The ability of chlorine to kill germs depends on both the concentration of chlorine in the water and the amount of time that the chlorine has to react with microorganisms (contact time). The chlorine dioxide achieves an equilibrium at a low concentration. The decrease in absorbance of the band at 360 nm in different reaction systems was obtained, and based on the standard curve fitting equation (Figure 2b), the consumption of chlorine dioxide was calculated. 1. The chlorine that does not combine with other components in the water is free (residual) chlorine, and the breakpoint is the point at which free chlorine is available for continuous disinfection. Concentration: The concentration is defined as the total quantity of solute present in a fixed amount of solution or solvent. The use of chlorine dioxide reduces the health risk of microbial pollutions in water and at the same time decreases the risk of chemical pollutions and byproducts. How do they affect disinfection? chlorine solution (5,000 ppm) from 8.25% … To monitor … Decomposition … Any remaining chlorine concentration after the chlorine demand is met is termed total chlorine. 8 a) At pHs < 8, significant levels of HOCl are present-b) If NH 3 is present, HOCl will react to form one of 3 chloramines depending on pH, temperature, & reaction time. The choice of the chlorine type to be used often depends on cost, on the available storage options and on the pH conditions required.
