Per Regal Systems, use a simple formula to see your maximum flow rate of water or wastewater in a day with your target chlorine dosage needed. The formula is lbs./day chlorine - (0.012) X (flow rate in US gpm) X (dosage in ppm). You need to allow for an oversizing safety factor of at least twice the required dosage rate of chlorine.

So for example if you need 2 ppm dosage of chlorine for a water treatment station pumping up to 1000 gpm, that breaks down to: 24 lbs./day = .012 X 1000 gpm X 2 ppm. Doubling that for safety equals 50 lbs./day needed from a gas chlorinator.

The standard gas chlorinators are manually switched out when service is needed while the switchover system design features a back-up chlorinator so there is continuous chlorination even if one of the chlorinators need maintenance.

The flow diagrams below show the standard unit and switchover unit.

Because a vacuum is needed for the gas chlorine to flow, the risk from leaking is minimized since that would result in the vacuum pressure stopping.
