Halogenated organics generated during online chemical cleaning of MBR : an emerging threat to water supply and public health

The global wastewater treatment capacity of MBR has been constantly growing due to the strong needs in water reuse/cycle and restrictive availability of land. Recent research revealed generation of a variety of halogenated organics during online chemical cleaning of MBR with sodium hypochlorite (NaC...

It should be realized that the potent environmental and public health risks associated with produced halogenated organics in MBR permeate have not yet been aware and assessed in consideration of the entire water life cycles. Therefore, this article attempts to express serious concern on, while raising scientific and public awareness on this emerging issue.
