Water is an essential element in our daily life, an adult's daily drinking water is about 2500ml, so water safety is also more and more people pay attention to.Life is rich, people in order to improve the quality of life, live in high-rise buildings, but the appearance of the magnificent housing, but hidden under the deadly threat.
The human body has sixty trillion cells, all living in the fluid, fluid clean cells on the clean, fluid is not clean, people will grow this or that; most people in modern society only care about the safety of food, but ignored the most critical element of life - ‘water’ quality.
There are many sources of tap water pollution, the largest source of pollution from the secondary water supply.
If you are living in high-rise housing, every day when you open the tap at home, are you clear, the tap out of the water is actually not directly supplied by the water company, but through the community's secondary water supply equipment set up in the building at the top of the cistern after the water pressurisation before sending your home.
Hazardous substances in tap water
Heavy metal ions
including rust, sediment, platinum, mercury, road, etc., often drink heavy metals in the water suction easy to cause human bone pain, dementia, stones and other diseases.
Pathogenic microorganisms
Drinking water with excessive bacteria can easily cause cholera, hepatitis A, colds, SARS, avian influenza, infectious diseases and so on.
Organic chemicals
Organic chemicals such as fertilisers, pesticides and residual ammonia in tap water are very likely to cause mutations in human cells, tumours, malformations and other diseases.
Environmental Hormones
specifically refers to the pollution of certain scientifically identified endocrine disruptors, commonly known as contraceptive pills in tap water", which can lead to reduced immunity, affect fertility, damage the nervous system, and may even cause cancer.
[The cause of secondary water supply]
Due to the rapid development of high-rise buildings in the city, municipal water supply network pressure is insufficient, the water distribution network is too wide, the water plant does not have enough pressure and storage capacity to transport water to each place, so the location of the higher places to establish a cistern or storage tank, water from the water plant out, first flow to the set in the roof of the cistern or storage tank, and then through the water mains to your home.
[The dangers of secondary water supply]
Most of China's urban water supply system is not like the developed countries, not a pipe directly to the residents' homes, but the water into the community after the storage to the pool or tank, and then pressurised, and then sub-pipes to the residents.
The community pools are not cleaned, disinfected or covered and locked for many years, rainwater and foreign objects into the tank, sediment accumulation, harmful algae breeding. Dead rats, broken items, rust and peeling rustproof paint skin, insects and ants floating in the carcasses and other conditions often appear.
The pool has not been cleaned for 10 years, the secondary water supply is difficult to rest assured
Is your neighbourhood a direct water supply or a secondary water supply? Cell cistern how often cleaned, there is no water quality test report?
Tap water turbidity causes most of the secondary water supply links
With more and more high-rise buildings in the district, drinking water basically through the ‘water plant → municipal pipe network → secondary water supply facilities → users’ several links. Due to the secondary water supply facilities and more contact with the outside world, if the management is not in place, sealing is not strict, not regular cleaning and disinfection, it is easy to cause secondary pollution.
City water company responsible person told reporters: ‘The public found some turbidity in the tap water will be to the water plant complaints, but from the cases we deal with, most of the problems in the secondary water supply link.’
Secondary pollution of the tap water distribution network
Tap water factory, after a long water distribution network and high-rise water towers, water tanks and other facilities to increase the number of pollutants, such as rust, dirt, bacteria, etc., they interact to generate a number of toxic and carcinogenic substances, and therefore very unsafe for direct use.
How to avoid tap water pollution?
1, you can carry out regular cleaning of the water storage tower on the roof of the building, such as cleaning frequency once every three months, residents can take turns to maintain the water tower to ensure that there are no cockroaches, rats, bugs and other insects crawling inside the water tower.
2, if the family uses the iron water pipe, then it is recommended to replace the PPR pipe, which can effectively prevent the breeding of moss and microorganisms.
3、Before going to bed at night, fill a large bucket of water for sedimentation; the next morning colloid, rust, sediment and other specific gravity greater than the water of the dirt will be sunk in the bottom of the water, the water will appear very clean.
4, early in the morning to brush your teeth, put some salt or vinegar inside the water, which is conducive to the killing of bacteria. 5, the residents of the community jointly with the property owners to carry out water pipeline network renovation, the implementation of the whole community purification.
Installation of terminal purification equipment
Of course, to drink safe water, to the family installed a water purifier is the most convenient and safe way. Water purifier is the depth of water purification treatment of small water treatment equipment, its main function is to filter the floating water, heavy metals, bacteria, viruses and other harmful substances are removed, the effect is obvious.
Moreover, the water purifier is not only applicable to areas where tap water is more seriously polluted, but also filters residual chlorine in regular tap water, and also improves the taste of drinking water, which improves your quality of life while safeguarding your health.
