Data normalization identifies performance issues - Case Study
Introduction The Municipal RO Plant had been in operation for almost 18 years, producing ~290 gpm of permeate water for a city in Iowa, USA. It was one of the first RO plants in the state and the upper mid-west. In May 2008, city operators complained about a loss in system production. In response, the City contracted an RO membrane service provider to perform a cleaning regimen that produced less ...

How NoMonia Works to Treat or Remove Your Ammonia - Case study
Most water utilities should have effective treatment methods for the filtration of arsenic, iron and manganese from drinking water sources. However, as ammonia becomes increasingly concentrated in groundwater throughout the U.S., many utilities around the country are searching for ways to successfully treat the contaminant, while also meeting U.S. Environmental Protection Agency (EPA) standards ...

Project profile - McGraw Hill, East Windsor, NJ iron & manganese removal system
Background In late 2007, AdEdge began working with Maser & Associates to assist with design and implementation of an iron and manganese removal system to serve the water supply for the McGraw Hill data center in East Windsor, New Jersey. The site had an existing groundwater supply well with unacceptably high levels of iron and manganese to serve as feed water for the facilities cooling ...

Project profile - Blue Rhino Hamptonville, NC
Background In 2007, Blue Rhino, located in Hamptonville, NC, contacted AdEdge Technologies, Inc. (AdEdge) to install an iron and manganese treatment system. The amount of iron (5.6 mg/L Fe) and manganese (0.6 mg/L Mn) were well above the maximum contaminant levels of 0.3 mg/L Fe an 0.05 mg/L Mn respectively. The pH of the Blue Rhino site (6.10) was quite below the maximum contaminant level. Blue ...

Georgetown Water Treatment Plant
Georgetown, in the Town of Halton Hills, is supplied by nine groundwater wells located in four well fields. The Region of Halton has received many colored water complaints from customers over the past several years. In order to ensure high quality water to the customers in Georgetown, the Region of Halton retained XCG Consultants to complete two projects. The projects included a study to identify ...

Iron and manganese removal from groundwater by filtration through a chalcedonite bed
The aim of this research was to determine the effectiveness of iron and manganese removal from groundwater using chalcedonite sand as a filter bed in rapid filtration. The experiment was conducted at a pilot plant. At the first stage of research, chalcedonite and silica sand were compared. The ripening time for manganese removal of chalcedonite was 27 days while silica sand was ripened within ...

Decoding the AdEdge treatment matrix
U.S. drinking water utilities come up against a variety of water quality issues. From aesthetic issues to naturally occurring contaminants and contaminants resulting from industry processing, no water source is without problems. Contrarily, many of them have co-occurring contaminants, which complicates the treatment process. Although there is no single treatment solution that will successfully ...

Project profile - City of Moulton, Texas arsenic, iron, manganese treatment system
Background AdEdge Technologies Inc. (AdEdge) was selected by the City of Moulton and Hejl, Lee, and Associates (HLA) to design a full-scale arsenic treatment project using its AD26 and Granular Ferric Oxide (GFO) adsorption technology. In addition to designing the system, AdEdge assisted HLA in obtaining a construction permit from the Texas Commission on Environmental Quality (TCEQ) for the ...

Loch Ascog Water Treatment Works (WTW) - Case Study
Background Loch Ascog WTW, on the Isle of Bute in Western Scotland, treats water abstracted water from the loch. The main treatment at the works was slow sand filtration followed by disinfection. The quality of the treated water was not compliant with the National Requirements of The Water Supply (Water Quality) Regulations 2000 in relation to: Iron and manganese Turbidity and taste ...

Removal of iron and manganese from aqueous solutions using carbon nanotube filters
Carbon nanotubes (CNTs) have become the focus of attention of many scientists and companies worldwide. CNT-based filters have a prospective advantage in comparison to the commercial filters already in operation because they are light weight and do not require electricity to operate. This investigation handles the filtration efficiency of manganese and iron from aqueous solution using ...

The on-site feasibility study of iron and manganese removal from groundwater by hollow-fiber microfiltration
The aim of this research was to investigate the removal of iron and manganese from groundwater by aeration, chlorine oxidation and microfiltration (MF). Pilot-scale experiments were performed at the Chang-Hua Water Treatment Plant in Taiwan. The raw waters contained soluble iron (0.4 mg/L) and manganese (0.5 mg/L) which were oxidized by chlorine and then filtered by hollow-fiber PTFE-MF. The ...
