Mixer eliminates thermal stratification
Problem
Operators at the Spanaway (Wash.) Water Co. discovered thermal stratification inside a 127-foot steel standpipe after noticing heavy condensation each morning at the bottom 30 feet. Probes installed at 20-foot intervals in the tank measured temperature differences as great as 19 degrees F. Water samples indicated 0.7 mg/L chlorine residual at the bottom of the tank and almost zero residual at the top. Poor-quality water entering the distribution system often triggered taste and odor complaints.
Solution
Operators installed a single Water Mixer from PAX Water Technologies in less than a day
