Pure Water System

1. Pure water（pure water equipment）Also known as purified water, it refers to water that meets the hygiene standards for drinking water and is sealed in a container using electrodialysis, ion exchange, reverse osmosis, distillation, and other appropriate processing methods. It is colorless, transparent, and directly drinkable. The space water and distilled water sold in the market are all pure water. The strong and weak electrolytes (such as SiO2, CO2, etc.) in the raw water are removed or reduced to a certain extent Its conductivity is generally 1.0-0.1 μ s/cm, resistivity (25 ℃) (1.0-10.0) M Ω * cm, and salt content is<1mg/L.

2. Ultra pure water is a type of water that further removes almost all conductive media from water, as well as non dissociative colloidal substances, gases, and organic compounds to a very low level. The resistivity is greater than 18M Ω* cm or close to the limit value of 18.25M Ω* cm. Ultra pure water is difficult to achieve in general processes. Two or more technologies from microfiltration, ultrafiltration, reverse osmosis, EDI, and ion exchange can be used to produce ultra pure water with a resistivity of up to 18.20M Ω* cm through reasonable process design and equipment selection

3. There are many differences between pure water and ultrapure water, which can be summarized as follows: A has different conductivity, with pure water having a conductivity between 2-10 US/cm and ultrapure water having a conductivity of 0.056 US/cm; The difficulty level of B manufacturing varies. Currently, the pure water used in the market is basically produced through methods such as reverse osmosis and distillation, while ultrapure water is produced through a series of complex purification techniques such as photooxidation, precision treatment, and polishing on the basis of pure water; The indicators of heavy metals, bacteria, and particle count are also quite different. The impurity content in pure water is in the ppm level, while in ultrapure water it is in the ppb level. Simply put, there are no impurities in ultrapure water, which is close to theoretical water; The fields of use for D are also different; E has different requirements for the material of the conveying pipeline, and ultrapure water has much stricter requirements for the material of the conveying pipeline than ultrapure water.

Main component functions:

1. Function of the raw water tank: It stores the raw water of the system, regulates the inflow, and also has a certain sedimentation effect on impurities in the inflow
2. Function of sand filter: Preliminary removal of sediment, impurities, suspended solids, and other particles in water to reduce turbidity.
3. Function of carbon filter: Utilizing the adsorption principle of carbon to adsorb discoloration, odor, residual chlorine, etc. in water.
4. Function of security filter: prevent large particles and impurities from entering the reverse osmosis membrane, causing damage to the membrane and protecting the reverse osmosis membrane.
5. Function of reverse osmosis host: It mainly achieves the purpose of producing purified water through reverse osmosis filtration.
6. Function of UV sterilizer: Kill residual bacteria in water and ensure effluent quality
