YHDE has developed containerized zero-discharge wastewater treatment technology, which combines various advanced process technologies such as material separation, membrane concentration, and evaporation crystallization (customized treatment processes based on sewage conditions) to treat various types of wastewater. This ultimately achieves true "zero discharge." The "zero discharge" technology comprehensively applies physical, chemical, and biochemical processes such as membrane separation, evaporation crystallization, and drying to concentrate solid impurities in wastewater to a very high concentration. The vast majority of the treated water is reused in a closed-loop or discharged, with a small amount of water containing solid waste accompanying it, which can be managed based on the specific situation of each enterprise.
