Development of an asymmetric carbon microfiltration membrane: Application to the treatment of industrial textile wastewater

摘要: Abstract Tubular carbon microfiltration membranes have been prepared using mineral coal powder (100 μm average particle size) mixed with phenolic resin solution and organic additives. The porosity of the support can be sharply controlled by fixing additives percentages, particles size homogeneity powder. A mesoporous active layer was deposited on inner face slip casting a deflocculated made (1.76 μm) suspended in solution. An an pore diameter 0.60 μm is obtained after carbonization under nitrogen atmosphere. membrane has very interesting characteristics regarding mechanical chemical resistances. application to treatment industrial textile wastewater shows good performances term permeate flux efficiency (retention COD salinity 50% 30% respectively almost total retention turbidity color).
