Send Inquiry1.Chemical Industry Reverse Osmosis Introduction
Reverse osmosis is a kind of membrane separation technology. It mainly uses the permeation principle of semi permeable membrane to exert a kind of pressure on it in a certain way. The force in the direction of natural permeation makes the water in the concentrated solution permeate into the dilute solution. This way is called reverse osmosis. The device composed of the elements of reverse osmosis is called reverse osmosis device.

4.Working principle of Chemical Industry Reverse Osmosis
Reverse Osmosis generally includes pretreatment system, reverse osmosis device, post-processing system, cleaning system and electrical control system.
The pretreatment system usually includes raw water pump, dosing device, sand filter, activated carbon filter, precision filter and so on. Its main function is to reduce the pollution index of raw water and other impurities such as residual chlorine, so as to meet the requirements of reverse osmosis. The equipment configuration of the pretreatment system should be determined according to the specific conditions of raw water.
Reverse Osmosis Filter mainly includes multi-stage high pressure pump, reverse osmosis membrane element, diaphragm shell (pressure vessel), bracket and so on. Its main function is to remove impurities from the water and make the effluent meet the requirements.
The main reverse osmosis machine is mainly composed of booster pump, membrane shell, reverse osmosis membrane, control circuit and so on. It is the core part of the whole water treatment system, and the quality of water quality depends on this part most. As long as the model of membrane and booster pump are properly selected, the filtration capacity of RO main engine for salt in water can reach more than 99%, and the conductivity of effluent can be guaranteed within 10us / cm (25 ℃).
5.The typical process flow of modern ultra pure water manufacturing adopted by our company is as follows:
1). Pretreatment - reverse osmosis - purified water tank - ion exchanger - ultraviolet lamp - pure water pump - water point
2). Pretreatment - primary ro - Secondary ro (positive charge RO membrane) - purified water tank - pure water pump - UV lamp - water point
3).Pretreatment reverse osmosis intermediate water tank intermediate water pump EDI device purified water tank pure water pump UV lamp water point
4). Pretreatment → UV sterilization device → primary RO device → secondary RO device → intermediate water tank → EDI device → deoxidation device → nitrogen sealed pure water tank → TOC UV removal device → polishing mixed bed → ultrafiltration device → the water quality at the water point meets the ASTM standard of the United States and the ultra pure water quality standard of the Ministry of Electronics (grade 4: 18m Ω * cm, 15m Ω * cm, 2m Ω * cm and 0.5m Ω * cm)
6.Design principles
Quality: according to the water quality requirements and production characteristics of ultra pure water required by the customers, and considering the water quality of the water source (the customers are required to provide the water quality analysis report or source water sample).
Expandability - the system is designed and planned in sections. Considering the needs of nearby water and production safety, the capacity can be expanded at any time according to the needs of the production line, and customers can invest in stages.
Note: the development and application of reverse osmosis and EDI technology are the professional direction and specialty of our company.
