Abstract

The construction of hotels is so rapid today will bring a significant effect on the environment. Ultrafiltration membrane is one of wastewater treatment technologies, but membranes have limitations such as the occurrence of the phenomenon of concentration polarization and fouling. The research objective of this study the effect of variations in transmembrane pressure against the rejection percentage BOD5, COD, TSS, and the effect of variations in transmembrane pressure, concentration of washing of the efficiency and effectiveness of washing the membrane. the concentration of the washing of the efficiency and effectiveness of washing the membrane. The process of ultrafiltration membranes and membrane chemical washing wastewater at the hotel do with variations in pressure of 0.5 bar , 1.5 bar , and 2.5 bar. Variation of chemical cleaning agent concentration of 1%, 1.5% and 2%, rinsing with distilled water for 30 minutes, for filtering wastewater hotel for 120 minutes, and washing using chemical cleaning agent (NaOH and Detergent) for 30 minutes. Results highest percentage of rejection was 83.1% for BOD5, COD parameter 69.6%, 66.7% TSS parameters in transmembrane pressure of 2.5 bar. The highest washing efficiency of the value of Flux Recovery (FR) gained 88.59%, and the value of resistance of Removal (RR) gained 95.00% in the washing detergent ingredients with a concentration of 2% in the transmembrane pressure of 2.5 bar. The highest leaching effectiveness obtained at 51.27% in the washing detergent ingredients with a concentration of 2% and a transmembrane pressure of 2.5 bar. Ultrafiltration membrane performance seen from the flux and rejection fit for use.Keywords: Ultrafiltration membrane, Fouling, Transmembrane Pressure, Efficiency of Washing, Effectiveness of Washing
