This work encompasses the study of a novel thermal driven desalination system to accomplish full separation of water and solute. This process advantageous over other process because it involves zero recirculation and zero liquid discharge, thus having minimum environmental impact. Since this system provides full separation, salts and other valuable products can be obtained in addition to pure water. This system can operate at high energy efficiencies using medium temperature heat source like industrial reject or solar cells. This plant consists of two technologies, the full separation and mult

Abstract:

On-site treatment (home and community composting) of organic waste (OW) reduces cost and environmental issues as opposed to centralized facilities and landfilling. By 2025, such on-site practices could reduce costs and greenhouse gas emissions (GGE) by 50 and 40 %, respectively, and save land as compared to maintaining landfilling practices. However, the shift of municipal solid waste (MSW) management systems from landfill disposal to resource recovery requires technological input, population participation and compost quality assurance.

Abstract:

Inadequate sanitation is one of the leading causes of water pollution and consequently illness in many underdeveloped countries, including South Africa and, specifically, the Eastern Cape Province, where cholera has become endemic. As modern wastewater treatment processes are often energy intensive and expensive, they are not suitable for use in these areas. There is thus a need to develop more sustainable wastewater treatment technologies for application in smaller communities. The integrated algal ponding system (IAPS) was identified as a possible solution to this wastewater management probl

Ozonation is used as an alternative disinfection process to chlorination but unfortunately has a potential of oxidizing bromide, a natural component of water sources, to bromate. Bromate is a possible carcinogen with a maximum contaminant level of 10 ppb. To understand bromate formation in full-scale systems, a comprehensive study was conducted at the Moorhead Water Treatment Plant (WTP). Bromide concentrations in source waters were monitored. Water samples from locations in the ozonation chambers were collected and analyzed for bromate and other parameters. Results showed that bromate fo

Dissolved organic nitrogen (DON) in water and wastewater is a major public concern.

BDON in treated wastewater can promote algal growth in receiving water bodies. Understanding biodegradability of DON is important to develop strategies and processes capable of minimizing DON impact on the wastewater effluent receiving water bodies and drinking water.

Biodegradability, bioavailability, and photodegradability are important characteristics of wastewater derived DON and are subjects of research in this dissertation.

The advancement in synthetic chemicals commonly referred to as contaminants of emerging concern (CECs) and their application has led to an increase in environmental pollution. The use of septic tanks otherwise referred to as onsite water treatment systems (OWTS), promotes the introduction of CECs into the environment while allowing little in the way of remediation. In order to study the impacts of CECs from OWTS as they infiltrate the environment and the aquifer system, water, sediment, and vegetation samples were collected around a sinkhole lake surrounded by residential housing using OWTSs.

Abstract:

Man’s impact on the Earth is constantly increasing due to ever progressing technological developments. One of our major impacts is the transportation of organisms to new habitats, leading to alterations of existing ecosystems. Mechanisms responsible for the transportation of marine organisms are mainly associated with the shipping industry e.g. hull fouling, sea chests and ballast water. Ballast water has long been recognised as one of the major mechanisms by which aquatic organisms are transported to new environments. In 2004 the International Convention for the Control and Management of Ship

Abstract:

Oil and gas were recovered from alum shale (black shale) at Kvarntorp, Närke,during a period of 24 years. One of the remnants of this industry is a 100 m highdeposit with high contents of uranium, arsenic, molybdenum, vanadium and otherelements. Presently the leakage of metals from the deposit into nearby streams israther modest but will most likely accelerate in the near future. One way to preventan uncontrolled leakage of these elements from the deposit into the environmentwould be to install a filter with an effective adsorbent that after saturation could easilybe regenerated and reused.
