The present invention provides a new and improved method for treating drinking water in a drinking water treatment plant that provides for substantial or complete removal of chlorine dioxide and an associated by- product from water when chlorine dioxide is used as an initial disinfectant and/or ...
chloride and copper (II) ions, the concentration of diisodecyl dimethyl ammonium chloride in said water being less than about 60 parts per million parts of water by weight and treating said water at least intermittently with an oxidant selected from the group consisting of available chlorine and ...
Sodium hypochlorite met bacteria and virus standards for the graywater at a free-chlorine concentration×time (CT) well below the 450(mg/L)-minrequired by California drinking water standards. An ozone CT of 0.4(mg/L)-minmet bacteriological standards for reuse in two of the four samples. ...
(iodine and chlorine) are the least effective because of the variable results based on such things as the concentration of the halogen, contact time with the germs, the clarity of the water, the temperature of the water, and the questionable efficacy of iodine and chlorine againstCryptosporidium...
Chemical disinfectants commonly used by the water industry such as free chlorine, chloramines and ozone can react with various constituents in natural water to form disinfection byproducts (DBPs), many of which are carcinogens [3]. The rapid growth in nanotechnology has generated interest in new ...
The problem is apparently caused by chlorine reacting with the cholesterol and causing it to coagulate on the walls of the arteries, forming plaque. The sources of chlorine are many, but the major ones are the drinking water supply and the salt in food. We have been told to lower our inta...
