The first continuous use of ,chlorine, in the United States for disinfection took place in 1908 at Boonton Reservoir (on the Rockaway River), which served as the supply for Jersey City, New Jersey. Chlorination was achieved by controlled additions of ,dilute, solutions of chloride of lime (calcium hypochlorite) at doses of 0.2 to 0.35 ppm.The treatment process was conceived by John L. Leal, and ...

Results show, besides the ability of producing active ,chlorine,, risks of inorganic disinfection by-products (DBPs) such as chlorate, perchlorate, nitrite, ammonium, chloramines, hydrogen peroxide and others. DBPs are responsible for analysis errors using DPD method for active ,chlorine, measurements. Geometry may influence by-product yield.
