Removal of transition metals from industrial wastewater, groundwater and stormwater runoff

Discontinued product


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 typically not possible with standard ion exchange resins.

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

Once exhausted, spent SCU media can be transferred to Evoqua’s Resource Conservation and Recovery Act (RCRA)-licensed centralized treatment and recovery facility where both non-hazardous and hazardous wastes are treated in compliance with all state and federal guidelines and valuable metals are recycled when possible.
