Chlorine is present in most disinfected drinking-water at concentrations of 0.2–1 mg/litre (3). Food Cake flour bleached with chlorine contains chloride at levels in the range 1.3–1.9 g/kg.
18 Σεπ 2024 · Chlorine sensors ensure that the right amount of chlorine is present in the water – enough to kill harmful microorganisms, but not so much as to pose health risks or affect taste and odor. They are essential tools in both large-scale water treatment facilities and smaller, point-of-use applications.
Exposure to chlorine through drinking water is expected to be very low. Free chlorine in drinking water is defined as the sum of dissolved chlorine gas, hypochlorous acid, and hypochlorite anion.
Chlorine. Chlorine is produced in large amounts and widely used both industrially and do-mestically as an important disinfectant and bleach. In particular, it is widely used in the disinfection of swimming pools and is the most commonly used disinfectant and oxidant in drinking-water treatment.
Available information on the obvious major candidates for drinking water disinfection—chlorine, ozone, chlorine dioxide, iodine, and bromine—is then evaluated for each method individually in the following sections.
1 Ιαν 2015 · The application of chlorine to water treatment poses risks by producing by-products such as organochlorinated compounds. Disinfection by-products (DBPs) such as trihalomethanes, haloacetic acids, haloacetonitriles and haloketones are formed when chlorine reacts with natural organic matter such as humic acids and phenols.
Chlorinated drinking water is unlikely to be harmful when discharged into aquatic environments. An extensive risk assessment conducted under European Union guidelines examined potential harm from various processes to make drinking water using sodium hypochlorite.
