Siemens offers a broad range of liquid phase carbons to treat industrial, municipal or environmental water applications. We inventory a full line of our premium AquaCarb®, virgin-grade activated carbons made from high quality bituminous coal, coconut shell and anthracite coal raw materials. Liquid applications for activated carbon include improving the taste and quality of drinking water, treating industrial wastewater, purifying materials used in production processes and filtering contaminants out of groundwater at environmental cleanup sites. Our laboratory analyzes and certifies the quality of all activated carbon supplied by Siemens through an extensive QA/QC program.
