The potential throughput capability is dependent on the water analysis and the level of both sulfate and TOC. However, the actual multiple cycle operating capacity is also limited by the amount of organics that can be regenerated from the resin. At regenerant levels above 10 lbs./cu. ft. the contact time is more important than the dose level for removing organics from the resin.

Above capacities based on salt regeneration, 60 minutes contact time, plus 30 minutes post-regenerant soak, all at ambient temperatures. The three examples above are based on the following water analysis:

Above 10 lbs./cu.ft. dose, the amount of organics removed during regeneration will be proportional to the total contact time of the regenerant in the resin bed, including the displacement rinse (slow rinse) plus the post-regenerant soak time for up to 100 minutes. Longer contact times provide only marginal benefit. It is recommended that a minimum regenerant contact time of 60 minutes be used. If more capacity is needed, then a post-regenerant soak between the regenerant introduction and the displacement should be added.

Once the potential throughput capacity is determined, the regenerant contact time and dose required to remove the organics is determined. Comprehensive performance information is available for specific water analysis (bicarbonate, chlorides, sulfate, and TOC) from the manufacturer.

In some cases the regeneration process will limit the throughout capacity.
