Journal ArticleDOI
Removal of congo red using activated carbon and its regeneration
TL;DR: The surfactant enhanced carbon regeneration (SECR) technique using both cationic and anionic surfactants is adopted for the regeneration of spent carbon by desorbing the dye and a kinetic model for dye desorption from the commercial activated carbon (CAC) is proposed.
Journal ArticleDOI
Nanofiltration of textile plant effluent for color removal and reduction in COD
TL;DR: In this article, a membrane-based separation process (nanofiltration, NF) is used to treat the effluent from a textile plant, which achieves a sharp reduction in chemical oxygen demand (COD) (up to 94% in cross flow cell), as the dyes are removed from the permeate.
Journal ArticleDOI
Removal of dye from wastewater using micellar-enhanced ultrafiltration and recovery of surfactant
TL;DR: In this article, the effects of surfactant-to-dye concentration ratio in the feed and the transmembrane pressure drop on permeate flux and observed retention of the dye have been studied as a function of the operating time.
Journal ArticleDOI
Impact of graphene oxide on removal of heavy metals using mixed matrix membrane
TL;DR: In this paper, a graphene oxide impregnated mixed matrix membrane (MMM) was prepared by non-solvent induced phase inversion method, which was characterized in terms of molecular weight cut-off, porosity, permeability, average pore size, pore distribution, contact angle, zeta potential and mechanical strength.
Journal ArticleDOI
Adsorption study for the removal of a basic dye: experimental and modeling.
TL;DR: An effective adsorbent is developed from saw dust and its various adsorption characteristics are studied for removing a basic dye from its aqueous solution to observe the sensitivity of the model to the variations in the model parameters.
