Determining the correct amount of oxidant necessary to disinfect the untreated, or raw, <br /> water is dependent upon several measurable factors including: <br /> • types and amounts of microorganisms in the water; <br /> • water quality and chemistry-such measures as the turbidity and color, total organic <br /> carbon (TOC), pH, total dissolved solids (TDS), hardness, and biological or chemical <br /> oxygen demand (BOD or COD); <br /> • physical characteristics such as temperature; and <br /> • residence time in the line- that is, the time between when raw water is treated and <br /> when it is ready for use. <br /> WARNING! <br /> It is critical to use the correct amount of oxidant in the raw water in order to <br /> adequately remove any water-borne microorganisms that may cause illness or death. <br /> Before installing or operating the MIOX generator, the factors described in the preceding <br /> four points must be measured so that the correct Concentration x Time (CT) values can be <br /> calculated. Water systems that have seasonal variations in the water quality should obtain <br /> a series of measurements and use those measurements taken while water quality is the <br /> worst in calculating the proper mixture of oxidants. Measurements can usually be <br /> obtained from governmental health authorities, a licensed professional engineer, or a <br /> water analysis laboratories. Calculating CT values should be done by a competent health <br /> professional, professional engineer with water systems expertise, or other such competent <br /> professional. It is the operator's responsibility to ensure adequate dosing and <br /> maintenance of a chlorine residual in the water distribution system. Information about the <br /> mixed-oxidant dosing rate can be found in Section 11.7 Injection System Overview. <br /> Appendix4i-35 of 40 08/17/07 <br />
