Homework Answers
There are lots of techniques, industry used to estimate the reaction rate. Some of them are described here for different situations.
1. The reaction rate is calculated using the formula rate = Δ[C]/Δt, where Δ[C] is the change in product concentration during the time period Δt.
2. The rate of reaction can be observed by watching the disappearance of a reactant or the appearance of a product over time.
3. If a reaction produces a gas such as oxygen or carbon dioxide, there are two ways to measure the reaction rate: using a gas syringe to measure the gas produced or calculating the reduction in the mass of the reaction solution.
4. If the reaction produces a precipitate, the amount formed can be used to determine reaction rate by measuring how long it takes for the forming precipitate to obscure the visibility of a cross through a conical flask.

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...
