Reverse Osmosis Water Equipment is an auxiliary device for producing pure water. During the treatment of reverse osmosis water, some people may develop misconceptions due to a lack of understanding of its principles. Therefore, in this issue, our large-scale reverse osmosis water purification equipment manufacturer is here to introduce the working principle of reverse osmosis water equipment.

Principle of Reverse Osmosis Water Equipment:

Section 1: Post-Processing Principle

1. The post-treatment section primarily involves further processing of the pure water extracted from the reverse osmosis main unit, should subsequent processes involve ion exchange or electro-deionization equipment.

2. It can produce industrial ultra-pure water. If used in domestic drinking water treatment processes, it is often followed by a post-treatment sterilization unit.

Section II: Preprocessing Principles

1. Comprising a quartz sand filtration unit, an activated carbon filtration unit, and a filtration unit, the primary purpose is to remove silt, rust, colloidal substances, suspended matter, colorants, odors, biochemical organic matter, and reduce the residual ammonia value and harmful pollutants in the raw water.

It is a water treatment system organized around reverse osmosis membranes, with a complete reverse osmosis system comprising pretreatment, the main reverse osmosis unit (membrane filtration), post-treatment, and system cleaning components.

Section 3: Explanation of Reverse Osmosis in RO Water Purification Equipment

Place equal volumes of dilute and concentrated seawater or saltwater on opposite sides of a container.

2. The solvent in the dilute solution will naturally pass through the semi-permeable membrane and flow towards the side with the concentrated solution.

The liquid level on the concentrated solution side will be higher than that on the dilute solution side, creating a pressure difference and reaching an osmotic equilibrium state.

4. Osmotic pressure is determined by the type of concentrated solution, its concentration, and temperature, which are unrelated to the properties of the semi-permeable membrane.

When a pressure greater than the osmotic pressure is applied to the side of the concentrated solution, the solvent in the concentrated solution will flow towards the dilute solution. This flow of the solvent is in the opposite direction of the original osmotic flow.
