BACKGROUND Human exposure to antibiotic resistant bacteria (ARB) is a public health concern which could occur in a number of ways. Wastewaters seem to play an important role in the dissemination of bacteria and antibiotic resistant genes (ARGs) in our environment. The aim of this study was to evaluate the occurrence of three groups of ARB and their resistance genes in hospital and municipal was...

Nervous system active pharmaceutical ingredients (APIs), including anti-depressants and opioids, are important clinically administered pharmaceuticals within healthcare facilities. This study provides source characterization data describing the composition and magnitude of nervous system APIs present in healthcare facility wastewaters. Concentrations and mass loadings of ten nervous system APIs...

The principal sources and pathways of pharmaceutical and personal product (PPCP) compounds within an urban drainage system are identified with combined sewer discharges from households and infiltration from landfill/land sludge applications constituting major routeways. Illicit connections, sewer exfiltration and reclaimed domestic wastewaters comprise potentially significant other contaminant ...

The increase of the industrial activity and the consequent economic and social development have produced, at least until some years ago, a growth of big cities which leads and complicates the supply of one of the most important elements to the life, “water”. Nowadays, faced with the growing water demand and the hydric resources shortage, the reuse of treated water is considered as a possible so...

This revision work focuses on the recent advances in separation of microcontaminants from urban wastewaters, using ultrafiltration and Nanofiltration membranes. Conventional systems show advantages such as low pressure fouling, competitive energetic- maintenance costs compared to reverse osmosis, higher rejection rates organic membrane distillation. However, these strongly depend temperature, f...
