Thermally Homogenous But Chemically Stratified: Active Mixing Achieves Uniform Residual Levels In 5 MG Concrete Tank

Pinellas County, Florida is typical of many major metropolitan water systems, with over 700,000 customers, 2,000 miles of piping and several large water storage facilities. Like many major metropolitan water systems, Pinellas County Department of Environment and Infrastructure (DEI) has seen a decline in water usage over the last decade, both due to active water conservation programs and downturns in the regional economy. This decrease in water usage has increased water age, and coupled with warm southern temperatures, has increased incidences of nitrification in parts of their chloraminated system.
