ABSTRACT:
A simplified, energy efficient, low cost liquid flow controlling weir apparatus is provided for "in tank" flow equalization and surge control. The apparatus is especially adapted for use in waste water treatment plants at tank outlets, and includes first and second, opposed, spaced apart upright weirs; the inboard first weir adjacent tank water is of lesser height than that of the outboard weir, and the latter is provided with one or more apertures therethrough at a level below the upper margin of the first weir. When water within the tank rises past and overflows the inboard weir plate, liquid flow is controlled by the outboard weir plate openings, water is rapidly backed up in the tank as storage, and tank discharge is maintained at a relatively uniform rate until the tank storage capacity is reached. The outboard weir plate prevents tank overflow, and is advantageously set at a height for overflow at 125-135 percent of design flow through the system.
