The desalted water equipment used in chemical industry can satisfy the practical production needs of many companies, and the customers can adjust the output of the equipment according to their own production needs, so that the water equipment used in chemical industry can satisfy their own needs and will not cause waste. The effluent water quality of desalted water equipment is very good, which conforms to the hygienic standard of food water equipment stipulated by the state and the practical production demand of the company.

Process flow of desalted water equipment for chemical industry

1. Selection of ion exchange method, the process is as follows.

Raw Water Raw Water Pressure Pump Multimedia Filter Activated Carbon Filter Softener Fine Filter Anionic Resin Filter Bed Anionic Resin Mixed Bed Microporous Filter Water Point

2. Select the reverse osmosis + mixed bed method, the process is as follows.

Tap water pipe network → raw water pump → flocculation dosing → mechanical filter → activated carbon filter → scale inhibition dosing → security filter → high pressure pump → reverse osmosis equipment → central water tank → mixed bed pump → mixed bed equipment → fine filter → demineralised water tank

3. Selecting EDI method, the flow chart is as follows.

In the desalted water treatment system used in chemical industry, hollow fibers with diameter of 1 mm are usually used to remove suspended substances and colloids from raw water. The biggest problem of UF used as pretreatment is membrane fouling and blockage of membrane holes. Therefore, pre-filters are often set in front to remove large-sized suspended substances and pre-filtration. Pre-addition of flocculants such as PAC (polypropylene acid) can improve water quality and reduce membrane resistance. The control system is programmed by industrial computer, which can automatically start and stop, add medicine and scour, and automatically monitor various operation parameters for production management.
