Valorization of Dairy Sludge in Water Treatment: Assessment of Biosorption of an Industrial Dye (A-BG) | Chapter 06 | Emerging Challenges in Environment and Earth Science Vol. 2

 Today, pollution control is a top priority. Industrial wastewater, particularly that from the textile and paper sectors, can contain a wide range of organic micro contaminants, including dyes. The environment is seriously harmed by the lack of treatment of these fluids. It is preferable to treat this water before it is discharged in order to limit the amount of pollution it contains.

Biosorption can be thought of as a cost-effective and efficient alternative to the numerous existing micropollution remediation technologies.

The effects of initial pH solution, biosorbent dose, biosorbent particle diameter, and initial dye ion concentration on biosorption were investigated. Batch experiments were used to measure these parameters. With increasing dye concentration, equilibrium absorption increased, reaching a maximum sorption capacity of 178.6 mg g-1. The adsorption equilibrium data were analysed using model equations such as Langmuir and Freundlich isotherms, with the first isotherm model providing the best matches to the experimental data. To evaluate the biosorbent, scanning electron microscopy and energy-dispersive X-ray (SEM-EDX), Brunauer–Emett–Teller (BET), Fourier transform infrared analysis (FTIR), and microbiological characterization were used. Kinetic models such as pseudo-second-order and intra particle diffusion were used to characterise the adsorption mechanism.

The proposed study involves assessing the ability of a dairy sludge to fix a textile dye, A-BG (Astrazon brilliant), in an aqueous solution in a batch method.

The use of dairy sludge as an adsorbent for the removal of harmful cationic dyes was studied.
