Chemicals that are known or suspected of being endocrine disrupting chemicals (EDCs) have received increased attention over the past decade for their potential presence in drinking water sources. This study focuses on the development of a hybrid system that combines the advantages of nanofiltration (NF) and homogeneous catalytic oxidation, which include compactness, operational facilitation, high treatment efficiency, and selective reaction capability. Iron(III)-tetrasulfophthalocyanine (Fe-TsPc) was employed as a homogeneous metal catalyst to degrade bisphenol-A (BPA), a representative EDC. The treatment efficiency of BPA as well as operational characteristics of the hybrid system was investigated to examine the applicability of this technique to decrease the concentration of EDCs in drinking water. Fe-TsPc homogeneous catalyst revealed a remarkable activity in degrading BPA under acidic condition. The high rejection of Fe-TsPc catalyst in the feed stream by the membrane for its large molecular weight (976 Da) and functional group (SO3− X4) allowed the continuous use of the catalyst for BPA oxidation reaction. The NF with Fe-TsPc/H2O2 hybrid system turned out to have higher BPA treatment efficiency comparing with the NF-only system since the hybrid system reduced BPA concentration in the feed stream by catalytic destruction of BPA as well as it mitigated concentration polarization on the surface of the membrane.

AbstractThe genus Klebsiella is seemingly ubiquitous in terms of its habitat associations. Klebsiella is a common opportunistic pathogen for humans and other animals, as well as being resident or transient flora (particularly in the gastrointestinal tract). Other habitats include sewage, drinking water, soils, surface waters, industrial effluents, and vegetation. Until recently, almost all these Klebsiella have been identified as one species, ie, K. pneumoniae. However, phenotypic and genotypic studies have shown that “K. pneumoniae” actually consists of at least four species, all with distinct characteristics and habitats. General habitat associations of Klebsiella species are as follows: K. pneumoniae—humans, animals, sewage, and polluted waters and soils; K. oxytoca—frequent association with most habitats; K. terrigena— unpolluted surface waters and soils, drinking water, and vegetation; K. planticola—sewage, polluted surface waters, soils, and vegetation; and K. ozaenae/K. rhinoscleromatis—infrequently detected (primarily with humans).
