With rapid increase in population, industrial development and water usage, faecal pollution of drinking water is creating enormous public health hazards like water born diseases due to careless disposal of sewage water [1]. Drainage of sewage water without treatment and its use for irrigation purpose are possible ways of heavy metals accumulation in plants food chain [1]; [2]. Several conventional methods are used for waste water treatment including coagulation-flocculation followed by sedimentation, filtration, precipitation, ion exchange resins and reverse osmosis before its distribution to consumers [3]; [4]. Many inorganic coagulants, synthetic inorganic polymer and naturally occurring coagulants are also widely used in conventional water treatment processes [4]. Nonetheless, use of ploy ammonium chloride, poly alumnium silico sulphate and inorganic alum salt is most common [5]; [6]; [7]. And use of aluminium containing coagulants is expensive and synthetic organic polymers have strong carcinogenic properties [8]; [9]. Further, aluminium is causative agent of neurological disorder presenile dementia and alum itself may induce Alzheimer’s disease [10] and have low coagulation efficiency when react with natural alkalinity in water leading to pH reduction [11]. Moringa oleifera Lam. is widely adapted in tropic and subtropics and cultivated in developing world. Its seeds are used as organic natural polymer containing polypeptide with cationic polyelectrolyte properties good for softening hard water by adsorption [ 12]. According to Ndabigengesere et al [ 13], aqueous extract of Moringa oleifera Lam. seeds contain stable and water soluble dimeric proteins active in coagulation. Many studies highlight the efficiency of Moringa oleifera seed extract as coagulant [ 14] used in coagulation of model turbid water [ 12], quality of treated water, as primary coagulant and in conjunction with alum for coagulation of river water [ 11]. Moringa is native to Indo-Pak and its use as multipurpose tree is rapidly increasing [ 15]. Further, with increasing urbanization, industrialization and depletion of ground water resources, sewage wastewater treatment is widely propagating from small to industrial scale for domestic purposes [ 2]. Very few studies are available on usage of Moringa oleifera seed powder or its aqueous extract as alternative coagulant or its conjunctive use with alum in wastewater treatment. The present study therefore investigated the potential of Moringa oleifera seed powder or its aqueous extract on pH, electrical conductivity (EC) to minimize heavy metals load of sewage waste water.
