Book excerpt: Addition of phenol recovery to the wastewater treatment scheme in the Baseline Design for the SRC-I Demonstration Plant was evaluated as a major post-Baseline effort. Phenol recovery affects many downstream processes, but this study was designed to assess primarily its effects on biooxidation and subsequent tertiary treatment. Two parallel treatment schemes were set up, one to treat dephenolated wastewaters and the other for processed nondephenolated wastewaters, a simulation of the Baseline Design. The study focused on comparisons of five areas: effluent quality; system stability; the need for continuous, high-dose powdered activated carbon (PAC) augmentation to the bioreactor; minimum bioreactor hydraulic residence time (HRT); and tertiary treatment requirements. The results show that phenol recovery improves the quality of the bioreactor effluent in terms of residual organics and color. With phenol recovery, PAC augmentation is not required; without phenol recovery, PAC is needed to produce a comparable effluent. Dephenolization also enhances the stability of biooxidation, and reduces the minimum HRT required. With tertiary treatment, both schemes can meet the effluent concentrations published in the SRC-I Final Envivornmental Impact Statement, as well as the anticipated effluent limits. However, phenol recovery does provide a wider safety margin and could eliminate the need for some of the tertiary treatment steps. Based solely on the technical merits observed in this study, phenol recovery is recommended. The final selection should, however, also consider economic tradeoffs and results of other studies such as toxicology testing of the effluents. 34 references, 30 figures and 26 tables.

Book excerpt: Biooxidation is an important part of the overall wastewater treatment system for the proposed SRC-I Demonstration Plant in Newman, Kentucky. After the completion of a Baseline Design for the plant in April 1982, various refinements were evaluated. One of these was the inclusion of a process for phenol recovery from four sour-water streams. As part of this evaluation, an extensive laboratory treatability study was conducted on wastewaters both with and without this phenol recovery step. The purpose of the study was to compare the results of different treatment schemes on different wastewaters and did not include the development of the kinetic coefficients that govern the biooxidation process. Additional treatability testing documented herein, has been performed to establish the kinetic coefficients for biooxidation of the SRC-I wastewaters. This will provide a rational basis for any subsequent changes in design. The wastewater feed used in this study was process recycle water from the Fort Lewis, Washington, pilot plant. Prior to biooxidation, it was pretreated by solvent extraction for removal of phenolics and by steam stripping for removal of ammonia and hydrogen sulfide. Two, 2-stage bench scale bioreactors were operated for approximately eight months, during which time they were stabilized at various steady-state conditions. Kinetic coefficients were evaluated according to the Lawrence and McCarty model, based on BOD, COD, and TOC. Nitrification, oxygen utilization, and solids settling velocities were also studied. The results showed that BOD is a poor basis for the model mainly because almost all BOD5 was removed at all steady-state conditions. Also, the model was more accurate for steady-state conditions of lower solids retention times. The bulk of both organic and ammonia reductions occurred in the first stage reactors.

The remainder of the text discusses toxicity testing in wastewater treatment plants, and the public health aspects of wastewater disposal and reuse. The many advances in wastewater and drinking water microbiology have all been thoroughly integrated into the publication, including: * A new chapter on bioterrorism and drinking water safety * The latest developments in biofilm microbial ecology and biofilm impact on drinking water quality * New, state-of-the-art detection techniques * Expanded and revised treatment of toxicity testing, including new testing methods and studies on endocrine disrupters in wastewater * Alternatives to conventional wastewater treatment New problem sets, which test readers' knowledge, as well as a list of Internet resources have been added to each chapter. In addition, the publication's extensive references have been thoroughly revised for readers who would like to learn more about the latest findings and discoveries on specialized topics. Finally, the color plate section has been expanded and contains many new illustrations and tables. An authoritative guide for all researchers, administrators, and engineers in the field of microbiology, Wastewater Microbiology, Third Edition is also a valuable reference for civil and environmental engineers, public health officials, and students involved in environmental engineering and science.

This area involves both industrial practice and a relatively large amount of advanced coal conversion technology, much of which is on an advanced pilot plant level. It must be emphasized that the report simply identifies representative resources (financial, raw materials, manpower) needed in case a decision is made to achieve given synthetic fuel production rates. The report does not suggest or imply that the resources identified herein, either financial in terms of capital or raw resources in terms of the needed coal mine capacities, are currently available. By simply identifying the critical resources, this report provides a needed data base for decision in the area of synthetic fuels.
