Water is free for everyone. It is the gift of nature. From the beginning of the earth, water is with us. The earth is covered by 71 percent of water. But nowadays we have to pay for it because of the quantity of fresh water.
Day by day pollution increases, water gets polluted. I am unable to explain the importance of water in a post. The chemical waste of industry, acid rain, plastic waste pollutes our freshwater. This polluted water is harmful for us. As per an American blog, nearly 3.4 billion people losses their life because of water-related problems. But we are able to purify the water towards making best-purified water.
Water purifying technology:
When I am a child, my mother boils water to purify it. But technology changes now you can enjoy the purest form of water.You may listen about four these basic types of water filter technology RO, UV, UF.
RO Water purifying technology:
RO stands for Reverse Osmosis. In this technology, it uses a semipermeable membrane of very small pores having diameter 0.0001-micron meter. It prevents all impurities from water. At first water filters in the first tank then the filtered water passes by the semipermeable membrane by having very high pressure. At last, we get the pure freshwater. This is the latest technology of water filter.
UV water purifying technology:
UV water purification is a method of purifying water by ultraviolet radiation. It kills 99% germs, bacteria of the water. It is also called e boiling method. It has a simple concept. It contains a small cylindrical pipe. Inside that pipe there are two holes one is to entertain water and other is to leave out water. When water passes through the pipe Ultraviolet light are used to kill germs, bacteria but it can not filter the hazards thing from water.
UF water purifying technology:
UF process is a not a modern process .it stands for Ultra Filtration. It has a membrane of size 0.01-micron meter. It only filters all colloidal particles from the water.
A similar concept is in the Micro-Filtration or MF process. It has pores of size 0.1 micron. It can only filter the bacteria. So it is not useful.
But there are some rural areas where they don't use these processes but they have no complaint against water. This is all about TDS ( total dissolving Solids). TDS represents the total concentration of dissolved solvents in the form of ppm. Water having low TDS or less than 350 ppm is safe to drink. In that rural areas the TDS value is low so it is less harmful.
