Pijcke, G. (author)The water quality of a 5 hectare lake system in Gardens by the Bay, Singapore is modelled. The lake system comprises two lakes, Dragonfly and Kingfisher Lake, connected by a 5 metre wide stream. Inflow is from runoff from the 50 hectare catchment and from pumping from the neighbouring Marina Bay Reservoir at a rate of 20 Ls-1, 24/7. Outflow is...master thesis 2014

Zhang, S.M. (author)In every society people will inevitably generate unwanted and useless material that is called waste. However, this term is very subjective and inaccurate because most of these materials still contain valuable resources like nutrients and moisture. This research focuses on growing vegetables using the organic waste material and waste water from a...master thesis 2014

Elliott, P.J. (author)Since a few years, more than 50% of people live in urban areas and this number will increase, resulting in major city expanions while facing (potential) problems such as an inadequate access to drinking water, poor levels of sanitation and not enough space for rainwater. Therefore the integration between the water system and architecture becomes...master thesis 2014

Bassin, J.P. (author)The removal of nutrients such as nitrogen and phosphorus from both domestic and industrial wastewaters is imperative since they potentially harm the environment. One of the main consequences of excessive availability of nitrogen and phosphorus in aquatic ecosystems (freshwater, marine and estuarine) is the overgrowth of algae and other aquatic...doctoral thesis 2012

(author)Membrane bioreactors (MBR) are an important and increasingly implemented wastewater treatment technology, which are operated at low food to microorganism ratios (F/M) and retain slow-growing organisms. Enhanced biological phosphorus removal (EBPR)-related organisms grow slower than ordinary heterotrophs, but have never been studied in detail in...journal article 2012

Azab, A.M. (author)The intensive uses of limited water resources, the growing population rates and the various increasing human activities put high and continuous stresses on these resources. Major problems affecting the water quality of rivers, streams and lakes may arise from inadequately treated sewage, poor land use practices, inadequate controls on the...doctoral thesis 2012

(author), Rinaldo, A. (author), Rao, S.P.C. (author)Complexity of heterogeneous catchments poses challenges in predicting biogeochemical responses to human alterations and stochastic hydro?climatic drivers. Human interferences and climate change may have contributed to the demise of hydrologic stationarity, but our synthesis of a large body of observational data suggests that anthropogenic...journal article 2010

Ravazzini, A.M. (author)In the usual wastewater treatment schemes the application of membranes follows a biological process. However, ultrafiltration of untreated wastewater produces permeate free of particles and bacteria in one single step and could represent the starting point for new water-reuse concepts. This thesis focuses on crossflow ultrafiltration of raw...doctoral thesis 2008

De Kreuk, M.K. (author)Most conventional wastewater treatment plants need a large surface area for the treatment of their sewage. This is due to the open structure of the biomass used to convert the polluting components in wastewater. Because of the flocculated growth, sludge concentrations in reaction tanks are low and settling times need to be long in order to keep...doctoral thesis 2006

Laane, R.W.P.M. (author)This report aims to identify the origins of the past changes in the eutrophication status of the Wadden Sea. Special attention is given to changes in light regime, nutrient elimination and retention, which may have resulted from human interventions along the Dutch coast. Starting point for the assessment is that model calculations expect that 10...report 2005

Martins, A.M.P. (author)The activated sludge process is the preferred technology for biological wastewater treatment. Despite decades of progress and operation serious operating problems still occur with this process. One major problem is the regular occurrence of excessive growth of filamentous bacteria, phenomena known as filamentous bulking sludge. Poor solid-liquid...doctoral thesis 2004
