Available in PDF, EPUB and Kindle. Book excerpt: Municipal wastewater treatment using biological nutrient removal generates large amounts of waste sludge. An effort is made to solubilize nutrients from sludge and reuse them in subsequent processes. The microwave-enhanced advanced oxidation (MW/H2O2-AOP) process using hydrogen peroxide as the oxidant was applied to the treatment of different organic slurries including wasted sludge, blood meal, and fish silage. The factors controlling phosphates, ammonia, and COD release into solution included inorganic acid addition, hydrogen peroxide dosage, treatment times and temperatures. Higher dosages and treatment temperatures yielded better solubilization of phosphates and ammonia. It was found that approximately all of the COD was solubilized at a treatment temperature of 80°C. Volatile fatty acid (VFA) concentrations were also found to have increased with the amount of inorganic acid added into treatment. Up to 25% of soluble COD was composed of acetic acid. Higher irradiation levels tended to be more effective in the solubilization of nutrients. In terms of trends of particle size distribution, detectable particles increased in size in acidic conditions, with the largest fraction of larger particles in a given sample being the treatment with highest irradiation power. In neutral condition treatments, the higher the irradiation power provided to the samples, the more spread out the particle sizes range. In alkaline condition treatments, an increase in smaller particles were found after treatment; higher power irradiation yielded significantly higher numbers of smaller particles. This study provided an insight into the athermal effects of theMW/H2O2-AOP. Blood meal solubilization for the purpose of its application as an organic feritilizer was investigated using theMW/H2O2-AOP. It was found that over the treatment temperature range of 60 to l20C, solids particle reduction, ammonia and orthophosphate production were achieved. Maximum solubility of chemical oxygen demand (C.

Available in PDF, EPUB and Kindle. 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.

This book was released on 2020-02-07 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Management of sludge is one of the most pressing issues in sanitation provision. The situation is especially complex when large quantities of fresh sludge containing various contaminants are generated in onsite sanitation systems in urban slums, emergency settlements and wastewater treatment facilities that require proper disposal of the sludge. The application of fast and efficient sludge management methods is important under these conditions. This study focused on the development of an innovative sludge treatment unit that is based on the microwave irradiation technology. The technology provides a rapid and efficient option for sludge treatment in isolated conditions such as slum, emergency, and similar situations. The microwave based technology forms part of the eSOS (emergency sanitation operation system) concept that promotes an integrated sanitation approach in which all components of the entire sanitation chain are planned holistically. Besides, the study addresses the deficiencies associated with the poor choice of emergency sanitation technology options by proposing a methodology that is based on compensatory multi-criteria analysis. This study contributes in providing solutions towards improved sanitation in complex scenarios, especially the management of faecal sludge in emergency and slum conditions.
