Abstract

In the present study experiments were conducted inthe lab to investigate the efficiency of stock solutions obtained from the herbs of Moringa Oleifera (Drum sticks) , Okra gum , and the mucilage isolated from the dry flowers of C.Procera as flocculent for the treatment of turbid water samples containing synthetic turbidity caused by clay materials. Jar test experiments were carried out for high(250NTU and 500NTU), low levels (15NTU,30NTU and 50 NTU) and medium level(100NTU) of turbidity with the flocculent dosages of 0mg/l 2.5mg/l ,5.0mg/l ,7.5mg/l ,10.0mg/l ,12.5mg/l ,15.0mg/l for Moringa Oleifera , Okra and C.Procera. The results have been compared with the results of alum. The supernatant turbidities obtained from this phase of the study were > 5 NTU. In the next phase again jar tests results were obtained from adding nearly 50% optimum dose of the natural coagulant was kept as constant and dosage of alum was varied. The supernatant turbidities obtained from this study were nearly equal to 5 NTU. (Guide line value recommended by WHO).
