ABSTRACT

The study assessed the potential of using Hibiscus Sabdariffa seed extract (HSSE) as a coagulant in water treatment. The seeds were winnowed, ground and sieved to175µm. A stock solution was prepared from the seed powder and Jar test was run on surface water samples obtained from Challawa Gorge dam and Kano River to determine the required dose of HSSE to meet acceptable drinking water standard. The pH and turbidity of both raw and treated water were noted. The pH of treated water with HSSE was within the range of 6.2-7.9. The study also revealed that Hibiscus Sabdariffa seed extract was relatively good in turbidity removal with percentage efficiency of 62.80% and performs better in highly turbid water at an optimum of 1.5 mg/l.
