Microwave Chemical Reactor Generator

As the reactor was properly constructed and the microwave generator work was synchronised with that of the volumetric pump, microwave energy was directed mostly to the biofilm. It was observed that as a result of microwave radiation the process of organic compounds removal, defined as Chemical Oxygen Demand COD, increased its rate nearly by half.

[PDF] Chemical Reactor Models of Digestion Modulation

In this paper we give an overview of the application of chemical reactor theory to models of digestion processes and indicate how those models extend to eco-physiological questions of modulation of digestion and feeding. In particular, we discuss processes that organisms may use to manage their nutrient intake, including optimality, ecological stoichiometry, and regulatory …
