This study aims to assess the efficacy of Carica papaya-dried seeds as a natural coagulant in the wastewater treatment process. Using natural coagulants in water treatment provides a safer and more sustainable method. Insufficient research in this field hinders a thorough comprehension of the ideal circumstances, dosage, and potential impacts of Carica papaya dry seed coagulation on pollutant elimination in wastewater. Therefore, the investigation of the extraction procedure for coagulants derived from dried Carica papaya seeds is essential to establish a reliable and efficient method suitable for use in wastewater treatment facilities. The number of experiments were conducted to accomplish the objective of this study. The experiment utilised textile effluent from an industrial area in Parit Raja, Johor as the wastewater sample. The Carica papaya seeds were ground into a powder and then mixed with Sodium Chloride (NaCl) and distilled water to create a coagulant solution. COD, turbidity, pH, and settling depth were measured to assess the effectiveness of Carica papaya seeds in treating the effluent sample. At a Carica papaya seed coagulant dosage of 2.0 mL with a NaCl concentration of 1.5 M, the optimal COD reduction and turbidity removal efficacy were at 20.95 % and 23.00 %, respectively. This study shows that among 5 different concentration solvent, 1.5M NaCl is most optimum concentration condition demonstrated. Moreover, the research represents the significant potential of Carica papaya seed powder as a natural coagulant for treating wastewater that contains textile colouring agents. In conclusion, the research demonstrated that dried Carica papaya seeds possess the potential to serve as a natural coagulant in wastewater treatment procedures, thereby presenting a safer and more ecologically sustainable alternative. This study offers insights into the ideal conditions for utilising dried Carica papaya seeds as a natural coagulant for treating wastewater that contains textile colouring agents.

“…The best advantages of Moringa oleifera are: availability and low cost of production, possibility of using its seeds and shells, and, later, of using the sludge generated by the treatment, since it is biodegradable and can be used as a fertilizer (Alves et al, 2010;Keerthi et al, 2022;Reddy et al, 2010;Vieira et al, 2010). Because of its characteristics MO has been widely used in different types of water treatment alone or combined with other types of coagulants or process to remove turbidity (Lo Monaco et al, 2010;De Paula et al, 2014;Muniz et al, 2015;De Paula et al, 2016;Mateus et al, 2017;De Paula et al, 2018;Valverde et al, 2018;Ribeiro et al, 2019;Assunção et al, 2020).…”

Contamination of water resources by industrial effluents represents a major environmental problem and, in Brazil, the dairy industry is one of the main causes of these problems. The composition of its effluent has a high amount of organic matter and nutrients and, therefore, it is necessary to treat them before disposal. This study aimed to optimize the treatment of synthetic dairy effluents, simulating the coagulation/flocculation process, through the application of a natural coagulant based on Moringa oleifera seed extract, using the Rotational Central Composite Design associated with the Surface Methodology response (MSR). The independent variables in the project were the fast and slow mixing times, the coagulant dosage and the concentration of pollutants. A mathematical model was established with an R² of 0.6, in which the significance of the pollutant concentration and coagulant dosage was proven. From the re-parameterization of the mathematical model, considering only these two variables, an adjustment of 74% was obtained. As a result, a removal efficiency of 94.9% of turbidity was obtained, demonstrating – in the first approximation analysis – a strong result for the use of a natural coagulant to remove turbidity from dairy effluents.
