This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus of this study was to determine the impacts of the digestion of fat, oil, and grease waste (FOG) with the municipal waste. Additionally, a bioremediation product, BioAmp, was used to determine its impact on the stability of the reactors and on biogas yields. The variation of mixed versus settled FOG samples was also investigated for its impact on biogas yields. Ten different reactor compositions were created: sewage sludge, inoculum, before and after BioAmp Treatment with mixed FOG, before and after BioAmp treatment with settled FOG, and co-digestion with these four variations of FOG and sewage sludge. Tests were taken before and after the experiment to determine the characteristics of the samples and stability of the reactors. The reactors were maintained at 35 C for 91 days. Biogas readings were taken daily from each reactor. From these tests we determined that the stability of the reactors was not impacted by fat, oil, and grease. Co-digestion of sewage sludge with FOG proved to have a favorable impact on biogas yields. Actual yields for co-digestion were up to 20% higher than predicted gas production using mono-digestion rates. BioAmp facilitated higher biogas yields. A 42% increase was observed between for the mixed mono-digestion fat, oil, and grease samples after BioAmp treatment. Additionally, the mixed FOG samples provided higher biogas yields than the settled FOG samples. Overall, co-digestion of FOG proved to be feasible and beneficial.

Download or read book Mesophilic Anaerobic Co digestion of Municipal Wastewater Sludge and Un dewatered Grease Trap Waste written by Sedat Yalcinkaya and published by . This book was released on 2014 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fat, oil, and grease residues, food particles, solids and some kitchen wastewaters are collected in grease traps which are separate from the municipal wastewater stream. Grease traps are emptied periodically and grease trap waste (GTW) is hauled for treatment. This dissertation focuses on anaerobic co-digestion of un-dewatered (raw) GTW with municipal wastewater treatment sludge (MWS) at wastewater treatment plants. In particular, this research focuses on the biochemical methane potential of un-dewatered GTW as well as the stability and performance of anaerobic co-digestion of MWS and un-dewatered GTW. A set of modified biochemical methane potential tests was performed to determine the methane potential of un-dewatered GTW under mesophilic conditions (35 °C). Methane potential of un-dewatered GTW in this study was 606 mL CH4/g VS [subscript added] which is less than previously reported methane potentials of 845 - 1050 mL CH4/g VS [subscript added] for concentrated/dewatered GTW. However, the methane potential of un-dewatered GTW (606 mL CH4/g VS [subscript added]) was more than two times greater than the 223 mL CH4/g VS [subscript added] reported for MWS digestion alone. A comprehensive study was performed to determine the stability and performance of anaerobic co-digestion of MWS with un-dewatered GTW as a function of increasing GTW feed ratios. The performance of two semi-continuously fed anaerobic digesters at 35 °C was evaluated as a function of increasing GTW feed ratios. Anaerobic co-digestion of MWS with un-dewatered GTW at a 46% GTW feed ratio (on a volatile solids basis) resulted in a 67% increase in methane production and a 26% increase in volatile solids reduction compared to anaerobic digestion of MWS alone. On the other hand, anaerobic co-digestion of un-dewatered GTW resulted in a higher inhibition threshold (46% on VS basis) than that of dewatered GTW. These results indicate that using un-dewatered GTW instead of dewatered GTW can reduce the inhibition risk of anaerobic co-digestion of MWS and GTW. Recovery of the anaerobic digesters following upset conditions was also evaluated and semi-continuous feed of digester effluent into upset digesters yielded of the biogas production level of the undisrupted digestion. Finally, a mathematical model was used to describe the relationship between methane potential and GTW feed ratio on a VS basis. The results of this research can be used to predict methane production and identify suitable GTW feeding ratios for successful co-digestion of un-dewatered GTW and MWS.

This book was released on 2014-04-30 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anaerobic codigestion of municipal wastewater sludge and restaurant grease was investigated in a semi-continuous lab-scale digestion experiment under mesophilic condition (37 C). Compared to the control digester, COD loading rate for test digester was elevated to 387% (organic loading rate 4.235 kgVS/m3/d) and led to 467% increase in daily biogas production, 25.2% increase in methane yield (based on VS deduction), 29.8% increase in COD reduction rate and 27.2% increase in VS reduction rate, respectively. Methane content ranged from 62% to 67%. There was no negative effect of grease addition on the digester performance in this experiment. The great increases in biogas production and methane yield indicated enhanced digestion performance. In addition, partial alkalinity and pH proved to be good indicators to monitor digestion process and predict overloading. It is still possible to keep increasing organic loading by the addition of more grease, but according to monitoring results, the system was close to overloading.

This book was released on 2012-11-07 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: With petroleum-related spills, explosions, and health issues in the headlines almost every day, the issue of remediation of petroleum and petroleum products is taking on increasing importance, for the survival of our environment, our planet, and our future. This book is the first of its kind to explore this difficult issue from an engineering and scientific point of view and offer solutions and reasonable courses of action. This book will guide the reader through the various methods that are used for the bioremediation of petroleum and petroleum products. The text is easy to read and includes many up-to-date and topical references. This book introduces the reader to the science and technology of biodegradation—a key process in the bioremediation of petroleum and petroleum-based contaminants at spill sites. The contaminants of concern in the molecularly variable petroleum and petroleum products can be degraded under appropriate conditions. But the success of the process depends on the ability to determine the necessary conditions and establish them in the contaminated environment. Although the prime focus of the book is to determine the mechanism, extent, and efficiency of biodegradation, it is necessary to know the composition of the original petroleum or petroleum product. The laws of science dictate what can or cannot be done with petroleum and petroleum products to ensure that biodegradation (hence, bioremediation) processes are effective. The science of the composition of petroleum and petroleum products is at the core of understanding the chemistry of biodegradation and bioremediation processes. Hence, inclusion of petroleum analyses and properties along with petroleum product analyses and properties is a necessary part of this text. Bioremediation of Petroleum and Petroleum Products: Summarizes the pros and cons of remediation of petroleum and petroleum-based products, from an environmental perspective Gives examples of unethical behavior and how they should be corrected Offers arguments and elucidates engineering considerations on all sides of these difficult environmental and economic issues

Download or read book Enhancement of the Mesophilic Anaerobic Co digestion of Municipal Sewage and Scum written by Bradley Young and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Scum is an integral component of solids management in MWWTP and is composed of fats, oils, grease and other entrained floatable materials that are collected during primary clarification. Lab scale BMP tests showed the addition of 14.5 g VS/L of scum exhibited the greatest increase in biogas production of 1.6 times per g VS added compared to the control, while a higher additional scum loading of 33.7 g VS/L reduced the biogas yield to 32% of the control reactor. Lab scale semi-continuous digestion measured the effects of scum loading and temperature of pretreatment in the scum concentrator. At 15 d and 20 d HRTs the greatest observed improvement in biogas was achieved by adding 3% scum by volume and pretreating the scum at 70°C in a scum concentrator with respective improvements of 24% and 16%.

Download or read book The Effectiveness of a Microbial Product to Biodegrade Fats Oils and Grease in Food Service Facility Sanitary Sewer Lines and Grease Interceptors written by and published by . This book was released on 2005 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental case study was performed to investigate the effectiveness of a live vegetative microbial product to completely degrade fats, oils and grease (FOG) in a food service facility grease interceptor, and to assess the economic impacts of potential uses of this product. The case study took place at an Applebee's restaurant located on Niagara Falls Boulevard in Amherst, New York. This investigation indicated increased microbial activity inside the grease interceptor with the use of the product. The thickness of the grease mantle over the three-month baseline monitoring period showed a steady increase. The grease mantle increased in thickness and then leveled off during the three-month product addition period. Comparisons of baseline effluent FOG concentrations and product addition effluent FOG concentrations indicated a statistical difference between the data sets. Although microbial activity seemed to be breaking down FOG in the interceptor, 62% of the effluent FOG concentrations observed during the product addition monitoring period violated the local municipal discharge limit of 100 mg/L. In this particular application where compliance with the Sewer Use Ordinance is judged on effluent FOG concentrations, the use of this product did not achieve results that would be accepted by municipal authorities. For the restaurant to realize a cost savings by using the liquid product, it would have to increase the cleaning frequency of the interceptor to beyond once every 6.3 months. No cost savings was possible with the dry product for the restaurant studied.

Available in PDF, EPUB and Kindle. Book excerpt: Fat, oil, and grease (FOG) in wastewater can cause foul odor, sewer line blockage, and may interfere with sewage treatment. FOG control is approached with physical, chemical, and biological methods Many cities, including Edmonton, Alberta, Canada, have effectively applied commercial biological products to control FOG. Analysis of samples collected from wet wells in Edmonton was undertaken to examine the factors that influence the FOG control performance of commercial biological products. Field sampling showed a seasonal variation of FOG and COD concentrations indicating that the higher temperature in the summer-autumn term compared to the winter-spring term benefited FOG removal. The lowest FOG concentration (49.3 mg/L) was observed when the products were applied with a mixer on in summer-autumn term, which suggests the importance of oxygen and thorough mixing. Based on the results of wet well sample analyses, bench-scale experiments investigated the impacts on FOG removal of product dosage, initial COD, and temperature. Addition of 1000 times the recommended dosage of the commercial products increased FOG removal from 35.5% (achieved at the recommended dosage) to 41.1% in 14 days with an initial COD of 600 mg/L in 14 days. FOG removal increased from 29.8% to 48.0% with an increase in temperature from 15 °C to 32 °C. Suggestions to improve FOG control with commercial biological product application are proposed.
