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.
Ion exchange has historically been a proven technology to achieve metals discharge standards but in most cases has difficulty in achieving effluent levels below 25 ppb, depending on the contaminant and chemistry of the water. With many industries facing new, stricter metals discharge levels, Evoqua Water Technologies has developed SCU specialty media. This new class of adsorbent can routinely achieve effluent levels below 1 ppb for most metals and can achieve levels below 12 ppt (the current US regulation standard for discharge into the environment) for mercury.
