Activated Carbon

HS-AC Activated Carbon

Hydrosil’s HS-AC is a granular activated carbon (GAC) manufactured via high temperature steam activation from selected grades of coconut shell. Hydrosil’s HS-AC is designed for liquid phase applications. The HS-AC is high quality carbon with extraordinary surface area, fine pore structure, high density, and superior hardness. Hydrosil’s HS-AC for treating liquid phase uses macro and micro pore adsorption to remove contaminants. This media is NSF/ANSI 61 certified.

HS-AC is commonly used in oil and gas refineries, municipal drinking water, and industrial pollution control. Industrial projects that use HS-AC include groundwater treatment, stormwater run-off treatment, reverse osmosis systems, and removal of dissolved organics.
