Introduction to the principle of bottled pure water production line equipment

Pure water is generally multi-filtered, so the pure water in the market is still relatively reassuring. As the name suggests, microbial indicators are timely observation of the content of microorganisms in pure water, including pathogenic bacteria, yeast, E. coli, etc. This is because the initial processing of the raw water to the packaging transporter, for some reasons, will cause bacterial contamination of the water. The conductivity of the bottled pure water production line equipment is the characteristic index of pure water, reflecting the purity of pure water and the control of the production process. However, for pure water, purity is the basic requirement of Zui, and the metal elements and microorganisms are too high. Both will lead to high conductivity.

The bottled pure water production line equipment uses the selective permeability principle of the anion-cation exchange membrane, and its main component is an ion exchange membrane, which is divided into a positive membrane and a negative membrane. Under the action of the applied electric field, ions in the water migrate directionally, the cation moves toward the negative electrode, and the anion moves toward the positive electrode. When the ions reach the surface of the membrane, the ions in the fresh water side migrate to the thick state due to the selective permeability of the ion exchange membrane. In the water side, the concentrated water is drained to achieve the purpose of desalination and desalination. The energy of ion migration depends on the DC voltage supplied by the rectifier, and the device desalination rate is generally designed to be 80%-90%. The middle is blocked by a semi-permeable membrane, and the solvent in the dilute solution will naturally flow through the semi-permeable membrane to the concentrated solution side, and the liquid surface on the concentrated solution side will be higher than the liquid surface of the dilute solution to form a pressure difference to achieve penetration. In equilibrium, this pressure difference is the osmotic pressure.
