Anaerobic treatment of organic industrial wastes in an artificial lagoon

Claim 1

IN A METHOD FOR THE BIOLOGICAL TREATMENT OF ORGANIC INDUSTRIAL WASTES TO REDUCE THE BOD BY THE ACTION OF ANAEROBIC BACTERIA IN AN ARTIFICIAL LAGOON HAVING A FLOW PATH THERETHROUGH OPEN TO AMBIENT CONDITIONS, SAID FLOW PATH HAVING AN AREA EQUAL TO ABOUT ONE ACRE FOR APPROXIMATELY EACH 500 POUND/DAY OF ORGANIC LOADING, THE IMPROVEMENT OF INOCULATING SAID LAGOON AT AMBIENT TEMPERATURES WITH ANAEROBIC BACTERIA, FEEDING SAID INDUSTRIAL WASTES TO THE INLET OF SAID LAGOON, SAID FEED WASTES AT THE INLET OF SAID LAGOON HAVING A PH OF ABOUT 6.5 TO 7.5, SUBSTANTIALLY CONTINUOUSLY FLOWING SAID INDUSTRIAL WASTES THROUGH SAID FLOW PATH AT AMBIENT TEMPERATURES TO ANAEROBICALLY DIGEST SAID ORGANICS AND DECREASE THE BOD THEREOF, AND CONTROLLING THE FLOW RATE OF SAID FEED WASTES TO MAINTAINED THE ALKALINITY AND VOLATILE ACID RELATIONS OF SAID LAGOON EXPRESSED AS CALCIUM CARBONATE EQUIVALENTS AND ACETIC ACID EQUIVALENTS, RESPECTIVELY, WITHIN THE RANGE OF: (ALKALINITY EQUIVALENTS)-(0.833 VOLATILE ACID SALTS EQUIVALENT)=>ZERO SAID AMBIENT TEMPERATURE BEING FROM ABOUT 25*C. TO ABOUT 5*C., AND THEREAFTER REMOVING THE INDUSTRIAL WASTES OF REDUCED BOD FROM THE LAGOON.
