Background
By the reverse osmosis process, water can be passed from a solution with a high concentration to a solution with a low concentration. Since inorganic ions, colloidal substances and macromolecular solutes cannot pass through the reverse osmosis cartridge, unwanted substances remain at the end of the high concentration solution and the lower concentration end of the solution receives purified pure water during this process. The process of the core component reverse osmosis filter element of the water purifier is actually a liquid concentration process, the salt content in water is continuously increased along with the water flowing through the surface of the reverse osmosis filter element, and the osmotic pressure of the water is also continuously increased. When the osmotic pressure increases to the pressure of the booster pump, water cannot flow into the clean water side through the reverse osmosis cartridge. The part of the water which fails to pass is the waste water generated in the process of making water.
