Method for controlling odors in recirculating toilets

Claim 1

A METHOD FOR CONTROLLING ODORS AND INHIBITING GROWTH OF MICROORGANISMS IN RECIRCULATING TOILETS CONTAINING WATER, ORGANIC WASTE MATERIAL AND MICTOORGANISMS WHICH CONSISTS ESSENTIALLY IN: MIXING PARAFORMALDEHYDE WITH THE WATER CONTAINED IN SAID TIOLET, SAID WATER HAVING A TEMPERATURE OF BETWEEN 0*C AND 40*C AND CONTAINING BORAX TO ADJUST THE PH OF THE WATER AND PARAFORMALDEHYDE TO BETWEEN 5 AND 8, THE AMOUNT OF PARAFORMALDEHYDE BEING FROM 100 PART PER MILLION OF 5,000 PARTS PER MILLION, BY WEIGHT, BASED UPON THE CONTENTS OF THE TOILET SO THAT SUFFICIENT PARAFORMALDEHYDE DISSOLVES IN SAID WATER AND SLOWLY RELEASES FORMALDEHYDE TO FORM A SOLUTION AND TO REACT WITH ANY MERCAPTANS, BIOORGANICS AND OTHER COMPONENTS OF HUMAN WASTE CONTAINED IN THE TOILET AND TO INHIBIT THE GROWTH OF MICROORGANISMS WITHOUT KILLING SAID MICROORGANISMS AND THUS NOT INTERFERING WITH SUBSEQUENT BIOLOGICAL DECOMPOSITION ON LATER DUMPING OF THE CONTENTS OF THE RECIRCULATING TIOLET, SAID COMPONENT OF HUMAN WASTE TENDING TO LOWER THE PH OF THE SOLUTION TO THE ACIDIC SIDE THUS INCREASING THE SOLUBILITY OF THE PARAFORMALDEHYDE AND THEREBY PROVIDING MORE FORMALDEHYDE IN SOLUTION FOR REACTION WITH ADDITIONAL COMPONENTS OF HUMAN WASTE WHILE SAID BORAX, WITHOUT REACTING WITH SAID FORMALDEHYDE IN SOLUTION IS TENDING TO RAISE SAID PH ABOVE ABOUT 5 TO CONTROL AND MAINTAIN THE DESIRED CONCENTRATION OF FORMALDEHYDE IN SOLUTION.

Claim 2

A METHOD FOR CONTROLLING ODORS AND INHIBITING GROWTH OF MICROORGANISMS IN RECIRCULATING TOILETS CONTAINING WATER, ORGANIC WASTE MATERIAL AND MICTOORGANISMS WHICH CONSISTS ESSENTIALLY IN: MIXING PARAFORMALDEHYDE WITH THE WATER CONTAINED IN SAID TIOLET, SAID WATER HAVING A TEMPERATURE OF BETWEEN 0*C AND 40*C AND CONTAINING BORAX TO ADJUST THE PH OF THE WATER AND PARAFORMALDEHYDE TO BETWEEN 5 AND 8, THE AMOUNT OF PARAFORMALDEHYDE BEING FROM 100 PART PER MILLION OF 5,000 PARTS PER MILLION, BY WEIGHT, BASED UPON THE CONTENTS OF THE TOILET SO THAT SUFFICIENT PARAFORMALDEHYDE DISSOLVES IN SAID WATER AND SLOWLY RELEASES FORMALDEHYDE TO FORM A SOLUTION AND TO REACT WITH ANY MERCAPTANS, BIOORGANICS AND OTHER COMPONENTS OF HUMAN WASTE CONTAINED IN THE TOILET AND TO INHIBIT THE GROWTH OF MICROORGANISMS WITHOUT KILLING SAID MICROORGANISMS AND THUS NOT INTERFERING WITH SUBSEQUENT BIOLOGICAL DECOMPOSITION ON LATER DUMPING OF THE CONTENTS OF THE RECIRCULATING TIOLET, SAID COMPONENT OF HUMAN WASTE TENDING TO LOWER THE PH OF THE SOLUTION TO THE ACIDIC SIDE THUS INCREASING THE SOLUBILITY OF THE PARAFORMALDEHYDE AND THEREBY PROVIDING MORE FORMALDEHYDE IN SOLUTION FOR REACTION WITH ADDITIONAL COMPONENTS OF HUMAN WASTE WHILE SAID BORAX, WITHOUT REACTING WITH SAID FORMALDEHYDE IN SOLUTION IS TENDING TO RAISE SAID PH ABOVE ABOUT 5 TO CONTROL AND MAINTAIN THE DESIRED CONCENTRATION OF FORMALDEHYDE IN SOLUTION.
