RK2 Foam Fractionators

The fractionation filtration process is simple and highly effective. Air, (in some cases ozone as well), is injected into the bottom of the reaction chamber via an ozone resistant venturi injector. The water to be filtered is introduced at the top of the chamber and exits at the bottom. This creates a mass mixing effect, with the water traveling cross current to the air, which is essential for the effective formation of foam. The foam rises through the column and becomes more concentrated as it passes into the upper rise tube. The tube allows for the water to drain back into the tank via gravity, while the concentrated foam is ejected over the top of the riser tube and collected into a waste drain. The upper chamber is automatically washed down with rinse systems that keep the surfaces clean and prevent the foam from drying and inhibiting the ejection process. The protein fractionation process increases water clarity and oxygen concentration, and destroys and removes pathogens. Consequently, appetite, stocking densities, feed and growth rates are all enhanced and animal health improved. Used within aquaculture, live seafood holding as well as most public aquariums worldwide, protein fractionators are an essential component within any aquatic life support filtration system. Protein fractionation is effective in seawater, freshwater as well as brackish water systems, within partial or full flow applications.
