EDI Pure Water Treatment
The working principle of EDI ultra pure water treatment equipment: The electrodeionization (EDI) system mainly uses a direct current electric field to make the ions in the water medium move in a directional manner through a separator, and uses the selective permeation effect of exchange membranes to purify water quality as a scientific water treatment technology. In an electrodialysis machine, there are usually multiple sets of alternating negative membranes, positive membranes, and separators (a, B) between a pair of electrodes, forming a concentration chamber and a dilution chamber (i.e. cations can pass through the positive membrane and anions can pass through the negative membrane). The cations in the dilution chamber water migrate towards the negative electrode and pass through the positive electrode membrane, which intercepts them in the concentration chamber; Anions in water migrate towards the positive electrode through the negative electrode membrane and are intercepted by the positive electrode membrane in the concentration chamber. As a result, the number of ions in the water through the dilution chamber gradually decreases and becomes freshwater. On the contrary, the water in the concentration chamber, due to the continuous inflow of negative and positive ions in the concentration chamber, increases the concentration of dielectric ions and becomes concentrated water, achieving the purpose of desalination, purification, concentration or refining.
Advantages of EDI ultra pure water treatment equipment:
1. No need for acid-base regeneration: In a mixed bed, the resin requires the use of chemical reagents for acid-base regeneration, and EDI eliminates the treatment of these harmful substances and heavy work. Protected the environment.
2. Continuous and simple operation: In a mixed bed, the operation process becomes complex due to each regeneration and water quality change. However, the water production process of EDI is stable and continuous, and the water quality is constant. There are no complex operating procedures, greatly simplifying the operation.
3. Reduced installation requirements: Compared to mixed beds with the same treatment water volume, the EDI system has a smaller volume. Adopting a modular structure, flexible construction can be carried out according to the height and humidity of the site. Modular design makes EDI easy to maintain in production work.
Ozone sterilization and ultra pure water treatment
The disinfection principle of ozone (O3) is that the molecular structure of ozone is unstable at room temperature and pressure, and it will rapidly decompose into oxygen (O2) and a single oxygen atom (O) on its own; The latter has strong activity and has a strong oxidizing effect on bacteria, killing them. Excess oxygen atoms will combine on their own to form ordinary oxygen atoms (O2), without any toxic residues, hence they are called pollution-free disinfectants. It not only has strong killing ability against various bacteria (including hepatitis virus, Escherichia coli, Pseudomonas aeruginosa, and miscellaneous bacteria), but also is effective against fungal toxins.
The sterilization mechanism and process of ozone belong to biochemical processes, which oxidize and decompose the glucose oxidase necessary for the oxidation of glucose within bacteria.
2. Interact directly with bacteria and viruses, destroy their organelles and ribonucleic acids, decompose macromolecular polymers such as DNA, RNA, proteins, lipids, and polysaccharides, and disrupt the metabolic production and reproductive processes of bacteria.
3. Penetrating the cell membrane tissue, invading the cell membrane, acting on outer membrane lipoproteins and internal lipopolysaccharides, causing distortion of cell permeability, leading to cell lysis and death. And dissolve and denature the genetic genes, parasitic strains, parasitic virus particles, bacteriophages, mycoplasma, and pyrogens (bacterial viral metabolites, endotoxins) within dead bacteria.
