Abstract
Biological degradation of pharmaceutical wastewater followed by reverse osmosis (RO) membrane technology was investigated. The Membrane separation of Dextromethorphan was performed in a continuous mode operation. Synthetic wastewater was prepared by addition of desired amounts of Dextromethorphan to deionized water. Experiments were performed at room temperature and the pH correction. The effective operational parameters included pH correction; contact times, Dextromethorphan concentration and RO were studied consecutively.The effect of mixing various techniques by chemical, biological treatment (aerobic and anaerobic) and physical processes had good opportunity to get more removal%. The final step was reverse osmosis membrane to remove all suspended and dissolved solids. The efficiency of full treatment plant was 20.9%, 99.9%, 99.5% and 93.9% for pH, COD, TSS and TDS respectively. The produced water could be reused and recycled.
