Original Treatment Method：

New project, wastewater zero discharge.

Application of Greenlan Equipment：

Wastewater volume is about 72 tons/day. Wastewater automatically goes into 3 sets of S - VE24000 low-temperature vacuum distillation system with daily capacity of 72 tons. The waste liquid contains a certain amount of copper sulfate salt, such as by cryogenic and after processing, it can be extract more than 80% of the distilled water discharged to wastewater treatment station. The remaining high concentration mother liquor is used for the next step of copper extraction.

Process Flow:

Without any pretreatment, the wastewater automatically enters three sets of S-VE24000 low-temperature vacuum distillation system, with a total treatment capacity of 72 tons per day, extracting more than 80% of the distilled liquid in the waste liquid, and separating the high-concentration mother liquor.
