A sample of water has the following concentrations of ions (and pH = 7.0): cations mg/L anions mg/L Ca+2 40.0 HCO3- 110.0 Mg+2 10.0 SO42- 67.2 Na+ ? Cl- 11.0 K+ 7.0 Assuming no other constituents are missing, use an anion-cation balance to estimate the concentration of Na+ (in mg/L as Na+)? Remember that the balance cannot be in mg/L.

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...
