1. What is a water softener?
Li Zong, general manager of Shijiazhuang Bi Haubert Environmental Protection Engineering Co., Ltd., a designated enterprise in in addition to formaldehyde, Shijiazhuang, replied: The water softener, as its name implies, softens water and is a device for removing water and alkali. It uses the principle of ion exchange, and the removal rate of hardness (water and alkali) is over 99%, without replacing the filter element. All the water used by the whole family can be softened, connected in series to the main pipe behind the water meter and installed in the kitchen cabinet or at the location designated by the user.
2. General Manager Li of Shijiazhuang Bi Haubert Environmental Protection Engineering Co., Ltd., a designated enterprise in in addition to formaldehyde, Shijiazhuang City, explained the function of water softener:
Water equipment (wall-hung boiler, radiator, water heater, solar energy, etc.). ) it will never be blocked by scaling, and its service life will be longer, so as to eliminate the potential safety hazard and equipment loss caused by scaling. Bathroom facilities (glass bathroom, mirror, bathtub, toilet, etc. ) Using soft water, there will be no white stains and rust spots that are difficult to clean. Moreover, ladies often take a bath with soft water, which has a good cosmetic effect. We can save a lot of energy and trouble in life.
3, working principle and daily operating costs:
The water softener is provided with a water inlet and a water outlet at the position of the control head. Connect the water inlet behind the water meter to the main water outlet, so that all the water flowing out is softened water and all the domestic water is solved. The jar of the water softener is filled with resin and transparent yellow particles. The water softener relies on this resin to adsorb calcium and magnesium ions in water. When the resin reaches a certain saturation, the adsorption function of the resin is restored by replacing calcium and magnesium ions in water with concentrated brine (this is called regeneration). Regeneration needs non-iodized salt. There is no waste water during normal operation, and the monthly salt fee is about 10 yuan. The automatic water softener consumes up to 3 degrees of electricity a month.
4. Types of water softeners:
According to the appearance, it can be divided into integral type and split type. According to the controller used, it can be divided into semi-automatic and fully automatic. Automatic water softener is divided into time type and flow type. The automatic water softener is completely controlled by the computer control head, and it runs automatically without special personnel.
5, water softener function:
It is mainly softened water, which can remove water and alkali, and can't be drunk directly. It belongs to domestic water, such as bathing and beauty. Water softener can't drive away impurities, bacteria, viruses and heavy metals in water, but its function is to drive away water and alkali.
What is a pure water machine
1, the benefits of pure water machine:
Pure water machine is a miniaturization of pure water plant, which uses tap water as water source and purifies pure water through reverse osmosis water treatment technology. Household pure water machine is small and exquisite, generally installed in the kitchen, and equipped with a special faucet for pure water. Besides drinking, it can also solve the problem of water consumption such as cooking, which is not only very convenient, but also relatively cheap. After installing the pure water machine, you don't need to buy bottled water, and it doesn't affect the water dispenser at home. Heating or cooling the purified water produced by pure water machine can also reflect its original value!
2, the working principle of pure water machine:
The technical core of water purifier is reverse osmosis membrane. Its working principle is to exert a certain pressure on water, so that water molecules and ionic mineral elements pass through a reverse osmosis membrane, while most inorganic salts (including heavy metals), organic substances, bacteria, viruses, etc. dissolved in water. Can not pass through the reverse osmosis membrane, thus strictly separating pure water from impermeable concentrated water. The pore size of reverse osmosis membrane is only 0.000 1-0.00 1 micron, which is equivalent to one millionth of a hair. The smallest viruses are also above 0.2 microns, so they cannot penetrate the reverse osmosis membrane.
3, the category of pure water machine:
According to the usage, it can be divided into manual (or economical) and automatic. The difference is only in the backwashing of the water purifier. The economical water purifier uses a manual backwashing valve.
4, the characteristics of pure water machine:
There is a booster pump, a power supply and a water storage tank, which are generally five-stage filtration. The first stage is filter element, the second and third stages are activated carbon, the fourth stage is RO reverse osmosis membrane for aerospace technology (this is the core), and the fifth stage is refined activated carbon, which is mainly used to improve the taste. In the fifth stage, a medical stone filter element can also be placed to become a mineral drinking water purifier.
5, the function of pure water machine:
Not only can it drive away impurities, rust, sediment, colloid, bacteria and viruses, but it can also drive away radioactive particles, organic substances, fluorescent substances and pesticides that are harmful to human body, and it can also drive away annoying soda and heavy metals, so as to ensure that there is no soda when you boil water, and at the same time ensure that your family drinks healthily.
6. Disadvantages of water purifier:
The water purifier mainly produces wastewater in the process of making water. The pore size of RO reverse osmosis membrane of water purifier is very small, so the small one must be forced to pass through by pressure, and impurities that cannot pass through RO membrane will be poked out, resulting in waste water. However, this kind of wastewater can be reused, such as flushing toilets and washing mops.
What is a water purifier?
1, classification of water purifier
There are also many types of water purifiers, which are divided into coarse filter water purifiers according to the number of filter elements used: PP fiber cotton and activated carbon are generally used, and there are first-class filter element water purifiers, second-class filter element water purifiers, third-class filter element water purifiers, fourth-class filter element water purifiers and fifth-class filter element water purifiers. At the same time, according to the different central technologies used, it is also divided into coarse filter, hollow fiber precision filter and ceramic filter core precision filter.
2. Functions and disadvantages of the water purifier;
According to the different filter elements, the water purifier can filter out impurities, rust, some bacteria, viruses, colloids and so on. In tap water, but it has little effect on heavy metals and soda. Some water purifiers simply cannot drive away heavy metals and soda. So the water purifier can meet some requirements of users, but it still can't achieve the purpose of direct drinking. It's best to boil before drinking. If you only have a water purifier at home, you can replace the tertiary activated carbon with a resin core, which can remove water and alkali, but after a while, you have to remove the resin core and soak it in salt water for regeneration.
3. Advantages of water purifier:
Safe to drink, retain most minerals in raw water, no waste water and no electricity.
4. General Manager Li of Shijiazhuang Bi Haubert Environmental Protection Engineering Co., Ltd., a designated enterprise in in addition to formaldehyde, Shijiazhuang City, explained the characteristics of the water purifier:
There is no motor, no power supply, and filtration is driven by water pressure. There is no water storage tank, so it is better to use five-stage filtration. The first stage is PP fiber filter, the second and third stages are activated carbon, the fourth stage is hollow fiber membrane or ceramic filtration, and the fifth stage is post-activated carbon, which is mainly used to improve the taste.
