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 Types
Sorbster (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

Sorbster™ Media Application
Contaminated
Water Stream
• Deployed in industry-standard vessels
• Pump and Treat Application
• Temporary application
• Leased/rented equipment
• Quick contacting time for smaller
equipment footprint & lower capital
cost
Flow
Through
Sorbster
Media
• Water flow rate is the only control
parameter
• Breakthrough determined by
monitoring effluent
• Lead-lag vessels for continuous
operation during change out
