Optimization of sustainable chitosan/Moringa. oleifera as coagulant aid for the treatment of synthetic turbid water – A systemic study

Abstract

In this study, acid treated carbonized chitosan@ Moringa. oleifera (ACCM) have proven to be better coagulant for the treatment of synthetic turbid water from the wastewater system. The compound exhibit better coagulation capability, low leaching level and higher adsorption ability. The biological-based coagulants such as Moringa. oleifera (M. oleifera) owes more advantageous over synthetic materials on wastewater treatment due to its nature of less toxicity and bio-degradability nature of coagulants. It produces a lesser amount of sludge formation with low content of metals. The occurrence of main elements such as oxygen and carbon on M. oleifera promotes the efficiency of coagulant in the coagulation process. The charge of proteins exerts neutralization mechanism due to sulfur (S), magnesium (Mg), calcium (Ca), and potassium (K) elements present in the ACCM. Therefore, the charge of the turbid water has found negative, further turned to a neutral one. The higher efficiency of the turbid coagulation of the coagulant is confirmed via neutralization mechanism. The wastewater processing using bio-based coagulants mainly composed of molecular linking, adsorption and charge harmonising. Hence, the present work aims to investigate the removal of turbidity from synthetic turbid water, brine solution and contaminated groundwater with more turbidity using ACCM based coagulants.
