Graphene nanosheets (GNS) such as graphenes and graphene oxides (GOs) have been
widely investigated as next-generation adsorbents in both water and wastewater treatment …

Drinking water treatment plants use granular activated carbon (GAC) to adsorb and remove
trace organics, but the GAC has a limited lifetime in terms of adsorptive capacity and needs …

Most heavy metals are well-known toxic and carcinogenic agents and when discharged into
the wastewater represent a serious threat to the human population and the fauna and flora …

The current project was developed to examine inactivation of biofilm bacteria and to
characterize the interaction of biocides with pipe surfaces. Unattached bacteria were quite …

Results of our experiments showed that the attachment of bacteria to surfaces provided the
greatest increase in disinfection resistance. Attachment of unencapsulated Klebsiella …

Wastewater treatment processes are inherently dynamic because of the large variations in
the influent wastewater flow rate, concentration and composition. Moreover, these variations …

While disinfection provides hygienically safe drinking water, the disinfectants react with
inorganic or organic precursors, leading to the formation of harmful disinfection byproducts …

Biofilter is one of the most important separation processes that can be employed to remove
organic pollutants from air, water, and wastewater. Even though, it has been used over a …

The authors review key parameters and engineering variables influencing biological
filtration and identify areas requiring further research. Biological filtration, an important …

Cells of mucoid and non-mucoid Pseudomonas aeruginosa in colonies were at least one-
thousandfold less sensitive to the antibiotics tobramycin or cefsulodin than were cells of the …
