Wastewater field

Polluted water produced in the production process, such as untreated direct discharge into the water environment, lakes, rivers and groundwater pollution, polluted water, water quality complex, directly affecting the survival of human beings and health, so the treatment of wastewater is an indispensable and urgent problem to be solved.

▼Electroplating industry wastewater

The main pollutants in electroplating wastewater are heavy metals, heavy metals such as hexavalent chromium, trivalent chromium, copper ions, nickel ions, zinc ions, etc. The wastewater production processes involved are as follows: plate plating cleaning wastewater, stainless steel pieces of acid pickling pre-treatment wastewater, galvanizing cleaning wastewater, anodic oxidation cleaning wastewater, chemical nickel cleaning wastewater, and other types of metal surface treatment may be generated by the heavy metal-containing wastewater.

Electroplating industry wastewater containing heavy metal wastewater according to the customer's requirements can be discharged or supporting MVR mechanical compression evaporation equipment to achieve zero wastewater discharge.

▼New energy industry wastewater

New energy industry wastewater generation source is mainly lithium battery positive and negative electrode cleaning water, the main pollutants are conductive black carbon, NMP and other pollutants. The concentration of pollutants in the wastewater is high, as dangerous goods wastewater entrusted to a third-party agency to deal with the high cost, the use of low-temperature evaporation equipment, wastewater can achieve discharge standards, while the waste liquid minimization treatment, reduce corporate costs.

▼ Metal Processing Industry Wastewater

Metal processing wastewater is mainly cooling cutting fluid and lubricant used in the metal processing process, through the wastewater as a hazardous material wastewater transfer treatment, the transfer cost is higher, the use of low-temperature evaporation equipment for wastewater concentration and reduction of treatment, while the distillation of the condensate can be reused or discharged to meet the standards to reduce the cost of enterprises. 

▼High Salt Wastewater Industry

High-salt wastewater mainly contains calcium chloride, magnesium chloride, potassium chloride, ammonium chloride and sodium chloride and other types of high salinity wastewater, which is highly saline and highly corrosive, according to the corrosive nature of the wastewater, different materials can be selected, such as: 316L, 2205 duplex steel, titanium (TA2) materials. According to the size of water volume can choose MVR mechanical compression evaporation equipment or low temperature evaporation equipment.

This kind of wastewater involves many industries, such as: chemical industry, pharmaceutical industry, metallurgical industry, coal chemical industry, garbage leachate and other types of high salt wastewater.

▼Printing and Dyeing Industry

Printing and dyeing production process generates a large amount of sodium hydroxide wastewater, this kind of wastewater is highly alkaline and corrosive, the traditional treatment method has high energy consumption and low efficiency, it is difficult to meet the present environmental protection requirements. In order to realize efficient treatment of wastewater and resource recovery, MVR mechanical compression evaporation equipment is adopted.

▼Kitchen and domestic wastewater

Kitchen wastewater is mainly kitchen washing, tableware cleaning, food processing, ground cleaning, kitchen waste leachate, etc. It contains food residues, oil and grease, and cleaning agents, etc. This type of wastewater is usually characterized by high COD, high oil and grease, high salinity and low pH value.
