Specifications

Performance index:

The full-automatic water treatment and recycle equipment for electroplating cleaning, which is suitable for production lines of different specifications from the large-scale, medium-sized to small-scale. This equipment adopts the international advanced technology, which is to separate the ions with metals from the waste water, and the water can go back the potcher to have the reuse, the metal ions after the concentration will be added into plating bath directly. The technology have changed the treatment methods of traditional electroplating rinse water thoroughly and ensured the rinse water quality stable, and reduced the sewage discharge fees, created economic benefits, improved product quality, and then reached the requirements of environmental protection and cleaning electroplating.

1. Electroplating pure water for electroplating industry

In the electroplating coating industry, in order to increase the surface finish, brightness, adhesion of plating workpieces, the preparation of electroplating solution needs the pure water whose electric conductivity should be below 15μS/cm, in addition, when rinse the plating workpieces, we should use the electroplating pure water whose conductivity should be below 10μS/cm. The water treatment systems for the electroplating industry including pure water system for the electroplating solution preparation before electroplating, the rare metals recovery in the electroplating rinse sewage, rinse water recycle, electroplating sewage treatment zero discharge system. Generally speaking, the system is composed of pretreatment, ultrafiltration, RO, ion exchange, EDI equipment etc, to satisfy the requirements of different water qualities in electroplating industry.

2. Technology process of preparing electroplating pure water

High-efficiency RO + EDI:

Tap water → electric valve →multi-media filter →activated carbon filter →water softener →middle water tank →PH regulating system →high-efficiency mixer →precision filter →high-efficiency RO →middle water tank →EDI water pump →EDI system →microfilter →water-use point

3. Electroplating pure water equipment features

The traditional preparation technology of electroplating pure water equipment usually adopts ion exchange resin to prepare, but the use of ion exchange resin can cause the frequent resin regeneration, which will consume materials and labor. Our company has gained years of practical experiment, at the same time, combined with the newest membrane separation technology, used low pressure RO + ion exchange system (or EDI) to prepare the electroplating ultrapure water, compared with conventional technology, this technology has the lower operation costs and reliable operation. Furthermore, this technology has the lower construction cost, which is safe and reliable.

4. Application fields of electroplating water purifier

•pure water for the electroplating (gold-plating, silver plating, plastic electroplating, chromium plating, zinc plating), electroplating ultrapure water for glass plating.
    •pure water for ultrasonic cleaning, pure water or ultrapure water for chemical electroplating and electrophoresis
    •pure water or ultrapure water for surface coating and cleaning of automobiles, household appliances, construction products
    •pure water or ultrapure water for surface treatment of other requirements

Pure water equipments for electroplating manufactured by our company, the pure water can meet the electronics department ultrapure water quality standards. It has been divided into four grades: 15MΩ×cm, 10MΩ×cm, 5MΩ×cm and 1MΩ×cm. High pure water equipments for electroplating has adopted the international advanced RO technology and EDI desalinization technology to prepare the deionized water, which is a kind of preparation technology of pure physical process. This kind of high pure water equipment can be operated continuously in the long term with automatic and simple operation, furthermore, the water quality can stay stable in the long term, no pollutant discharge, the cost of preparing pure water is low. According to different requirements of water qualities, we have adopted different water treatment equipments, which can satisfy the water quality standards of different grades.
