Info

A phased constructionapproach was used for theinstallation of the currentsodium hypochlorite system.Due to project budgetlimitations, lengths from thesource and desired splits, thecarrier water method was usedto convey hypochlorite to feedpoints within the plant.
The current hypochlorite system includes two bulkstorage tanks, one day tank, three feed pumps, new feedpiping, distribution panels, and spill containment.Sodium hypochlorite is stored in bulk cylindricalshaped 6,100-gallon polyethylene tanks providing atotal bulk storage of 12,200 gallons.Sodium hypochlorite flows by gravity from the bulkstorage tanks to a 550-gallon polyethylene day tank.
