A field study was conducted at the 55 MGD Dammam wastewater treatment plant employing the carrousel system, to evaluate its overall performance with particular emphasis on nitrogen removal. The results of the study showed that the plant achieved greater than 93% BOD removal, 99%…
Saudi Aramco has operated Ras Tanura landfarm for about 10 years to treat oily sludge. Landfarming is a managed technology which uses soil microorganisms to biodegrade oily waste. Many oil companies in the world have found that landfarming to be the safest, most cost effective a…
This research discusses the delay in public water and sewage construction projects in Saudi Arabia. It studies frequency, extent, and importance of causes of delay in such projects. Sixty causes were identified and classified by source into 6 groups. A field survey was conducted…
A mathematical model which takes into account fill, react and settle periods of the Sequencing Batch Reactor (SBR) was developed and tested against experimental data from the literature. The developed model is capable of predicting microbial cell and substrate concentrations at …
The sludge production rate in the U.S. is increasing rapidly. Effective reduction of sludge mass by solid-liquid separation, though essential, can be a problematic aspect of wastewater treatment. In addition, the fundamental sludge characteristics that affect conditioning and su…
This dissertation presents an examination of the causes and mechanisms underlying the widespread contamination of a shallow groundwater aquifer by fecal bacteria. The context for this study is a field site located in a rural area of Bangladesh that represents a microcosm for the…
Considering the severity of the global water crisis and the enormous backlog of rural communities who lack acces to a clean water source and basic sanitation infrastructure, it is apparent that this incredibly complex problem is one that warrants thoughtful research and implemen…
The narrative production of healthful and diseased environments and populations was a central feature of the nascent Turkish republic’s efforts to distance itself from its Ottoman legacy. In this dissertation, I explore the production of these narratives while paying particular …
The effect of organic loading rates and the solids residence time (SRT) on the aerobic treatment of phenol and o-cresol bearing wastewater by sequencing batch reactors (SBRs) was investigated. SBRs were utilized to treat phenol and o-cresol, aerobically at a hydraulic retention …
The increasing cellulose content of solid waste has been identified as an obstacle in municipal solid waste (MSW) composting. Restricted carbon in cellulose delays the decomposition process, and enhances the loss of nitrogen with the production of odor. Compost stocks were estab…
The recovery of recyclables from the waste stream by human scavengers constitutes a common occurrence in Third World cities. It has been estimated that up to 2% of the poor in many countries make a living by engaging in scavenging. A number of studies on scavenging has been cond…
This study was aimed at evaluating slow sand filtration as a tertiary treatment of secondary wastewater effluents on a pilot scale under field conditions. The wastewater was taken from Al-Khobar Sewage Treatment Plant located in the Eastern Province of Kingdom of Saudi Arabia. T…
Wastewater recharge is one of the most promising techniques currently available to reclaim treated wastewaters. It can play an important part in increasing the use of municipal wastewaters in the Kingdom. However, given the vast number of uncertainties involved in field scale wa…
This study attempts to (i) expand knowledge regarding solid waste management system of Malaysia, particularly the country's landfilling system, and (ii) consider options leading to structural improvements of the country's solid waste landfilling system. The first objective, deri…
Waste management policy to the extent that it qualifies, as management in most Nigerian cities has been disposal oriented. Even when waste is collected from the urban communities, this waste is only to be discarded into open dumps at the edge or in some cases along major highway…
Headloss minimization in slow sand filters is one of the most important considerations for its longer, efficient and economic runs, especially when used to treat nutrient rich secondary effluent. Previous studies on pilot filters have shown complications because of the short fil…
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…
