Treating wastewater from the machining industry’s metal surface spraying and cleaning processes presents several challenges:
High Concentrations of Contaminants: The wastewater often contains oils, solvents, heavy metals, and fine particulates, which are difficult to separate and treat effectively.
Complex Chemical Composition: The varied chemicals used in metal cleaning and surface treatment can lead to complex wastewater composition, requiring multi-step treatment processes.
Emulsified Oils: Oils in the wastewater are often emulsified, making traditional separation techniques less effective and requiring specialized treatments like chemical demulsification.
Heavy Metal Removal: Removing heavy metals such as lead, chromium, and nickel is challenging due to their tendency to form stable complexes in water.
Regulatory Compliance: Meeting stringent environmental regulations for discharge, especially for heavy metals and toxic substances, adds complexity to the treatment process.
High Treatment Costs: The need for advanced treatment technologies and frequent maintenance drives up the cost of wastewater treatment in this sector.
Customers is heavy equipment manufacturing industry, mainly engaged in the installation of large port equipment, engineering ships and large metal structural parts and their parts and accessories, production lines using waterborne paint instead of traditional oil paint, waterborne paint as environmental protection exemption coating, which is eco-friendly with nearly zero VOC emissions. However, the spray liquid wastewater from this process contains high levels of organic substances and some inorganic acids, alkalis, and salts, resulting in high COD levels. Additionally, the machining equipment uses metal coolants that develop odors over time, further increasing the COD content. Previously, disposal costs were 7,000 RMB per ton. Our solution involves a pre-filtration system, LT-1T evaporator, and ceramic membrane filtration. This process reduces sewage discharge and meets reuse requirements. Ultimately, the customer chose our 1000L/D low-temperature evaporation distillation equipment to meet their reuse needs.
