Design Of A New Layered Composite Membrane Based On A Physical Copolymer (PSU / PEI / PPc) Supported By A Tri-Component Support (PA6 / Fiberglass / PA6). Application of Ultrafiltration Baths Based On Azoic and Antraquinonique Dyes.

An asymmetric porous tri-component support coated with a thin hydrophilic layer and active physical copolymer (Polyetherimide, Polysulfone and filled Polypropylene by 80% TiO2) noted (PEI / PSU / PPc) was used to synthesize d a new composite membrane tri-component collodion for ultrafiltration. The prepared membrane was characterized by scanning electron microscope (SEM) and the mechanical property by a tensile testing machine. The ultrafiltration process was used to treat a family of reactive dyes (blue and orange 49 16) from synthetic aqueous solutions and for raw textile effluents supplied from the rinsing / padding baths of the textile industry. The flow and the selectivity of the membrane during are directly related to the thickness of the active film, the pore size and the molecular weight of the reactive dye. The color retention performance, the chemical oxygen demand (COD) and conductivity were evaluated to determine the separating performance of the membrane. The conductivity rate is > 67%, the high COD and the color retention is (> 86%) were obtained by this composite membrane vis-à-vis the two dyes investigated in an alkaline medium at the upstream and downstream of the membrane

Remediation of dyes in textile effluent by membrane based treatment techniques: A critical review

The most important industry implicated in our exposed population is the textile industry arena because of their undeniable contributions to basic human needs satisfaction and to the world economy. These industries are utilizing higher volume of water that finally results in an abundant wastewater generation; these are the major water polluting sources of ecosystem.The present paper provides a review of the management of the membrane technology towards textile effluent treatment. The concept of water reuse is also catching on quickly through membrane based techniques, including the prospect of turning textile sewage into the clarified water. We are using the microfiltration, ultrafiltration, nanofiltration and reverse osmosis.
