What is MAC?

ToxSorb’s MAC is the result of chemical modification of traditional activated carbon, enabling the removal of a wide variety of inorganic pollutants, while maintaining its original adsorption capability for organic pollutants. Each MAC platform is engineered to have both selectivity and affinity towards a specific pollutant, while ignoring non-essential molecules in the water. This benefit enables MAC to outperform traditional ion exchange systems (i.e. resins) in real-life conditions, where the target pollutant is competing with other ions in the water. ToxSorb's MAC is a proven technology capable of removing pollutants in a wide range of applications including drinking water, industrial & municipal wastewater.

ToxSorb’s MAC technology has been successfully proven to remove the following pollutants: Chromium (Cr), Arsenate (AsO4), Perchlorate (ClO4), Phosphate (PO4), Sulfate (SO4), Nitrate (NO3), Nickel (Ni), Copper (Cu), Permanganate (Mn4O), Zinc (Zn), Cyanide (CN) and Silver (Ag).

ToxSorb’s MAC has received NSF approval for Chromium (Cr), Arsenate (AsO4) and Perchlorate (ClO4) removal in drinking water.

The Innovation

Activated Carbon is a well-established adsorbent for removing organic pollutants from water. However, it is ineffective in removing inorganic pollutants such as heavy metals, perchlorate and nitrates.

In state of the art technologies high adsorbent selectivity is reflected as a double-edged sword. On one hand, selectivity allows for efficient removal of target pollutants from water that usually contain much higher concentrations of competing ions. However, high selectivity makes the regeneration process much harder (higher volumes and salinity of waste brine that needs to be evacuated) and often impractical or economically unfeasible.

The MAC media has a way around this inherent selectivity trade-off; the high selectivity of MAC ensure high removal efficiency, while its ability to catalyze the reduction of the "target pollutant" for example Cr(VI) to Cr(III) during the regeneration stage, makes the regeneration easy and very cost-effective.

ToxSorb's MAC Innovation

  • Enables the highly selective removal of pollutants, resulting a significantly lower filter replacement regime
  • Enables removal of specific inorganic pollutants while maintaining adsorption capabilities for removing organic pollutants
  • Reduces dramatically the regeneration brine required to be evacuated, translating into a major cost saving driver to our clients
