Chlorine is also a strong oxidizing agent that will break up organic matter in water, but in so doing, because it is a highly reactive chemical, it can form a wide range of chlorinated compounds with the organic matter present. Among these are the trihalomethanes and haloacetic acids for ...
Disinfections of Water by N-Hal amine Biocide PolymersAlthough this newfound awareness of infectious disease is being fomented by media attention, its root causes are real enough. These diseases derive from the declining effectiveness of antibiotics; the appearance and rapid spread of entire...
However, the catalyst reactor surface had the greatest effect on inactivation of the bacteria when the reactor surface area was increased. Water temperature less than 45掳C did not affect the decrease in the rate of inactivation of the bacteria for either solar or photocatalytic disinfection....
Communities living in developing countries as well as populations affected by natural or man-made disasters can be left at great risk from water related diseases, especially those spread through the faecal-oral route. Conventional water treatments such a
