Abstract

The clean water crisis becomes a world and Indonesia problem. One of the causes of the declining environment quality is the contamination of antibiotic. Potential used of antibiotics in hospitals causes residual antibiotics to be mixed in wastewater. Antibiotics are resistant and persistent in the aquatic environment even in small concentrations. Ciprofloxacin is one type of antibiotic that its use increases every year. Hospital wastewater treatment has not been designed for antibiotics, so it needs to develop alternative technologies to solve the problem. Membrane is one of the newest technologies in wastewater treatment. Membranes can be integrated between membrane types and between processing systems (Hybrid membrane). In this research, commercial membranes are used cellulose acetate (NF) and composite polyamid (RO). Scale experimental research laboratory capacity 300 L/day. The pressure operated is 80 psi with variation of Ciprofloxacin concentration 4, 5 and 10 ppm. Membrane performance variables are flux and rejection. The highest flux result in a solution of 4 ppm Ciprofloxacin NF 7.63 L/m2.jam and RO 6.10 L/m2.jam, 5 ppm at NF 7.46 L/m2.jam and RO 5.65 L/m2.jam and 10 ppm at NF 7.46 L/m2.jam and RO 5.76 L/m2.jam. The highest rejection of Hybrid membrane systems (NF-RO) were 98.25%, 97.4% and 98.4%, respectively. Hybrid membrane (NF-RO) has a good performance and can significantly reduce the level of Ciprofloxacin antibiotics.
