Currently, the active carbon is made from plant carbon-rich organic matter such as wood or derivatives (bark, wood waste, coconut shells, peanut shells, olive pits, or coal, peat, lignite, petroleum residues).
Manufacture of active carbon in two stages
Pyrolysis (carbonization or calcination) at high temperature of the selected materials.
Activation of absorbency air thermal shock second pyrolysis until thousand degrees and water vapor to remove tars that clog pores or phosphoric acid until five hundred degrees if you want larger pores.
Activated carbon is a lot in the water treatment under certain conditions!
It is unquestionably effective for purifying water. However it is essential to comply with some rules if we want to exploit its qualities to the maximum and safe.
Rule number 1
The water should have a low turbidity, that is to say, it is clear, regardless of its source or place of settling.
Rule number 2
The water must be pre-filtered, preferably in two stages, for example in a first filter sleeve 25 micron filter and then in a second filter with filter sleeve 5 microns. For larger flow rates there is a 1 micron filter sleeve manufactured by Airwatec for its industrial filters Cintropur.
Rule number 3
The activated carbon filter is always placed last when the rules 1 and 2 are met.
Rule number 4
Buy activated carbon from a dealer who buys from a manufacturer that meets all health and environmental production constraints. Attention many false activated carbon are sold at very low prices. Do not get any illusions, they are very poor or even dangerous! It's like getting a perfectly inactive drug that should cure you of disease, in vain ...
Do not gamble with your health, activated carbon Cintropur for example, is made in Europe and benefits from all the certifications strict control. Below 10 euros a liter retail price incl, quality activated carbon is probably suspect.
Note that the water purifier with activated carbon with silver proposed by Cartis is good provided they meet the first three rules described above. For their part, the Ministry of Health of the Netherlands has banned the use of activated carbon with silver. Indeed, the use of compounds of silver is highly controversial in the scientific community believes that silver is a heavy metal that can not be eliminated by the human or animal body.
Important: a filter with active carbon is not a water softener and will not reduce the hardness of the water.
Rule number 5
he sleeve or sleeves and activated carbon filters should be changed every six months. It is a fact that has been studied by the Research and Development department Airwatec for thirty years and scientifically validated. The bells of the filters must also be thoroughly cleaned, disinfected and rinsed. These are sanitary precautions that will protect you from any bacterial infection, viral or micro organic.
Rule number 6
If you drink filtered water from a supply other than the public network, it is essential to control a physical and chemical analysis according to the current settings and updated to assess the most suitable treatment system. According to the bacteriological composition of water, a more specific treatment is placed at the water supply before distribution into drains.
Last tip before use activated carbon or active carbon
If you have any doubts as to its real value, establish a specification that lists all the negative parameters of the water to be treated. Indeed, it may be that activated carbon filtration will be useless or totally inadequate, referring to the recent concerns of the European Union on drug residues.
