PART 02 Proficient in membrane technology and
Industrial wastewater treatment--metallurgical industry wastewater
The main characteristics of metallurgical wastewater are large water volume, diverse types,
complex and variable water quality. The selection of treatment methods for metallurgical
wastewater should be tailored according to the water quality, quantity, and effluent quality
requirements of metallurgical wastewater. JIUWU HI-TECH has developed key technologies such
as membrane integrated high magnification concentration, salt separation, and waste salt resource
utilization, successfully solving the problems of wastewater discharge and application difficulties in
the metallurgical industry.
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;
· Effective ion deployment, Utilization of waste salt resources.

Industrial wastewater treatment--printing and dyeing wastewater
Printing and dyeing wastewater has the characteristics of large water volume, high organic
pollutant concentration, deep chroma, large alkaline, large water quality, and complex
composition. It is one of the difficult industrial wastewater. Improving wastewater reuse rate and
reducing pollutant emissions are urgent issues that need to be addressed in the industry. JIUWU
HI-TECH has independently developed the ceramic membrane direct filtration technology for alkali
recovery of desizing wastewater, which has been widely applied and achieved good economic
benefits. We have developed efficient biochemical coupled advanced oxidation process and
membrane integrated coupled freezing crystallization process for wastewater reduction and reuse,
achieving standard discharge and reuse of wastewater, as well as resource utilization of waste salt.
Technical advantages
· Stable and high-quality recycled water quality；
· After the high-power concentration, the scale of the evaporator is small;
· High quality by-product salt with high economic benefits.
