Elaboration of new ceramic microfiltration membranes from mineral coal fly ash applied to waste water treatment

This membrane was applied to the treatment of the dying effluents generated by the washing baths in the textile industry. The performances in term of permeate flux and efficiency were determined and compared to those obtained using a commercial alumina microfiltration membrane. Almost the same stabilised permeate flux was obtained (about 100 l h−1 m−2). The quality of permeate was almost the same with the two membranes: the COD and color removal was 75% and 90% respectively.
