Method for reservoir mixing in a municipal water supply system

摘要

One or more turbulent jet flows of fluid are discharged from inlet nozzles communicating with an inlet pipe to mix fluid in a reservoir, such as a water storage tank. The turbulent jet flows are directed to reach the surface of the fluid already existing in the reservoir. A horizontally disposed outlet section includes low loss contraction nozzles distributed throughout a lower portion of the reservoir to induce draining from all areas of the lower portion.

1. A method of mixing water in a municipal water supply reservoir, the reservoir holding a variable volume of water that varies between a low water level and a high water level as defined by a surface of the water, the method comprising the steps of:
positioning an inlet pipe and an inlet nozzle in the reservoir, the inlet nozzle communicating with the inlet pipe and being located below the low water level to be submerged in the water, wherein the inlet nozzle includes a reducer, an elongated nozzle pipe mounted to an exit end of the reducer, and a duckbill check valve mounted to an exit end of the nozzle pipe; and discharging a turbulent jet flow of water from the inlet nozzle into the reservoir, wherein the turbulent jet flow of fluid is directed upward toward the surface of the water and reaches the surface of the water in the reservoir.
