Water is vital for human survival. It serves the following functions to the human body namely making up water lost via breathing, perspiration, digestion and urination, regulating body temperature, transporting nutrients to body cells, removing waste from the body and protecting organs, tissues and joints. We need to re-hydrate by drinking water and other beverages. RO Plant price in Pakistan
The main sources of drinking water are rivers, lakes, reservoirs, ground water and the sea. The water from these sources at times could not be consumed right away. It needs to go through water treatment processes before we could consume it. The reason is that it could be contaminated with pollutants like suspended solids, algae, bacteria and viruses.
Water goes through different processes like screening, rapid mixing, sedimentation, flotation, filtration, micro-screening, disinfection, de-chlorination etc. in the treatment plant. After these processes, suspended solids, micro-organisms and bacteria are eliminated according to the required specification. The end result is water that is safe for drinking purposes.
Before we are able to drink water from the treatment plant, it has to be delivered to our houses and offices. During the delivery through the pipe line from the treatment plant or its storage area, the drinking water may be contaminated again with mud and suspended solids due to pipe leakage and repair works, heavy metals from pipe corrosion as well as bacteria and viruses originated from dirty storage tank.
Hence, when the water comes out from the tap, it may be still contaminated with suspended solids, bacteria, viruses and heavy metals like lead and iron which could affect adversely our body.
How to get good quality drinking water?
It is advisable to treat the water from the tap one more time before consumption.
Most of us choose to boil it. Boiling can kill the bacteria. However, it can activate the chemical reaction between chlorine and other pollutants. The more often you boil the tap water, the more intoxicated it becomes.
An advisable way to treat the tap water is to use a water filter or purifier to screen the pollutants before consumption. A good water filter could screen almost 100% of the suspended solids, minerals, bacteria and viruses. The end result is pure water containing no suspended solids, bacteria, viruses and minerals. It could be consumed at the ambient temperature, cooled or heated before drinking. It tastes good and refreshing. Even you boil it, it will not get intoxicated. Therefore, water filter produces good quality drinking water.
