Disinfection of Water ConditionersThe materials of construction of the modern waterconditioner will not support bacterial growth, nor willthese materials contaminate a water supply. However,the normal conditions existing during shipping, storageand installation indicate the advisability of disinfecting aconditioner after installation, before the conditioner isused to treat potable water. In addition, during normaluse, a conditioner may become fouled with organicmatter or in some cases with bacteria from the watersupply.Thus every conditioner should be disinfected afterinstallation, some will require periodic disinfectionduring their normal life, and in a few cases disinfectionwith every regeneration would be recommended.Depending upon the conditions of use, the style ofconditioner, the type of ion exchanger, and thedisinfectant available, a choice can be made among thefollowing methods.Sodium or Calcium HypochloriteApplicationThese materials are satisfactory for use withpolystyrene resins, synthetic gel zeolite, greensand andbentonites.5.25% Sodium HypochloriteThese solutions are available under trade names suchas Clorox Bleach 1 . If stronger solutions are used, suchas those sold for commercial laundries, adjust thedosage accordingly.1. DosageA. Polystyrene resin: 1.2 fluid ounces per cubicfoot.B. Non-resinous exchangers: 0.8 fluid ounce percubic foot.2. Brine tank conditionersA. Backwash the conditioner and add the requiredamount of hypochlorite solution to the brine wellof the brine tank. (The brine tank should havewater in it to permit the solution to be carried intothe conditioner.)B. Proceed with the normal regeneration.Calcium HypochloriteCalcium hypochlorite, 70% available chlorine, isavailable in several forms including tablets andgranules. These solid materials may be used directlywithout dissolving before use.1. DosageA. Two grains (approximately 0.1 ounce) per cubicfoot.2. Brine tank conditionersA.
