3050 Static Mixer — Ultra Low Headloss
Westfall Model 3050 Static MixerPatent Pending

The Westfall Model 3050 Mixer was developed for situations with low available head. The mixer consists of a length of pipe fitted with four vanes. The tapered and curved vanes create vortices and multiple zones of turbulence that intersect to turn flow inside out. This produces good mixing while reducing headloss.

Features:
- Mixes well in situations with low head
- Creates minimal headloss—two to four times less than other mixers
- Saves space with short pipe length—just one diameter
- Is available in pipe diameters from 1/2” to 120”
- Low cost, easy installation
- Long service life and low maintenance requirements
Applications:
- Municipal and Industrial Water Treatment
- Potable Water
- Waste Water
- Chlorination/De-Chlorination
- Chemical Blending
- Dissolving Gases
- Contact Chambers
- Flocculant Blending
- Anaerobic Digestion
- Dewatering
- pH Control
- Contacting
- Product Blending
Alden Research Laboratory, Inc. performed numerical simulations using the CFD software package FLUENT V6.3.26, a state-of-the-art, and finite volume-based fluid flow simulation package, to calculate the three-dimensional, incompressible, turbulent flow through the pipe and around the mixer.
They simulated a 32-MGD water flow in a 36-in I.D. steel pipe, after two out-of-plane 90° bends. The flow conditioner is installed 4D downstream of the second bend.
