Channel (STMC) and Duct (STMD) Mixers




Statiflo’s channel and duct mixers have revolutionised the design and operation of water and wastewater treatment plants.

Complete mixing in the channel is possible, achieving a low CoV, over a wide range of flowrates. With head losses of just a few millimetres feasible, gravity flow is an option, eliminating the expense of pumping, saving not just capital costs, but ongoing maintenance and energy costs too.

Statiflo Channel Mixers can be installed in new treatment works or easily retrofitted into existing installations because of the extremely low headloss.

The modular design concept, based on the STMC mixing element, allows wide variations in aspect ratio (height/width) suitable for square or nearly square channel sections, narrow deep channels and wide shallow channels. We have even designed Channel Mixers for circular collectors around clarifiers for pH adjustment prior to chlorination.

Independent trials have established that the STMC concept is the most efficient of all known commercially available static mixers, making it ideal for chemical dosing as a fundamental component of process control. It is indispensable before flow splits to ensure equal chemical distribution and balanced performance of parallel trains of treatment operations.

Typical applications:

– Raw water blending
– pH control
– Rapid coagulation/dosing
– Polyelectrolyte dosing
– Chlorination/dechlorination
– Residence time control
