Abstract

Acid mine drainage is an environmental pollutant waste arising from mining activities . Acid mine drainage ( AAT ) sulphida formed when certain minerals that exist in rocks exposed to conditions where there is water and oxygen ( as the main factor ) which causes the oxidation processes and produces water with acidic conditions . The purpose of this study is to apply the use of ceramic membranes in acid mine water treatment unit and improve the quality of the acid mine water to be safely discharged into the environment . In this study , acid mine water through the process of coagulation , filtration using a filter size of 5 lm , activated carbon and ceramic membrane . Varied parameters are operating pressure differential is 10.3 ; 15.3 ; 18.3 psi with operation time is 15 , 30 , 45 and 60 minutes . The results showed that the ceramic membrane made from clay , rice bran and iron powder with a composition of 87.5 % clay , 10 % rice bran and 2.5 % iron powder and clay composition of 77.5 % , 20 % rice bran and 2.5 % iron powder resulted in a decrease permeate flux and decrease the metal content such as Fe , Mn and Al .
