Chlorine test kit sensitive enough to detect chlorine level below 2 ppm and up to 10 ppm (may need two kits). Free chlorine may be measured when it is known that chlorine is the method of disinfection (as opposed to monochloramine, bromine, or another disinfectant). Otherwise, measure total chlorine. Thermometer. Sample data sheet and pens.
chlorine residual concentration or the contact time. For example, if water at the entry point to the distribution system has a free chlorine residual of 0.5 mg/L and the chlorine is in contact with the water for 10 minutes between chlorine injection and entry point to the distribution system, CT is 5 (0.5 mg/L x 10 min = 5 mg-min/L).
“free chlorine.” (Free, uncombined chlorine, Cl 2, is rarely found in wastewater since the conditions of formation are relatively extreme [Lind, 1995]). Once formed, the free chlorine reacts with natural organic matter in water and wastewater to form chlorinated organic compounds. The free chlorine also combines with ammonia to form mono-, di-,
fresh clean water. If you have concerns over the age of the water and chlorine residuals found in a water hauling truck, you can request that the water supplier test the chlorine residual in the water upon delivery and prior to refilling. Chlorine test kits are also available from swimming pool suppliers and chemical suppliers. Adding some chlorine
Adequate post chlorine dosing detention time is available within the water supply system, typically at least 30 minutes is required to complete the disinfection process and ensure a minimum free residual chlorine level of 0.5 mg/L Includes a residual chlorine test kit to be used for regular monitoring (e.g. daily or weekly) of residual chlorine ...

F. Solubility in Water Chlorine is not very soluble in water and more can be dissolved in water at lower temperatures. Since chlorine is such a strong oxidizing chemical, it reacts with various constituents in wastewater, forming chlorine compounds. Common compounds would be the formation of chloramines.

impacts safety standards. For clean water, 3 to 5 ppm free chlorine provides more than adequate microbial control for free-floating bacteria in a very short contact time. This water quality likely results in measurements of 650–700 mV ORP if the water pH is 6.5 to 7. Lowering the pH to 6.0 raises the ORP, as more hypochlorous acid (HOCl)
