Heat Pump Vacuum low temperature crystallizer-Heavy Metal Wastewater treatment

Basic Introduction:

Customer Background:

The customer is located in Wuxi and its electroplating products cover the important fields of automobile, mechanical processing, railway, electronics, hardware and other industries. The main customers are: Foxconn, Shanghai Volkswagen, FAW-Volkswagen, Geely Automobile, Tianjin Toyota, Great Wall Motor, General Motors, Ford, Chrysler, Toyota, Nissan, Hyundai, Honda, BMW, Mercedes-Benz, Baowo and other automobile enterprises.

Customers produce electroplating wastewater in the production process. The main component is heavy metal wastewater containing zinc, nickel, copper, chromium and other heavy metals. Wastewater volume is about 1 ton/day.

Original Treatment Method: 

New project, zero liquid discharge.

Application of Greenlan Equipment:

The customer's wastewater is about 1 ton/day and the wastewater automatically enters the VESALT S-HP1000 heat pump scraper low-temperature drying and crystallization equipment, with a total daily treatment capacity of 1 ton. The waste liquid contains zinc, copper, nickel and other salts. After systematic treatment by the scraper crystallization system, about 95% of the distilled liquid can be extracted from the waste liquid, and only about 5% of the solid/semi-solid dry crystalline salt is left with moisture content≤20%.

Process Flow:

Electroplating wastewater without any pretreatment, automatically enters into S-HP1000 heat pump scraper low temperature drying crystallization equipment. Total daily processing capacity is 1 ton, extracting more than 95% of the distilled liquid in the waste and left solid dry crystalline salt with moisture content≤20%.
