The TumbleOx™ Bioreactor utilizes an attached growth, non-activated sludge process to provide biological treatment of BOD and ammonia. Media housed in a partially submerged, rotating drum provides a large surface area for biofilm to grow. The unique media design provides aeration as the drum rotates and the media moves in and out of submergence.
IGNITE™ is a non-activated sludge solution for upgrading lagoon based treatment plants to achieve improved BOD and ammonia removal. The process utilizes a combination of Parkson’s Biofuser® lagoon aeration system and TumbleOx™ Nitrification Reactor.
The HiOx® Messner® Aeration Panel provides a unique combination of very high oxygen transfer efficiency with materials of construction that consistently last much longer than conventional fine bubble diffusers.
The EcoCycle SBR™ is a batch treatment process where all treatment steps occur within the same reactor. A typical system includes two or more treatment tanks so as one tank is filling, the other tank(s) are processing and clarifying. A normal treatment cycle will include fill, react, settle, decant, and idle steps.
The VariOx™ Jet Aerator utilizes a combination of motive liquid and blower air to create a highenergy jet plume for mixing and oxygen transfer. The jets can be operated without the blowers or with variable blower input while still maintaining a complete mix condition within the tank. This feature enhances process control and energy optimization.
The DynaCanter™ is a floating style decanter that is used to remove treated effluent (Model ED) or supernatant (Model SD) from the upper portion of the treatment tank. The decanter utilizes a flex joint to allow vertical articulation as water levels change. Water is collected from below the surface to preclude floating material.

Nitrification and denitrification are controlled in the SNDR by monitoring the pH, temperature, and ORP. Since nitrification is inhibited at temperatures above ~100° F, this reactor is operated just under this temperature, in order to fully optimize the growth rate of these specialized microorganisms. pH set points can be used to control the nitrification and denitrification process by creating an aerobic or anoxic condition as warranted. Because a reduction of total alkalinity accompanies nitrification, the pH of the system provides an ideal method of control.
