Groundwater

The morphology, interspace and surface properties of a novel nanofiber membrane are characterized by scanning electron microscopy (SEM), pore percent and contact angle. The membrane, named M-1, is prepared from chloridized polyvinyl chloride by high-voltage electrospinning process. The removals of d

Groundwater in the area of eastern Croatia contains high concentrations of iron, manganese, ammonia, organic substances and arsenic. The appearance of inorganic arsenic in groundwater is mainly caused by arsenic from natural geological sources. Since the groundwater is the main source of drinking wa

Arsenic contamination of drinking water is a concern in many parts of the world. In the United States, the Environmental Protection Agency recently reduced the maximum contaminant level of arsenic in drinking water from 50 to 10 µg/L (ppb). In Bangladesh the arsenic concentration in drinking water c

Jordan has recently given distinguished attention to its single and extremely limited sea outlet — Aqaba. An innovative governing system is being established. Aqaba has been declared as a Special Economic Zone Authority. The main objectives of the new authority are to develop Aqaba as a haven for co

Increases in population and water use are increasing pressures on conventional water sources. The use of alternative sources for non-potable applications can relieve some of this demand. Poor quality ground water, combined with quantities of grey water and rain water, was identified as potential alt

Collaborative work between Thames Water Utilities and PCI–Leopold outlines how pilot trial work has been taken through to full-scale application of a 9 Ml/d, ultrafiltration plant on a “significant risk” Cryptosporidium groundwater source. The pilot plant was subjected to a wide range of feed water
