Reverse osmosis is an emerging water treatment technology. Large-scale water purification equipment enhances water purity through a reverse osmosis main unit, removing impurities from the water. It involves developing a membrane separation technology powered by pressure differences. As this technology has evolved, we have also started researching reverse osmosis, and now produce various types of reverse osmosis equipment. When pure water and saltwater are separated by an ideal semipermeable membrane, which only allows water to pass through while blocking salt, water on the pure side of the membrane will spontaneously flow through the semipermeable membrane into the saltwater side, a phenomenon known as osmosis. If pressure is applied to the saltwater side of the membrane, the spontaneous flow of water is suppressed and slows down. When the applied pressure reaches a certain value, the net flow of water through the membrane is zero, and this pressure is called the osmotic pressure. When the pressure applied to the saltwater side of the membrane exceeds the osmotic pressure, the direction of water flow reverses, and water from the saltwater side flows into the pure water side. This is the basic principle of water reverse osmosis (RO) treatment.

Application Scope

Large reverse osmosis equipment is widely used in the oil, chemical, metallurgy, papermaking, power, construction, and enterprises and institutions requiring high water quality for purification. It is also suitable for the food, dairy, and airport industries.
