In water treatment history, the problem of increased concentration of disinfection byproducts (DBPs) started to emerge in the early 1900s. This is when chlorine (and ozone) started to be applied as primary disinfection agents for drinking water. A reaction of the disinfection agent with organic compounds present in water often leads to the formation of various types of DBPs. Throughout the years, with a growth in awareness around the negative impacts of DBPs on human health, previously underutilized DBP removal technologies gained importance while new ones have also been developed.
