  • Organic wastewater produced in the process of pharmaceutical production is the main pollution source, and its wastewater discharge accounts for 2% of the total wastewater discharge in China. Pharmaceutical industry wastewater mainly contains antibiotic wastewater, traditional Chinese medicine wastewater and chemical pharmaceutical wastewater. The main pollutants in pharmaceutical industry wastewater are suspended solids (SS), chemical oxygen demand (COD), biochemical oxygen demand (BOD), ammonia nitrogen (NH3-N), cyanide and volatile phenols and other toxic and harmful substances. The biochemical treatment process cannot be adopted directly. The MVR evaporator is used to treat the pharmaceutical wastewater, and the waste salt is recycled and the condensed water is reused.

    The new generation of MVR evaporator is internationally recognized as the most energy-efficient and environmental friendly evaporation concentration equipment. Once started, the system doesn't need fresh steam. The MVR system will transfer the lower energy steam to higher energy steam with higher temperature and high pressure which can be reused to heat the raw material. The steam condensate can be used for first stage preheating source for the raw material. In this close loop system, the secondary steam can be fully recycled and reused.

    When the saturated concentrate meets certain conditions (saturation, viscosity, etc.), the PLC control system will issue instructions to the solid-liquid separator, the valve opens automatically, and the concentrated liquid flows into the crystallizer. The saturated concentrated liquid is treated by crystallizer, and achieves solid liquid separation.

    The pharmaceutical industry's granules, Chinese patent medicine tablets, western medicine tablets and powder have higher temperature requirements.  Combined with MVR technology and low temperature multi effect evaporation technology, energy saving and also to maximize to keep the characteristics of raw materials to meet customer demand for industrial upgrading and energy saving target.
