Abstract

The use of conventional metal-based coagulant for removal of suspended solid from drinking and waste water is known to have elongated effect on human health. This problem had hitherto lead to new grounds through use of alternative natural coagulant which does not generate chemical residue in its effluent. The use of natural coagulants of plant origin signifies a fundamental breakthrough in sustainable environmental water sanitation. Natural coagulant has helped improve the sequential processes of water and wastewater treatment for underdeveloped communities. Even though promising results have been recorded from some existing/discovered natural coagulant, the need to intensify effort in exploring and or discovering new plant based natural coagulant is necessary to sustain the environment through provision of good quality drinking water for sustaining livelihoods of human well-being and socioeconomic growth; as well as ensuring protection against pollution and water related diseases. This study examined the potential of water melon seed as coagulant in water and wastewater treatment.
