Concentrated tests are
required to detect the presence of anions that do not react in
presence of dilute standards. Conc acid will react more vigorously
than a dilute acid in order to see the effect of effervescence. In
the case of precipitation, a proper concentration of the standard
needs to be added in order to achieve the precipitation. Hence
concentrated standards are used to detect along with dilute
standards.

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...
