How the working principle works
RO-reverse osmosis pretreatment process is mainly activated carbon and fine filter.
Penetration is a natural phenomenon: water passes through the semipermeable membrane, from the low solute concentration side to the high solute concentration side until the solvate degree reaches equilibrium.
When the balance, the pressure difference on both sides of the membrane is equal to the osmotic pressure.
Reverse osmosis means that if the pressure on the side of the high pressure, will be able to stop the above mentioned infiltration effect and reverse, so that water from high concentrations forced to the low concentration of the side, the water purification.
This phenomenon is called reverse osmosis (reverse osmosis), which is called reverse osmosis membrane.
