Due to the presence of contaminants in wastewater, the importance of wastewater treatment using inexpensive sorbents is very important. This study describes the production of activated carbon from the bark of the VAGAI TREE (Albizia lebbeck) and the feasibility of adsorption and flocculation in domestic wastewater treatment. Plants are abundant in tropical regions. Activated charcoal is dried and powdered tree bark. It was washed with an acetic acid solution to decolorize and held in a muffle furnace at 650° C. to dry again. The effect of activation temperature of activated carbon was studied. We found that the continuous release of volatiles and combustion of carbon via weak carbon-CO2 oxidation resulted in significant weight loss during the activation process, resulting in an increase in solid density and a decrease in bulk density. I was. The adsorption properties of Vagai bark were studied in a batch system by considering the influence of various parameters such as contact time, initial concentration, pH, temperature, stirring speed and absorption amount. Adsorption was pH dependent, with maximum adsorption capacity observed at pH 4.5–5.8. Haze and dissolved solids removal efficiencies are 98% and 97%, respectively. The results showed that the low-cost biosorbent was effective in removing contaminants in wastewater.
