Iquique is an important city in the northern of Chile. For the coast of Iquique a seismic gap with a return period of 111 ± 33 years is present. Since the last big event in 1877 only 20 % of the accumulated seismic slip is released. The configuration of Iquique is such that a large future earthquake and subsequent tsunami would generate a...

This report focuses on the flooding problems in the Lower Moshi area, Tanzania. These floods are the result of the extremely large catchment of the Kilimanjaro region in combination with large peaks in precipitation during the short and the long rainy seasons. The river bordering the area of interest cannot handle these quantities of water which...

This report deals with a method to regulate the releases from a waterreservoir. The researched method makes daily outflow decisions. The method is called the FTAIS method (Fil Tendu en Avenir Incertain Simulé; in English : stretched thread method applied to uncertain future). Scenarios are generated to simulate the future inflows into the...

A proved technique to upgrade (wastewater treatment plant) wwtp effluent to improved water quality is dead-end ultrafiltration (UF). Although the use of UF for upgrading wwtp effluent results in an excellent basic water quality, this technique faces problems due to membrane fouling. Especially particles in the size range between 0.1 and 0.45 @m ...

This report concerning the development of a new water management system in direct tidal swamps with acid sulphate soils with the Pulau Petal area in South Kalimantan as an example. The most important characteristic of acid sulphate soils is that the soil contains the mineral pyrite that oxidizes when the soil is aerated and produces sulphuric...

Ongoing urbanisation and the subsequent extensive use of the urban water system can lead to degradation of its surface water quality. In the Netherlands, urban water bodies often suffer from the manifestations of eutrophication due to (historically) high nutrient loadings. This research focused on the enhancement of surface water quality of semi...

With the development of industry, many new micro pollutants are found in the water sources for drinking water. For instance endocrine disrupting compounds, pharmaceuticals, personal care products, MTBE are reported. However, the conventional water treatment has limited removal efficiency for these components. Therefore, in order to deal with...

WRK III zuivert IJsselmeer water tot een halffabrikaat (coagulatie, sedimentatie, filtratie en gedeeltelijk actievekoolfiltratie) en transporteert dit water naar PWN, voor infiltratie in de duinen, en naar Hoogovens. Bij het transport en zuivering van het water wordt steeds meer gebruik gemaakt van online monitoring en automatische sturing. In...

This report presents a study of the effect of temperature on the sludge in the MBR and on filterability. For three wastewater characteristics the relation with the temperature and filterability is determined: the sludge viscosity, the soluble microbial products (SMP) concentration and the particle size distribution. Chapter 2 attends to the...

Introduction Low Impact Development (LID) is an alternative approach in managing stormwater runoff. Its main philosophy is to replicate the pre-development hydrological properties of water catchment. It seeks to first infiltrate, filter, store and retaining the surface runoff near to its source before draining it to downstream. Some of the...

In this study for a part of Polder 29, one of DDP's pilot polders, it has been determined to which extent the system of channels and structures have a drainage and irrigation capacity which meets the requirements for cultivation of High Yielding Varieties and recommendations have been made how to meet these requirements. Irrigation and drainage...

High concentrations of arsenic in drinking water form a major threat for public health in more than 70 countries worldwide. The situation is Bangladesh is seen as the worst incidence of arsenic poisoning: it is believed that 30 million people in Bangladesh are exposed to an arsenic concentration exceeding 50 ?g/L. Recently subsurface treatment...

Terrestrial water storage (TWS) can be defined as the storage of water on and below the land surface, and includes snow, ice, surface water, soil moisture, and ground water. TWS is a key component of the terrestrial and global hydrological cycles, which have important control over the water, energy and biogeochemical fluxes, and plays a major...

This research focuses on polder-belt canal systems. More is demanded from these systems every day. Man induced changes, like increasing population density and increasing land value on one hand and climate change in the form of longer dry spells and more extreme precipitation events on the other hand are the main sources. The operation of the...

Dunea Duin en Water provides drinking water for 1.2 million people in de western part of the province Zuid-Holland. As a source, for their drinking water production, surface water from the river Meuse is used. Organic micro pollutants (OMPs), although in extremely low concentrations, have occasionally been detected in the river Meuse. Obviously,...

Research performed of the last decades in the waste water treatment field has shown the ability of zeolites to adsorb ammonium via ion-exchange. Recent research has proven that zeolites might also be capable to remove the lower concentrations of ammonium present in groundwater to the for drinking water required standards. This makes it a...

The topic of this thesis is a concept of zero liquid discharge for nanofiltration technology in drinking water treatment. Nanofiltration, defined as a process between Ultrafiltration (UF) and Reverse Osmosis (RO), is a rapidly emerging technology. The origin of NF membranes can be traced back to the late 1950s when it was developed to treat sea...
