In the electroplating and coating industry, in order to increase the surface smoothness, brightness, and adhesion of plated parts, pure water with a conductivity of less than 15uS/cm is required for the preparation of electroplating solution. In addition, pure water with a conductivity of less than 10uS/cm is also required for cleaning during the rinsing of plated parts. The water treatment system in the electroplating industry includes the pure water treatment system required for the preparation of electroplating solution before electroplating, and the zero discharge system for the recycling and reuse of rare metals in electroplating rinsing wastewater. Usually, the system is composed of a combination of ultrafiltration devices, reverse osmosis devices, ion exchange devices, EDI devices, etc., to meet the water quality requirements of the electroplating industry.

The traditional preparation process for ultra pure water in the electroplating industry usually uses ion exchange resin to produce a. However, the use of ion exchange resin usually requires frequent resin regeneration, which consumes material resources and labor. After years of practice and combined with the latest membrane separation technology, our company often uses a combination of reverse osmosis and ion exchange system (or EDI) to prepare ultra pure water. Compared with traditional processes, this process has the advantage of low operating cost (the regeneration cycle of ion exchangers is greatly extended) and reliable operation. Compared with the latest technology, it has the advantages of low cost and easy availability of consumables. The reverse osmosis process technology is advanced and reliable.

1. Using EDI method, the process is as follows:

Raw water booster pump, multi-media filter, activated carbon filter, water softener, precision filter, primary reverse osmosis machine, intermediate water tank, intermediate water pump, EDI system, microporous filter, water consumption point

2. The ion exchange method is adopted, and the process is as follows:

Raw water pressure pump, multi-media filter, activated carbon filter, water softener, precision filter, cation resin filter bed, anion resin filter bed, anion and cation resin mixed bed, microporous filter, water point

3. Adopting a two-stage reverse osmosis method, the process is as follows:

Raw water pressure pump, multi-media filter, activated carbon filter, water softener, precision filter, first stage reverse osmosis pH regulation, intermediate water tank, second stage reverse osmosis (reverse osmosis membrane surface with positive charge), purified water tank, pure water pump, microporous filter, water consumption point
