It is obvious that most of the things we use in our daily life- air, water, food- are all polluted and impure atleast to a small extent. Now we have a technique to purify almost anything using highly porous carbon particles. They are called Activated Carbon Filter. The key factor which gives carbon these properties is the large surface area of the activated carbon. It can adsorb things to a suprisingly large extent.
These activated carbon filters are produced by complicated chemical processes. There are many types of them namely Powdered Activated Carbon, Granular Activated Carbon, Extruded Activated Carbon.etc. These are all used for different purposes. PAC is mainly used for purification of air by removing unwanted odor and vapor. These are often found as small packets in tinned and canned containers. They remove toxic materials and gases from the atmosphere surrounding them and keep it fresh and pure.
GAC is also mainly used in the purification of water and air. Extruded activated carbon is in the form of long cylinders consisting of powdered activated carbon and a binder. Another type of activated carbon filter is the polymer-coated. It is mainly used in the purification of human blood. The technical name of this process is ‘hemoperfusion’. In this method, a patient’s blood is made to pass through a specially designed activated carbon filter. The filter removes all the toxic materials from the patient’s blood. This is one of the significant medical application of activated carbon filter.
Nowadays carbon filters are used to purify almost anything and has become our life-purifier. New technologies are being developed to further extend the application of activated carbon filters.

and smell associated with algae blossoms.

There have been numerous cases where a water supply has been so-called “contaminated” with a increasingly large reproduction of algae. The use of activated carbon filters helps to thoroughly clean the water during the osmosis process. Making the water much more drinkable to its’ consumers. The quality of the water can be greatly diminished by the rapid growth of algae. There are no scientific studies that can link the algae to any severe outbreaks of contamination, however it has been known to kill fish and cause a serious reaction to patrons that have prolonged exposure to its toxin.

The implementation of using the activated carbon water treatment will rid the water of any decontaminations by absorbing them. The carbon is a highly absorbent element and actually grabs the free radicals and such that are released by the algae. Thus, improving the quality of water while also making it also safer for the environment.

The activated carbon absorption is the most commonly used remedy for the taste and smell dilemmas of most water sources in the United States. There are many other preventative and repair methods for the cleaning and improving water quality, however this is the easiest, but not the simplest. It is easier to hook up a pump and a hose to create and oxidation system, than it is to accurately measure out the exact amount of the carbon needed to purify the water without damaging its’ natural ecosystem. The activated carbon is the revolutionary way to keep are water supplies safe and healthy.

PFOA LEVELS - ACTIVATED CARBON FILTER

The Sapphire Group, based in Washington, is known for its health related studies all over the world. They conduct studies and report on prevailing pollutants in the atmosphere or water and alerting the powers that be, so that they may carry out the remedial measures to ensure human welfare as also of flora and fauna around the world. The latest study by the company revealed that the concentration of PFOA (perfluorooctanoic acid) found in drinking water was quite safe and was not hazardous to health. The concentration currently found in the drinking water was far below the danger mark and did not pose to be a threat to human life, animals and plants. Even the workers who were exposed to this chemical in their work place did not suffer from any health problems, as per the report submitted by the Group.

The Group also thankfully revealed that the PFOA levels in water was decreasing at a regular pace owing to the precautions taken by the manufacturing companies in reducing their emission in atmosphere, which are capable of polluting drinking water. Any traces of PFOA in water can be effectively removed with the help of activated carbon in water filters for domestic and commercial purposes. The activated carbon in the filter adsorbs the chemical and renders the water safe for human consumption. The human body too, is not known to retain PFOA in the system. The role of activated carbon filters is useful in remaining such chemicals which could otherwise prove hazardous to human health.
