Canadian Invasion

From our Georgia home base we have easy access to all of the United States, which is where most of our projects have been completed. But we are also no strangers to our neighbors to the north. Here are a few highlights from some of AdEdge’s projects in Canada: 

In Alberta’s Hamlet of Little Smoky community, an AdEdge multi-stage treatment solution tackles high concentrations of arsenic, iron and manganese, aluminum, total dissolved solids, total suspended solids, total organic carbon and turbidity at a truck fill station designed as a resource for residents during times of water scarcity. AdEdge designed a system with ultraviolet disinfection, reverse osmosis, an ion exchange system, an oxidation/filtration system, and pre- and post-chlorination—all housed inside a container. The system, which started in December 2013, runs for approximately 16 hours a day and has a projected consumption of 13,200 gallons per day. Treated water is stored below the system, in a 100-cubic-meter storage tank.

A river mine site in Yukon enlisted AdEdge to treat the arsenic in its tailing pond’s discharge water, as the site’s existing treatment plant was inoperable. The arsenic levels of 54 ppb exceeded the Canadian Metal Mining Effluent Regulations standard of 50 ppb. An AdEdge WaterPOD containerized building houses a skid-mounted coagulation/filtration packaged unit, which has reduced the arsenic levels to well below the standard since it was started up in June 2012.

The approximately 150 students and staff at Rawdon Elementary School in Nova Scotia needed a treatment solution for the elevated arsenic levels in the school’s water. Atlantic Purification Systems contacted AdEdge to design, manufacture and start up a system to bring the arsenic levels to a safe level that complied with the Canadian Maximum Acceptable Concentration (MAC) of 10 ppb. Integrated with the school’s existing water softener system, the 10-gallon-per-minute system is composed of two composite vessels with top mounted automatic flow controls. Using AdEdge’s E33 granular ferric oxide media, the system has successfully and consistently reduced the school’s arsenic levels to below the MAC since September 2007.

From Canada to Argentina to Indonesia, our services are spread across the globe. Give us a call and let us know where our treatment solutions for clean, safe water are needed next.

Small Town, Big Contamination

The village of Dewitt is located in the heart of Illinois, more than 150 miles from Chicago. Although the town has a population of only 200 residents, a number of contaminants had taken up residence in its water supply.

In 2011, Urbana, Ill.-based consulting firm Berns, Clancy and Associates contacted AdEdge to help clean up the community’s water supply. The filter system was not meeting regulatory requirements,with its elevated levels of arsenic, iron and manganese, and hydrogen sulfide. In addition to these contaminants, the water also had high levels of phosphate, ammonia and total organic carbon.

Using a 50-gallon-per-minute treatment system composed of four 24-inch carbon steel vessels arranged in a parallel configuration, AdEdge tackled the contamination. The vessels were loaded with AdEdge’s AD26 oxidation/filtration media for the removal of arsenic, iron and manganese, and hydrogen sulfide. AD26 media is a NSF 61-certified, manganese dioxide-based filter media. The high filtration rate of the AD26 media allows for the removal of the contaminants while maintaining the existing building’s small footprint.

The AD26 media in the presence of a strong oxidant, which is injected into the raw water, acts as a catalyst for the accelerated removal of the contaminants. The programmable logic controller (PLC) initiates an automatic backwash of the treatment vessels to remove any precipitated solids that may accumulate in the media bed and to extend the life of the AD26 media.

Backwashing occurs one vessel at a time to ensure water is continuously being treated throughout the day. The system fully integrates with the existing post-chlorination system that addresses the high ammonia levels in the water before going to distribution.

The system was successfully commissioned in July 2013. Today, it treats more than 30,000 gallons of water each day, reducing each contaminant to non-detectable levels.

AdEdge’s packaged treatment systems are the ideal contamination solution for small community drinking water systems. Contact AdEdge and let us create a cleaner, safer water supply for your customers.
