Source of tap waterTap water is mainly drawn from rivers, lakes, groundwater, and surface water through the pumping station of the water plant. According to the survey, 82% of people drink water from shallow wells and rivers. The problem of river water pollution has always existed. Let’s take a look at these colorful water polluted by industrial wastewater. Because some companies secretly discharge into the river in order to save costs, the pollutants not only endanger the lives in the water, but also penetrate into us. The drinking water area threatens our drinking water health.
Relevant data shows that 75% of the water quality is seriously polluted by bacteria exceeding the standard, and there are about 160 million people whose daily drinking water is polluted. Therefore, our tap water is very likely to be polluted at the source.
treatment process of the water plant
The water source is polluted, but doesn't the tap water meet the relevant national standards? Relevant data shows that the current compliance rate of the city's public water supply factory water samples is only 83%, and 17% are unqualified. The unqualified tap water is related to the purifier treatment process of the water plant. Generally speaking, the water treatment process of waterworks can be divided into traditional treatment process and advanced treatment process.
Let's look at the traditional processing steps:
The first step is to extract the water source, from the rivers and lakes to pump the water to the water plant, and put in the flocculant.
The second step is the initial precipitation, this step is mainly to filter out the obvious impurities, weeds, and floating objects and sediments visible to the naked eye in the water.
In the third step of precipitation, coagulant is added to settle the sediment in the water.
In the fourth step of filtration, quartz sand is generally used for multi-layer water filter to thoroughly remove impurities in the water.
The fifth step is disinfection. Put a certain dose of chlorine dioxide into the water for disinfection. After disinfection, it enters the clean water tank. The above is the tap water that the water plant delivers to thousands of households.
When water treatment plants add silt, chlorine dioxide and other substances, it is difficult to guarantee that they will not remain after treatment. Sometimes, our tap water will turn yellow and there will be a layer of foam. These are the residues of disinfection.
Because advanced treatment processes require higher technology and cost, 98% of water plants are still using traditional treatment processes. Therefore, the water treated by the water plant is not necessarily clean.
There is still a long transportation process for tap water to enter thousands of households, and a large number of bacteria and parasites will be deposited in the pipes that transport tap water over time. In some places, the aging and corrosion of transmission and distribution pipelines, low leaks, and unstable water pressure have caused bacteria and microorganisms to accumulate and heavy metals exceeding the standard; in some communities, water tanks or water towers have not been cleaned for more than ten years. Algae grows over the entire water tank. Full of dirt and rust. It is difficult for everyone to notice these, but you can look at your faucet to see if there is a layer of yellowish scale. I don't know how many bacteria are in it.
Tap water can be said to be really "dirty". Even if the water is boiled, it cannot kill harmful substances such as heavy metals, nitrites, and organic pollutants. At present, the best solution is to get a water filter faucet.
