The natural resources in Ethiopia are under intense pressure as a result of population growth and inappropriate farm practices. Introducing alternatives could be a step forward in reducing the impact of farming on natural resources. In Ethiopia, the pressure on water bodies and land is high which results …

Mild steel is the main material of alloys in use. Approximately 20% of corrosion damage of metals is induced by bio corrosion. The aim of this research was to study the corrosion performance of mild steel and stainless steel when immersed in natural seawater. In order to verify the effect of the microorganisms …

Constructed wetlands are one type of Sustainable Urban Drainage System (SUDS) that have been used for decades in The Netherlands. They provide stormwater conveyance and improve stormwater quality. European regulations for water quality dictate lower and lower concentrations for an array of dissolved …

With increasing world population, more wastewater is produced which all need purification treatment. Removal of pathogenic organisms is important because they can cause problems to human health. This experiment will focus on the removal of human bacterial pathogens. The problem of human bacterial pathogens …

In dit afstudeerrapport is gepoogd antwoord te krijgen op de vraag hoe innovaties om bodemdaling in het Groene Hart te reduceren in gang kunnen worden gezet. In het onderzoek is gekeken naar de mogelijkheden die er zijn om innovaties die als doel hebben de bodemdaling in het veenweidegebied te reduceren, …

An estimated 17 million tonnes of tires are discarded annually. Re-use is achieved by retreading (9%), recycling (39%), energy recovery (37%) and landfill (5%). A preferred, but complex way of recycling is to make new tires from discarded tire rubber. Vulcanised car tire rubber has to be devulcanized …

Dealing with the issue of urban storm water flooding is becoming increasingly urgent. In the Netherlands there are no clear guidelines on the level of acceptance of urban flooding. Based on an accurate DEM, a detailed quick scan tool has been used to assess an extreme storm event in Amsterdam. The resulting …

Het aantonen of corrosie gedetecteerd kan worden in de omtrek richting van pijpleidingen. Er wordt gebruik gemaakt van zeer dispersieve akoestische plaatgolven genaamd Lamb waves. Als transducers worden er Elektro-Magnetische Akoestische Transducers gebruikt. Corrosion inside pipelines caused by salt …

Waterborne diseases are posing a constant threat for people. In developing countries there is a lack of microbiologically safe drinking water and in the developed countries there are occasional waterborne disease outbreaks. These diseases are caused by bacteria or parasites which can be found in various …
