 Industrial wastewater treatment--metallurgical industry wastewater  Industrial wastewater treatment--printing and dyeing wastewater


 The  main  characteristics  of  metallurgical  wastewater  are  large  water  volume,  diverse  types,   Printing  and  dyeing  wastewater  has  the  characteristics  of  large  water  volume,  high  organic
 complex  and  variable  water  quality.  The  selection  of  treatment  methods  for  metallurgical   pollutant  concentration,  deep  chroma,  large  alkaline,  large  water  quality,  and  complex
 wastewater  should  be  tailored  according  to  the  water  quality,  quantity,  and  effluent  quality   composition. It is one of the difficult industrial wastewater. Improving wastewater reuse rate and
 requirements of metallurgical wastewater. JIUWU HI-TECH    has developed key technologies such   reducing pollutant emissions are urgent issues that need to be addressed in the industry. JIUWU
 as membrane integrated high magnification concentration, salt separation, and waste salt resource   HI-TECH  has independently developed the ceramic membrane direct filtration technology for alkali
 utilization, successfully solving the problems of wastewater discharge and application difficulties in   recovery  of  desizing  wastewater,  which  has  been  widely  applied  and  achieved  good  economic
 the metallurgical industry.  benefits.  We  have  developed  efficient  biochemical  coupled  advanced  oxidation  process  and
               membrane integrated coupled freezing crystallization process for wastewater reduction and reuse,
 Technical advantages  achieving standard discharge and reuse of wastewater, as well as resource utilization of waste salt.


                Technical advantages
 · High-efficiency dual-membrane technology, short process, less occupied;
 ·  High  magnification  concentration  of  wastewater,  the  amount  of  evaporation  is  small,  and  the
 energy consumption is low;  · Stable and high-quality recycled water quality;
 · Effective ion deployment, Utilization of waste salt resources.
                · After the high-power concentration, the scale of the evaporator is small;
                · High quality by-product salt with high economic benefits.
