Since the production of Blue Sky Additives, the company has been actively looking for treatment methods in order to ensure the efficiency of production wastewater. Today, the company ordered a three-effect evaporator for sewage treatment equipment from Hebei Dingwei. The production wastewater is treated and discharged to the sewage treatment plant. On the one hand, it eliminates environmental pollution, and on the other hand, it also brings certain economic benefits of by-products to the company.
