Industrial production water, rinsing water, washing and other industrial production processes will produce a large number of wastewater containing a variety of high concentrations of pollutants. The waste water must be treated by internal system before discharged into the public sewage system or river, lake and ocean.
Many times, we cannot give clear water properties, such as composition of wastewater composition, TDS; and most of the time; components recycling economic value in wastewater are not high. Thermal separation technology in wastewater treatment should be a better choice.
When designing evaporation and crystallization system, we need to consider many factors, such as the composition of raw materials, the purpose of concentrated products, energy status, the price of electricity or steam, enterprise layout planning, etc.
The operation cost of evaporation crystallization equipment mainly refers to energy consumption. 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.
This is the popular zero discharge solution for electroplating industry, coating industry, pharmaceutical and pesticide industry, metal processing industry, paper industry and crude oil production industry etc. Through the comprehensive utilization of membrane technology, biochemical, oxidation, MVR evaporator and other technologies, the useful substances in wastewater can be recycled, and the effluent can be reused directly or discharged. The technology greatly reduces the treatment cost of waste liquid.
