Description :
There are several pollutants that can harm our environment. Oil and grease are one of the examples of a pollutant that can cause a severe environmental problem. The highest concentration of oil and grease inside the sewer system can cause the sewer to clog that can lead to overflow. It can affect not only to the environment but can also affecting our health. There are various methods of oil and grease removal that one of the examples is by using adsorption method. This method commonly uses activated carbon that is one of the effective adsorbents. Although effective, the cost for activated carbon is expensive thus a study was conducted by using agricultural residues as alternative adsorbents for oil and grease removal. In the present study, we used neem bark as an adsorbent for the removal of oil and grease from industrial wastewater. Optimization of adsorbent dose, optimization of pH, optimization of contact time and optimization of settling time are the parameter used for performance studies, to see the ability of adsorbents in removing oil and grease.
