Abstract
A means for mixing drinking water stored in large storage tanks, preventing stratification of the water, detects incipient stratification of water along thermoclines, and, responsive to thermocline detection, generates large mixing bubbles toward the bottom of the tank, causing mixing of layers of water in the tank through turbulence created as the bubbles rise through the tank.
