Case
Easy and Simple Environmental Low-Temperature MVR Evaporation System
**Pharmaceutical Factory Co., Ltd. (Shanghai Pharmaceutical Group), low-temperature MVR treatment project for wastewater.
**The pharmaceutical factory is a comprehensive pharmaceutical enterprise that focuses equally on chemical raw materials, chemical drug formulations, and the comprehensive development of science, industry, and trade. This system is designed for the hydrochlorothiazide raw material workshop, aiming to remove aniline compounds from the raw water. The designed treatment capacity is 10 t/d, pH: 4-8, solid content is 7.6%, including about 3.2% sodium chloride, about 3.8% ammonium chloride, and about 0.6% other organic substances, with COD around 3000 mg/L, and organic substances do not volatilize during evaporation. The design employs low-temperature MVR evaporation (60-65°C) to concentrate 5 times, with the discharge resulting in cold crystallization of organic substances. The high-salinity, high-ammonia mother liquor undergoes alkaline deamination to produce ammonia water, with a designed deamination rate of 90%. The low-ammonia brine after deamination is dripped into the biochemical system for compliant discharge. The evaporated condensate is reused in production. It meets production needs, and customer satisfaction is very high.
