Activated Carbon Water Filter Bacteria

Activated carbon also called activated charcoal activated coal or active carbon is a very useful adsorbent.

Activated carbon water filter bacteria.

Charcoal filters or carbon filters are a common method of water filtration. Adsorption adheres particles to a surface like a piece of velcro. Some perform much better than others and some are designed for selected special purposes. Activated carbon filters are able to achieve this by the process of adsorption thanks to their.

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. Contaminants adhere to the surface of a carbon filter and only clean water flows to your house. Carbon filters remove contaminants through adsorption. Activated carbon filters are small pieces of carbon typically in granular or powdered block form that have been treated to be extremely porous.

Due to their high surface area pore structure micro meso and macro and high degree of surface reactivity activated carbon can be used to purify dechlorinate deodorize and decolorize both liquid and vapor applications. 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. Very often the components of a filtration system in a water cooler refrigerator or in line filter are difficult to access.

Carbon blocks in general work better than gac granular activated carbon filters though many of the latter can do a fine job. Depending on the type and concentration of the contaminant being removed some carbon filters may require special hazardous waste handling and disposal. 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. An activated carbon filter clears water of organic compounds that make your water taste or smell bad.

Performance depends upon the amount and the type of carbon the way the filter is designed and the residence time of the water. 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. Activated carbon filters found in air purifiers or air conditioning air filters are best suited to trap particles less than 0 3 micrometers in size such as tobacco smoke cooking oil fumes bacteria viruses and volatile organic compounds vocs.
