Popis: The study deals with the treatment, by nanofiltration, of effluents generated after rinsing the vats used for the manufacture of inks (pen cartridges). The first part of the study (bibliographical) shows that membrane processes are operational in different industrial areas for the decoloration of effluents but the number of nanofiltration plants is still limited. In the second part (experimental) two tubular organic membranes (Koch-Weizmann MPT20 an MPT31), selected according to their molecular weight cut-off (450 dalton) and their resistance to solvents and acid solutions, are performed and compared. The study shows that performances (i.e. permeation flux and retention rate) of MPT20 membrane are linked noticeably to hydrodynamic parameters (pressure, velocity). Furthermore, for the two membranes tested the transport mechanism across the medium is typically diffusional. The studies, at the laboratory scale, conducted for a first time at constant solute concentration thereafter in a ‘concentration mode’, ...
