Project Background:
       Conventional treatment process is "coagulation and precipitation + filtration", which is a long process, with a large equipment footprint and high operating costs. Moreover, conventional organic ultrafiltration membrane technology cannot work under high suspended solids conditions, and ceramic and tubular membranes have high equipment costs, high pressure and high mis-flow ratios, and high energy consumption. Our ultra-microfiltration membrane module perfectly solves the above problems, realizing low pressure, low mis-flow ratio, large flux, long-term stability and high efficiency in removing SS, and the turbidity of the effluent reaches 0.2NTU.

New PTFE hollow fiber membrane group filtration of coal wastewater site 

      The use of ultra-microfiltration membrane filtration, not only to simplify the conventional process, but also significantly improve the efficiency and reduce the cost of coal wastewater treatment, the two specific technology comparison shown in Table 1:
