Komax Systems Designs World’s Largest In-Line Static Mixer

The world’s largest in-line static mixer for chlorine mixing was designed, fabricated and shipped by Komax systems, Inc. Wilmington California.  Designed especially for the Metropolitan Denver (Colorado) Waste Water Treatment Plant, Komax’s success with this application only reaffirms its position as the world leader in static mixing technology.

 Designed around exacting size parameters for easy of installation and specific mixing requirements, this rectangular mixer measured 30 feet in length by 10 feet in both height and width.  Fabricated from type 316L stainless steel plates and shapes with a minimum thickness of ¼ “, the mixer weighed in at an incredible 4 tons.  

The mixers installation site is a conduit from the South Plant which handles secondary effluent at a normal flow rate of 80 to 100 mgd.  Complete with a diffuser capable of injecting and rapidly mixing a chlorine solution into the flow stream of the final basin effluent, the mixer produces a completely mixed solution at all design flows without using any moving parts.

 With installation complete, preliminary tests were initiated to determine the diffusion/mixing characteristics of the chlorination system and all results for the Komax mixer turned up positive.  One conclusion determined that “…at a design flow rate of 100+/- 10 mgd, the Komax system is economical for efficiently and rapidly mixing chlorine (or other chemicals) into the secondary effluent”.

 After six months of operation, testing was initiated once more indicating positive results once again.  The conclusive summary of this testing was that “The Komax diffuser/mixer substantially improved the disinfection process of the South Complex by providing acceptable concentrations of fecal coliform bacteria at chlorine residual significantly less than those of the pre-Komax existing system”.  

 The above conclusions as stated in test data proved that the Komax mixer performed extremely well providing reduced chlorine usage and high monetary savings.  Due to superior diffusion/mixing, the chlorine injected into the effluent stream was cut back by approximately 50%.  Residual chlorine was also reduced along with fecal coliform thus keeping in compliance with NPDES requirements.  Due to these savings, the payback period decreased significantly meaning total cost effectiveness and one of the most technically advanced treatment plants in the nation.
