The Deskins RapidFloc Mixer: Timeless and efficient technology. The Occam's Razor for sludge preconditioning!

Many of Deskins' RapidFloc installations are still in operation to this day from over 25 years ago. One of these sites is in Winchester, IN with the same RapidFloc being utilized dating back to 1993.  Being a steward of sustainable solutions, Dave Deskins, CEO of Deskins, wanted to create a product that contained no planned obsolescence.   At Deskins, we create and utilize energy from natural laws of fluid dynamics. In other words, we utilize the natural laws the creator has instilled in nature. This is why our technology has worked for over 25 years on centrifuges, screw presses, belt presses and our very own Deskins Quick-Dry Filter Bed System. 

The RapidFloc Mixer utilizes the laws of physics, fluid dynamics and fluid mechanics to its full advantage. It is superior over traditional static mixers and lever action weighted valves because of its limited headloss and its ability to recirculate the polymer for more sludge to polymer contact. Also, the flow in a traditional static mixer is more laminar than turbulent. The more laminar the flow the lower the Reynold’s number. In the three standalone pilots with The RapidFloc, Deskins has saved an average of 30% in polymer and increased hydraulic throughput by as much as 25% for these facilities. The Continuity Equation, Bernoulli’s Principle and Venturi Effect all work in concert to maximize its efficiencies. These principles and effects have working parts all interrelated to each other. Fluid finds the path of least resistance. The medial bar helps in that capacity and recirculates the polymer/sludge once again. Utilizing the Continuity Equation sludge/polymer moves faster through this bar because it is smaller than rest of the piping. The baffles positioned alternately throughout the RapidFloc create pressure drops resulting in higher hydraulic throughput and polymer mixing. The faster the flow rate of the sludge/polymer the higher the Reynold’s number as it relates to the viscosity of the polymer/sludge. Let's quantify this,  the equation is-inertia force/ divided by viscous force. The higher the Reynold's number, the more turbulent the flow. This enables higher mixing values.
