Arsenic Removal from Groundwater using Ferric
Arsenic is a carcinogenic metalloid that is currently regulated in drinking water. The levels of arsenic in finished water in an existing water treatment plant are exceeding the current regulation of 10 μg/L. One of the available technologies for arsenic removal from groundwater is adsorption onto coagulated flocs and in this field, ferric chloride is the most commonly used coagulant for arseni...
متن کامل1 Arsenic removal from groundwater using iron
10 11 We demonstrate that electrocoagulation (EC) using iron electrodes can reduce arsenic 12 below 10 µg/L in synthetic Bangladesh groundwater and in real groundwater from 13 Bangladesh and Cambodia while investigating the effect of operating parameters that are 14 often overlooked, such as charge dosage rate. We measure arsenic removal performance 15 over a larger range of current density tha...
متن کاملRemoval of arsenic from groundwater by electro-ultrafiltration
The objective of this study was to examine the removal of arsenic from groundwater by a laboratory scale electro-ultrafiltration (EUF) system. Two groundwater samples taken from I-Ian County located in the northeastern part of Taiwan were studied. These well waters were selected based on their As(III) and As(V) contents; the As(III) to As(V) ratios of the well water were 1.8 and 0.4 for Well-#1...
متن کاملCarbon Nanotubes Technology for Removal of Arsenic from Water
Aims of the Study: This study was aimed to investigate the adsorption mechanism of the arsenic removal from water by using carbon nanotubes in continuous adsorption column. Materials & Methods: Independent variables including carbon nanotubes dosage, contact time and breakthrough point were carried out to determine the influence of these parameters on the adsorption capacity of the...
متن کاملRemoval of methylated arsenic in groundwater with iron filings.
Field and laboratory experiments were conducted to study the potential use of Fe filings to remove monomethyl arsenate (MMA) and dimethyl arsenate (DMA) from contaminated waters. Batch experiments show that the affinity of MMAfor Fe filings is comparable to that of inorganic arsenate, but lower than that for arsenite. In contrast, very little DMA was retained by Fe filings or their corrosion pr...
