This review aims to discern a treatment for grey water by examining grey water characteristics, reuse standards, technology performance and costs. The review reveals that the systems for treating grey water, whatever its quality, should consist of processes that are able to trap pollutants with a small particle size and convert organic matter to mi...
The emerging cleantech market in China will bring new business opportunities for Swedish cleantech SMEs (Small and Medium Enterprises). In such an internationalization process, business network building is an important approach that Swedish entrepreneurs should consider about. Guanxi is a culture pattern in China and plays important role in busines...
Vision on eco-innovation in our society and the role of technology in it.
This course explores recent historical and anthropological approaches to the study of life, in both medicine and biology. After grounding our conversation in accounts of natural history and medicine that predate the rise of biology as a discipline, we explore modes of theorizing historical and contemporary bioscience. Drawing on the work of histori...
Aerobic wastewater treatment is energy and resource intensive. As a consequence, the accessibility of clean water is closely related to the availability of energy. Interestingly, wastewater itself is a source of chemical energy, indeed 1 kg of carbohydrates corresponds to roughly 4 kWh of energy. The question is how to convert the chemical energy i...
Preventing climate change and protecting our natural resources are among the key challenges of our times, and we need innovative environmental technologies to tackle them. In Germany today, the environmental technology industry is already an essential part of the economy, and it is bound to become even more important in the future."GreenTech Made i...
This article presents possible renewable energy technologies (RET) for energy recovery from waste water worked out on the example of two model regions of Vietnam.
Environmental reform by (inter)governmental agencies, private firms and industries and non-governmental organizations (NGOs) is a worldwide phenomenon. This definitive collection showcases an introduction to Ecological Modernisation Theory; state-of-the-art review essays by key international scholars and a selection of the key articles from a quart...
Photochemical removal of NO by 172-nm Xe2 excimer lamps (50 or 300 mW/cm2) was studied at 1 atm. In a batch system, NO could completely be converted to N2 and O2 in N2, and N2O5 and HNO3 in air after about 30 min irradiation using a 300 mW/cm2 high-power lamp. NO could also be decomposed in a flow system using the high-power lamp. The conversion of...
Nieuwe sanitatiesystemen gebaseerd op scheiding van geconcentreerde en minder geconcentreerde huishoudelijke afvalstromen aan de bron komen zowel internationaal als nationaal steeds meer in de belangstelling. Verschillende uitvoeringsvormen zijn mogelijk. Dit artikel beschrijft het resultaat van onderzoek dat is uitgevoerd door Tauw en WUR/LeAF bij...
