Mechanical filth in the water (mud, sand, insects, leaves…)
Residual chlor (public water supply, well and tank chloring i itd...)
Water hardness
Mechanical filtration
MECHANICAL FILTRATION means physical occlusion of mechanical filth in the water, and it takes place on the surface of special filter cartridge. With such a filtration only those particles can be occluded that are bigger than the pores of the filter material on the filter cartridge.
Contingent upon the type of the mechanical filth in the water (mud, sand, leaves…) the porosity and size of the filter cartridge is determined.
This filter is the best solution for the household appliance, the water filtering for the protection of valves, faucets, boilers and installations.
Residual chlor
RESIDUAL CHLOR it appears in the water during the water chlorinating before distributing it through the aqueduct grid, for the purpose of maintaining the microbiological integrity of the drinking water. Chlor is added more than necessary in order to maintain sanitary integrity of the water until it reaches the consumer – residual chlor. Residual chlor can affect the organoleptic qualities of the water (taste, smell) and in reaction with some organic compounds constructs compounds that are not desirable for human usage.
Deodorization of the water means the improvement of the water quality i.e. removing the substances from the water which can cause a bad smell, taste, color… Nowadays we use filters with activated carbon for dechlorization and deodorization.
MICROBILOGICAL WATER INVALIDITY mostly occurs in ground waters (springs, wells) by inadequately done captures, climatic factors, as well as during the mix with fecal waters. Very important factor that affects the microbiological water invalidity is the proximity of objects for keeping the livestock, proximity of cultivated area overlaid with fertilizer, as well as the polluted areas of exploited water. Even if the water at the exploited area is microbiologically valid it can be contaminated during the transport through the aqueduct grid (corrosion, air pockets).
There are many ways of water disinfection. Most applied and economical are:
Water chlorinating could be done:
Discontinuously – by adding natriumhypochloride directly into the well (capture) in the determined procedure,
UV sterilization is done by UV lamps that are in the casings made of quartz glass and have limited life span. Water disinfected by the UV lamp must be impeccably clean regarding its color and mechanical filth in it. The sterilization process itself occurs as the water in thin laying gets over the cylindrical quartz casing in which is the UV lamp. Influence of the UV spectrum at the microorganisms is instantly.
Microbiological filter cartridges– Filter cartridge is made of a special material that allows cartridge washing and disinfection up to 50 times. Simple install and efficient disinfection, as well as long life span, places these cartridges at the very top of the appliance in the household water disinfection.
Water hardness - In addition to microbiological defect, water hardness is the most frequent emergence in households that uses their own wells and captures. Water hardness is due to the presence of Ca and Mg in the water. The appearance of the lime scale is due to the high content of Ca and Mg carbonates and sulfates. We use several ways to remove the lime scale:
Softening by using ion exchange resin – Water preparation by the procedure of ion exchange is always done where there is whole or part water softening needed.
Magnets - In contrast to softening, they do not change the mineralogical configuration of the water but influence the chemical bond and prevent lime scale from appearing.
