CHOOSING A SUITABLE WATER PURIFIER :
METHODS OF PURIFICATION OF WATER :
1 – Boiling. Boiling water is the cheapest and safest method of water purification.
2 – Filtration. Filtration is one of the effective ways of purifying water and when using the right multimedia filters it's effective in ridding water of the compounds.
3 – Distillation.
4 – Chlorination.
The first method alone is exclusively for domestic . Rest look for large scale , for community , city and so on .
THE TYPE OF PURIFIERS AVAILABLE IN THE MARKET :
RO (Reverse Osmosis). In RO water purifier, it passes water through the pump to increase water pressure then pass that pressured water through RO membrane(semi permeable). During this process dissolved solids and TDS present in water are eliminated. RO water purifier converts hard water to soft water.
THE DISADVANTAGE OF RO WATER PURIFIER IS IT PRODUCE A LOT OF WASTE WATER.
UV water purifier uses UV radiations to kill contaminants, microorganisms. Treating water passes through the UV radiation source tube and exposes water to UV radiation. UV water purifier is advisable to use with soft water which has contaminants.
UF (Ultra filtration). UF water purifier contain hollow fiber threaded membrane. UF removes dispersed material, suspended solids, and other large molecular weight materials from water which are harmful to human health. UF water purifiers are works without electricity.
TDS (Total dissolved solids). Minerals, salts or dissolved metals such as calcium, chloride, nitrate, iron , sulfur and some organic matter that dissolved in water commonly referred as TDS. TDS expressed in terms in milligrams (mg) per liter of water, also referred in parts per million (ppm). Presence of TDS in water will affect the water taste. If you are not sure of the water hardness you can test it with the small devise called TDS meter. TDS value of 500 mg/l water is considered as very hard. Most commonly used purification systems to reduce TDS are carbon filter and reverse osmosis(RO). - What Mr. Kaushikk mentioned in his post
AS WE ARE TALKING ABOUT WATER PURIFICATION AT HOME ONE HAS TO KNOW WHAT SORT OF WATER IS SUPPLIED . DON’T GO BY THE BROCHURE BY THE BROCHURE BY THE COMPANY . IT IS LIKE GOING TO A QUACK FOR TREATING PNEUMONIA . more
You are correct - but Common is not so common and everybody does not use it more
We should try to make use of that more often.......
Sales gimmicks are full of enticements and luring you to succumb.....
Common sense means using the faculties that dear God has bestowed upon us by birth......You can never go wrong that way..... more
Faculties . If humans misuse or ignore there is natural
punishment . They become vestigial . Already we see
that in a very very important field , medical profession .
The acumen slowly going vestigial as the dependance is
more on Lab Investigation .
We only have to keep in mind the tall claims by
commercial profit mongering companies and select
judiciously . If we haven't being doing it at least train
the next gen. more
