Treatment of arsenic-contaminated water using in-line electrolysis, co-precipitation and filtration in Costa Rica
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 active and provided an emergency oxidant. The ...

One process removes arsenic & iron from water in small Utah town
The Safe Drinking Water Act brought with it tough arsenic compliance standards, forcing cities large and small to comply with a maximum contaminant level of 10 parts per billion (ppb) or face stiff fines and even the potential shutdown of wells. Smaller towns such as Cannonville, Utah, face the most difficult challenge, due to manpower and budget constraints. Cannonville turned to Filtronics, ...

A performance assessment of arsenic-iron removal plants in the Manikganj District of Bangladesh
In Bangladesh, arsenic contamination of groundwater, microbial contamination of surface water and seasonally variable rainfall make reliable access to acceptable quality drinking water a challenge. Arsenic-iron removal plants (AIRPs) are a relatively inexpensive way of removing arsenic from groundwater for access to safer drinking water. This study evaluated the performance of 21 (of 105) AIRPs ...

Permanganate Monitoring and Dosing for Drinking Water Treatment
Although an effective treatment aid, residual permanganate in your treated water is undesirable and often leads to consumer complaints when pink water pours out of their tap. Careful control of permanganate dosing can be achieved with real-time permanganate monitoring, resulting in many benefits including: Real-time feedback control to optimize permanganate dose Immediate corrective action to ...

Removal of arsenic and iron removal from drinking water using coagulation and biological treatment
Effects of biological activated carbon (BAC), biological aerated filter (BAF), alum coagulation and Moringa oleifera coagulation were investigated to remove iron and arsenic contaminants from drinking water. At an initial dose of 5 mg/L, the removal efficiency for arsenic and iron was 63% and 58% respectively using alum, and 47% and 41% respectively using Moringa oleifera. The removal of both ...

Monitoring the effectiveness of advanced sorption materials for removing selected metals from water
There are a number of ways to remove heavy metals from water. Sorption on granular media based on iron oxides and hydroxides is currently the most used option. The experiment was carried out using sorption materials GEH, CFH 0818, CFH 12 and Bayoxide, which are primarily designed to remove arsenic from water. Four columns were prepared with an inner diameter of 4.4 cm for the purpose of the ...

Hydraulic residence time and iron removal in a wetland receiving ferruginous mine water over a 4 year period from commissioning
Analysis of residence time distribution (RTD) has been conducted for the UK Coal Authority's mine water treatment wetland at Lambley, Northumberland, to determine the hydraulic performance of the wetland over a period of approximately 4 years since site commissioning. The wetland RTD was evaluated in accordance with moment analysis and modelled based on a tanks-in-series (TIS) model to yield the ...

Desert Sands MDWCA #4, New Mexico - Case Study
In August 2008, AdEdge Water Technologies was contacted by the engineering firm Bohannan Huston to design, supply and start up an arsenic and iron removal system for Desert Sands MDWCA Well #4 in Anthony, New Mexico. The water chemistry had an arsenic level of 17 to 20 ppb and a naturally occurring iron level of 1 mg/L that will facilitate co-precipitation and removal of arsenic. AdEdge was ...

Project profile - Westview Elementary and High Schools Topeka, Indiana arsenic treatment systems
Background In early 2006, AdEdge Technologies Inc. (AdEdge) teamed up with Hawkins Water Tech to design and implement two full-scale arsenic treatment projects for Westview Elementary School and Westview High School located in Topeka, Indiana. Arsenic concentrations in the school wells range between 21 and 23 ppb, which exceeded the new Federal EPA standard of 10 ppb. Design plans were prepared ...

Project profile - Village of Corona, NM iron and manganese reduction
Background In the fall of 2008, AdEdge was selected by Village of Corona, NM to design, manufacture, and startup a water treatment system for the removal of iron and manganese. The water system that serves approximately 100 connections at Corona was plagued by high iron and manganese in the main water supply with iron from 0.26 – 2.8 mg/L and manganese levels from 0.094 - 0.17 mg/L, each ...
