Pharmaceutical wastewater is a kind of fluids that is difficult to be treated. With properties of complex composition, high organic content, high toxicity, deep color and high salt content, especially its complex biochemical and intermittent discharge, the pharmaceutical wastewater cannot be directly treated by biochemical treatment process. Pharmaceutical wastewater has gradually become one of the important pollution resources.

The treatment methods for pharmaceutical wastewater includes biological method, chemical method, physical and chemical method, etc. However, due to the variety of pharmaceutical wastewater quality, a single treatment method of pharmaceutical wastewater is not able to achieve the treatment effect.

Propellent MVR evaporator is a new type of efficient, energy-saving and economic evaporation technology and equipment. Our evaporators have been widely used in the concentration and extraction of medicine in the pharmaceutical industry, as well as evaporation, concentration and crystallization in the chemical and biological pharmaceutical production process.

The process of using MVR evaporator to treat pharmaceutical wastewater:

Pharmaceutical industry wastewater is heated and concentrated by a heater and then flowed into the MVR evaporator through a pump. In evaporator, the pharmaceutical industry wastewater is heated, evaporated and concentrated by steam, and the distilled water is returned to the preheater to preheat the stock solution. The concentrated liquid and steam produced enter the liquid-gas separator, through which the separated steam enters the compressor. The separated concentrate is returned directly to the collection tank, and the concentrate is treated to recover the useful substances contained in it. When the saturated concentrate treated by MVR evaporation meets certain conditions (saturation, viscosity, etc.), the PLC control system will give instructions to the solid-liquid separator, the valve will open automatically, and the concentrate will flow into the mold. Solid is precipitated from saturated concentrated liquid after treatment with crystallizer to realize the separation of solid and liquid

As an advanced evaporation technology, MVR system gradually replaces the traditional evaporator, which not only reduces energy consumption, but also greatly improves heat exchange efficiency and saves costs. Propellent MVR evaporator provides comprehensive evaporation system solutions for customers.
