The printing and dyeing industry is a large water consumer. Printing and dyeing wastewater is characterized by high salinity and high chroma, and it is a kind of industrial wastewater that is more difficult to handle. Most domestic printing and dyeing companies' wastewater treatment systems get reused by the traditional double-membrane method. The process still has many problems: a water quantity of 30-40% of the total water volume is generated, high concentrations of water and concentrated water are difficult to handle with high chroma, and emissions are difficult to meet.
In response to such RO printing and dyeing wastewater treatment, Jiarong developed a complete set of solutions together with its partners, which is sufficient in completely solving the problem of concentrated dyeing wastewater。 Its core technology is advanced oxidation (AOP), high efficiency nanofiltration (MTNF) and high pressure reverse osmosis (MTRO)。
As a leading and experienced film supplier in China, Jiarong has supplied more than 200 sets of special separation membrane equipment, including high pressure equipment for tubular membranes, nanofiltration membranes and special reverse osmosis membranes。
To achieve zero discharge of printing and dyeing wastewater, Jiarong has a large-scale, leading-edge industrial application performance.
