This study presents, the synthesis of microwave‐assisted biodegradable polyacrylamide grafted tragacanth gum (Tr‐g‐PAM), which was utilized as a bioflocculant to treat textile effluent and compared against the conventional flocculant. The reaction parameters for maximal grafting were optimized by varying the reaction factors. The grafting of acrylamide onto the backbone of Tragacanth gum was confirmed by FTIR, XRD, TGA, and SEM–EDX studies. Swelling studies were performed in deionized water and different salts. Tr‐g‐PAM exhibited pH and temperature‐dependent swelling behavior. Biodegradation studies of the graft copolymer were carried out by the soil composting method. Tr‐g‐PAM showed 91.54% degradation within 60 days, compared to Tragacanth, which degraded within 15 days. SEM techniques were used to describe various phases of biodegradation. Flocculation performances of the graft copolymers were evaluated in simulated colloidal wastewater. Influencing variables such as bioflocculant dosage, pH, and flocculation mixing speed were examined. The maximum decolorization at the optimum pH of 6 and 120 mg/L dosage was found to be 91.8% and 88.5% for Tr‐g‐PAM and Tragacanth. In conclusion, a biodegradable Tr‐g‐PAM with better flocculation efficiency than that of Tragacanth and other commercial flocculants would be a promising choice as an eco‐friendly adsorbent for the removal of contaminants from water resources.

“…In the coagulation/flocculation process, the mixing speed of the bio‐flocculation was an essential factor. A range of mixing rates (30–70 r/min) was evaluated during the flocculation under the optimal experimental conditions, which included a bioflocculant dosage of 120 mg/L, pH of 6, and a mixing flocculation speed of 200 r/min 40 …”

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.
