Wastewater from slaughter houses (abattoirs) has been a problem in Nigeria. It is complex and difficult to treat. The potentials of novel Fish Bone Chito-protein (FBC) successfully extracted through de-proteinization of Fish Bone Flour (FBF) were explored for the reduction of particle load in abattoir wastewater. Extracted FBC sample was analysed via proximate analysis and instrumental characterizations viz: X-ray Fluorescence (XRF) analysis, Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectrophotoscopic Analysis (FTIR). Influences of coagulant dosage, pH, settling time and temperature were studied. The rate of particle uptake was studied using seven kinetic models. Proximate characterization of FBC revealed that it contains 24% protein, 43% carbohydrate and other components in trace values. Before treatment, abattoir wastewater contains (563 mg/L) suspended particles in excess of the national discharge standard. 92% of the particle load was removed after the coagulation treatment with 1.5g of FBC, after 35 min at pH 2, and 40 °C. BOD removal of 58% was also obtained at the same conditions. The best kinetics model selection was done between Pseudo Second Order (PSO) and fractional power (FP) kinetic model via one way statistical mean comparison using ANOVA and turkey pairwise p-values. The ANOVA p-value for pseudo second order (0.001) was found to be ˂ 0.005 (model significance alpha value). Also, the difference between the adjusted and predicted R 2 value (0.0018) was less than 0.2. Thus, pseudo second order described the kinetic data with precision. The mechanistic pathway analysis for the process particle uptake was governed by intra-particle diffusion and film/surface diffusion. The results summarized indicate that fish bones are no waste, FBF is good source of coagulant.

“…Hence, to ensure the integrity of the natural environment, several technologies have been adopted for efficient dye wastewater remediation. They include: coagulation/flocculation (Menkiti et al 2016), ozonation (Nethaji et al 2013), photocatalytic degradation (Bitenc et al 2013;Elghniji et al 2019), electrocatalytic degradation (Suhadolnik et al 2016) and adsorption (Menkiti et al 2018a, b;Ngah et al 2011).

Bamboo-based lignin (LBM) was synthesized from a simulated effluent of modified textile manufacturing process for bamboo fabrics. The efficacy of LBM modified with Al 3+ (Al-LBM) and Mn 2+ (Mn-LBM) for the remediation of crystal violet dye polluted wastewater was evaluated. Instrumental characterization of the adsorbents via Fourier transform infrared spectroscopy and scanning electron microscopy was conducted. Probable process mechanisms were postulated. The Langmuir, Sip and Freundlich isotherms were the best fit model for LBM, Al-LBM and Mn-LBM, respectively. Among the interactively competing mechanisms (confirmed by k-value and intra-particle diffusion model), the pseudofirst-order kinetic model predominated. Optimum temperature and contact time were 343 K and 30 min, respectively. The adsorption process was (based on average data) spontaneous (∆G = − 1198.69 kJ mol −1 ), endothermic (ΔH = + 86.85 kJ mol −1 ) and efficient (+ 98.11%).

In this study, the treatment of vegetable oil refinery plant condensate effluent (VORCE) having high total suspended solids (TSS) and chemical oxygen demand (COD) generated from acid oil unit was focused. The utilization of waste Brassica nigra meal (BNM) as protein flocculant in treating VORCE was explored. The B. nigra meal flocculant (BNMF) exhibited a crystalline nature, with the presence of amino and carboxyl functional groups, rendering it highly efficient (89.69% efficiency) in floc formation. Zeta potential and particle size (−5.6 mV and 240.68 nm, respectively) indicate BNMF's effectiveness in initiating floc formation. The interactive effects of pH, dosage, settling time on COD, and TSS removal were investigated using the Box–Behnken design. At an optimal pH of 6.9 and BNMF dosage of 0.77 g/L, a maximum removal of 85.38% COD and 72.56% TSS was obtained. The perikinetic theory for the coagulation–flocculation followed a second‐order rate reaction with high Kc (0.0001 L/mg min), low settling time (37.04 min), and high collision efficiency (2.703 × 1017), indicating the model's significance in achieving maximum COD and TSS removal. These findings highlight the potential use of BNMF in the treatment of VORCE, leading to circular economy by valorizing waste from mustard oil extraction and zero discharge.Practitioner points Valorization of waste Brassica nigra meal (BNM) as a potent protein flocculant Optimization for vegetable oil refinery condensate effluent (VORCE) treatment was done. Interactive effects of the process parameters were analyzed using Design expert. Perikinetic theory for VORCE treatment follows second‐order reaction rate with high Kc.
