While, optimized setting is at pH 5, concentration of Fe3+ is at 50 mg/L and concentration of biopolymer is at 15 mg/L for turbidity removal of 99.32%. pH, dosage of Fe3+ and biopolymer significantly affect the turbidity removal in coagulation process with p-value < 0.05. Influence of pH, dosage of Fe3+ and biopolymer were studied in synthetic kaolin and agricultural wastewater using factorial design. The morphologies study depicted that the addition of biopolymer produced a more compact and larger structure of the settled sludge. Whilst, zeta potential was around −16 mV, describing its anionic nature. FTIR spectra results indicated the biopolymer was assigned to band peaks at for hydroxyl, carboxyl groups. functional group, zeta potential and surface floc morphology. ![]() ![]() Various physico-chemical characterisation studies were conducted i.e. This study aims to study the possibility and mechanism of biopolymer extracted from garden cress (Lepidium Sativum sp.) seed as natural coagulant aid in a point source agriculture wastewater discharge. Abstract: Agricultural anthropogenic processes have resulted in high turbidity to nearby river water. ![]()
