Instead of smaller molecular weight boiling point of water (100°C)is quite high in comparison to hydrogen teleride(-4°C) and hyrogen sulphide (-62°C). This is because water requires more energy to break its hydrogen bonds before it can then begin to boil. The same concept is applied to freezing point as well.

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...
