Method for controlling algae pollution
Abstract
Abstract WATER IN PONDS, AQUARIA, STREAM AND OTHER OPEN SYSTEMS AND THE LIKE EXPOSED TO LIGHT IS SUBJECTED TO ELECTROLYSIS WITH ELECTROCHEMICALLY INERT ELECTRODES OR WITH AN ELECTROCHEMICALLY ACTIVE ANODE AND AN ELECTROCHEMICALLY INERT CATHODE TO DESTROY OR TO CONTROL THE GROWTH OF ALGAE. A CURRENT DENSITY IS MAINTAINED AT A LEVEL HIGH ENOUGH TO DESTROY THE ALGAE, AND LOW ENOUGH TO BE HARMLESS TO HUMAN AND FISH LIFE. WHEN AN ACTIVE ANODE IS USED IT RELEASES METAL IONS TOXIC TO ALGAE, AND A DETECTOR ELECTRODE IS USED TO SENSE THE TOXIC ION CONCENTRATION SO THAT A PREDETERMINED CONCENTRATION LETHAL TO ALGAE IS MAINTAINED. ESSENTIALLY THE SAME SYSTEM MAY BE USED FOR THE DESTRUCTION OF BACTERIA, SCH AS E. COLI, R. RUBRUM, CHROMATIUM, AZOTOBACTER, R. RUBRUM MUTANT (R-26). AND THE LIKE.
