Evaluating the Water Treatment Potential of Hibiscus sabdariffa Extracts

Authors: Jones AN

DOI Info: N/A


This study investigated the use of sabdariffa crude extract (SCE) in water treatment using jar test experiments. In the work reported here, varying coagulant doses and pH ranges were tested using synthetic turbid water. The results show that SCE achieved 94 and 85% turbidity removal in 200 and 50 NTU water samples respectively. Similarly, the heat-treated and stored SCE samples recorded 96% and 97% turbidity removal respectively. Additionally, SCE was found to be thermo-stable at various temperature tested which showed improved performance at the end of the treatment process. Furthermore, the pH of the final treated water remained largely unaffected due to buffer effect (i.e. buffer capacity of 0.029) of the protein. Therefore, Hibiscus sabdariffa seed could be a potential water treatment material in developing countries where access to clean drinking water is still a major challenge.
