Activated Carbon Water Filter Bacteria

Charcoal filters or carbon filters are a common method of water filtration.

Activated carbon water filter bacteria.

Carbon filters are easy to install and maintain and operating costs are usually limited to filter replacement. Performance depends upon the amount and the type of carbon the way the filter is designed and the residence time of the water. Carbon blocks in general work better than gac granular activated carbon filters though many of the latter can do a fine job. An activated carbon filter clears water of organic compounds that make your water taste or smell bad.

Activated carbon also called activated charcoal activated coal or active carbon is a very useful adsorbent. It is so cavernous in fact that just one gram of activated carbon can easily have a surface area of 500m2 or higher. Contaminants adhere to the surface of a carbon filter and only clean water flows to your house. Some perform much better than others and some are designed for selected special purposes.

Activated carbon filters are recommended for water without bacteria present. When bacteria colonize a water filter they produce a slimy biofilm which reduces the activated carbon s adsorptive capacity so it filters the water less effectively producing unpleasant tastes and odors. Activated carbon filters are small pieces of carbon typically in granular or powdered block form that have been treated to be extremely porous. Adsorption adheres particles to a surface like a piece of velcro.

Depending on the type and concentration of the contaminant being removed some carbon filters may require special hazardous waste handling and disposal. Gac filters contain loose millimeter sized granules of activated carbon that can detect and filter contaminants that would often go undetected in some other types of filters. Activated carbon filters are able to achieve this by the process of adsorption thanks to their. Carbon filters remove contaminants through adsorption.

They come in various types. A carbon filter can remove organics affecting the taste odor and color of your water and reduce some undesirable chemicals such as chlorine and pesticides. Water sources can be contaminated by bacteria heavy metals and other contaminants. The filter media used in these filters are usually coconut shell coal wood and a few others with coconut shell carbon being the most renewable.
