Upgrading Hospital wastewater treatment plants by Low cost Innovative technologies (Paperback) (ISBN-13: 9798698327172)

This book investigates the removal of pharmaceutics present in hospital wastewaters by conventional activated sludge and MBR systems of treatment and under various operating conditions to elucidate the removal mechanism and increasing the efficiency of removal. In this study, laboratory scales was composed to four types of reactors used: Bach reactors, conventional activated sludge, submerged membrane bioreactor and extern membrane bioreactor and all these reactors were feed in reel hospital wastewaters. Different Technical studies and many experiments were affected to develop the MBR systems: the beginning was with biofilm supports media and the attached growth of biofilms in the reactor and the finish by using the powder activated carbon. En general, the reported results show high performance for the MBR with compared to CAS system in treating the basic organic pollutants. Presence the biofilm supports media was very important for high removal of pharmaceuticals compounds from the hospital wastewaters. The presence of the pharmaceutical compounds stimulated the mechanisms of survival higher production of EPS. Fouling potential seems to be linked more closely to polysaccharides than other EPS. In this study, for the first time, was employed the confocal microscopy for qualities and quantities analyses for the EPS in the biologic reactors. Microscopic observations were confirmed the chemical analyses of EPS compounds.In final experiment 21 pharmaceuticals were eliminated from the hospital effluents during the treatment in extern membrane (UF) with modified granular activated carbon. In addition to many biomolucles analyses which study the principals impact of hospital effluents on the microorganism's especially the bacteria in using different, recent techniques. This study demonstrates by reel conditions the role the developed MBR systems in treating the hospital effluents and its impact direct on the environment.
