6TPH Drinking Water Making Machine RO Water Treatment System

Drinking water RO system membrane:

It is a semi-permeable membrane artificially synthesized by a special process in order to realize the reverse osmosis phenomenon of the aqueous solution. The pore size of the reverse osmosis membrane is 0.0001µm, and only the solvent in the aqueous solution, water, can pass through, while its solute cannot pass through the reverse osmosis membrane. The diameter of the virus is 0.02-0.4µm, and the diameter of the bacteria is 0.4-1.0µm. Therefore, the water passing through the reverse osmosis membrane is truly pure water.

Working Process of Drinking Water RO System

How does drinking water RO system membrane works?

A membrane that is selective for permeable substances is called a semi-permeable membrane, and a membrane that can only permeate a solvent but cannot permeate a solute is generally called an ideal semi-permeable membrane. When the same volume of dilute solution (such as fresh water) and concentrated solution (such as salt water) are placed on both sides of the semipermeable membrane, the solvent in the dilute solution will naturally pass through the semipermeable membrane and flow to the concentrated solution side spontaneously, This phenomenon is called penetration. When the osmosis reaches equilibrium, the liquid level on the side of the concentrated solution will be higher than the liquid level of the dilute solution by a certain height, that is, a pressure difference is formed, and this pressure difference is the osmotic pressure (see the figure for the working principle of the reverse osmosis membrane).
