AdEdge Offers Multiple Solutions for Arsenic Contamination

Compliance with the U.S. EPA and the World Health Organization’s maximum contaminant level of 10 parts per billion for arsenic affects thousands of water systems throughout the United States and other countries.

The dangers of arsenic are masked by its colorless, odorless appearance. It is a carcinogen that occurs naturally in groundwater and is known for leading to dangerous health conditions such as cancer, neurodevelopmental disorders and heart failure.

AdEdge offers multiple water treatment solutions rated from 5 gpm to more than 12 mgd. The right option depends upon flow rates, arsenic concentration, the presence of co-contaminants, and site-specific conditions or limitations. Upon receiving a complete water quality analysis, AdEdge determines the best treatment for a plant’s needs based on years of experience and an accurate, predictive model.

Options include adsorption using Bayoxide E33 granular ferric oxide media; coagulation/filtration with iron augmentation; and oxidation/filtration.

Pre-engineered AdEdge Packaged Units are the ideal solution for public water systems, schools, subdivisions and more. The company also offers a line of modular treatment systems that arrive assembled, ready for hook-up. These solutions can incorporate the adsorption, oxidation/filtration and/or coagulation/filtration treatment processes with pre- and post-treatment for a complete integrated system.


In the adsorption process, contaminants break their bond with water molecules and chemically adhere to a filter media. This is accomplished by directing water flow through pressure vessels that contain the adsorptive media at a specific rate that allows the right contact time for adsorption. 

Bayoxide E33 adsorption media is the industry standard for arsenic removal. This granular ferric oxide media reduces up to 99 percent total arsenic, including arsenic (III) and arsenic (V).


Oxidation/filtration is a precipitative process that removes naturally occurring arsenic (if it coexists with high levels of iron), as well as — iron, manganese and hydrogen sulfides. The process oxidizes the insoluble forms of these contaminants into their soluble forms and then removes them via filtration. 

Oxidation/filtration media has a high catalytic and oxidation capacity, superior handling properties, NSF 61-certification, does not require permanganate or coagulant addition, and has low operating and capital costs.


Coagulation/filtration introduces a coagulant, typically an iron or aluminum salt, to pretreat water contaminated with arsenic, iron, manganese and/or sulfides. The process allows for significantly higher flow rates per square foot of media, creates less backwash water than other conventional treatment approaches, and has a smaller footprint that allows for lower operating and capital costs. This process involves chemical addition and automated processes to decrease operator involvement and expense. It does not generate hazardous waste.

AdEdge Water Technologies specializes in the design, development, manufacturing and supply of innovative water treatment solutions that remove contaminants from process or aqueous streams. For more information,
