Why water smells of chlorine?
on March 22 mankind the next time celebrate the day of water. We live on the planet which three quarters are covered with water. On its Earth, as they say, though be filled in. And, nevertheless, there is not enough water. There is no pure, fresh water, and, first of all, for drink.
Not less than one billion people drink dirty water worldwide, and more than three million earthlings, generally children, annually die from - for the diseases connected with bad water. It transfers 80% of diseases of the person. These are data of World Health Organization.
Paradox. At water treatment stations, water meets standards. But... in process of its advance to the consumer, the chlorine entered for water disinfection is spent. Here - that also begins so-called “ secondary pollution “.
Pipelines on which water gets to our houses are mostly unsuitable. They rusted long ago, both inside, and outside. Metal of which pipes are made gets to water, on walls of pipes slime is formed of hydroxides of metals, in this excellent dirt bacteria are got. In turn, bacteria strengthen corrosion, in metal fistulas are formed. Here can already get to water anything.
Passing multikilometer labyrinths of pipes, water stands, in it the microflora inevitably appears. Water finds brown color, a smell and smack of decay. The use of such water does not promote health and longevity.
Should increase concentration of chlorine in water. It is better to drink water with chlorine, than with live pathogenic microbes. Chlorine - it is bad, but it is necessary.
Water is chlorinated, and chlorinated worldwide for a long time. It is the most reliable way of disinfection of water not so much at station how many in pipes. Ozonization or radiation of water so far exotic.
The state, in any case our state - around the world cannot cope with this problem centrally so far. Exit, however, is. Water should be finished cleaning closer to the consumer.
How to eliminate a chlorine smell? It is enough to leave the container with water open at several o`clock - chlorine will disappear. Even quicker chlorine will come out if to boil water.
However from chlorination in water the poisonous and causing cancer organochlorine connections, dioxine are formed, and boiling does not relieve of them.
There is nevertheless a means allowing to clean from water both surplus of chlorine, and organic chemistry. It is sorption (absorption) of harmful impurity household filters.
There are many types of household filters. There are free-flow filters (water in them is filtered by drift) and pressure head (they are put on the crane or cut in a pipe). They are distinguished on extent of cleaning, by a filtration method, on productivity and on cartridge capacity.
Taking into account that on average the person consumes in food during a day of about 3 liters of water, if to take with a stock, you need the filter with a productivity up to 5 l a day on each family member.
Filters with absorbent carbon are most popular. Coal absorbs various substances from water just as it works in a gas mask. Coal filters equally willingly absorb both organic, and inorganic substances: chlorine, pesticides and herbicides, heavy metals.
However be careful! Bacteria perfectly breed in the filter. If long not to change a cartridge in the filter, water from it will become gryazneenefiltrovanny. Sometimes coal is covered with silver, but silver does not kill microorganisms, and only interferes with their reproduction.
More perfect are the filters working by the principle “ return osmosis “. But it is already other history.
In order that it is correct to choose the filter, it is the best of all to address the expert. Happens that the filter chosen independently is not suitable for your water. It depends on variations of composition of water, the weighed particles, bacterial impurity.
Correctly picked up filter will keep your kidneys and a liver from harmful substances and bacteria. The cheap household filters acquired without appropriate consultation - only for properties. Penny-wise and pound-foolish.
