In most cases, the calculations are straightforward and only require a ratio of needed chemical additions per amp hour units. The following is a step-by-step example of how to derive a series of options for an actual situation.
  • Page 8 *** Break Down the Ratio to a Usable Level *** When rounding seconds, always go down to the next lowest whole second (e.g.; 50.9 sec. = 50 sec; 50.1 sec. = 50 sec.) When rounding amp/hours, always round up to the next whole amp/hour (e.g.;...
