  Specific Oxygen Uptake Rate: The Fifteen Minute BOD   The goal of this article is: 1.        To introduce readers to the marvelous benefits of the Specific Oxygen Uptake Rate Learn Theory! Learn Theory! Learn Theory! If you know theory you can use it! If you don’t know theory you can’t use it! Thinking in terms of complex systems is difficult. Many people, even after studying for years, do not understand basic principles. Systems thinking is often counterintuitive at many points. It takes many years to gain any degree of skill, and it still often eludes us. (Extraordinary Leadership: Thinking Systems, Making a Difference, 2009, Reberta M.

  Biological Nutrient Removal Basics II   The goal of this article is: 1.        To discuss the purpose of recycle in configurations other than SBRs. 2.        To review inhibiting BNR processes. Learn Theory! Learn Theory! Learn Theory! If you know theory you can use it! If you don’t know theory you can’t use it! (Extraordinary Leadership: Thinking Systems, Making a Difference, 2009, Reberta M. Gilbert, M.D, pg 5) ____________________________________________________________________________________ The last article discussed some basic BNR concepts as it relates to sequencing batch reactors. This article will cover how these concepts can be applied to configurations other than SBR’s. Figure 1 below illustrates the configuration of a 5-Stage Bardenpho Process. FIGURE 1 The 5-Stage Bardenpho Process Recycle The primary difference between an SBR and more conventional configurations is the SBR is di...

Basics of the Biological Nutrient Removal Process   The goal of this article is:   To Introduce the reader to the basic framework of the Biological Nutrient Removal (BNR) Process.  To provide basic guidance in using this basic framework in optimizing and troubleshooting BNR processes.
