ABSTRACT
In this Project work, the effect of the performance of powdered moringa seed as a coagulant for water treatment was aimed and the specific objectives were to fabricate a jar tester, study the effect of selected parameters such as the effect of speed, dose and time on the coagulation process, analyze the chemical composition of moringa seed, and evaluate the performance of the powdered moringa seed as coagulant in reduction of total suspended solid in turbid water. This was done by conducting laboratory test for total suspended solids in turbid water. Total suspended solids in turbid water sample were measured before and after the Jar testing using varying doses of moringa oleifera extracts by using portable instruments. The experiments were carried out with coagulant dosage of 20 ml, 50 ml and 100 ml respectively. Total dissolved solids removal efficiency of moringa seed obtained from this study was 76.47% at a dosage of 0.8mg/l. Moringa seed thus exhibited high efficiency in removing Total Suspended Solids. Also, Regression test was done using Excel software and Data Fit software to obtain an equation to study the relationship between selected parameters such as the effect of speed, dose and time on the coagulation process and it was concluded from the equation obtained that the total suspended solid in turbid water produced was reduced best at the reliability (R2) value gotten as 0.3644 which indicates that powdered moringa seed when used as a coagulant in removal of total suspended solids will be 36.44% efficient.
