purification.
