ABSTRACT The potentials of Moringa oleifera seeds and Aluminium Sulphate as coagulants for the treatment of water samples from Usuma River Abuja was carried out. The physicochemical parameters investigated were the Turbidity (in NTU), Total Dissolved Solids (in mg/l), Conductivity (in μS), and Salinity (in ppm). For the water treatment with Alum, the standard municipal water treatment dosing of 360 mg/l was used. For the treatment with the natura...
