Project background: The client is Metal Ecological City·Industrial Park.

Customer pain points: The customer is a local electroplating park and comprehensive sewage treatment station. Currently, the park has a stockpile of 20,000 tons of mixed concentrate that needs to be treated

Wastewater type: chemical nickel/chemical copper wastewater. INGREDIENTS: Nickel Sulfate, Copper Sulfate, Copper Chloride, Nitrate, Sulfate

Suggested solution: pretreatment (acid-base neutralization) + 3 BL-20T low-temperature evaporation systems + freeze crystallization

Investment analysis: 60T of mixed wastewater is neutralized with acid and alkali every day, and the supernatant is taken into the low-temperature evaporation system, and the remaining 83% of the concentrated solution is frozen and cooled into the centrifuge to achieve the effect of salt extraction
