Abstract:
The efficiency of sequential advanced membrane technology wastewater treatment plant towards removal of amoxicillin and cefuroxime axetil from wastewater was investigated. The sequential system included activated sludge, ultrafiltration (hollow fiber membranes with 100 kDa cutoff, and spiral wound membranes with 20 kDa cutoff), activated carbon column and reverse osmosis (RO). The overall performance of the integrated plant showed complete removal of amoxicillin and cefuroxime axetilfrom spiked wastewater samples. The adsorption isotherms for these compounds have been studied using both activated carbon adsorbent and newly developed adsorbent named micelle-clay complex (octadecyltrimethylammonium(ODTMA)–clay (montmorillonite)). The results revealed that both isotherms adsorption fit the Langmuir equation with Qmaxof 100 mg/g and 90.91 mg/g,and with K values0.229 L/mg and 0.158 L/mgfor amoxicillin using activated carbon and micelle-clay complex, respectively, and with Qmaxof 26.31 mg/g and 31.25 mg/g and with K values0.271 L/mg and 0.122 L/mg for cefuroxime axetil using activated charcoal and micelle-clay complex, respectively. Removal of amoxicillin and Cefuroxime axetilfrom polluted waterin high concentrations (100 ppm) by column filter including a mixture of micelle-clay or activated charcoalcomposite with sand indicated an efficient removal of both pharmaceuticals.
