Chlorine has been used to disinfect water for consumption in the US since the early 1900's, leading to the virtual elimination of waterborne diseases and improved public health. It is extremely effective at killing pathogens and diseases, is inexpensive, easy to control and monitor, as well as ...
Average biofilm formation rates are 325 ATP pg/cm2 per day for chlorine-free water, 159 ATP pg/cm2 per day for low-chlorine water and 118 ATP pg/cm2 per day for high-chlorine water. Scanning electron microscope (SEM) observation showed that bacterial species separated from the biofilm ...
In this substudy, we leveraged stool samples collected from 130 children 1 year after chlorine doser installation to examine differences between treatment and control children’s gut microbiota. Water chlorination was associated with increased abundance of several bacterial genera previously linked to ...
The results suggested that the combination of NF-UV and NF-H2O2 could remove 71% and 74% of all the hormones giving high-grade water. Application of these treatment combinations can further lower the chlorine required for final disinfection and distribution. Sudhakaran et al. [11] performed an...
