Abstract
Vehicle washing service is a commercial activities used detergent as supporting material to clean vehicles. The vehicle washing waste decrease the ground water and surface water quality. Water savings are needed trough recycling and fixing water quality. This study aims to determine the best flow direction in reducing the turbidity, surfactants, and COD concentration contained in the wastewater using an activated carbon filter with the filter diameter 10 cm, the activated carbon height 90 cm and the activated carbon grain in size >2 mm. The variation used in these research is: flow direction (bottom to top, top to bottom in submerged condition, and top to bottom without submerged condition); initial surfactants concentrations; and flow rate. The results showed that the best turbidity removal occur in the up to down direction in all discharge and concentrations variations which succeeded in removing turbidity 100%. The best surfactants removal occurs in the bottom to top direction with a discharge 0.0088 L/s which removed the surfactants 99.92%. The best COD removal occur in the top to down direction with submerged condition in discharge 0.0147 L/s which removed COD 67.45%. Each flow direction has difference mechanism and process to removal parameters.
