    Granular Activated Carbon Removes PFOA From Drinking Water

    In the fall of 2015, a small village on the border of Vermont in New York State, tested positive for Perfluorinated Compounds (PFCs), specifically Perfluorooctanoic Acid (PFOA), in the municipal drinking water. The influent levels of PFOA in the water were above 600 ng/L, and thus considered harmful to village residents. Realizing that PFOA was on the U.S. EPA Contaminant Candidate List, the Village solicited the services of engineering firm CT Male Associates to investigate treatment options and provide a treatment system.

RSS Externally Fed Drum Screens RSS Externally Fed Drum Screens

Self-Cleaning Wedgewire Screen
The RSS Externally Fed Drum Screen is a reliable self-cleaning screen for both municipal wastewater operations as well as many industrial applications. This screening technology performs particularly well in wastewater with high oil or grease loadings as well as scum applications that can blind other types of screens.

E33 Adsorption Systems E33 Adsorption Systems

In the adsorption process, contaminants break their bond with the water molecules and chemically adhere to a filter media. This is typically accomplished by directing the water flow through pressure vessels containing the filter media at a rate that allows enough contact time for adsorption to occur. AdEdge Water Technologies’ Bayoxide E33 adsorption media is the industry standard for arsenic removal. This granular ferric oxide media reduces up to 99% total arsenic, including both Arsenic (III) and Arsenic (V).

SHS & SHP Sidehill Screens SHS & SHP Sidehill Screens

Simple And Economical Solids Separation
The simplicity of the SHS and SHP Sidehill Screens make them an excellent choice static screening applications. With no motors or moving parts the Sidehill Screens let gravity do the work as effluent flows down the screening media.  The screening elements are fixed, curved, slotted, wedgewire screens oriented horizontally across the direction of flow. The screening surface is positioned at a steeply sloped angle providing an effective means of quickly stripping of liquid and allowing the solids to slide off the bottom of the screen.
