Finding the right pump technology is crucial when dealing with this chemical and its harsh effects on humans and the environment in high. 003 = Cl2 Feed Rate (GPH) Once the feed rate of the metering pump is determined, then a metering pump with the proper capacity can be selected. In the calculations of dosages or concentrations, 10 percent should be used as the starting point. 5% Sodium Hypochlorite, 39-47% Ferric Chlorite, Sodium Bisulfate and 98% Sulfuric Acid ranging in sizes from 0. Unfortunately, with the "off gassing" effect of the hypo this is a difficult duty, especially when the pump must also self-prime dry with a 7 foot suction lift. New air conditioned electrical and transfer pump building. The maximum flow of water into the house may be around 10 GPM. Once set, the chemical dosing rate will automatically adjust proportional to the flow rate through the unit - for example, when chlorinating, as the flow rate drops as the pipeline is almost full, the dose rate for the sodium hypochlorite will also drop. 25% hypochlorite solution = 792 fluid ounces. 006 = Cl2 Feed Rate (GPH) Using a 2% Solution: Flow Rate (GPM) X Demand (PPM) X 0. 5% by weight sodium hypochlorite is also used for water disinfection.
