Single-stage reverse osmosis equipment, also known as reverse osmosis equipment, is the raw water through the pretreatment system, filter, through the high-pressure pump to send the raw water to the reverse osmosis device to directly produce product water, called single-stage reverse osmosis, is only a one-stage reverse osmosis device of reverse osmosis filtration equipment, its specifications will be smaller than the conventional reverse osmosis equipment.
Single-stage reverse osmosis equipment application industry:
1. Preparation of pure water and ultrapure water in electronics, industry, food and other industries, light textiles and chemical industries.
2. Purification and preparation water for industrial process water/chemical circulating water, chemical product manufacturing, etc.;
3. Water purification and preparation of water for food and beverage industry, drinking pure water, beverages, beer, liquor, health care products, etc.;
4. Useful substances and concentration and recovery of aqueous solutions in industrial production;
5. Preparation of high-pressure boiler make-up water for boilers in the power industry, thermal power generation boilers, medium and low-pressure boiler power systems in factories and mines, etc.
Features of single-stage reverse osmosis equipment:
1. The degree of automation is high, and the pretreatment system is also automated, which can realize unmanned operation and save labor costs;
2. Single-stage reverse osmosis equipment has few components, short process, high production efficiency, low noise, stable and reliable;
3. Single-stage reverse osmosis equipment can monitor and control water quality online, monitor water quality changes in real time, and ensure water quality safety to a large extent;
4. The personalized design in line with the local water quality can more appropriately meet the water production needs of customers.
The difference between single-stage reverse osmosis and two-stage reverse osmosis:
First of all, in terms of appearance, there is a vertical pump on the top of the single-stage reverse osmosis equipment, and two vertical pumps on the side of the double-stage reverse osmosis equipment.
In addition, the desalination rate of single reverse osmosis equipment and two-stage reverse osmosis equipment is somewhat different, and the desalination rate of double reverse osmosis equipment is higher than that of single-stage reverse osmosis equipment.
The difference in the system is that the single-stage reverse osmosis equipment is a device that removes some substances from the water through a permeable membrane separation technology.
Double reverse osmosis equipment refers to the filtration of raw water through two RO reverse osmosis membranes to achieve a higher desalination rate standard. When the quality of raw water is close to that of tap water, the technology of two-stage reverse osmosis can make the conductivity value of water reach 10μs/cm. When the general industry or other industries do not have too high requirements for water quality, they will generally use single-stage reverse osmosis equipment, and if they have strict requirements for water quality, they will choose to use double-stage reverse osmosis equipment.
