Membrane separation technology is a new type of membrane separation equipment that uses reverse osmosis membranes to separate the concentration of solvents and substances in a solution under working pressure. The selective permeability of reverse osmosis membranes to solutions and the effectiveness of external driving forces are used to break free from osmotic pressure, thereby enabling solvents to penetrate membrane separation technology. But how can RO reverse osmosis equipment have sewage?

The basic principle of reverse osmosis device reverse osmosis membrane is to place the same volume of dilute solution and concentrated solution on both sides of a vessel containing a semi permeable membrane in the middle. The solvent in the dilute solution will naturally penetrate the semi permeable membrane and flow into the concentrated solution side. It will be higher than the liquid level gauge of the solution by a certain aspect ratio, generating a pressure difference to achieve infiltration equilibrium. The pressure difference is the osmotic pressure. The size of osmotic pressure depends on the type of extraction solution, concentration value, temperature, and the characteristics of its semi permeable membrane.

If a working pressure exceeding the osmotic pressure is released on the side of the concentrated solution, the solvent in the concentrated solution will flow into the dilute solution. The direction of the solvent flow is reversed from the initial infiltration direction. The entire process is called RO reverse osmosis. According to the entire process of RO reverse osmosis, water can flow from solutions with higher concentrations to solutions with lower concentrations. Due to the inability of inorganic cations, colloidal solution chemicals, and biomolecular solutions to adhere to reverse osmosis membranes, unused chemicals are left at the tail end of the solution throughout the entire process, while the higher concentration is maintained, while the lower concentration at the tail end is the pure liquid obtained.

Technical considerations for the selection of reverse osmosis devices: Today's key solutions include activated carbon filtration, activated oxygen solution, and membrane separation technology. Microfiltration and ultrafiltration membranes in membrane separation technology cannot remove various low molecular structure chemicals. The water purifier uses purified water membrane separation technology. Reverse osmosis membranes can block the concentration of various inorganic cations, colloidal solution chemicals, and biological macromolecules in water, thereby obtaining mineral water. It can also be used for pre concentration of organic chemical solutions of polymer materials. Due to its simple RO process and energy-saving nature, it has developed rapidly in the past 20 years
