What is reverse osmosis equipment?

Separate the pure water from the solution containing a certain solute with a Semipermeable membrane that can only pass through water. At this moment, the water on the pure water side will spontaneously pass through the Semipermeable membrane and enter the solution side. The water surface on the solution side will rise. This phenomenon is called soaking. When the liquid level rises to a certain height, the pressure at both ends of the membrane reaches equilibrium, and the liquid level on the solution side no longer rises. At this point, there is a pressure difference between the two ends of the membrane, called the saturation pressure. Assuming that a pressure greater than the immersion pressure is applied to the solution side, the water molecules in the single stage reverse osmosis pure water equipment solution will be squeezed onto the pure water side, which is exactly the opposite process of immersion. We call it reverse immersion (reverse immersion). We can see from the process of reverse osmosis that due to the effect of pressure, water molecules in the solution enter pure water, increasing the amount of pure water, while the solution itself is concentrated. The reverse osmosis membrane used in this device is a semi permeable spiral coiled membrane. When the raw water is sent to the reverse osmosis membrane under a certain pressure, the water passes through the small pores on the membrane and is collected to obtain pure water. Impurities such as soluble solids, organic matter, colloidal substances, and bacteria in the water are intercepted by the reverse osmosis membrane, concentrated in the intercepted liquid and removed. Primary reverse osmosis can remove over 97% of dissolved solids, over 99% of organic matter and colloids, and almost 100% of bacteria from raw water.

RO equipment is one of the more advanced equipment in the international water treatment equipment for producing pure water. RO equipment has low operating costs, economy, convenient operation, and reliable operation. RO equipment is the equipment chosen by pure water treatment equipment manufacturers for producing pure water. This equipment is a first level reverse osmosis system, with a water production capacity of 15T/Hr. The production capacity of the equipment is based on the value of raw water at 25 ℃ and standard production conditions. Changes in water temperature and production conditions will affect the production capability of the equipment.

Generally, internationally advanced reverse osmosis technology principles are used for planning, and advanced membrane skills are utilized. Using 15 reverse osmosis membranes from Heidergy in the United States, pure water treatment equipment manufacturers form a primary reverse osmosis (single stage RO) equipment. A large water production capacity of 15T/H (inlet temperature of 25 ℃ -30 ℃). The machine occupies a small area, is easy to operate, convenient, easy to protect, and saves energy consumption. The low-pressure pipeline of the unit adopts Huanqi UPVC pipe, which can effectively avoid pipeline pollution. The high pressure pipeline is welded with SUS-304 stainless steel, and the inner Bull polishing is polished to avoid bacterial propagation and has good pressure resistance. The security filter part of the single stage reverse osmosis pure water equipment is made of stainless steel shell and connected together, with strong anti pollution ability. The RO membrane tube is made of FRP raw material, which is tensile, compressive, pollution resistant, and functionally stable. Make the purified water after initial purification go through the reverse osmosis membrane to become purified water. The entire system can achieve active water supply.
