Coating Wastewater Treatment

Solution: 

Coating wastewater directly into IVECDEST vacuum evaporator without pretreatment, under the condition of vacuum low temperature evaporation, water vapor condensate to form distilled water, collecting to water storage tanks, only about 5% of the remaining traces of concentrate. It can greatly reduce and remove the organic matter COD and heavy metals in the waste liquid. Through the IVECDEST evaporator, the amount of wastewater can be reduced by more than 95%, and the distilling liquid can be reused as middle water or further processed to meet the discharge standards.

Application：

Plastic Spraying

Metal Products

Aerospace

Automobile Painting

Brief Introduction:

Wastewater source:

Coating wastewater mainly comes from the pre skim, skim, table, phosphating, passivation, pretreatment process; In the cathodic electrophoresis process and the middle coating and spray painting process, the coating wastewater contains pollutants such as resin, surfactant, heavy metal ions, pigments and so on. Especially, the electrophoresis wastewater and spray painting wastewater have complex composition, high concentration, large odor, and poor biochemical property.

Wastewater Characteristics :

The contents of COD and phosphorus are high. High heavy metal content;

Environmental impact:

High concentrations of organic matter, big pollution complicated composition, toxicity, refractory, great damage to the environment.

The purification of spraying wastewater is becoming more and more important in the coating industry and has become an indispensable process step to determine quality in recent years. Therefore, in view of the spraying waste water purification, more and more enterprises begin to adopt low-temperature vacuum distillation equipment. The advantage of such equipment quality after washing waste water purification.

In our zero waste production application center, Greenlan continuously develop the innovative technology which can significantly improve the quality of distilled water. For example, with the IVECDEST low-temperature vacuum evaporation technology of technology process, a set of ingenious systems can be prepared to meet the quality requirements, so as to obtain clear distilled water. This makes our IVECDEST cryogenic vacuum distillation system unique in the global market.
