Abstract:

Processing of petrochemical compounds produces a large amount of wastewater. This wastewater consists of toxic (hazardous) materials that can not be discharged to the environment without treatment. As restrictive environmental constraints increase, new technologies are needed to treat those toxic materials before discharging them to the environment. Wet Air Oxidation (WAO) is one of these new methods.<br>This study casts light on the effect of initial pH on the WAO of benzene at different temperatures and pressures. It was found that at pH 6, a temperature of 260°C and a partial pressure of ox

Abstract:

The Wet Air Oxidation process has considerable attractions for the disposal of toxic organic wastes. In this thesis, a fundamental study is made of the mechanism of oxidation under wet air and related conditions of a series of well-defined substances known to occur as components of industrial wastes, and which are known to present difficulties in the Wet Air Oxidation process. In the initial stages, the oxidation of a series of simple alkylpyridines, namely 2-, 3-, and 4-methylpyridines, has been studied under simulated Wet Air Oxidation plant conditions in a laboratory autoclave operating at

Abstract:

The arsenic maximum contaminant level (MCL) for drinking water is likely to be lowered sometime in 2001 or 2002. If the MCL is lowered, it is speculated that there will be stricter limits imposed on the disposal and handling of arsenic-containing residuals. The purpose of this study is to determine the properties of drinking water residuals, including the chemical characteristics, the amount of arsenic that leaches in common residual handling and dewatering processes, and the hazardous potential of the residuals. Residual samples were collected from seven utilities with high arsenic concentr

The production of municipal solid waste has continued to grow in recent years. In Italy, municipal solid waste production reaches about 29 million tons per year. The organic fraction of municipal solid waste (OFMSW), which accounts for 30-40% of the total waste, usually undergoes biological treatments such as anaerobic digestion or composting, or is incinerated or landfilled. Biological treatments are considered not economically viable due to the long processing time (20-30 days), while incineration and landfilling are considered as low cost but polluting processes.

Abstract:

Global energy demand is predicted to rise in the coming decades, necessitating a shift to renewable energy sources to mitigate greenhouse gas emissions. However, due to the inability to supply renewable energy around the clock, it is estimated that only by adding an important technology, carbon capture and storage (CCS), it could be possible to reduce 80% of the 1990s greenhouse gas emissions. CCS aims to reduce anthropogenic carbon emissions by capturing CO2 from flue gases, transporting, and permanently storing or reutilizing industrially. The CCS approach includes three technologies: post-c

Waste management has become one of the major global environmental concerns of our times associated, as it is, with the consumerist tendencies which fuel the engine of economic growth and environmental impacts. Existing policies in the UK have not yet managed to curb the problem of steadily increasing waste generation despite efforts by Central government and the European Union to set inflexible national targets for waste management. A major problem is that while central government sets the overall goals to be achieved, actual waste collection and disposal are functions of 'local government. In

Food waste is becoming an increasing threat to the environment and the economy. Estimates indicate that annually, a third of the food produced around the world ends up being wasted. Only one-fourth of that food is enough to take nearly a billion people out of starvation. Food waste is especially higher in more developed countries, including most of the states in the European Union and the USA. Sector-wise, food is being lost from field to fork, with households topping the charts.

Toxic contaminants in wastewater from industries have also been increasing therefore development of technologies to remove it have been a great focus of environmental research institutions. In this study, copper waste was recovered from electronic and elec

Abstract:

Mestrado de dupla diplomação com a UTFPR - Universidade Tecnológica Federal do Paraná<br>The efficient treatment of waste plastics and pharmaceutical pollutants is of conspicuous environmental, social and economic benefits. Therefore, here it is approached the application of catalysts that can be efficient in mitigating both environmental problems. In this work, four different catalysts were prepared. Three of them were synthesized by co-precipitation of Ni, Al and Fe nitrates with different mass ratios (5%Ni:95%Al, 20%Ni:80%Al and 10%Ni10%Fe80%Al). The fourth catalyst was prepared by wet

Abstract:

Alternatives to deal with municipal solid waste (MSW), such as mechanical biological treatment (MBT) plants, are a trend. In these plants, the organic matter is digested by anaerobic bacteria, generating biogas and reducing the solid mass, generating simultaneously a solid compost and a liquid leachate as side-streams. The leachate has a complex composition and cannot be treated by conventional wastewater treatment methods, while the compost is mainly used as an agriculture fertilizer, but the amount produced is higher than its demand. This work deals with the valorization of compost to

碩士<br>國立交通大學<br>環境工程系所<br>93<br>In determining a proper waste load allocation for a river, in addition to the relation between pollution sources and the receiving water body, factors such as land uses, catchment areas and population density should also be considered. In this study, the equity and effectiveness of waste load allocations based on different factors were evaluated by the proposed optimization models . The QUAL2E model was used to simulate the water quality variation of the river water body. The Genetic Algorithm was used to calibrate model parameters for improving the quality o

Abstract:

In order to address the growing waste concerns facing South Africa, the Department of Environmental Affairs (DEA) published the National Waste Management Strategy in 2012. The ultimate aim of the strategy is to effect the realisation of the objectives of the National Environmental Management Waste Act (NEMWA). The NEMWA is a sector environmental law based on the waste management hierarchy and its provisions apply to waste management activities in all three government spheres amongst others. The NWMS provides for eight distinct goals with accompanying targets to be met by 2016. Some of these go

Abstract:

MESMEG<br>Department of Mining and Environmental Geology<br>The Mushithe coal occurrence is situated approximately 16 km west of the Tshikondeni coal mine in the Tshipise-Pafuri sub-basin of the Soutpansberg coalfield in South Africa. The Soutpansberg Coalfield has received comparatively less attention compared to other more notable South African coalfields. There is as a consequence very limited information in the public domain applicable to the geology as well as quality of coal in this coalfield, as a result there is no known study focused exclusively on the Mushithe coal occurrence.
