Sorbster Inc

Sorbster Inc., headquartered in Cleveland, Ohio, manufactures patented specialty adsorbent media for heavy metals and trace contaminant removal from industrial wastewater. The company's core technology — Sorbster Media — is a functionalized, enriched alumina substrate that chemisorbs soluble metals and trace contaminants through covalent bonding at active sites, producing spent media that can pass TCLP testing for non-hazardous disposal. Sorbster's targeted media line includes Se-1 for selenium removal, Hg-1 for mercury, Cu-1 for copper, F-1 for fluoride, MM-1 for simultaneous multi-metal removal in a single pass, and Si-1 for silica, along with the SorbsterClean Crate as a ready-to-deploy plug-and-play treatment solution. The technology was co-developed with the U.S. EPA, providing regulatory confidence for NPDES compliance, and achieves sub-PPM removal with the capability to reach parts-per-trillion levels when required. Key advantages include no activation chemicals or ancillary waste streams, low capital and operating expenditure, minimal operator intervention, long media life, and lead-lag vessel configurations that enable continuous operation during media change-out. Primary applications span CCR (coal combustion residual) streams, FGD blowdown treatment, foundry cooling water, process water treatment, pollutant discharge elimination under the Clean Water Act, dewatering operations, and stripped sour water treatment. The company also offers water diagnostics and testing services, pilot-scale programs, and temporary treatment deployments.
