Effectiveness of Moringa Oleifera and Blends of Both Alum and Moringa as Coagulant in the Treatment of Dairy Wastewater

Abstract Food processing industries can cause some serious problems for the environment through discharge of wastewater. There is little information on effectiveness Moringa Oleifera (MO) seeds treatment dairy wastewater, this study therefore evaluated MO and blends both alum in coagulation diary Wastewater collected from oriental food industry limited was kept a 10L capacity plastic container covered using black polyethene bag containing ice blocks conveyed to laboratory where it refrigerator. Six different beakers (Nos 0-5) were filled with 200 mL wastewater doses selected coagulant (alum, blend both) added six ranging 0-10mL at an increment 2mL treat The beaker number 0 served as control (no dosage) whole process applied coagulants. This test carried out settling time 1 hour. physicochemical characteristics treated determined standard methods. Data analyzed descriptive statistics ANOVA. analysis indicated that raw had values 932 NTU, 1690.99 mg/L, 7.2 685 mg/L turbidity, BOD, pH TSS respectively. results revealed optimum dosage 10mL 1hr respectively, removal efficiencies 88.76, 82.63 86.42 % obtained moringa alum, three types coagulants did not have much effects BOD there no significant differences values. use effective
