Vacuum evaporator is widely applied in industrial wastewater treatment. It evaporates water under vacuum condition(-0.098mpa). The wastewater boiling temperature is 35℃. Clear water is separated from the waste and leave small volume of high concentrated liquid. 

The drying crystallization system is used in industrial wastewater zero discharge. It evaporates water in a special designed vacuum condition. Water is evaporated and dry crystallization is left. The water can be reused to production line. It is a true sense of zero liquid discharge.

At Greenlan, we design and install vacuum evaporators for industrial wastewater treatment. Vacuum evaporators have been proven to be one of the most efficient solutions for industrial wastewater treatment. It’s highly inclusive of wastewater and has lower request to inlet, which can be effectively used for High difficulty wastewater, high salt wastewater and high COD wastewater treatment, etc. Vacuum evaporation can extract clear water from waste and greatly reduce wastewater volume.

Vacuum evaporation is a technique to separate water from waste. Clear water is extracted by evaporation to discharge or reuse. The pollutant is left as high concentrated liquid or even solid crystallization waste. This greatly reduces the wastewater volume.

S-ME1 thermal scraper drying crystallization equipment, using a single module structure. It uses alternative energy heating such as steam to distill and dry the wastewater at a low temperature of 35℃. The scraper continues to stir the tank wall and wastewater prevents the crystallization from condensate on the tank wall. Finally, the wastewater is treated into a dry powder solid, and the dry powder solid is automatically discharged.

S-ME2 steam type scraper drying mold, using a double module structure. Under the vacuum condition, the low temperature continues to remain at 35 ℃. The evaporation chamber is equipped with a scraper, which continuously stirring the waste liquid, and finally drying the waste liquid into solid or semi-solid waste. The scraper automatically discharges the waste from the tank.
