Three-effect falling film + forced circulation evaporation system
**** Group (Benxi) The wastewater treatment station project for the **** R&D pilot and industrialization base project (Phase I) includes a high-concentration wastewater three-effect evaporation desalination system. The high-concentration, high-salinity organic wastewater generated from the process production of the wastewater treatment station at the **** Group (Benxi) Northern Pharmaceutical R&D pilot and industrialization base project (Phase I) is treated through the three-effect evaporation system. The evaporated water is sent to the next stage for discharge, while the solids are packaged and transported out. Ultimately, the high-salinity wastewater meets discharge standards, receiving unanimous praise from clients.
Distillation + Triple Effect Evaporation System
**** Technology Co., Ltd. 8T/H High Salinity Wastewater Distillation + Triple Effect Treatment Project. Design treatment scale: High salinity wastewater treatment capacity of 200t/d (8t/h). **** Technology Co., Ltd. operates in the field of UV curing in radiation curing, which is a globally encouraged green and environmentally friendly industry. The products can be widely applied in the fields of electronics, printing, food packaging, and medical materials, including photopolymer coatings, photosensitive imaging materials, photopolymer inks, and holographic laser imaging, in high-tech areas such as integrated circuits, flat panel displays, and 3D printing. They also have extensive applications in the medical beauty industry, such as dental materials and nail art. The company generates two types of high-concentration high-salinity organic wastewater during production that need to be treated. The first type is a mixed wastewater containing sodium chloride (about 5%), ammonium sulfate (in small amounts), tert-butanol (3%), toluene, sodium carbonate, and other oils, currently producing 20t of wastewater per day, which may expand to about 80t per day in the future. The second type is a mixed wastewater containing sodium carbonate (about 3.5%), sodium chloride (trace amounts), and other organic substances, currently producing 30t of wastewater per day, which may expand to about 120t per day in the future. The tert-butanol wastewater is designed to use distillation to recover high-concentration tert-butanol, which then enters the evaporation system for desalination. The condensed water from evaporation is included in the sewage treatment plant for biochemical treatment before being discharged in compliance with standards. The sodium carbonate high-salinity wastewater is directly evaporated for desalination, and the condensed water is reused in production. Customer satisfaction is very high, and the second phase of the project has been entrusted to our company.
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 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.
