Purification principle of integrated water purifier

Compared with other water purification equipment, the integrated water purification device process has low cost and is very suitable for purification of domestic water. Its main disadvantage is that it has no removal of heavy metals and organic pollutants.

The integrated water purification process requires a booster pump, power, and pressure. The main disadvantage is that there is more wastewater. Generally, about 50% of the wastewater needs to be filtered. The purification cost is high, and the water production is low. It can only solve the problem of drinking water.

In addition, during the activation process, some oxygen-containing functional groups are formed on the amorphous portion of the activated carbon surface, which enables the activated carbon to have properties of chemical adsorption, catalytic oxidation and reduction, and can effectively remove some metal ions in water.

Should also pay attention to continue to provide good water to the cells, and strive to create a fresh and healthy living environment for the cells. The structure of domestic water purifiers includes rough filtration, activated carbon adsorption, ion exchange resin, hollow fiber and reverse OS. Mosis membrane: Consider an ideal and practical water purifier from the following aspects: Replace the water purifier mainly by simple filtration such as activated carbon, ceramics, etc. The pore diameter of the dual-control membrane ceramic filter that is easy to breed bacteria is smaller than the pore diameter of bacteria It can completely isolate bacteria from the filter, but water can pass through and retain beneficial minerals and trace elements in the water. At the same time, there is no secondary pollution in the process of using the water purifier. Function, the disadvantage is that the filter element has a short life and a small amount of water.

Water softener: Water softener can soften the water quality, reduce the hardness of the water, and then reduce the generation of scale. The general soft water method is to replace the calcium and magnesium ions in the water with a regenerated sodium resin, but it cannot purify the water or remove the water. Various harmful pollutants.

The basic principle of purchasing a water purifier is to remove visible pollutants in the water, such as rust, colloidal substances, odors, residual chlorine and some by-products, organic pollutants, heavy metals, etc., and retain the mineral elements in the water. According to the water quality in different regions , Choose the right water purifier. Uh.

Due to the excellent performance of the composite sintered activated carbon rod, the integrated water purification process can be directly used for high-demand filtration such as drinking and cooking. These products can also integrate medical folding bacterial membranes.

Therefore, diseases, bacteria, heavy metals, solid soluble substances, polluted organics, calcium and magnesium ions cannot pass through the reverse osmosis membrane at all, thereby achieving the purpose of softening and purifying water.

Microfiltration is a type of microporous membrane made of cellulose or polymer materials. It uses its uniform pore size to trap particles, bacteria, colloids, etc. in the water, making it unable to pass through filtration.

Principle of ultrafiltration: Ultrafiltration is a pressurized membrane separation technology, that is, under a certain pressure, small molecule solutes and solvents pass through a special membrane with a certain pore size, so that macromolecular solutes cannot pass through and stay on the membrane side, so that macromolecular substances can Partial purification, ultrafiltration is also a principle of the membrane separation process. Ultrafiltration micropores are less than 0.01 microns, which can completely remove harmful substances such as bacteria, rust, colloids, and retain the original microporous membranes between .001-0.02 microns in water. According to the different film materials, it is divided into inorganic film and organic film. Inorganic films are mainly ceramic films and metal films.

The purification of turbid tap water in urban and rural areas should use domestic water purifiers with both coarse and fine functions. It has serious pollution to the water quality. It requires complete removal of impurities in the water and direct drinking without heating. Reverse osmosis water purifiers should be used. Pure cotton filter element water purifier: That is, a single-cylinder water purifier is equipped with various polypropylene cotton filter elements. Generally, the price of the machine is low, but the filter element is easily clogged, the replacement frequency is high, and the filtration accuracy is not high. This is only used for water? Composite sintered activated carbon water purifier: The main filter medium is activated carbon rods. Activated carbon rods are usually made by burning activated carbon powder and bonding materials with different particle sizes at high temperatures.

Features: Due to the porous structure of the activated carbon powder (estimated that the specific surface area of 3-5g of activated carbon powder is equivalent to the size of a standard American football field), the burned activated carbon rod is very compact.
