Reverse osmosis mainly uses the permeation principle of a semi-permeable membrane to apply a pressure to it in a certain way. The force opposite to the natural permeation direction makes the water in the concentrated solution penetrate into the dilute solution. This method is called reverse osmosis. The device composed of reverse osmosis elements is a reverse osmosis device. Applied to pure water in electronics, medicine, food and other industries; purification and preparation of water for textiles and chemical industries; purification and preparation of water for food and beverage and brewing process water; concentration and recovery of useful substances in aqueous solutions in industrial production; power plants, etc. Pre-desalination treatment of make-up water for high-pressure boilers of enterprises; desalination of brackish water and seawater; as a first-level desalination equipment for high-purity water production.
Process characteristics of pure water prepared by two-stage reverse osmosis:
Suitable for areas with low salt content in raw water
Low total carbon content (organic matter) in water production
Pollution-free emissions
The structure is relatively simple
Purified water preparation process:
Pre-treatment + RO1 + RO2
Optional disinfection methods: activated carbon pasteurization, CIP cleaning system, distribution system ozone sterilization, distribution system pasteurization, distribution system pure steam sterilization.
Remarks: The water system system is customized according to user requirements (URS)

Can choose 304 or 316L material, and use professional equipment and equipment to strictly inspect the quality;
Modular 3D design, construction according to drawings;
The pipeline connection method uses welding first, followed by clamp connection to control the growth of microorganisms;
Using orbital automatic welding machine, 20% endoscope inspection after welding, 100% endoscope inspection after manual welding;

Online monitoring of the water quality meets customer needs; The system minimizes the risk of microbial growth, and the dead angle is smaller than the 3D requirement; The drainage adopts the air blocking method to avoid back suction and cross-contamination, and set the lowest point of discharge and a slope of 5‰; The flow rate of the return water in the circulation pipeline is greater than 1m/s to control the growth of microorganisms; The secondary concentrated water, EDI concentrated water, and unqualified purified water are returned to the original water tank for reasonable reuse, saving raw water consumption and reducing later operating costs.

Has three levels of management authority, followed by operator, administrator, and senior administrator. Each login account has a corresponding login password (the password can be modified), and the system will automatically log out after 5 minutes; prevent unauthorized personnel from entering the system from misoperation, and the parameters can be restored to factory settings; Set up overload, high voltage, and low voltage protection in key places of the system, and automatically record all faults and alarm systems; Multi-party internal communication system, at any level of the work site, can view the operating status of each other; When the system fails, the other party will be notified by SMS, and the mobile phone can be realized to observe the operation status.
