Water purification equipment, what types are available?

Substandard water on the human body, there are visible and invisible harm.

Visible is usually microbial contamination hazards, may cause sudden acute illnesses, the good thing is that people are accustomed to drinking water, can kill microbial contaminants, this harm is not obvious.
Invisible hazards, easy to be ignored but more attention, the total amount of organic compounds in tap water exceeds the standard easy to lead to chronic diseases.
Drinking water with excessive total organic compounds, no problem for a day or two days, half a year to see the problem, but organic compounds will be enriched in the human body, and ultimately harmful to the body, and in serious cases, may cause cancer, teratogenic, mutagenic.
With the increasing prominence of domestic water pollution in recent years, people began to focus more on high-quality living conditions and a healthier living environment, water purification equipment can effectively remove water pollutants, impurities, coliform viruses, heavy metals and other harmful substances.
For the growing demand for water purification equipment at the same time, the consumer demand for water purification products is also gradually improving, using the core technology, the real effect of water purification, brand trust and other factors, is becoming the core of consumer concern.
So what are the categories of water purification equipment?


 First, the pre-filter
Pre-filter is the first coarse filtration equipment for the whole house water, can filter tap water in the sediment, rust, eggs, red worms and other large particles.

Pre-filter is generally installed in the front of the pipeline, so the word “pre” to name; and “filtration”, refers to the basic principle of this type of equipment.
Main function: Filter municipal water supply secondary pollution, including rust, sediment and algae, the first gateway to water purification at home.
Advantages: to protect the water-related equipment and piping at home, such as all faucets, water pipes, water heaters, etc.; low initial investment, maintenance of almost zero cost.
Disadvantages: coarse filtration, limited by the filtration precision, unable to filter smaller particles of suspended solids, can not achieve the effect of direct drinking.
Suitable for people: most families are worth buying.

Second, the central water purifier
Central water purifier is a large domestic water treatment equipment, originated in 1832, suitable for whole-house central water purification, its core technology is mainly microfiltration (PP fiber cotton and activated carbon), ultrafiltration (hollow fiber), KDF, ACF, ceramic cartridges and so on.

Main functions: removal of large particles of suspended solids, residual chlorine, odor; deep protection of pipes, water-related appliances, internal piping, high-grade sanitary ware.
Advantages: higher filtration precision than the pre-filter, deeper filtration; larger filtration capacity, generally 0.5 to 1.5 tons / hour.
Disadvantages: more expensive, larger volume, need to have a special space reserved.
Suitable for the crowd: the people who have very high requirements for the quality of life water; there are many pieces of high-grade water-related equipment such as water softeners, dishwashers, boilers, smart toilets, etc.; larger household areas such as villas, houses.

Third, direct drinking machine (RO reverse osmosis water purifier)
Drinking water machine is the municipal raw water filtration and purification treatment (physical method) to produce water purification machine for direct human drinking water, also known as terminal water purification equipment.
With water quality in line with the “drinking water” (GB5749-2006) municipal tap water as raw water, through a variety of filtration and adsorption units, filtering out pollutants in the water, such as rust, colloidal substances, odors and tastes, residual chlorine and some disinfection by-products, organic pollutants, heavy metals, and so on, to produce water for direct drinking.
Main function: High-precision multiple filtration, direct drinking.
Advantages: the highest precision filtration equipment for home use, small size, easy to install, RO reverse osmosis membrane for direct drinking.
Disadvantages: the water output is relatively small, but can meet the family drinking water.
Suitable for the crowd: ordinary family standard.

Fourth, sub-quality water supply fixed-point centralized water supply, unified cycle of water supply, triggering the third human drinking water revolution!

Pipeline drinking water is “pipeline high-quality direct drinking water” for short, it is the way of quality water supply, in residential areas, hotels, office buildings, schools, hospitals, etc. within the water purification station, the use of modern high-tech biochemical and physical technology, the depth of purification of tap water, remove organic matter, bacteria, viruses and other harmful substances in the water, retain trace elements that are beneficial to the human body. It removes organic matter, bacteria, viruses and other harmful substances from the water, and retains trace elements and minerals that are beneficial to the human body; at the same time, it adopts high-quality pipes to set up an independent circulating pipeline network, and sends the purified high-quality water to the users for people to drink directly.

Main function: High-precision multiple filtration, direct drinking.
Advantages: does not occupy living space, centralized treatment, unified maintenance, safe and fresh, healthy and environmentally friendly, no waste water, low cost.
Disadvantages: need to be centrally installed
Suitable places: living quarters, hotels, office buildings, schools, hospitals, tourist attractions, parks, etc.
