Contaminated Groundwater Treatment - Advanced Iron Removal System - Case Study
Market: Municipality Location: Belleville Ontario, Canada Capacity: 800 m3/day (211,337 gpd) of Groundwater Treatment Installed: 2010 The City of Belleville, Ontario was planning on re-developing downtown waterfront property into a public space containing a park and a green space. Unfortunately, the proposed site had a long history as an industrial site – initially for a coal gasification ...

In-situ biological denitrification using pretreated maize stalks as carbon source for nitrate-contaminated groundwater remediation
A simulation apparatus of in-situ groundwater remediation (SAIR) that used maize stalks pretreated with sodium hydroxide (MSSH) as a carbon source was designed for nitrate-contaminated groundwater treatment. Two experiments, RA and RB, were constructed in this SAIR. The removal performance of SAIR fed with real nitrate contaminated water was investigated under static and dynamic conditions. ...

Bioaugmentation Following ISCO to Remediate TCE in Groundwater - Case Study
Background The chlorinated solvent trichloroethylene (TCE) was discovered in ground water at a manufacturing facility in eastern Massachusetts. ISCO was selected for remediation of the ground water. Although ISCO reduced TCE concentrations, the residual post-ISCO TCE concentrations were above the applicable remediation standards. The environmental consultant chose CL-Out bioaugmentation to treat ...

Industrial Wastewater Solutions Overview
Most industrial facilities produce some volume of wastewater, which can range from 1 gallon per minute to millions of gallons per day. To protect the soil and groundwater from contamination, industrial wastewater treatment solutions must be efficient while meeting environmental standards. Read on to learn more about industrial wastewater treatment processes and what options are available for your ...

Common Treatment Technologies for Explosives in Ground Water, Surface Water, and Leachate
Explosives-contaminated process waste waters can be subdivided into two categories: red water, which comes strictly from the manufacture of TNT, and pink water, which includes any washwater associated with load, assemble, and pack (LAP) operations or with the demilitarization of munitions involving contact with finished explosive. Despite their names, red and pink water cannot be identified by ...

Feasibility of calcium peroxide as an oxygen releasing compound in treatment walls
This research investigates the use of a proprietary formulation of calcium peroxide as an oxygen releasing compound in a treatment wall. Laboratory scale column studies evaluated the release of oxygen and the permeability effects resulting from a mixture of the calcium peroxide and a representative aquifer sand (40-mesh Unimin sand). Influent water was prepared at an average dissolved oxygen ...

Occurrence of water-borne enteric viruses in two settlements based in Eastern Chad: analysis of hepatitis E virus, hepatitis A virus and human adenovirus in water sources
Hepatitis E virus (HEV) is a common cause of water-borne acute hepatitis in areas with poor sanitation. In 2004 an outbreak of HEV infection affected around 2,000 people in Eastern Chad (Dar Sila). This paper describes the decrease in the incidence of acute jaundice syndrome (AJS) from 2004 until 2009 when a mean incidence of 0.48 cases/1,000 people/year was recorded in the region. Outbreaks of ...

Managed aquifer recharge: rediscovering nature as a leading edge technology
Use of Managed Aquifer Recharge (MAR) has rapidly increased in Australia, USA, and Europe in recent years as an efficient means of recycling stormwater or treated sewage effluent for non-potable and indirect potable reuse in urban and rural areas. Yet aquifers have been relied on knowingly for water storage and unwittingly for water treatment for millennia. Hence if ‘leading edge’ is defined as ...

In-Situ Treatment - Funnel & Gate System - Case Study
Problem An asphalt testing facility, in operation for many years, closed in the early 1990s. A subsequent environmental assessment revealed that an underground storage tank, used to hold common cleaning/degreasing solvent for use during testing, had developed a leak and had to be abandoned. The storage tank and soil in the immediate vicinity was removed as the first step to remediate the site. ...

4 Benefits of Electrocoagulation for Groundwater Treatment
Even though groundwater sources are somewhat safer from pollution and contamination due to their underground location, they are still susceptible. A factory may not be able to discharge wastes directly into a groundwater source like they can a surface water stream or river. However, there are many other ways that waste could potentially contaminate a groundwater source. Because soil is ...
