1. Ecologically Effective Metals Adsorption Sorbster® Media Wastewater, leachates, ground water, process water, and ponds

2. Sorbster® Media Properties
Functionalized activated alumina technology
High adsorbent capacity: Up to 75% by weight
Ability to reach ultra low levels (ppb and ppt)
Removes both soluble cations and anions in a single pass
Especially effective for soluble metals, silica & fluoride
Effective across broad pH range: pH 3 to 10
Contaminates are permanently bound to the medias
Does not support bacterial growth
Multi-metal removal in a single pass
No ancillary waste stream
Low energy requirement
Passes TCLP/CA WET for non-hazardous disposal options
Bonding at chemically enriched sites throughout enhanced alumina-based media

3. Sorbster® Adsorbent Media Types
Cost Effective Contaminant Removal: 
Simple solution for multiple metals in a single pass
Low CAPEX/OPEX compared to other technologies
• Deploys in industry standard vessels
• Flexible application without hidden costs
• Little operator intervention, minimal training
• Low energy requirement
• Lead-lag vessels for continuous operation during
changeout
• Long media life requiring fewer changeouts
• No activation chemicals
• No ancillary waste streams
• Non-Hazardous disposal reduces waste costs
Sorbster® MM-1
Primarily for Metals
Sorbster® F-1
Primarily for Fluoride
Sorbster® Si-1
Primarily for Silica
Sorbster® Cu-1
Primarily for Copper
Sorbster® Se-1
Primarily for Selenium
Process Dynamics:
Deploy in any tank or cartridge with good water distribution
Water flow is the primary control parameter
Water-to-media contact time is key:
typically 5 to 20 minutes
Sorbster® Medias:
High macroporosity and surface area
Functionalized with specific chemistries throughout each granule to covalently bond contaminants
Density ranges from 45 to 55 lbs./ft3 depending on media type
Avoid surface active chemistries that can coat surface sites and sustained levels of free oxidants
