Effect of hydrodynamic cavitation on disinfection of Escherichia coli was investigated in laboratory scale device. The cavitation was generated using a rotor, driven by a simple milling cutter, in the thin layer of water which was circulated from and to a reservoir. Disinfection efficacy was analyze

Although current microbial risk assessment models assume that microorganisms are randomly dispersed within drinking water samples, experimental findings indicate that ‘clumping’ or clustering of microorganisms is possible. Research results indicate clustering is positively correlated with turbidity.

A visible light driven photoelectrocatalytic fuel cell (PECFC) recently developed at Aberdeen has been shown to have the capacity to oxidatively degrade a wide range of contaminants commonly found in water supplies and associated with risk to human health. It has also shown great potential to kill h

In many places world wide drinkable water is already a scarce good and its lack will rise dramatically in the future. Missing energy sources and no grid connections complicates the use of standard desalination techniques in these places. Fraunhofer ISE develops solar thermally driven compact desalin

Water scarcity is a major problem in many developing countries. Depending on precipitation intensity rainwater constitutes a potential source of drinking water. In addition, its proper management could reduce water and food crisis in some of these regions. Rainwater harvesting (RWH) is a technology

Recent efforts aimed at minimizing membrane fouling have emphasized an increasing demand for on-line monitoring in an effort to accurately predict membrane performance. To this end, an in situ bacterial monitoring system was developed that is integrated within the membrane. Because the target is bac

Emergency water treatment approaches relying on coagulation vary from centralised modular and portable ‘‘kits’’ to ‘‘pointof-use’’ or ‘‘household’’ interventions. Typical coagulation practice in emergencies is reviewed in view of field constraints (e.g. equipment and resources) and contrasted with u

Water provision for developing countries is a critical issue as a large number of lives are lost annually due to lack of access to safe drinking water. The presence and fate of inorganic trace contaminants is of particular concern. Trace inorganic contaminants have been found in elevated concentrati

This study looked at two arsenic removal technologies, method Bucket Treatment Unit and removal using citrus lime, lemon and filter. The method Bucket Treatment Unit used zero-valent iron and removal using citrus lime, lemon and filter used photochemical oxidation of arsenic. The citrus lime, lemon

Access to a sufficient quantity of water of adequate quality for human consumption is a global problem. Nowadays, among the 1 billion people estimated to lack access to improved water sources and sanitation worldwide, rural populations are disproportionately underserved. As a consequence, sustainabl
