Abstract

The use of natural coagulants like Moringa Oleifera and Okra plants are receiving attention for their effectiveness in waste water treatment. The technologies involved are economical, traditional and easy to implement and ideal for rural areas. The process being biological in nature does not generate any non-treatable wastes. These processes are easy to operate and require little or no maintenance. After the treatment of both the municipal and dairy waste water samples by two natural coagulants Moringa Oleifera and Okra seeds and synthetic coagulant alum, the results show that there is a reduction in the percentage of various polluting parameters like COD, BOD, turbidity, hardness, TSS and TDS etc. In the study different quantity of coagulants doses (50 mg, 200 mg, and 500 mg) were used but it is found that increasing the amount of coagulant increases the removal but it is not proportional and significant with respect to the quantity of coagulant added. By the effect of Moringa Oleifera coagulant the reduction of turbidity, COD, BOD, hardness, TSS and TDS are found to be 61.20 %, 65.3 %, 55 %, 25 %, 69 %, and 68% respectively. There is not much effect on the pH. By the effect of Okra coagulant, the reduction in percentages of turbidity, COD, BOD, hardness, TSS, and TDS are found to be 65 %, 67 %, 56 %, 30 %,72 %, and 69 % respectively. There is no significant change in pH due to natural coagulants. By the effect of alum coagulant the reduction percentages of turbidity, COD, BOD, hardness, TSs, and TDS are found to be 59 %, 59 %, 50.98%, 67 %, and 65 % respectively. The addition of alum makes the water more acidic.
