Arsenic contamination in drinking water resources is of major concern in the Ganga delta plains of West Bengal in India and Bangladesh. Here, several laboratory and field studies on arsenic removal from drinking water resources were conducted in the past and the application of strong-oxidant-induced co-precipitation of arsenic on iron hydroxides is...

The supply of safe drinking water in rural developing areas is still a matter of concern, especially if surface water, shallow wells, and wells with non-watertight headworks are sources for drinking water. Continuously changing raw water conditions, flood and extreme rainfall events, anthropogenic pollution, and lacking electricity supply in develo...

Increasing water scarcity is of growing concern in Europe, especially in Mediterranean countries along coastlines. Wastewater reuse reduces water stress, but often requires the absence of pathogen indicators and the application of chlorine to assure residual disinfection. However, the effluent qualities of typical Wastewater Treatment Plants (WWTP)...

Reliable data on the economic feasibility of small-scale rural water supply systems are insufficient, which hampers the allocation of funds to construct them, even as the need for their construction increases. To address this gap, three newly constructed water supply systems with water points in Nepal, Egypt, and Tanzania were accompanied by the au...

A large variety of Advanced Oxidation Processes (AOPs) to degrade trace organic compounds during water treatment have been studied on a lab scale in the past. This paper presents the combination of inline electrolytic chlorine generation (ECl 2) with low pressure UV reactors (UV/ECl 2) in order to allow the operation of a chlorine-based AOP without...

Natural water treatment techniques combined with engineered solutions were investigated at demonstration sites in Europe within the AquaNES project. Ultrafiltration is well-established in water treatment, but is not feasible for many water utilities due to its high operational costs compared to conventional treatment. These differences in cost are...

The present study was conducted to treat primary and secondary treated sewage for its reuse in irrigation, soil enrichment and aquaculture activities. The study involves treatment of this sewage through a subsurface horizontal gravity-fed gravel filter bed with an area of 35 m². The effluent was then subjected to filtration by zeolite medium and di...

Marketing Report: The marketing report will focus on regional needs in Europe, Asia and Africa and market options for combined systems with special focus on cost savings. It will highlight favourite design practices and adaption strategies for the combination of BF with en-gineered solutions in order to secure water supply under extreme weather con...

SWINGS was a cooperation project between the European Union and India, aiming at implementing state of the art low-cost technologies for the treatment and reuse of domestic wastewater in rural areas of India. The largest wastewater treatment plant consists of a high-rate anaerobic system, followed by vertical and horizontal subsurface flow construc...

A novel treatment was tested with groundwater to investigate its arsenic removal under natural conditions. The system utilised in-line electrochlorination to oxidise water constituents without the need for external chemical supply. The oxidised arsenic and iron co-precipitated and were filtered via Greensand Plus™. The filter was catalytically acti...

Addressing the lack of viable solutions for water treatment in small rural communities, this paper describes the test of a system for the removal of arsenic. The SuMeWa|SYSTEM (AUTARCON GmbH) disinfects water using in-line electrolysis for the production of chlorine. In order to remove arsenic this approach has been extended using chlorine as oxida...

Currently India lacks of proper wastewater treatment facilities and in general the existing ones are not properly operated and are not producing safe waters for discharge nor reuse. An FP7 DST-EU financed project, Safeguarding water resources in India with green and sustainable technologies (SWINGS), aimed at building 4 effective and reliable water...

Safeguarding water resources in India with green and sustainable technologies- (SWINGS)” is a project in the framework of cooperation between the European Commission and India Department of Science and Technology. The project aims at developing decentralized low cost optimized treatment schemes, employing state of the art wastewater management and...

India as the rest of world as a result of climate change and overexploitation of resources is facing a water crisis. Although over the past decades the Indian government has made improvements as regards availability and quality of water, the subcontinent is on track to become the world's most populated country in less than a decade, therefore incre...

Safeguarding water resources in India with green and sustainable technologies-(SWINGS)" is a project in the framework of cooperation between the European Union (EU) and India DST. The project aims to develop decentralized low cost optimized treatment schemes, employing state of the art wastewater management and treatment systems to make full use of...

Safeguarding water resources in India using green and sustainable technologies (SWINGS) is a collaborative project funded by the European Union FP7 program and the Department of Science and Technology of the Government of India, whose aim is to implement low-cost sustainable technologies for wastewater treatment and reuse in rural areas of India. T...

Safeguarding water resources in India using green and sustainable technologies (SWINGS) is a three year cooperation project between European and Indian partners aimed at providing and applying treatment wetland technology in India through cooperation. The project calls for the constructing of two large wastewater treatment facilities. Both plants a...

This paper presents the outcome of a study that has led to the development of a fully autonomous solar driven drinking water disinfection plant for remote developing regions. It discusses the background of water supply in remote regions and the challenges of safeguarding the water from pathogenic contamination for public health assurance. For these...

Der Ausstieg aus der Kernenergienutzung und die Erfüllung von erforderlichen Klimaschutzzielen sind simultan nur zur erreichen, wenn der Ausbau erneuerbarer Energien und verstärkte Anstrengungen im Bereich der Energieeffizienz und des Energiesparens parallel verlaufen. Trotz der unbestrittenen und entscheidenden Bedeutung dieses Zusammenhangs sind...
