Home - Tideflex Mixing Systems (TMS)  - TMS by Tank Style

TMS by Tank Style

    TMS are installed in all tank styles and materials including welded, bolted, and riveted steel, glass fused to steel, pre-stressed, post-tensioned, and cast in place concrete, and earthen reservoirs. TMS manifolds are available in the most common pipe materials including steel, HDPE, PVC, ductile iron, and stainless steel.

    Below is a brief description of the most common tank styles and TMS configurations for each one. There are some tanks with unique shapes and dimensions that do not fit the descriptions below and different TMS configurations are often utilized for those tanks.

    For every tank project, Tideflex engineers design the TMS based on tank style, volume, dimensions, flow rates, and expected turnover. The quantity, size, location, elevation and orientation of the Tideflex Inlet Nozzles and Waterflex Outlet Valves is based on CFD and scale modeling. The TMS design is customized for each tank because the variables always differ, even for identical size tanks. Manifold Hydraulics and Mixing Models are run by Red Valve engineers for every tank project.

Figure 1: Circular Tank Configuration

Circular Reservoirs

    Circular reservoirs are defined by the diameter of the tank being greater than the depth. Most of these tanks are below 40’ water depth and the TMS is a horizontal manifold with multiple Tideflex Inlet Nozzles and Waterflex Outlet Valves, (Figure 1).

    The TMS configuration (the quantity, size, location, elevation and orientation of Tideflex Inlet Nozzles and Waterflex Outlet Valves) is designed specifically for each tank based on diameter to depth ratio, fill & draw rates, and expected turnover.

Figure 2: Rectangular Tank Configuration

Rectangular Reservoirs

    Most rectangular tanks are also below 40’ water depth and the TMS is a horizontal manifold, (Figure 2). However, to eliminate mixing problems due to the corners of the tanks, the TMS configuration differs from that in circular reservoirs.

    The TMS configuration (the quantity, size, location, elevation and orientation of Tideflex Inlet Nozzles and Waterflex Outlet Valves) is designed specifically for each tank based on diameter to depth ratio, fill & draw rates, and expected turnover.

Figure 3: Standpipe Configuration

Standpipes

    Standpipes are defined by having a greater depth than diameter. Stanpipes can be over 140’ tall. The TMS is a vertical manifold with multiple Tideflex Inlet Nozzles spaced at different elevations and angles and Waterflex Outlet Valves at the bottom of the tank, (Figure 3).

    The TMS configuration (the quantity, size, location, elevation and orientation of Tideflex Inlet Nozzles and Waterflex Outlet Valves) is designed specifically for each tank based on diameter to depth ratio, fill & draw rates, and expected turnover.

Figure 4: Dry Riser Configuration

Elevated Tank - Dry Riser

    Dry riser elevated tanks have different styles but the most common are sphere/spheroids, hydropillars, and composite elevated tanks. The inlet/outlet pipe penetrates the bottom of the bowl. The TMS is a vertical manifold braced off the access tube and incorporates multiple Tideflex Inlet Nozzles at various elevations and angles and Waterflex Outlet Valves at the bottom of the bowl, (Figure 4).

    The TMS configuration (the quantity, size, location, elevation and orientation of Tideflex Inlet Nozzles and Waterflex Outlet Valves) is designed specifically for each tank based on diameter to depth ratio, fill & draw rates, and expected turnover.

Figure 5: Wet Riser Configuration

Elevated Tank - Wet Riser

    Wet riser elevated tanks (also known as multi-column tanks) have a large riser pipe, typically between 36-120”diameter, located at the center of the tank and runs from ground level into the bottom of the bowl. The inlet/outlet pipe penetrates the wet riser at ground level. The wet riser is actually the inlet/outlet into the bowl. The TMS is a vertical manifold with multiple Tideflex Inlet Nozzles up in the bowl and Waterflex Outlet Valves at the bottom of the wet riser near ground level, (Figure 5).

    The TMS configuration (the quantity, size, location, elevation and orientation of Tideflex Inlet Nozzles and Waterflex Outlet Valves) is designed specifically for each tank based on diameter to depth ratio, fill & draw rates, and expected turnover.
