Incidence of endocrine disruption in wild fish species has been documented globally and is well characterised in the UK, where the occurrence of intersex in roach (Rutilus rutilus) is widespread. Although this has been associated with concentrations of steroid oestrogens, resear…
Microalgae are a diverse group of oxygenic photosynthetic microorganisms which show great promise as a source of biofuel. However, significant challenges still remain before microalgae can be considered a viable source of biofuel. The main current challenges are nutrient sourcin…
Reverse Osmosis (RO) is a membrane-based separation process applied in several industrial and food processing applications. In this research, performance of RO process is investigated in respect of two applications (a) wastewater treatment (b) concentration fruit juices using mo…
Improving wastewater (WW) treatment process is a major issue in different parts of the world. For a developed country like the UK where eutrophication is a problem that causes environmental and economical losses, and for a developing country like Jordan that is considered one of…
This thesis covers work carried out on algae bioreactors as a tertiary treatment process for wastewater treatment. The process was primarily assessed by the removal of Phosphorus and Nitrogen as an alternative to chemical and bacterial removal. Algal bioreactors would have the a…
There is a growing deficit between the volume of freshwater used by Israel, Palestine, and Jordan and the volume of freshwater that is jointly available to these countries on an interannual average basis. This deficit has led to myriad adverse consequences, among them the steady…
The objectives of this dissertation were to: 1) characterize the effect of several different silver nanoparticles (AgNPs) on the ammonia oxidizing bacterium (AOB) Nitrosomonas europaea and investigate possible mechanisms for toxicity, 2) test the effects of consumer product AgNP…
Poor public sanitation is one of the principal problems of towns in developing countries. The situation is deteriorating steadily with rapidly advancing urbanization and the lack of adequate infrastructures for the collection and treatment of wastewater. As a result, water-borne…
Among industrial wastewaters, dye wastewater from textile and dyestuff industries is one of the most difficult to treat because of its synthetic origin and complex aromatic molecular structure of dyes. Biosorption using fungi is becoming a promising alternative to replace or sup…
In many coastal systems, freshwater inputs influence the physical and chemical environment of estuarine organisms through changes in flow patterns, salinity, and conveyance of wastewater pollution. In areas with harvestable commercial fishery stocks, freshwater inputs may also p…
A Saudi bentonite natural clay was investigated as an adsorbent for the Basic Blue 3 dye from wastewater. A batch adsorber was used to determine the pore diffusivity and the equilibrium isotherms, and a fixed bed adsorber was used to determine experimental breakthrough curves fo…
