Working principle and characteristics of water treatment equipment

RO RO pretreatment process mainly includes activated carbon and fine filtration. Permeation is a natural phenomenon: water passes through the semi permeable membrane from the low solute concentration side to the high solute concentration side until the chemical potential of the solvent reaches equilibrium. In equilibrium, the pressure difference between the two sides of the membrane is equal to the osmotic pressure. This is the Osmosis phenomenon. Reverse osmosis means that if the pressure is applied at the high concentration side, the above mentioned osmotic effect can be stopped and reversed, so that the water is forced from the high concentration side to the low concentration side, and the water is purified. This phenomenon is called reverse osmosis (RO), and this semi permeable membrane is called reverse osmosis membrane.
