چکیده
|
This work reports the elaboration of ceramic microfiltration membranes made by dry process and based on different moroccan pozzolans (pozzolan of n'aid said (pn),black pozzolan of hebri (bph) and red pozzolan of hebri (rph)). raw pozzolans were characterized by xrf,xrd and tga analysis. disks of 40 mm in diameter and 2±0.2 mm in thickness were elaborated by uniaxial pressing method and then sintered at 950 °c. elaborated membranes were characterized by sem analysis,shrinkage measurement,water porosity,mechanical strength,and chemical resistant. the morphology of top surface of membranes was homogenous and free from cracks. results showed that the average pore diameter was approximately 2.84,2.20 and 2.36 μm for pn,bph and rph membranes respectively. in the other hand,the optimized water permeability was 1424,843 and 1952 l/m2.h.bar respectively,after two hours of filtration. the elaborated membranes were tested to treat water washing of jeans and they were able to remove approximately 99% of turbidity.
