Patent ID: 8524080

Claim:
An apparatus process for purifying water containing contaminants selected from the group consisting of cyanotoxins, bacteria, viruses, parasites, positively and negatively charged ions, and radiation, comprising: (a) a reactants tank arranged to receive and hold a quantity of said contaminated water, a bottom portion of said reactants tank containing a plurality of spaced-apart electrodes, (b) high-voltage means for pulsing two of said spaced-apart electrodes in said bottom portion of said reactants tank with a first direct-current electric field of at least 10,000 volts/cm for at least 0.1 second at least once while said quantity of contaminated water is in said tank to destroy said cyanotoxins, said bacteria, said viruses, and said parasites, (c) low-voltage means for applying tank a second direct-current electric field to two of said spaced-apart electrodes in said bottom portion of said reactants tank while said quantity of contaminated water is in said tank so that one of said two electrodes receiving said direct-current field is negatively polarized and the other of said two electrodes receiving said direct-current field is positively polarized, said electric field being at least 3 volts/cm and lasting for a duration of at least one minute so as to separate positively charged contaminant ions from negatively charged contaminant ions so that said positively charged ions are sequestered near said negatively charged electrode and said negatively charged ions are sequestered near said positively charged electrode, and (d) a carbon filter in an upper portion of said reactants tank for removing radiation from said water in order to provide potable water, whereby said cyanotoxins, said bacteria, said viruses, said parasites, said positively and negatively charged ions are reduced in said contaminated water so that said water is no longer contaminated and is potable.
