There are many methods available to treat wastewater. Each of the different methods has advantages and disadvantages depending on the characteristics of the wastewater to be treated. Some of these methods are well suited for a variable waste stream while others cannot effectively handle fluctuations in wastewater characteristics. The goal of this project was to develop the preliminary design criteria and order-of-magnitude costing estimate for new facilities to treat the highly variable wastewater from Aldrich Chemical Company. An alternatives analysis of granular activated carbon, biological treatment, UV/Oxidation, and air stripping was performed. Each of the treatment technologies were evaluated based upon the following five criteria: commercially proven technique, effective to meet discharge limits, capital and operating and maintenance costs, secondary wastes generated, and specific advantages and disadvantages. Upon performing the alternatives analysis, granular activated carbon with flow equalization was selected as the treatment technology for preliminary design. It is worth noting that UV/Oxidation, in particular UV-hydrogen peroxide, technologies are very desirable for their ability of eliminating contaminants. This ability allows for pollution prevention and in the end less cost because there are few to no secondary wastes to dispose. However, the UV technologies have their limitations. Highly variable, high strength wastewater with large background UV absorbance does not lend itself well to treatment with UV technology. This is the type of wastewater that is present at Aldrich, and therefore UV technology will not be very effective in meeting discharge limitations. A granular activated carbon system was designed to achieve the discharge limits. The system consists of a flow equalization tank, pH adjustment unit, big filter unit, and carbon unit. The system was designed to minimize carbon usage. A wastewater sampling program was recommended to identify possible sources of contamination that could be reduced to help minimize carbon usage. An Order-of-Magnitude cost analysis was performed. The estimated total capital cost of the system components is $369,000. Operating and maintenance costs are estimated at $701,000 per year. The cost of carbon to treat 5,200,000 gallons a year would be $0.075 per gallon. The net present value of the system for an interest rate of 7% and an equipment lifespan of 20 years is estimated to be $7,626,000.   Copy/Holding information Location Collection Call No. Status   Walter Schroeder Library Master's Theses AC805 .L49 2002 Available Add Copy to MyList Format: HTMLPlain textDelimited Subject:   Email to:
