Wastewater Pretreatment System

CeramTec North America – Laurens, SC


CeramTec is a leader in manufacturing “high-performance ceramics”. The Laurens, SC, facility has been continuously producing technical ceramic products since 1961. These products support automotive, aerospace, cryogenics, high-energy physics, telecommunications, electronics, structural, textile, microwave and nuclear applications. During the manufacture of these technical ceramics, wastewater is generated that is high in metals and Total Suspended Solids. CWS was retained to upgrade and replace the existing pretreatment system with one that would continually meet discharge requirements.
