“…Low zeta potential ensures recession or total double-layer collapse to actualize Table 5. The discrepancies occurring in kinetic parameters could be attributed to interplay between van der Waals and hydrodynamic forces, which reduces by factor of 2 the correlation between experimental and theoretical values [19,24,40,41].…”

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.

“…Other components of TFS are calcium carbonate, entrained protein and color pigment. In addition, TFS can also be used for construction and as a source of animal feed [19]. On deacetylation of TFS, it converts to chitosan that constitutes the active coagulation ingredient [11].…”

A study was carried out to estimate the populations of the periwinkles Tympanotonus fuscatus and Pachymelania aurita at the Rumuolumeni mangrove swamp creek in the Nigeria, Niger Delta sub-region. Weekly sampling of the gastropods was done and the capture mark-releaserecapture method was used for the population estimation. The Lincoln index was used for the calculation of the total population. The results indicated that T. fuscatus was more abundant in the area than P. aurita. It was opined that since P. aurita was more susceptible to pollution than T. fuscatus, its reduced population density could be attributed to the activities of oil companies operating in the Niger Delta region and their attendant pollution of the brackish water ecosystem, in addition to reproductive failure resulting from climate change.
