Application of Reverse Osmosis Membrane Technology in Industrial Purified Water/Electronic Ultra-Pure Water

With the continuous growth of industrial manufacturing and development, severe environmental pollution has led to rapid deterioration in water quality. Consequently, there is an increasing demand for high-quality water for cleaning industrial and electronic products. Purified water is primarily used in production for cleaning and preparing various solutions and slurries. Different electronic components require varying water quality standards, making water quality a crucial factor affecting product yield and production costs.

Insufficient water quality during the manufacturing processes of electronics, batteries, power, semiconductors, LCD displays, photovoltaics, and other industries can lead to serious consequences, such as complicating subsequent process treatments and shortening product lifespan.

To achieve optimal purified water production, Reverse Osmosis (RO) technology has been widely adopted in the field of water treatment. It has become a common technology used in industries like electronic manufacturing for producing ultra-pure water. Typical equipment for producing electronic ultra-pure water includes multi-media filters, activated carbon filters, sodium ion exchangers, and precision filters as part of the pretreatment system. The main equipment systems comprise RO membrane systems and Ion Exchange Mixed Beds (EDI Electrodeionization Systems).

Common Processes for Producing Electronic Ultra-Pure Water:

One common process involves combining RO water treatment equipment with ion exchange equipment to produce electronic ultra-pure water. The basic process flow is as follows: Raw water → Multi-media filter → Activated carbon filter → Precision filter → Intermediate water tank → RO equipment → Mixed bed (Dual bed) → Ultra-pure water tank → Ultra-pure water pump → Post security filter → Point of use.

Another economically viable and promising method for producing ultra-pure water involves combining RO equipment with Electrodialysis (EDI) equipment. The basic process flow is: Raw water → Multi-media filter → Activated carbon filter → Precision filter → Intermediate water tank → RO equipment → Electrodialysis (EDI) → Ultra-pure water tank → Ultra-pure water pump → Post security filter → Point of use.

Note: Different models of equipment for producing electronic ultra-pure water may involve variations in processing steps. Consultation with professionals is recommended for specific needs.

Application Areas of Dalton Membrane Components in Industrial Purified Water/Electronic Ultra-Pure Water Industry

Dalton membrane components can be applied in various purified water equipment used in industrial production. They are used across multiple sectors including electronics, power generation, electroplating, lighting appliances, laboratories, biotechnology, petroleum refining, steel manufacturing, papermaking, daily chemicals, construction materials, coatings manufacturing, battery production, semiconductor manufacturing, fine chemicals, optics, and more.

In conclusion, the use of RO membrane technology in industrial purified water and electronic ultra-pure water systems is pivotal for meeting stringent water quality requirements in manufacturing processes. Its application ensures high efficiency, reliability, and sustainability in industrial water treatment practices.
