Appendix A - Water Quality Guidelines
Knowing what to look for when sizing a system will help remove hidden surprises after
installation. Most of the items on the following list will be below the limits but should be
checked nonetheless. Concentrations or measurements in brine feed water and/or treated
water that are less than the stated limits are not anticipated to have the stated effect.
These factors can affect the oxidant demand of each individual water system, the oxidant
production of the MIOX system, or the life of the cell itself. It is important to use “worst
case” measures since water quality can vary from season to season.

**Caution: water softeners will remove these components up to a limit. See references to
maximum ferrous iron and manganese in water softener documentation. Total hardness
affects cell life only in that higher hardness requires acid washing to remove carbonate
deposits from the cell. Use of water softened to < 1 grain hardness should not require acid
washing of the cell.
*** Oxidant demand is affected by any level of H2S, ammonia or organic nitrogen, or TOC.
