Abstract
This scientific study presents a knowledge on the use of Aloe Vera Gel (AVG) for the treatment of turbid water which is polluted by suspended clay.
In the study, the waste water was prepared from clay that come from Nile valley. The study covers various aspects of the treatment process, including the effectiveness of Aloe Vera in removing pollutants from wastewater, and the optimization of the treatment process. Aloe Vera Gel was extracted from Aloe Vera leaves and the gel is blended to get it in a semi-liquid form. It is applied with different doses for treating the clay suspension. A noticeable improvement in % reduction in turbidity is obtained due to the use of AVG as a natural flocculent.
The study shows that AVG can be used as a natural coagulant for the treatment of wastewater, and it can effectively remove pollutants such as color and turbidity. In this research we used (0, 2, 4, 6, 8 ml/l) AVG and the optimum dosage of AVG for the treatment of turbid wastewater was found to be 6 ml/l of suspension. The effect of particle size of clay on turbidity removal is studied. (200, 400, 600 µm) were used. Clay suspension with 600 µm gives the lowest turbidity (40 NTU),
Clay suspensions of two different concentrations, 10 and 50 g of clay/l were tested. For providing a means to predict the AVG required to accomplish a specified clarification process, the ratio of AVG/Clay in the suspension is examined throughout the experimental work. The best ratio was found to be 6/10 and it results in the minimum residual turbidity of 40 NTU and percentage reduction in turbidity of 89 %; when treating a clay suspension of 10 g Clay/l.
Thus, the research presented in this study provides valuable insights into the use of natural materials for turbid wastewater treatment and contributes to the development of sustainable solutions for environmental challenges.
