Introduction:

Reverse osmosis equipment, as an efficient membrane separation technology, plays an increasingly important role in modern industry and life. It can effectively remove impurities such as dissolved salts, colloids, microorganisms, and organic matter from water, producing high-quality pure water. With the continuous advancement of technology and the increasing demand for water quality, the application fields of reverse osmosis equipment are also constantly expanding. This article will provide a detailed introduction to the application of reverse osmosis equipment in different industries.

Working principle of reverse osmosis equipment:

Reverse osmosis is a membrane separation operation that uses pressure difference as a driving force to separate solvents from a solution. Reverse osmosis membrane is a semi permeable membrane that only allows solvent molecules to pass through while preventing solute molecules from passing through. When dilute and concentrated solutions of the same volume are placed on both sides of a reverse osmosis membrane, the solvent in the dilute solution will naturally flow through the semi permeable membrane towards the concentrated solution, and this phenomenon is called permeation. When a pressure greater than the osmotic pressure is applied to the concentrated solution side, the flow direction of the solvent will reverse, that is, it will flow from the concentrated solution side to the dilute solution side. This process is called reverse osmosis.

Application of reverse osmosis equipment in different industries:

1. Electronic industry

In the electronics industry, reverse osmosis equipment is mainly used to produce ultrapure water to meet the extremely high water quality requirements of processes such as electronic chip manufacturing, semiconductor production, and LCD display manufacturing.

If there are impurities in the water, it may cause performance degradation, short circuit, corrosion and other problems of electronic components, seriously affecting the quality and reliability of electronic products.

By combining reverse osmosis equipment with other water treatment technologies such as ion exchange, ultrafiltration, and ultraviolet disinfection, ultra pure water with a resistivity of up to 18.2 M Ω· cm can be produced. This ultra pure water contains almost no impurities and can meet the stringent water quality requirements of the electronics industry. In addition, reverse osmosis equipment has the advantages of high automation, simple operation, and stable operation, which can provide reliable water treatment solutions for the electronics industry.
