AEL ANODE

MMO Tubular Anode Core

AWG #8 cable centerconnected to core

Dual Jacketed, Insulated AWG #8 CablePre-cut to the length defined by the depth of the anode in the EnvirAnode design

Resin filledcore interior

Boot sealing coreto cable

Moulded Surround (95mm x 1825mm)An advanced, specially formulated carbonaceous conductive material designed to resist corrosive environments, water penetration and prolong the operating life of the anode core

End Effect Aging Phenomenon typical of traditional anode cores is delayed until very late in the AEL Anode lifecycle

Sets and forms a solid seal that will not migrate

Seals entire groundbed active zone to protect ground water

Results in electronic transfer of energy into the soil

Dissipates gasses into the soil that would normally be vented to the atmosphere

Conducrete Backfill

Limits the transfer of water Permeability rates are equivalent to bentonite

clay seals Protects the environment by blocking the

open paths to contamination of potable water

In comparison, coke breeze backfills are granular and do not block free water flow

Low Permeability

Hygroscopic Backfill

Water is continuously absorbed into the solid Conducrete backfill

This allows the Conducrete backfill to ride through dry periods better than coke breeze backfills

In extreme dry down hole conditions a casing down to the solid anode column can store water to maintain the absorbed moisture content of the Conducrete backfill

Carbon consumption is half what is published for traditional systems

Carbon consumption is managed in an engineered manner to extend useful life

Life expectancy is twice that of a traditional bed

Low Carbon Loss Per Amp Year

Current Density

The surface area of the conductive backfill column is 10 times greater than the MMO anode

The current density at the interface with the soil is 10 times lower than it is on the surface of a 25mm dia. MMO anode

NO VENT PIPE IS REQUIRED

The Environmental Benefits

Low permeability design inherently protects underground aquifers by sealing against contamination from surface and underground water sources

Anode design effectively manages out gassing to eliminate the need for a vent pipe

No anode bed environmental decommissioning costs as the bed is originally installed as a sealed system

Environmental Issues Eliminating the vent pipe will eliminate these

concerns !

Note: Noxious gases and coke breeze deposits from existing vent pipe

The Technical BenefitsAnode design and installation practices unchanged and even simplified:

Anode design is based on measured soil characteristics like resistivity, moisture and salt content, and current output requirements

Common anode bed installation methods and equipment can be used

Reduced learning curve to deploy the new anode technology

Vent pipes not used Overall benefit: same or lower

design and deployment costs

Surface Groundbeds

Similar to pre-packaged anode concept, but superior as it is precast and does not have the drawbacks of a canister anode

Ultra-low permeability highly conductive AEL anode well suited for wet, high chloride

environments

Summary of BenefitsSuperior technical, environmental and financial

performance High performance electrical characteristics with an extended

lifetime Protection against the contamination of aquifers from surface or

underground sources a major environmental and landowner concern

Environmentally compliant design no vent pipe and noxious gasses at the surface

Flexible and versatile CP tool suitable for new and retrofit anode beds

Elimination of future decommissioning costs and attendant liabilities

All factors contribute to excellent bottom-line performance and ROI

AC Corrosion and Mitigation

Induced AC & AC Corrosion

AC potentials should be below 15 volts for personnel safety

AC corrosion can occur even at AC potentials below 15 volts (current density criteria)

Classic AC Corrosion Pit

Common ROW Today

AC MitigationDe-Coupling Devices

AC Mitigation Installation

Typical Conducrete/copper wireAC Mitigation electrode installation:

A copper core is encapsulated in the Conducrete backfill

When set, the AC Mitigation electrode becomes a single, solid conductor with a large surface area able to safely dissipate large amounts of current

The electrode system protects the copper core from corrosion and deterioration, thus extending the operational lifetime by up to 10 times normal

The entire electrode sets up to provide a mean strength of 3000 psi protects against theft & vandalism
