organic contaminants may be represented by the generic molecular formula CmHnOpNr where m,n,p and r represent integers. the oxidation of an organic may be carried out in two step, carbonaceous oxidation followed by nitrogenous oxidation. determine the value of the stoichiometric coefficient a, b b and d in term of m, n, p and r. give an expressiOn for the theoretical oxygen demand per gram of organic due to carbonaceous oxidation alone (give the answer in unit of gram O2 per gram of organic) Give an expression for the total theoretical oxygen demand (carbonaceous and nitrogenous) per gram of organic Try out your new expression by computing both the carbonaceous and the nitrogenous theoretical oxygen demand associated with 150 mg/L glycine C2H5O2N.

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
