Tank Mixing Keeps Water Pure in High Temperatures for Texas City

Problem: League City, Texas, halfway between Houston and Galveston, fights brutally hot weather for much of the year. One effect is thermal stratification in water storage tanks, which can result in nitrification of drinking water and the loss of purification chemicals. The city needed a mixing solution. Solution: The city tried a large-bubble mixing system from Pulsed Hydraulics in a 1.5-million-gallon elevated storage tank. The system uses compressed air to create beach-ball-sized bubble masses at the tank bottom. Those bubbles race to the top, dragging cold water with them. This keeps chemicals in the solution and prevents thermal stratification. The system
