“…As shown in Figure 7, the second-highest dose of Carica papaya seeds at a concentration of 1.5 M NaCl reduced COD by 20.95%, while a dose of 0.5 mL at a concentration of 0.5 M had the least effect, removing only 0.42%. Carica papaya seed can reduce COD value because Carica papaya seed contains glutathione (GSH) [34,35]. GSH has been associated with the defense response to biotic stress [36].…”

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.

Fresh water is already scarce in the world, especially in the Middle East (ME). Desalination industry is the main supplier of the potable water to the municipalities in the ME region. It is well known the high cost of a liter of water produced by the desalination process. Unfortunately, car-washing service consumes substantial amount of this desalinated water. This paper describes a filtration system designed and tested for treatment and reuse of the wastewater generated in car-washing stations. The filtration system assembled from two filters: (1) sand and gravel mix, and (2) activated carbon. The paper is an extension of work originally presented in ASET conference in Dubai. The quality of the effluent (treated wastewater) was investigated and determined in Dubai central laboratories. Wastewater samples were grabbed from different car service stations. Representative samples were prepared and the concentrations of the following parameters were measured in each sample of the effluent: (1) Biological oxygen demand (BOD), (2) Chemical oxygen demand (COD), (3) Total dissolved solids (TDS), (4) Total suspended solids (TSS), and (5) Oil and grease (OG). The results show that the filter system removes the BOD and COD at an efficiency as high as 97.5%, the TSS at 90%, and the TDS and OG at 85.5%. In general, the quality of the effluent was found to fall within the standards set by Dubai regulatory authorities. Further research is recommended to enhance the filtration system performance and make it commercially applicable.
