Sorbster™ Media Properties

• Removal of soluble heavy metals from water by chemisorption

• Bonding at chemically enriched sites throughout enhanced alumina-based media

• High adsorbent capacity: Up to 75% by weight

• Ability to reach ultra low levels (ppb and ppt)

• Effective across broad pH range: pH 3 to 10

• Does not support bacterial growth

• Multi-metal removal in single water pass

• No ancillary waste stream

• Low fouling potential

• Low energy requirement

• Passes TCLP for non-hazardous disposal option

Sorbster™ Adsorbent Media TypesSorbster (Sorbster MM, Sorbster Hg, Sorbster Se)•Multi-metals removal• Selenium Optimized•Mercury Optimized

Sorbster F, Sorbster Cu •Fluoride•Copper

Sorbster Si•Silica

• Water flow is the only control parameter

• Establish water-to-media contact time

• Reacted chemistry provides adsorption sites for both soluble cations and anions

• Aluminum, ammonia and iron sites • rapid bonding of selenite and selenate anions

• Sulfur and oxide sites • rapid bonding of cationic selenium, mercury, cations

Avoid surface active chemistries that can coat surface sites and sustained levels of free oxidants
