Facultative Selector or CSTR

The Continuously Stirred Tank Reactor (CSTR) is a floating boom that helps concentrate the oxidation and clarification power of the various systems in a specified diameter.

 

The CSTR works in conjunction with a Blue Frog unit at the lagoon influent, serving as:

The CSTR is also used with a Gold Frog unit downstream to work in the clarification process.



An Equalization Tank that equalizes the influent.

A Selector Tank for preferred indigenous microorganisms that digest sludge in situ.
An Incubation Tank that keeps anaerobes in constant contact with their food source.

The Blue Frog unit is placed in a CSTR (an engineered circumferential baffle) that directs the current flows to increase efficiency.  The Blue Frog unit pushes water out towards the baffle (A), which directs the flow downward and then across the sludge buildup at the bottom of the lagoon. Then the water follows a swirling path back to the Blue Frog inlet.  This flow is called Perimeter Flow.  The net effect is to bring a small amount of Dissolved Oxygen to the sludge surface to increase facultative bacteria activity. Facultative bacteria produce enzymes that turn biosolids (sludge) into simple liquids.  Anaerobes convert simple liquids into gas.  Sludge is digested faster than it is produced and accumulated sludge is digested in situ.
