<br />I 231<.. <br /> <br /> <br />F. Treatment Alternatives. <br /> <br />Evaluate three future treatment and effluent discharge alternatives. Include <br />the following items in the evaluation of each alternative. <br /> <br />1. Based on projected wastewater quality and quantity, Owner <br />preferences, and the three treatment scenarios, identify alternatives to <br />meet the respective effluent criteria. <br /> <br />2. Identify type, number, capacity, size, and loading rate for major <br />process components. <br /> <br />3. Develop process flow schematics for each alternative showing <br />process components, pumping stations, and points of chemical feed. <br /> <br />4. Identify existing and potential areas of odor generation and <br />describe appropriate odor control measures to be provided. <br /> <br />5. Develop preliminary opinion of probable construction cost and <br />operation and maintenance costs. <br /> <br />6. Identify implementation schedule. <br /> <br />7. Prepare a working paper summarizing the information developed in <br />this task. <br /> <br /> <br />G. Evaluate Sludge Management Alternatives. <br /> <br />1. Evaluate sludge thickening processes for the primary sludge and <br />secondary sludge prior to stabilization. <br /> <br />2. Evaluate sludge stabilization processes and dewatering processes. <br /> <br />3. Review state and federal regulatory requirements and evaluate final <br />sludge disposal alternatives. It is anticipated that three alternatives <br />will be identified and evaluated. <br /> <br />4. Prepare preliminary opinion of probable construction cost and <br />operation and maintenance costs for the alternatives. <br /> <br />5. Prepare a working paper summarizing the information developed in <br />this task. <br /> <br />H. Effluent Reuse. <br /> <br />Evaluate the potential for effluent reuse. <br /> <br />1. Identify effluent requirements for various reuse options. <br /> <br />2. Discuss various options with the City and identify one option to be <br />evaluated. <br /> <br />3. Develop process flow schematic showing process components and <br />points of chemical feed. <br /> <br />06/02/93 <br /> <br />A-4 <br /> <br />
