Die Casting Wastewater Treatment

Solution：

Most casting liquid with slight corrosion, and should be carried out before the evaporation. Under the condition of vacuum low temperature evaporation, water vapor condensation in the process of vacuum forming distilled water, collect to water storage tanks, because of the waste water containing hydrocarbons, relying on traditional evaporation machine can not be completely removed. Therefore, distilled water needs to be considered for post-treatment devices or activated carbon to achieve straight discharge standards. Through IVECDEST evaporator can reduce more than 98% of the amount of wastewater, the distilled liquid can recycle or reach discharge standards.

Application：

Aerospace

Automobile manufacturing

Communication divice

Metal production

Brief Introduction：

To avoid failure occurs in the process of production and ensure product quality, the mold release this auxiliary material in the die casting technology is indispensable. Dissolve or emulsion used release agent in the foundry in the wastewater discharge of enterprises, are not allowed to directly into the public drainage system. They are in most cases, together with other enterprise waste, expensive waste processing by the professional company.

Our technology can separate contaminants, including emulsified oils, to prepare crystalline distilled water. A great way to recycle water.

Using the worldwide technology process IVECDEST low temperature vacuum evaporation device to purify such industrial wastewater, the sewage cost can be significantly reduced. Extraction distillation water above 98%. As a result, the cost can also be reduced by more than 98%; COD can be reduced by 99%, which can reach the reuse standard or direct discharge.

Process Diagram：

Most of foundry waste liquid with slight corrosion, some neutralised before processing waste water into the evaporator. The water vapor condenses in the vacuum process to form distilled water, which is collected into the water storage tank, and the remaining trace waste is used for the next hazardous waste treatment. It can greatly reduce or even remove harmful chemicals and heavy metals contained in the waste liquid. The Greenlan evaporator can reduce the amount of wastewater by more than 98%, and the distillate can be reused or further treated to meet the middle water or discharge standards.
