The proposed site for a deep anode system should avoid low or flood-prone locations, areas where surface contaminants are probable, or locations involving containment dikes or structures. Although site selection is an important consideration, the upper portion of the deep anode system should be properly sealed regardless of the location, since rainwater runoff can carry pollutants into the system. Although the surface sealing requirements for deep anode systems may vary depending upon the specific state or other enforcement agency involved, most authorities require a surface seal of from 3 to 8 meters (10 to 25 feet) of cement, cement-grout, concrete, bentonite, or bentonite-cement mixtures.
Were in deep anode systems. K. S. 2. The most common platinum thicknesses range from about 1 to 8 microns (50 to 300 microinches). Although these anodes are available in wire, rod, plate, and mesh form, the most common arrangement for deep anode systems is wire with some rod anodes used in higher current applications. 8 i n c h e ~ ) . ~ " . ~ ~ - ~ ~ Platinum-coated anodes have been used successfully when surrounded by carbon backfill. 3 X where the evolution of chlorine gas is the primary reaction.
The accumulation of excessive gases can isolate sections of the anode surface from contact with the carbon backfill (gas blockage) resulting in increases in contact resistance and anode discharge current density. These problems with gas blockage can be reduced by limiting the anode discharge current density, selection of a high-conductivity carbon backfill, and use of a properly designed venting system. The necessity for a venting system increases as the anode diameter decreases and discharge current density increases.
