Reverse osmosis pure water equipment process

Reverse osmosis pure water equipment is a reverse osmosis membrane that relies on pressure to force water molecules to selectively permeate water molecules, that is, the principle of reverse osmosis water purification. This device is a reverse osmosis device. The osmotic pressure can be separated, extracted, purified and concentrated by a reverse osmosis method which is greater than the osmotic pressure. It can remove more than 98% of dissolved salts in water and more than 99% of colloids, microorganisms, particulates and organic matter, and become the preferred equipment for modern pure water and space water (ultra-pure water) projects.

Reverse osmosis technology is a modern high-tech developed in China in recent years. Reverse osmosis is the application of a pressure greater than the osmotic pressure to the solution, allowing water to separate from the solution through a special semi-permeable membrane. Because this process is contrary to the phenomenon of infiltration, it is called reverse osmosis. According to the different osmotic pressure of various materials, a reverse osmosis method larger than the osmotic pressure can be used for a certain solution to achieve the purpose of separating, extracting, purifying and concentrating the solution. The reverse osmosis device mainly separates the ion range in the solution, it does not require heating, and has no phase change process, so it has lower energy consumption than the conventional method. The reverse osmosis device is small in size, simple in operation, and has a wide application range. The use of reverse osmosis equipment to treat industrial water, does not consume a lot of acid and alkali, no secondary pollution, and its operating costs are relatively low. Reverse osmosis membrane separation technology, referred to as RO technology.

The reverse osmosis equipment system uses different processes depending on the source water quality. After the tap water is treated by the first-stage reverse osmosis equipment system, the conductivity of the produced water is <10μS/cm, and the conductivity of the produced water after the second-stage reverse osmosis equipment system is <2μS/cm or lower, and the ions are supplemented by the reverse osmosis equipment system. The exchange equipment or the EDI equipment can prepare ultrapure water to a resistivity of 18 megaohms (conductivity = 1 / resistivity).
