Magnesium (Mg2+) makes water hard, which prevents soaps and detergents for working
properly. Therefore, drinking water treatment plants use precipitation to reduce the
concentration of magnesium in the treated water. What pH is required to reduce a high
concentration of dissolved Mg2+ to 25 mg/L? The solubility product for the following reaction is 10−11.16: Mg(OH)2(s) = Mg2+(aq) + 2OH−(aq).

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...
