Why use a two-stage reverse osmosis equipment to produce urea for vehicles?
- 2019-05-18-

Perhaps the more common water treatment equipment is the reverse osmosis equipment and the two-stage reverse osmosis equipment . Reverse osmosis (RO) is a reverse osmosis migration movement. It is a pressure driven method for separating solute and solvent by selectively trapping a semipermeable membrane. It has a pore size of about 5-10a and is commonly used for purification and concentration of various liquids. A more common application example is the water treatment process. Reverse osmosis technology is used to remove inorganic ions, bacteria, viruses, organic matter, colloids and other impurities in raw water to obtain excellent pure water.

The reverse osmosis technology guarantees the quality of the effluent of the two-stage reverse osmosis equipment and meets the needs of different industries. The water quality is very stable and the water quality is very reliable. Reverse osmosis technology is a more efficient and energy-saving membrane separation technology in the world today. The utility model has the advantages of novel technology, simple operation, low running cost, green energy saving, convenient maintenance and the like. The use of high pressure pumping and maintaining a reverse osmosis membrane can effectively remove solid solutes in water. Organic substances, colloids, microorganisms, bacteria and other impurities. It has the advantages of wide application range, strong initiative, small floor space, low energy consumption and good effluent quality.

The two-stage reverse osmosis unit consists of a two-stage reverse osmosis unit, a cleaning system and an intermediate water tank. The two-stage reverse osmosis process effectively removes ions from the water. At the same time, the effluent meets the requirements of subsequent EDI equipment. Ultrapure water can be prepared with a resistivity of up to 18m/cm.

So back to the title, why do we use two-stage reverse osmosis equipment to produce automotive urea?

The vehicle urea is a 32.5% aqueous urea solution and an ultrapure water solvent. The raw material is a raw material for supplying urea and ultrapure water for vehicles. In other words, the production of urea for vehicles that meets Chinese standards requires the use of ultrapure water. Therefore, only two-stage reverse osmosis equipment equipped with EDI equipment can produce ultrapure water with a resistivity (>18 M/cm) and then produce qualified vehicle urea.
