Available in PDF, EPUB and Kindle. Book excerpt: Sludge transportation costs can represent a large fraction of the expenses associated with municipal and faecal sludge management. These costs can be mitigated through the use of thermal drying approaches to reduce the sludge volume. This thesis described the application of a novel microwave-based pilot-scale unit as an alternative technology for the sanitisation and drying of sludge from municipal wastewater treatment plants and on-site sanitation facilities. The potential economic benefits of volumetric heating, moisture levelling, and increased liquid and vapour migration from the interior to the surface of the product underpins the increasing interest in the use of microwave technology during sludge treatment processes. According to the findings of this study, these factors lead to faster processing times, improved drying rates, and a reduced physical footprint. Furthermore, microwave technology operates as a standalone treatment unit. When coupled with mechanical dewatering techniques and membrane separation technology, it can increase the reliability of the technology employed in the treatment of sludge while recovering valuable resources through an agricultural or thermochemical application such as (co-) combustion. The results of this work demonstrate the strong feasibility of applying microwave-based technology within initiatives designed to protect the environment and safeguard public health.

Book excerpt: A microwave enhanced advanced oxidation process using hydrogen peroxide (MW/H2O2-AOP) was used for the release of nutrients and the destruction of solids from secondary municipal sewage sludge. The significant factors affecting the MW/H2O2-AOP that would yield maximum soluble substrates were studied. Using a computer statistical software package for experimental design and data analysis, four factors including microwave heating temperature, heating time, hydrogen peroxide dosage, and sludge solids content, were selected and examined. The initial sludge TS content and hydrogen peroxide dosage were the most significant factors for the solubilization of COD and nutrients release under the experimental conditions selected in this study. Overall, the maximum solubilization of nutrients was obtained at 2.5 % of total solids content, 2% of hydrogen peroxide by weight, 5 min. of microwave heating and 120 ðC. The effects of combination of microwave treatment and oxidative reagents on solids destruction and nutrients release were also investigated. Microwave enhanced advanced oxidation processes (MW-AOP), such as MW/O3, MW/H2O2 and MW/H2O2/O3, were conducted at 100 °C. In terms of nutrients release and solids reduction, the MW/H2O2/O3-AOP yielded the best result. Subsequently, three factors including microwave heating temperature, hydrogen peroxide dosage, and ozone dosage, were investigated. The best result, in terms of the release of phosphate and ammonia, and solids reduction, was obtained with additions of 2 % hydrogen peroxide by weight and ozone dosage of 5.09 mg/ml, and operating at 120ðC. About 95%, 32% and 78% of TP, TKN and COD were released into the solution, respectively. The microwave enhanced advanced oxidation processes, with and without an addition of ferrous sulfate (MW/H2O2-AOP and MW/H2O2/Fe+2-AOP), were also studied for reducing solids, and solubilizing nutrients from the secondary sewage sludge. For the MW/H2O2/Fe+2-AOP, the best results of solubilization.

Download or read book Application of Microwave Technology to Effect On site Regeneration of GAC written by K. C. Mahesh and published by . This book was released on 1990 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: The off-site regeneration of granulated activated charcoal(GAC), spent as a result of stripping of organics from aqueous waste streams, represents a burdensome cost both because of the actual cost of regeneration and legal liability associated with shipping a hazardous waste off-site: that liability is reflected in huge potential costs associated with mishaps enroute for the self-insured or high premiums paid to the casualty insurance companies for those generators that are insured by third parties. Thus there is a need for the development of a process to effect on-site regeneration of spent GAC cost-effectively. This thesis mainly focuses on the technical feasibility of microwave treatment to effect regeneration of GAC. This study has shown that microwave treatment of spent GAC can effect the on-site regeneration in a potentially cost-effective process. The regeneration of GAC with an adsorbed organic compound was studied. The compound was a toxic dye, namely, methylene blue. This is a polyaromatic compound containing chlorine, sulfur, and nitrogen atoms. It is a chloride salt. it is non-volatile and decomposes at 190°C. Our experiments showed that GAC with methylene blue adsorbed can be regenerated up to 100%; thus, even when a non-volatile compound is adsorbed on GAC, microwave technology can effect regeneration. The regeneration is effected utilizing microwave technology in a manner consistent with its application on-site, scaled-up. The regenerability of spent GAC was investigated for three successive cycles of adsorption and regeneration. The results showed a good regeneration capacity, even at the end of fourth adsorption and, on an average, 98.2% removal of the adsorbed organic was achieved by microwave treatment. The process appears to proceed by the following stages: water in the GAC pores are directly heated up by the microwaves leading to volatilization; the steam, thus formed, forces the air out of the pores creating an inert atmosphere; the GAC, a strong microwave energy absorber, heats the organic to its pyrolysis temperature; the pyrolyzed organic fuses into the GAC skeleton. This mechanism explains the observed results. More importantly, this mechanism suggests that the most intractable soil contaminants, namely, dioxins and PCBs, can be treated by microwave technology. Assuming that soil and GAC behave similarly, it is possible that the aforementioned contaminants which are polyaromatic compounds will pyrolyze. This investigation is suggested, but not undertaken, in this thesis.
