AquaBlend provides mixing in water storage tanks by firing programmed short bursts of impurity-free compressed air through patented engineered nozzles. The controller air injection valve intermittently fires to blend from the tank bottom to the water surface. The large bubbles create a distinctive mixing pattern, or “tank roll.” The blending parameters of the controller may be adjusted by the operator for optimal mixing and power utilization, or the automated instrumentation feedback control system may be used.
