The transport coefficients, namely, hindered coefficient for diffusion and convection as well as steric ...

The model was based on simultaneous solution of solution-diffusion model, film theory and osmotic pressure model. The osmotic pressure model was modified by incorporating ...

In Scheme 1, advanced oxidation was followed by NF and in Scheme 2, two-step NF was employed. In Scheme 1, dye concentrations fell below 1 mg/l. In Scheme 2, two-step NF results in permeate concentration less than 1 mg/l of dyes. Salt recovery is almost 96% in Scheme 1, which was 3% more than in Scheme 2. COD values of finally treated effluent were well within permissible limit (250 mg/l) in the range of 61?68 mg/l.

Effects of concentration of various reagents on the degradation of dye were explored during an advanced oxidation process. It was found that ferrous concentration plays a major role in dye decomposition. Rate of dye decomposition is faster with an increase in ferrous sulfate concentration compared to the increase in hydrogen peroxide concentration. A detailed kinetic model was proposed. Profiles for eosin, hydrogen peroxide and various intermediates were also generated. The rate constant of the reaction of eosin with a hydroxyl radical was found to be of the order of 109 l/mol.s.

Due to the ionic character of the dye, fixed charges in the membrane pores affect the permeation of the dye. Two transport coefficients, ...
