Westfall - Model 5000 -Open Channel Static Mixer
New Low Headloss Static Mixer Reduces Flooding and Fouling. The Westfall Open Channel Static Mixer 5000 introduces a new global standard in open channel mixers. The recently patented design offers a simple infrastructure solution that is applicable worldwide.
One to three hydro-dynamic vanes are anchored linearly along the bottom of the open channel. These patented vanes are designed to resolve the major problems engineer’s face (such as fouling, pollution from runoff, reduced flow caused by drought and flooding from excessive headloss or storms) when moving water along open channels, ditches, conduits, canals, tunnels and aqua ducts.
To counter these problems, the angled vanes are designed to resist fouling, improve mixing and reduce headloss,. CFD tests conducted by Alden Laboratories predict that the single vane model has a CoV of 0.134 and headloss of 0.89. The two-stage version has a CoV of 0.062, with headloss of 1.78. The three-stage version has a CoV of 0.016 and headloss of 1.82.
Open Channel Static Mixers, as opposed to Dynamic Mixers, contain no moving parts. They require little external energy to operate.
There is a continued need worldwide for open channel static mixers that achieve the same or better mixing outcomes as propeller and rotating blade mixers, that are less expensive to manufacture and operate, that are lightweight, easy to install and resist fouling. They can be used in remote locations where power is scarce.
