ABSORPTION MODEL OF AIR POLLUTERS AT INDUSTRIAL STACK USING COCONUT SHELL

In minimizing emitted air pollutants, it is necessary to modify it by creating a pollutant absorber. Modifications are made in this research is by using coconut shell charcoal mounted on the end of industrial stack. The coconut shell used in absorbing air pollutants, before leaving the stack, while to keep the charcoal from burning, a condensation system is performed. The results showed that the concentration of SO2 and dust contaminants decreased by 34% and 42%, respectively. The decrease in pollutant concentrations indicates that coconut shell charcoal used as a pollutant absorbent tool emitted from the industry. Among the two types of pollutants tested, it appears that coconut shell is more effective to absorb pollutants of dust. Therefore, other modifications are needed, so that the coconut shell can optimally absorb all types of air pollutants.
