Comparison of Zea Mays, Moringa Oleifera and Carica Papaya in Water Coagulation

Water coagulation using locally available materials is a way to avoid the stress and hazards involved in using chemical coagulants. Moringa oleifera, Carica papaya and Zea mays seeds are known to possess coagulation properties but its difference and efficiency of active duration is achieved in this work. The seeds were prepared in solutions which were added to a turbid runoff water collected from ESUT. 3ml, 5ml and 10ml of the seed's solution was introduced to 400ml of turbid water. It was observed that after 24 hours, the runoff water treated with 5ml of Moringa oleifera seed solution had the lowest turbidity value of 3.38 NTU and 10ml of Carica papaya had the highest turbidity of 7.1 NTU. After 7 days, it was observed that the runoff water treated with 5ml of Moringa oleifera seed solution had the lowest turbidity value of 5.1 NTU and Carica papaya had the highest turbidity value of 6.85. After 14 days, it was observed that the water treated with 3ml of Moringa oleifera seed solution had the highest turbidity value and the water treated with 10ml of Zea mays had the lowest turbidity value of 2.85. These observation shows that Zea mays has the longest effect on coagulation while Moringa oleifera had the fastest effect on coagulation for the volume of water used.
