In view of the different concentrations of DMAC waste water, adopt different treatment processes of multi-effect distillation or heat pump distillation, can recycle waste water of low concentration > 2%, so that the low concentration wastewater recycling has considerable economic benefits. DMAC wastewater treatment capacity is 5~ 30t / h. Recovery ≥99%.
Water ≤200ppm
HAC ≤30ppm
DMA ≤20ppm
