Get rid of metals
MetalZorb™ sponge provides the ideal technology for reducing and absorbing heavy metals and metallic ions from applications where rapid removal of metals is required, including industrial effluents, landfill leachates, stormwater runoff, and any type of non-point source pollution where unattended gravity flow occurs. MetalZorb is also highly effective for treatment of sludge and slurries derived from industrial processes such as sewage treatment, mine tailings and harbor dredging.
Remote monitoring
This sponge product works well when installed in remote or unattended locations for effective absorption that can be monitored effectively by radio-transmitting sensors.
Easy to use
Sponge cubes can fill a conduit that’s sized for the flow volume at each location or compacted into elongated fishnet bags as absorption units for use within a conduit. When confined in a conduit, they offer little impedance to water flowing through the unit and are not clogged by suspended solids.
Achieve effective ground water remediation by vertically positioning fishnet bags filled with MetalZorb at the gate of a barrier wall funnel system.
Units filled with sponge product can be periodically retrieved and replaced with fresh sponge |

How does it work?
Sponge product consists of multiple highly absorbent half inch cubes, combined in various configurations to address metals removal at any site. Sponge pores are self-filtering to prevent total occlusion of the active polymer component. In some applications, elevated temperatures shorten treatment time. Solvating agents may be added to the slurry to expedite metal transfer from the suspended particles to the sponge. For example, citric or acetic acids can be employed in specific metal-removing applications.
How long does it last?
The duration of treatment and operational lifetime depend upon several factors such as:
- unit size
- cumulative flow volume
- concentration of pollutants of concern
- absorption efficiency of the unit within a specific treatment system
- desired removal efficiency
- consistency of slurry
- average size of suspended particles
For example, a cubic foot of Type M sponge product holds about 190 grams of lead at saturation. If the water to be treated contains 1 ppm of lead, the unit is achieving 100% lead removal and not absorbing anything else, one cubic foot of sponge can treat 50,000 or more gallons of water. At an average flow rate of 1000 gal/week, one cubic foot will last almost a year.
