  2. SCU Trace Metal Removal Media Datasheet 6/13/2014

    SCU™ specialty media is a proprietary adsorbent which is similar in appearance to granular activated carbon or anthracite but with a higher density and particle hardness. It removes trace levels of various heavy metals from complex waters to levels not possible with standard ion exchange resins.

  3. Fike Casing Cementing Tool: A Simple Solution 3/17/2014

    The ideal pump-and-plug scenario at a new oil well is a single-stage cementing job performed through the bottom of the casing, with the cement circulating to the top of the target area in the annular space. A uniform layer of cementing is created to support and provide a seal around the surface casing. As a result, drilling can resume.

    The American Society of Civil Engineers grades both wastewater and drinking water systems a D-, the lowest ratings of any infrastructure category, including our aging highways and bridges.

  5. Public Utility Uses Re-Injection Of Treated Arsenic Contaminated Water To Reduce Underground Plume Leaching 6/20/2012

    In December 2009, Evoqua was contacted to treat groundwater for arsenic removal to achieve a 1 ppb goal. The 1 ppb goal limit is equivalent to 10 percent of the current drinking water standard in California and represents the first request at this low treatment goal in the US. The treated groundwater is reinjected on the property to reduce the
    size and mass of the contaminated plume leaching from the property.

  6. Asset Inspections Are Optimal Tool For Maintenance And Capital Improvement 5/22/2012

    Infrastructure asset inspection process is a tool that identifies deficiencies, creates backlog, establishes proactive maintenance, and monitors life cycles; as well as assists agencies in identifying projects for their Capital Improvement Program (CIP). These inspections can provide both a short-term benefit through work identification for repair and maintenance efforts and a long-term benefit of project identification of new capital improvements and enhancement.
