Arsenic

Arsenic is a serious problem in groundwater in Bangladesh, West Bengal, and other regions, with up to 100 million people worldwide estimated to be at risk. Long term consumption leads to arsenicosis, skin lesions and cancers. There is a clear need for cheap, simple, non-toxic field test kits for rou

Arsenic in drinking water is a factor that has recently been shown to be a possible cause for an elevated bladder cancer risk in northern New England. More than 40% of the population in this region uses private wells as the primary drinking water source. Point-of-entry (POE) and point-of-use (POU) a

The potential of enhancing As(III) removal was investigated in a pilot study for the process of oxidation, precipitation and direct sand filtration as pretreatment before ultrafiltration. The pretreatment effectively facilitated As(III) removal and residual arsenic was below 10 µg/L for membrane eff

The present work dealt with the characterization and treatment of liquid wastes produced during the hydrometallurgical recovery of germanium (Ge) from fly ash. The main metals causing reasons for environmental concern were arsenic (As), nickel (Ni) and antimony (Sb). Precipitation using calcium hydr

The city of Malgara in the municipality of Aksios, in northern Greece, relies on local groundwater for the municipal water supply. The groundwater has pH 7.9 and contains elevated concentrations of arsenic (20 µg/L), phosphate (550 µg/L), manganese (235 µg/L) and ammonium (1.2 mg/L), whereas the iro

In the last years, boron and arsenic are gaining wide attention in the water treatment community due to their adverse effects both on human/animal health and on agriculture. As a consequence, nowadays, the number of water treatment plants equipped with boron and arsenic removal facilities is growing

Management of hazardous wastes, such as arsenic, is one of major public concern. Arsenic is a naturally occurring metalloid, which is widely distributed in nature. Recently, arsenic in drinking water attracted attention because some of the drinking water resources contain considerable concentrations

Arsenic removal from drinking water is a major problem in many parts of the world. We have investigated arsenic removal by flocculation and microfiltration. Ferric chloride and ferric sulphate have been used as flocculants. The use of small amounts of cationic polymeric flocculants, as flocculation
