Abstract Biological reactors are employed in industrial applications to break down organic waste. We view the cascade of two open loop continuously stirred tank with Haldane growth function as chemostats bacterial inputs. A some reactor parameters is derived, sign which determines maximum number critical points a can have. This allows us determine parameter combinations ensure has only single p...

Stirred tanks are widely used in process industries for blending of singleand/or multiple-phase fluids, which often involves mass and/or heat transfer, chemical reactions, etc. Deep knowledge of flow field in the stirred tank is necessary to carry out these unit operations efficiently. As a result, extensive investigations of the flow in stirred tanks have been conducted over the past several d...
