Abstract
An apparatus to be used in a process for bioelectric neutralization of a body of water having a bottom of anaerobic mud and an acid supernatant liquid, the apparatus comprising a buoy riding on the surface of the water, and upper electrode preferably of carbon suspended from the buoy in the acid supernatant liquid, a lower electrode preferably of iron embedded in the anaerobic mud and a flexible, insulated electrical conductor preferably an insulated copper cable, conductively attached to the upper and lower electrodes. A plurality of sets of apparatus may be used spaced apart from each other in the body of water.
