Tympanotonos fuscatus shell (T. fuscatus shell), an abundant eco-friendly waste was used as a precursor for the production of Tympanotonos fuscatus coagulant (TFC) for the purification of paint effluent (PE). Tympanotonos fuscatus shells (TFS) are of crustacean origin consisting mainly of chitin, calcium carbonate, entrained protein and other organic matrixes. Influence of pH, dosage and settling time on treatment efficiency was studied. Scanning electron microscopic, Fourier transform infra red, X-ray diffraction and differential scanning calorimetric/thermogravimetric analyses were carried out to investigate, respectively, the surface morphology, functional group, crystalline/lattice structure and thermal stability of TFS, TFC and settled sludge after treatment. The PE was optimally treated at 2 g/L TFC dosage, pH 5 and 97 % efficiency. Results indicated that TFC could be an efficient treatment agent for PE at the conditions of the experiment.

“…Paint effluent (PE) contributes to this pollution. PE is turbid and contains highly toxic compounds that harm humans, fishes and contaminates the food chain if drained into soil [1,2]. Thus, the treatment and safe disposal of PE become vital for environmental conservation.…”

ABSTRACT. Adsorptive study of paint effluent coagulation using T. fuscatus coagulant (TFC) is investigated. Effects of pH, dose, time, and temperature were investigated. Functional group, crystalline, morphology and thermal characteristics of samples were determined. Equilibrium data were analysed by Langmuir, Freundlich, Temkin, Frumkin, and Dubinin-Radushkevich (D-R) isotherms. Kinetic data were fitted to reversible first order, pseudo-first-order, pseudo-second-order, Elovich, intra-particle diffusion and Boyd kinetic models. Process Gibbs free energy (∆G°), enthalpy (∆H°) and the entropy (∆S°) were evaluated. The process was best described by Langmuir isotherm (R 2 > 0.99; X 2 ˂ 0.6; SSE ˂ 0.7). Pseudo second order best fitted the kinetic data. The process was spontaneous, feasible and endothermic. 97% optimal removal was achieved at pH 5. Tympanotonos fuscatus extract has potential for application as an effective coagulant while showing significant component of adsorptive phenomenon
