JRO reverse osmosis water treatment equipment for secondary water treatment

Description :

　　The reverse osmosis water treatment equipment selects accessories from foreign manufacturers, adopts advanced foreign treatment technologies such as multi-stage pre filtration, reverse osmosis, nuclear grade mixed bed resin purification, dual wavelength ultraviolet digestion, and our company's unique process design to ensure the performance and stability of the product. The laboratory ultrapure water machine is designed as an integrated whole, integrating pre-treatment system, RO system, ultrapure water system, and post-treatment system, making it easy to operate and maintain. It is also possible to easily upgrade functions according to user needs.

　　The pretreatment system of reverse osmosis water treatment equipment usually consists of polypropylene fiber (PP) filters and activated carbon (AC) filters. For raw water with high hardness, a softening resin filter needs to be installed. PP filter element can efficiently remove mechanical particle impurities, rust, and large gel like substances above 5 μ m in raw water, protecting subsequent filters. Its characteristics are large pollutant capacity and low price. AC activated carbon filter can efficiently adsorb residual chlorine and some organic matter and colloids in raw water, protecting polyamide reverse osmosis composite membranes from residual chlorine oxidation. Softening resin can remove most of the calcium and magnesium ions in raw water, prevent subsequent scaling and blockage of the RO membrane surface, and improve water recovery rate.

　　The principle and function of reverse osmosis: Place dilute solutions (such as fresh water) and concentrated solutions (such as seawater or saltwater) of the same volume on both sides of a container, with a semi permeable membrane in the middle to block them. The solvent in the dilute solution will naturally pass through the semi permeable membrane and flow towards the concentrated solution side. The liquid level on the concentrated solution side will be higher than that of the dilute solution by a certain height, forming a pressure difference to achieve osmotic equilibrium. This pressure difference is the osmotic pressure. The magnitude of osmotic pressure depends on the type of concentrated solution, and the concentration and temperature are independent of the properties of the semi permeable membrane. If a pressure greater than the osmotic pressure is applied on the concentrated solution side, the solvent in the concentrated solution will flow towards the dilute solution, and the flow direction of this solvent is opposite to the original direction of permeation. This process is called reverse osmosis.
