Case
Zero Discharge MVR Evaporation System for Electroplating Wastewater
Environmental Technology Co., Ltd. operates in the areas of research and development, and services related to environmental energy technology; research, design, manufacturing, sales, installation, maintenance, and technical services of environmental protection equipment, water treatment equipment, and resource reuse equipment; sales of chemical raw materials (excluding hazardous materials). The company generates high-concentration, high-salinity organic wastewater during production that needs to be disposed of. The electroplating wastewater treatment system has a capacity of 0.5T/H MVR evaporation crystallization with zero discharge. This system is designed for an evaporation rate of 0.5t/h, using the concentrated RO wastewater from previous systems and some high-concentration mother liquor as the source of treated water. The treated water has a TDS of less than 500ppm, receiving unanimous praise from customers.
Low Temperature MVR Evaporation System
***** Co., Ltd. (Shanghai Pharmaceutical Group) is implementing a low-temperature MVR treatment project for wastewater. ***** is a comprehensive pharmaceutical enterprise that focuses equally on chemical raw materials, chemical formulations, and the development of science, technology, and trade. This system is designed to support the hydrochlorothiazide raw material workshop, with the aim of removing aniline compounds from the raw water. The designed treatment capacity is 10 t/d, with a pH of 4-8 and a solid content of 7.6%, which includes approximately 3.2% sodium chloride, 3.8% ammonium chloride, and about 0.6% other organic substances, with a COD of approximately 3000 mg/L. The organic substances do not volatilize during evaporation. The design employs low-temperature MVR evaporation (60-65°C) to concentrate the solution by a factor of 5, resulting in the cold crystallization of organic substances. The high-salinity, high-ammonia mother liquor undergoes alkaline treatment to remove ammonia and produce ammonia water, with a designed ammonia removal rate of 90%. The low-ammonia brine after deammoniation is then added to the biochemical system for compliant discharge. The evaporated condensate is reused in production. This setup meets production needs and has received high customer satisfaction.
Sodium Chloride Solution MVR Evaporation Crystallization Project
**** Chemical Co., Ltd. is a technology-based manufacturing enterprise that produces intermediates for pharmaceuticals and pesticides.
High-salinity wastewater double-effect evaporation concentration project
This project includes two sets of 8 tons/hour double-effect evaporation concentration devices. The system operates stably and has a high degree of automation. This device meets production needs, and customer satisfaction is very high.
High-salinity wastewater three-effect evaporation concentration project
This project mainly deals with mixed wastewater from various workshops, with an evaporation capacity of 48 tons per day (2 tons per hour). After the wastewater is evaporated and concentrated, it enters the centrifugation separation stage, and the system has a high degree of automation.
