Removal of THMs by Aeration in a Conventional Lime/Soda Softening Plant With High DOC Water

Surface waters, such as lakes and rivers, often have high amounts of natural organic matter formed from decaying plants and animals. Drinking water treatment plants that use these water sources often face with high levels of carcinogenic chlorine disinfection by-products (DBPs) which are result of reaction between natural organic matters and chlorine that is added to water for disinfection. Canadian water quality guidelines set maximum acceptable levels for these harmful DBPs and hence water treatment plants are obliged to come up with appropriate solutions to meet the guidelines. There are different strategies to reduce DBPs including: enhance removal of organic matters, application disinfectants alternative to chlorine, or removal of DBPs after they have been formed. This project aims to study aeration of potable water as a strategy for removal of DBPs specially trihalomethanes (THMs). TO BE CONT’D
