AdEdge Removes Nitrates in Industrial Application

Whether you require a drinking water, mining, remediation or industrial application, AdEdge can design a system that best fits your needs. Here’s one example of how we rehabilitated the industrial water supply of a Pennsylvania plant.

In July 2011, after a competitive bidding process, AdEdge was selected by CET Engineering Services and a confidential client to design a nitrate removal system for a food processing plant in Lancaster County, Penn. The plant’s raw water had a nitrate level of 14 mg/L, which far exceeded the EPA’s limits. High nitrate levels in drinking water can cause health issues for vulnerable populations, such as pregnant women and the elderly.

“Occasional nitrate levels above the maximum contaminant level (MCL) of 10 mg/L meant that employees had to be provided with bottled water as an alternative to drinking the tap water,” said Peter Lusardi, P.E., BCEE, senior project manager at CET.

According to Lusardi, AdEdge was chosen for the project for their outstanding customer support, high quality materials and affordable pricing.

The unique, custom-designed and manufactured AdEdge system uses the ADNO3 IX resin to bring the nitrate level below the MCL. These spherical beads are incorporated within a portion of the water for treatment. The treated water is then combined with the untreated water to attain a blended nitrate concentration at or below the treatment goal of 8 mg/L.

This system also uses a brine regeneration system, which uses sodium chloride to remove the nitrates from the resin, allowing for years of use. Not only is this a highly efficient method for contaminant removal, it also helps reduce cost and hazardous waste.

And the system has been a huge success. Since the system was started up in December 2011, the nitrate level has been consistently reduced from 14 mg/L to well below the treatment goal.

“The system and water supply are working fine,” Lusardi said. “We are pleased with the results and I would specify [AdEdge’s] equipment in the future.”

Say Goodbye to Sulfide

Does this scenario sound familiar? A customer turns on the faucet, expecting to enjoy a clean, refreshing glass of water. Instead, they are assaulted by the disgustingly familiar scent of rotten eggs. Before long, phone calls are flooding in with complaints about foul-smelling water.

Most likely, you’ve got a case of a hydrogen sulfide contamination. And although hydrogen sulfide is more annoying than it is dangerous, it is not something you want hanging around your drinking water. Luckily, AdEdge can help eliminate this nuisance contaminant and return your water to a state of purity.

Before beginning treatment on any kind of water contamination, a comprehensive water analysis should be performed to determine the type and quantity of the contaminant. Once this is determined, treatment can begin.

AdEdge offers a number of solutions for hydrogen sulfide contaminations. The AdEdge AD26 and AD GS+ media remove hydrogen sulfide, along with a variety of other contaminants, and improve overall water quality—all in one simple process.

AD26 uses an NSF 61 certified solid phase oxidation mineral and can be incorporated with one of AdEdge’s APU, modular or integrated membrane systems. It does not require the addition of unwanted dissolved solids and does not generate any hazardous waste. By administering a low does of chlorine, the removal process is enhanced and the surface of the media is oxidized, preventing the buildup of solids.

The AD GS+ media is a black filter media used for removing hydrogen sulfide, as well as iron, manganese, arsenic and radium. Systems with GS+ may be designed using vertical, horizontal, or open gravity filters and the GS+ is effective at higher operating temperatures and differential pressures than ordinary media.

AdEdge has implemented hundreds of these systems and both are proven to reduce hydrogen sulfide concentrations to non-detectable levels, resulting in clean-smelling water and happy customers.

That rotten egg smell should come from the trash, not your drinking water. Let one of AdEdge’s treatment solutions improve the quality of your water supply.

Improve Water Quality Anywhere With WaterPOD

Water treatment units don’t get much more convenient than AdEdge’s WaterPOD. From a church parking lot, to an industrial park in the middle of the desert, the WaterPOD is versatile enough to travel almost anywhere where improved water quality is a must.

The WaterPOD containerized water treatment unit is a small-footprint, customizable system designed to treat a wide variety of contaminants, including arsenic, iron and manganese, uranium, radium, and nitrates for drinking water, remediation or industrial or commercial applications.

The most challenging site conditions are no match for WaterPOD’s ease of installation and use. Since the WaterPOD is pre-wired, pre-designed and pre-piped, installation is a breeze. Simply place the unit on a level concrete base at your site and you’ve already saved up to 50% in installation costs. The “plug and play” system and simple design allow for easy access to a well or water source hookup, and media is loaded through convenient roof hatches.

Does your site have a lot of custom needs? Would you like an HVAC system or insulation to keep the inside of your unit at a comfortable temperature? No problem. Would you like to enter and exit your WaterPOD with ease, or enjoy the view of your site from the inside of your WaterPOD? Customizable doors and windows are also available. Whatever the requirements, AdEdge can satisfy them with its array of custom options.

Although all installations to date have been permanent, the easily transportable, modular design is also great for temporary applications, such as at remediation sites. It’s the ideal choice for any site where time, money and space are crucial.

AdEdge Wins Montana Project of the Year

Our main goal with any project is always clean, safe drinking water—but a little recognition is always nice too! This past year, AdEdge designed a water system to provide a Montana community access to cleaner, safer drinking water, and that system was recently named the state’s project of the year.

The groundwater system in Great Falls, Mont., had exceeded the acceptable arsenic level since 2004. In 2008, the system, which serves more than 500 people, was placed under an administrative order from the Montana Department of Environmental Quality for its arsenic levels that exceeded EPA standards.

In addition to the possible negative health effects for the community, the water district was about to face large fines for lack of compliance with the arsenic limits. In November 2009, Gore Hill contacted AdEdge to design a treatment system to remove the arsenic and iron from two water treatment plant wells.

At the time AdEdge was brought in, the raw water for Plant #1 had an average arsenic level of 18 ppb and an iron level of 1.39 mg/L and Plant #2 had an average arsenic level of 21 ppb and an average iron level of 4.51 mg/L. To put that in perspective, the EPA’s maximum contaminant levels for arsenic and manganese are 10 ppb and 0.3 mg/L, respectively.

Jason Parris, project manager for the Gore Hill project, explained why arsenic can be such a dangerous contaminant.

“Arsenic is a known carcinogen and is linked to problems with skin and the circulatory system,” he said. “Arsenic in drinking water is at very low levels, but prolonged exposure can lead to these symptoms.”

AdEdge designed two treatment systems, each with a skid-mounted AD26 oxidation and filtration package unit. Each site also received a recycle backwash system that reclaims the backwash wastewater and removes the contaminants as a non-hazardous sludge that can be safely disposed of.

What a difference a year makes! The system was started up in April 2011 and since then, both the iron and arsenic levels have been reduced to non-detectable levels. And AdEdge remains on standby to provide any assistance to the district when needed.

All that hard work paid off. Not only did AdEdge help ensure that the community had clean, safe drinking water, in February, Montana Rural Water Systems honored the Gore Hill Water District with the Outstanding Water Treatment System of the Year award. AdEdge was grateful to be part of that accomplishment.

“AdEdge was very proud of the Gore Hill System,” Parris said. “The contractor and engineer involved did a great job on the design and installation.  The system has been shown off many times by the operators.”

Innovative Design Engineering Combined with Effective Treatment Technologies Solve Today’s Arsenic Removal Challenges.

By Greg Gilles, Vice President and Principal, AdEdge Water Technologies, LLC

Many public water systems in Nevada and throughout the U.S are impacted by the USEPA’s MCL for arsenic.  Over the past 10 years since, the promulgation of this revised arsenic standard, many affected public water systems have deployed a variety of technologies for arsenic removal. The primary technologies for arsenic that have emerged, which are in most common use today, are adsorption, oxidation/filtration, and coagulation & filtration.  Recently, AdEdge Water Technologies completed one of the largest arsenic removal projects of its kind for Spring Creek Utilities, in Spring Creek, NV. The project used coagulation & filtration coupled with an innovative backwash water recycle system to achieve applicable NDEP drinking water standards with zero discharge.  This unique, fast track, high profile project features involved a variety of design considerations, piloting, full scale equipment selection, and integration into AdEdge WaterPOD™ (containerized system) enclosures,  chemical feed requirements,  and residuals handling.   The project was implemented in less than 6 months from start to finish treating three individual well sites with flows of 435 gpm, 725 gpm, and 790 gpm respectively.  

The system features AdEdge AD26 coagulation/filtration technology built into three WaterPOD™ systems. Each system consists of separate, completely packaged, pre-piped, instrumented, and automation, housed inside of 40-feet long x 8-feet customized modular buildings, with combined design flows of approximately 1950 GPM.

AdEdge WaterPOD™ systems combine performance with economy, resulting in an ideal solution for sites where space, cost, and installation schedules are critical. The project also features an AdEdge H2Zero™ backwash recycle system. Included is a vertical backwash holding tank with adequate capacity for temporary storage of the backwash water, controls, flow meter, and pump skid with a control panel. Backwash water is collected, separated and re-processed through the treatment system reclaiming up to 95% of the backwash water with no surface discharge.  In addition, AdEdge AD-IN™ CO2 gas injection modules for pH control to enhance and optimize the arsenic treatment process.

This project truly represents the effectiveness of good design engineering and innovative treatment technologies to solve today’s arsenic removal challenges. For more information contact AdEdge Water Technologies, LLC. 1-866-823-3343  info@adedgetechnologies.com   www.adedgetechnologies.com
