Sorbster™ Media for Water Treatment Wastewater, leachates, ground water and ponds
. All rights reserved MAR Systems Inc.

2. 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

3. 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
