All streams, particularly household wastewater, contain both dissolved and suspended particles. The goal of this research was to see how effective Moringa oleifera (MO) as a natural coagulant, is in removing different parameters of sullage collected from the college canteen. Moringa oleifera was used to treat sullage in various dosages, such as 50 mg, 100 mg, 150 mg and 200 mg. The effects of Moringa oleifera treatment on parameters, such as BOD, COD, total solids, turbidity, nitrate, phosphate and the microbiological activity of sullage were studied before and after treatments. At maximal dosage, the bark of Moringa oleifera was able to efficiently remove BOD, COD, phosphate and nitrate in a range of 40±0.81 mg/L, 384±0.66 mg/L, 4.30±0.52 mg/L and 9.3±0.68 mg/L, respectively compared to Moringa seeds in range of 80±0.61 mg/L, 448±0.30 mg/L, 3.3±0.63 mg/L and 11.3±0.61 mg/L. For BOD and COD absorption, oil extracted Moringa seeds was more efficient than Moringa seeds, reaching 60 mg/L and 416 mg/L, respectively. Using Moringa oleifera seeds and bark, microbial activity in the sullage sample were reduced to the greatest extent possible. After the treatment, there was no change in the pH or conductivity.
