EnvirAnode® is an environmentally focused cathodic protection system. The EnvirAnode® CPS is first and foremost an effective impressed current cathodic protection solution, familiar, but different: Familiar in that an EnvirAnode® CP system is installed using the same tools and techniques as those used in traditional anode beds, though simpler as the vent pipe and anode centring rings are not required. Different in that an EnvirAnode® CP system is constructed from robust extended life AELAnodes embedded in a conductive impermeable column made from specially formulated Conducrete® backfill material. Installed, this configuration transforms into a molecularly bonded tertiary electronic energy transfer system with a very large active surface area over which the CP energy is effectively dissipated into the soil. This results in the ionic reaction boundary being shifted away from the surface of the anode core to the interface between the column and soil, where the large surface area reduces the circumferential energy density, thereby reducing carbon consumption/depletion by nearly half, and extending the life of the anode bed.
Energy transfer efficiency:
The electronic energy transfer mechanism of the EnvirAnode® gives extremely stable electrical operating behaviour in use, especially when compared to the electrolytic energy transfer utilized in traditional anode beds. The large active, low energy density surface area of the EnvirAnode® column causes minute bubbles of gas to be formed over the entire surface of the column, where it is easily absorbed into the soil before it can collect into concentrated pockets. Thus, by better managing the production and dissipation of out-gassing, vent pipes are not required in EnvirAnode® installations and the overall efficiency of the anode bed is increased. Once the EnvirAnode® column has set up, it provides an impenetrable barrier to the migration of water, eliminating aquifer cross contamination to help maintain the quality of critical water resources. The impermeable characteristic continues even after the carbon has been depleted from the active areas of the column, eliminating expensive abandonment issues and costs. The solid EnvirAnode® column also eliminates the “shelving off” phenomenon inside the bore that degrades the anode bed efficiency and shortens operational lifetimes in traditional coke breeze systems.
The EnvirAnode® solution offers more reliable and stable electrical performance (and cathodic protective value) over a longer operational lifetime than any other impressed current cathodic protection solutions currently available. The EnvirAnode® is the world’s first molecular bonded tertiary energy transfer technology developed expressly for cathodic protection applications, and is behind its stunning performance as a fully operational, environmentally neutral cathodic protection anode.
