Improving filtrate quality using agrobased materials as coagulant aid<br />

Abstract<br />
In <strong>the</strong> present study, an evaluation of agrobased materials (ABM) as a coagulant aid in conjunction<br />
with alum has been conducted to determine <strong>the</strong>ir efficacy in water treatment. The agrobased<br />
materials evaluated are Surjana seed (Moringa oleifera), Nirmali seed (<strong>Strychnos</strong> potatorum) and<br />
maize (Zeemays). Experiments have been conducted simulating a conventional water treatment train<br />
consisting of coagulation-flocculation-settling and granular media filtration. Emphasis has been<br />
given to <strong>the</strong> filtration aspect of <strong>the</strong> treatment train using syn<strong>the</strong>tic turbid water. The filter<br />
per<strong>for</strong>mance was defined by water quality and head loss development across <strong>the</strong> filter bed. When<br />
Nirmali seed or maize was used as a coagulant aid, <strong>the</strong> alum dose required was 25 and 15 mg/L,<br />
respectively, and <strong>the</strong> filtrate turbidity achieved was less than 0.2 NTU, whereas alum alone with a<br />
dose of 45 mg/L achieved filtrate turbidity levels higher than 1 NTU. Thus, <strong>the</strong> use of ABM<br />
improved <strong>the</strong> filtrate quality. Head loss in filter with Surjana seed and Maize as coagulant aids was<br />
comparable to that of alum alone, whereas it was higher when Nirmali seed was used as a coagulant<br />
