Water purifier
1. Classification of water purifier
There are also many types of water purifiers. According to the number of filter cartridges, the filter is divided into coarse filter water purifiers: PP fiber cotton and activated carbon are generally used, and there is a first-stage filter water purifier, a second-stage filter water purifier, and a three-stage filter water purifier. Four-stage filter water purifier and five-stage filter water purifier. At the same time, according to the central technology used, it is also divided into coarse filtration, hollow fiber precision filtration and ceramic filter precision filtration. It mainly depends on what kind of filter element is used.
2. The functions and disadvantages of the water purifier;
According to different filter elements, the water purifier can filter out impurities, rust, some bacteria, viruses, colloids, etc. in tap water, but the effect on heavy metals and water alkali is not great, and some water purifiers cannot remove heavy metals and water at all. Alkali. So the water purifier can meet some of the user's requirements, but still does not achieve the purpose of direct drinking, it is best to drink after boiling. If there is only a water purifier at home, you can replace the third-grade activated carbon with a resin core, so that you can remove the water-alkali, but after a period of time, you have to remove the resin core and soak it in salt water to regenerate it.
3, the advantages of water purifier:
Safe drinking, retain most of the mineral quality in raw water, no waste water, no electricity.
4, the characteristics of the water purifier:
There is no motor, no power supply, and the water pressure drives the filter. There is no water storage tank, preferably five-stage filtration, the first stage is PP fiber filter, the second and third stage are activated carbon, the fourth stage is hollow fiber membrane or ceramic filtration, the fifth stage is post-activated activated carbon, mainly Used to improve the taste.
Water Softener
1. What is a water softener?
A: As the name suggests, the soft water machine softens the water. It is a water-alkali removal device. It uses the ion exchange principle to remove the hardness (water-alkali) by more than 99% without replacing the filter element. All water for the whole family can be softened completely, connected in series on the main pipe behind the water meter, installed in the kitchen cabinet or at the user-specified location.
2. What is the role of the water softener?
Water equipment (wall-hung boiler, radiator, water heater, solar energy, etc.) will never scale and block, and the service life will be longer, and the safety hazard and equipment loss caused by scale will be eliminated. Bathroom facilities (glass bath room, mirror surface, bathtub, toilet) Etc.) With soft water, there are no white spots and rust spots that are difficult to clean, and ladies have a good cosmetic effect in soft water bathing. We can save a lot of energy and trouble in our lives.
3. Working principle and daily operating expenses:
The water softener has a water inlet and a water outlet at the position of the control head. Connect the water inlet to the back of the water meter and the total water outlet. In this way, the water that flows out is all softened water, and all domestic water is solved. The soft water tank is filled with resin and transparent yellow particles. The water softener relies on this resin to adsorb the calcium ions in the water. When the resin reaches a certain saturation, the calcium and magnesium ions in the water are replaced by concentrated brine to restore the adsorption function of the resin (this is called regeneration). It is necessary to have no iodized salt. When there is no waste water in normal operation, the monthly salt money costs about 10 yuan. The fully automatic soft water machine consumes up to 3 degrees in one month.
4. Categories of water softeners:
According to the appearance, it can be divided into whole and split. According to the controller used, it can be divided into semi-automatic and fully automatic. Fully automatic is divided into time type and flow type. The automatic water softener is completely controlled by the computer control head, fully automatic operation, no need for special operation.
5, water softener function:
Mainly to soften water, remove water and alkali in water, can not be directly consumed, belonging to domestic water, such as bathing, beauty and so on. The water softener cannot remove impurities, bacteria, viruses and heavy metals from the water. Its function is to drive out the water alkali.
Pure water machine
1, the benefits of pure water machine:
The pure water machine is the miniaturization of the pure water plant. The tap water is used as the water source, and the pure water is purified by the reverse osmosis water treatment technology. The household water purifier is exquisitely compact and generally installed in the kitchen, and is equipped with a special tap for pure water, in addition to drinking, It can solve the problem of water use such as cooking, which is not only convenient but also cheaper. After installing the pure water machine, it is no longer necessary to buy bottled water. It does not affect the water dispenser at home. It can also reflect its original value to heat or cool the pure water made by the pure water machine!
2, the working principle of pure water machine:
The core of the pure water machine is the reverse osmosis membrane. Its working principle is to exert a certain pressure on the water, so that the water molecules and the ionic mineral elements pass through a reverse osmosis membrane, and most of the inorganic salts dissolved in the water. (including heavy metals) organic matter and bacteria, viruses, etc. can not pass through the reverse osmosis membrane, so that the pure water and the impervious concentrated water are strictly separated, and the pore diameter on the reverse osmosis membrane is only 0.0001--0.001 micrometer, which is equivalent to one. One millionth of the root hair. The smallest size virus is also above 0.2 microns, so they are not transparent to the reverse osmosis membrane.
3, the category of pure water machine:
According to the use situation, it can be divided into manual type (also economical type) and automatic type. The difference is only in the backwashing aspect of pure water machine. The economical pure water machine uses manual backwashing valve.
4, the characteristics of pure water machine:
There are booster pumps, power supplies, water storage tanks, generally five-stage filtration, the first stage is the filter element, the second and third stages are activated carbon, and the fourth stage is the RO reverse osmosis membrane for aerospace technology (this is Core), the fifth level is refined activated carbon, mainly used to improve the taste. It is also possible to place the fifth grade of the stone filter to become a mineral drinking water machine.
5, the function of pure water machine:
It can not only remove impurities, rust, sediment, colloids, bacteria, viruses, but also remove radioactive particles, organic substances, fluorescent substances, pesticides harmful to the human body, and also drive off the annoying water alkali and heavy metals to ensure You don't have water and alkali when boiling water, and you can keep your family healthy.
6, the shortcomings of pure water machine:
The pure water machine will produce primary wastewater in the process of water production. The RO reverse osmosis membrane of the pure water machine has a particularly small pore size. The small water must be driven by pressure, and the impurities of the RO membrane are poked out. Waste water is also produced, but this water can be reused, such as flushing the mop.
