Literally: "De-infecting" = "preventing contagion". In the parlance "free of microorganisms make".
In the parlance "free of microorganisms make". The literal language is lost. According to the German Pharmacopoeia (DAB) means disinfection: enable "dead or living material in a state, that it can not infect "
Sterilisation: process, be freed by the subjects of microorganisms. with sterilization, refers to sterilization and disinfection process, by the materials and articles of live microorganisms including their dormant stages (for example spores) be freed. The thus achieved state of materials and articles are called "sterile".
Time to reduce by 90%: The Dezimalreduktionszeit is the time, in the 90% die of a population. Is the time required, die in the nine-tenths of the population, the population is thus reduced to a tenth, as Dezimalreduktionszeit D (D value).
KBE / CFU: Colony forming unit, colony forming unit. A colony forming unit (CFU or CFU, englisch colony forming unit, CFU) is a parameter, which plays a role in the quantification of microorganisms, namely when the viable cell count of microorganisms in a material is determined culturally.
disinfecting process. The history of mankind is the history of disinfection. Immediately after discovery of fire, the fire was used, boil water to. The high temperatures kill harmful organisms in the water and made the water for people available.
Chlorine is a chemical element with the symbol Cl and atomic number 17. In the periodic table of the elements it is in the 7. main group and heard so together with fluorine, Bromine, Iodine and astatine to the group of halogens. Elemental chlorine is under normal conditions in the form of a diatomic molecule Cl2 gaseous form.
The dosage of liquefied chlorine gas from pressurized containers is widely used in water treatment plants, which have a high consumption of free chlorine.
Checklist Chlorgas plants. The planning and implementation of a chlorine gas system requires the collaboration of various trades. The requirements concerning architectural areas, electric ranges, the water treatment plant, water supply, safety technology, fire protection and much more. From experience, a summary of the requirements of the insurance companies should be led.
The dosage of liquid sodium hypochlorite NaClO purchased is frequently used in smaller water treatment plants, which have a low consumption of free chlorine.
The dosage of solid calcium hypochlorite Ca(ClO)2 it's easier … because it contains a higher proportion of free chlorine and does not disintegrate under favorable conditions. Calcium hypochlorite is the calcium salt of hypochlorous acid with the chemical formula Ca(OCl)2. After the gaseous and liquid products, the first solid chloro-product is treated here. Calcium hypochlorite Ca(ClO)2 according to DIN EN 900 is commercially available as an chlorine preparation in the form of tablets or granules. Roof DIN it contains at least 65 % Chlorine.
