Progress in Chemical Handling and Feeding at Chicago
This article discusses improvements in chemical handling and feeding at Chicago's South District Filtration Plant. Experiments have established that activated carbon can be stored in water for a year without any change in its adsorptive capacity. Discontinuing dilution of the liquid in the storage tanks has eliminated the problems of foaming and slime growths in liquid alum systems. Improvements in the handling and feeding of ferrous sulfate are discussed, along with the use of hydrofluosilicic acid for fluoridation, and as a back‐up in the event hydrofluosilicic acid is not available, the use of sodium silicofluoride for fluoridation, improvements in the handling and feeding of pebbled quicklime, the use of ammonium sulfate in chlorine‐ammonia treatment of filtered water, and the testing of five different materials for the lining of concrete or steel tanks that hold liquid chemicals.
