“…The XRD diffractograms show the presence of minerals such as Freedite (Pb 8 Cu(AsO 3 ) 2 O 3 Cl 5 ) and Jalpaite (Ag 3 CuS 2 ). The presence of silver (Ag), copper (Cu), and Cl (chlorine) elicit anti-bacterial characteristics of F. benghalensis, which is further validated in the anti-bacterial study [9,47,48].…”

“…According to literature, hydrophobic fractions (humic acid and fulvic acid) of NOM have a prominent contribution to dissolved organic carbon (DOC) in water. These DOC in water will form disinfectant by-products (DBPs) such as trihalomethanes (THMs), haloacetonitriles (HAN S ), haloketones (HKs), chloral hydrate (CH), chloropicrin (CP), and halo acetic acid (HAA) in chlorinated water [8][9][10].…”

Conventional coagulation techniques have shown inefficacy for the removal of DBPs precursor i.e. hydrophobic NOM. The present study has used a bio-flocculant named Ficus benghalensis to enhance the coagulation activity of alum for the removal of hydrophobic NOM. The coagulation activity of the augmented treatment (Alum-F. benghalensis) system was validated using spectroscopic analysis. The augmented system had shown an increment in DOC and A254 removal by ~30% and ~16%, respectively. ASI and A272 had shown a continual decrease (from 0.12 to 0.08 and 0.46 to 0.23, respectively) for the augmented system. Chlorine demand was found lesser for the augmented system (1.4 mg/L) compared to alum (1.55 mg/L) only. The augmented system had shown a drastic reduction (from 0.1459 to 0.0638) in the value of (-∆A272), which is directly related to the reduction in THMFP. The combined effects of sweep coagulation and charge neutralization were the responsible mechanisms for the augmented coagulation system. The noteworthy anti-bacterial activity of F. benghalensis was observed due to the presence of silver, copper, and traces of chlorine in its structure. Thus, the proposed augmented coagulation system can be used to remove the hydrophobic NOM from the water.
