Method and apparatus for stabilizing accumulations in aerated lagoons
Abstract
Abstract IN THE ALTERNATIVE IF THE POOL AERATION IS INCREASED VIOLENTLY THERE IS NO RECIRULATION AND LITTLE ODOR BUT THE VIOLENT AERATION MUST BE MAINTAINED FOR 4 TO 8 WEEKS. A METHOD OF AN AN APPARATUS FOR PURIFYING SEWAGE IN WHICH, THE TEMPERATURE OF THE POOL RISES TO ABOVE 15* C. AFTER A PERIOD OF SOME MONTHS BELOW 10* C. THE FLOW OF SEWAGE IS DIVERTED FROM ONE POOL TO A SECOND POOL. AERATION IN THE FIRST POOL IS EITHER STOPPED COMPLETELY OR, ALTERNATIVELY, VIOLENTLY INCREASED. EITJER METHOD ALLOWS THE WINTER''S ACCUMULATION OF DECOMPOSABLE BUT UNDECOMPOSED MATERIAL TO BE COMPLETELY DIGESTED. IF THE AERATION IS STOPPED COMPLETELY, THIS CESSATION LASTS FOR ABOUT 3 TO 6 WEEKS AFTER WHICH BOTH FULL SEQAGE FLOW AND AERATION ARE RESUMED; PREFERABLY, SOME OF THE COMPLETELY TREADTED LIQUID OUTFLOW FROM THE SECOND POOL IS RECIRCULATED BACK TO THE FIRST POOL-THIS COVERS THE TOP OF THE FIRST POOL WITH A LAYER OF TREATED LIQUID AND REDUCES THE OFFENSIVE ODOR AND ALSO ENSURES A GRADUAL DISPLACEMENT OF LIQUID FROM THE FIRST POOL.
