RO reverse osmosis water treatment, also known as reverse osmosis water treatment technology, is a membrane separation technology that uses reverse osmosis membranes for water treatment.

The principle of reverse osmosis (RO) technology is to apply a pressure greater than the natural osmotic pressure on the raw water side, causing water molecules to reverse permeate from the side with higher concentration to the side with lower concentration. Due to the pore size of reverse osmosis membranes being hundreds or even thousands of times smaller than that of viruses and bacteria, various viruses, bacteria, heavy metals, solid soluble substances, contaminated organic matter, calcium and magnesium ions, etc. cannot pass through reverse osmosis membranes to achieve the goal of water purification and softening.

ROreverse osmosisThe main applications of water treatment

RO reverse osmosis water treatment technology has been widely applied in the following fields:

1. Preparation of high-purity water: Used for the preparation of high-purity water required by industries such as electronics, pharmaceuticals, and food.

2. Desalination of brackish water: The salt in brackish water is removed through reverse osmosis technology to obtain drinkable fresh water.

3. Wastewater treatment: In wastewater treatment processes, reverse osmosis technology can be used to remove harmful substances from wastewater, achieving wastewater reuse or standard discharge.

4. Beverage industry: producing purified drinking water, distilled water, natural water, mineral water, etc.

5. Other industries such as chemical, power generation, medical, etc. also require the use of RO reverse osmosis water treatment technology.

ROreverse osmosisProcess flow of water treatment

The standard process flow of RO reverse osmosis water treatment technology usually includes the following steps:

1. Raw water pretreatment: Preliminary treatment of raw water is carried out through sand filtration, activated carbon filtration, softening water equipment, etc., to reduce the pollution index and impurities such as residual nitrogen in the raw water.

2. Security filter: further remove small impurities and particles from the pre treated water to ensure that the water quality entering the reverse osmosis system meets the requirements.

3. Anti paint transparent host: Under the action of a high-pressure pump, raw water is separated through a anti paint transparent membrane to obtain purified water and concentrated water.

4. Post treatment system: Further treatment of purified water is carried out as needed, such as sterilization, ultrafiltration, etc.

5. Centralized water intake point: Transport the treated purified water to the centralized water intake point for user use.
