An integrated membrane process for treatment of effluents from food additive manufacturing was designed and evaluated on a laboratory scale. The principal focus water recovery with the possibility its reuse as potable water. industrial effluent presented high content dyes salts. It red in color brine characteristics. whole fed into continuous flow. steps are follows: sedimentation (S), adsorption by activated carbon (AC), ion exchange using resins (IEXR), reverse osmosis (RO) (S-AC-IEXR-RO)....
The sorption processes of red 5 (R5) and yellow (Y5) dyes by iron modified sodium bentonite in aqueous solutions was evaluated. clay prepared, conditioned characterized. did not remove any either dye. kinetics isotherms R5 Y5 were determined. maximum removal percentages achieved 97% 98% for Y5, respectively, a contact time 72 h; the experimental data best adjusted to Ho model. both Langmuir model adsorption capacities 11.26 mg/g 5.28 respectively. These results indicate that have high...
The adsorption of red-2 and yellow-2 dyes from aqueous solution was evaluated using both Na Zn zeolitic materials in the absence presence hydrogen peroxide. adsorbents were characterized by scanning electron microscopy, X-ray diffraction, their specific surface areas determined. Sorption kinetic isotherms, peroxide, behavior Na-zeolitic tuff H2O2 similar. experimental data best adjusted to model Lagergren yellow-6 pseudo-second-order indicating chemisorption. isotherms showed low capacities,...
The adsorption of the calyx extract Hibiscus sabdariffa L. (a natural pigment) onto cassava starch (CS) was evaluated in order to develop a simple and efficient process separation obtain biocomposite with antioxidant properties.The diffusion mechanism anthocyanin on adsorbent analyzed, considering pH, contact time dosage.Dye equilibrium reached after 12 h time, it described by pseudo-secondorder kinetic intra-particle models.Adsorption data were treated Langmuir, Temkin Freundlich isotherms...
