Eco-friendly Treatment of Industrial Wastewater with Local Raw Clay
Industrial and agricultural activities generate wastewater rich in organic pollutants and threaten water resources. The city of Ouagadougou is strongly confronted with this problem of wastewater discharged by some pollution sources, such as industries. This work aims to use ecological and low-cost purification methods to remove organic pollutants from industrial wastewater using natural clay from Burkina Faso. The results were obtained by the batch mode experiment. With 1 g of clay, at free pH of wastewater, the results showed that the rise in temperature leads to an increase in chemical oxygen demand (COD) and biochemical oxygen demand (BOD5) removal. This effect is very remarkable from 35 °C with removal rates approaching 100% for BOD5 and 50% for COD. In addition, the study of the raw clay dosage effect from 1 to 5 g per 100 mL of wastewater showed an increase of the raw clay dosage removal rates in COD and BOD5 to above 70% for 5 g of adsorbent. The maximum removal rate achieved is 70% for COD and 98% for BOD5 with the optimum temperature of 37 °C. The optimum dosage would be 5 g per 100 mL of wastewater with a contact time of 20 h.
