Effects of Activated Carbon on Reactions of Free and Combined Chlorine With Phenols (Chlorination, Gac)
… water treatment results in contact of free or combined chlorine with activated carbon, which is used to remove organic compounds from water. Free chlorine reacts with a group of phenols (phenol, guaiacol, catechol, 2,6-dimethoxyphenol, p-chlorophenol) in dilute aqueous solutions (10('-5)M), to …

Formation and removal of pesticides and pesticide transformation products during water treatment
… were examined for reactivity including free and combined chlorine, chlorine dioxide, permanganate, ozone, hydrogen peroxide, ultraviolet radiation, and high pH (alkaline hydrolysis). Due to the broad nature of the study, pesticide compounds were analyzed as multiple mixes broken into two groups …

A Comparative Study of Synergistic Effects in Sequential Inactivation of Cryptosporidium Parvum Oocysts and Bacillus Subtilis Spores With Chemical Disinfectants
… of interest for this study were ozone, chlorine dioxide, free chlorine and monochloramine, and the combinations of interest were ozone (or chlorine dioxide) followed by either free or combined chlorine. It is believed that understanding the process of oocyst inactivation by chemical …

Formation of (halo)acetamides and (halo)acetonitriles from the reaction of monochloramine and (halo)acetaldehydes in water
… unregulated nitrogen-containing DBPs formed by combined chlorine, such as haloacetonitriles and haloacetamides, might be more toxic than regulated DBPs. Monochloramine has been shown to react with aldehydes, common DBPs formed from ozone and free chlorine disinfection, to form carbinolamines …

Impact of Chloramination on the Development of Oligotrophic Biofilms
… reactor, chloramination at 8.5 ± 0.2 mg Cl2/L as combined chlorine was applied after two weeks of biofilm growth till the end of week 10. Confocal laser scanning microscopy combined with quantitative analysis using COMSTAT program revealed that disinfection resulted in a reduction of average …

Bacteriophage PRD1 as a potential surrogate for adenovirus in drinking water disinfection with free chlorine, low pressure ultraviolet light, and sunlight
… technologies such as ultraviolet (UV) light, combined chlorine, and solar disinfection. A potential surrogate for adenovirus is the bacteriophage PRD1 because of its similar size, morphology, and genome replication mechanism. The objective of this research was to compare the inactivation …
