Common technology in Water treatment field

1) Ozone regenerator sterilization

The disinfection principle of ozone (O3) is: the molecular structure of ozone is unstable at normal temperature and normal pressure, and it will quickly decompose into oxygen (O2) and a single oxygen atom (O); the latter has strong activity and is extremely harmful to bacteria. Strong oxidation, kill it, and the excess oxygen atoms will recombine into ordinary oxygen atoms (O2) without any toxic residues, so it is called a non-polluting disinfectant. It is not only effective against various bacteria (including hepatitis Viruses, Escherichia coli, Pseudomonas aeruginosa and miscellaneous bacteria, etc.) have a strong ability to kill, and are also very effective against cidamicin.

- The sterilization mechanism and process of ozone belongs to the biochemical process, which oxidizes and decomposes the glucose oxidase necessary for the oxidation of glucose inside the bacteria.

- Directly interact with bacteria and viruses, destroy their organelles and ribonucleic acid, decompose macromolecular polymers such as DNA, RNA, proteins, lipids and polysaccharides, and destroy the metabolic production and reproduction process of bacteria.

- Penetrate the cell membrane tissue, invade the cell membrane and act on the lipoprotein of the outer membrane and the lipopolysaccharide inside, causing the cells to be permeable and deformed, resulting in cell lysis and death. And the genetic genes, parasitic bacteria, parasitic virus particles, bacteriophage, mycoplasma and pyrogens (bacterial virus metabolites, endotoxins) in the dead bacteria are dissolved, denatured and destroyed.

2) Activated carbon filter adsorption

Activated carbon relies on adsorption and filtration to mainly remove organic impurities such as color, odor, residual chlorine, and residual disinfection in water.

3) Ion exchange filter purification

The principle of the ion exchange method is to exchange the anions and cations of inorganic salts in water, such as calcium ions Ca2+, magnesium ions Mg2+, sulfate SO42-, nitrate NO3-, etc., with ion exchange resins to make the anions and cations in water and resin Anion and cation phase exchange, so that the water is purified.

4) Reverse osmosis system purification

It is a material separation process in which pure water is extracted from water containing various inorganic substances, organic substances, and microorganisms, using pressure as the driving force, using the selectivity of reverse osmosis membranes that can only permeate water but not solutes. The pore size of the reverse osmosis membrane is less than 10 angstroms (1 angstrom is equal to 10-10 meters), and it has a strong screening effect. Its desalination rate is as high as 99%, and the sterilization rate is greater than 99.5%. It can remove inorganic salts, sugars, amino acids, bacteria, viruses and other impurities in water.
