Design of water purification polluted by heavy metal Fe with active charcoal media of palm oil and bamboo

Abstract

The design of a water purifier contaminated with heavy metal Fe has been made using activated charcoal media from palm oil shell and bamboo. The best oil palm shell activated charcoal with the following conditions: yield; 78.79%, water content; 0.50%, ash content; 10%, volatile matter content; 59.13%, bound carbon content; 41%, while the best activated bamboo charcoal with conditions: yield; 68.64%, water content; 0.50%, ash content; 8%, volatile matter content; 61.80%, bound carbon content; 38%. The experiment was started by making a sample of Kahayan river water according to data from the environmental service of Central Kalimantan province with a Fe content of 5.59 mg / L. The sample was tested using an Automic Absorption Spectrophotometer (AAS). From the data, it can be concluded that the absorption of heavy metal Fe with a length of 5 cm of activated charcoal can reduce all levels of Fe in the sample so that variations in the length of activated charcoal filling exceeding 5 cm are more effective
