Changes in optical properties and molecular composition of dissolved organic matter and formation of disinfection by-products during conventional water treatment processes

Abstract

Dissolved organic matter (DOM) presents ubiquitously in natural water environments. It is inevitable that DOM enters water treatment plants (WTPs) consisting in raw water. When in a WTP, DOM introduces...

Study on the efficiency of the preoxidation–coagulation process in removing disinfection by-product precursors from micropolluted water

“…In the disinfection of drinking water with chlorine, DBPs are produced by reacting with natural organic matter (NOM) and dissolved organic matter (DOM). [2][3][4] Most of the DBPs that have been identified and detected have genetic, cellular, and neurological toxicity, 5 affect human pregnancy and induce cancer cell formation. [6][7][8] The diversity of DBPs formed is high and a large portion remains unknown.…”
