A synergistic composition is provided for controlling odor from waste products. The composition comprises a combination of nitrate salt, sulfide-consuming compound, pH-elevating compound, sulfide-oxidizing, nitrate-reducing bacteria, and sulfide-oxidizing enzyme. The method includes adding a sufficient amount of the composition to a waste stream to provide sufficient sulfide-consuming compound to effect immediate removal of sulfide. The composition incorporates a pH elevating compound, which both decreases the amount of gaseous H 2S and puts the aqueous phase into a pH range where naturally occurring bacteria can more easily metabolize the sulfide.
The composition also includes one or more nitrate salts which will accomplish longer term prevention of odors. Specific bacteria are incorporated into the formulation to insure that the nitrate has the right type and amount of bacteria present to prevent formation of and/or consume sulfide. Specific enzymes are incorporated into the formulation to promote oxidation of sulfide.

Provisional Application No. 60/526,440 filed Dec.
2, 2003 both of these related applications are incorporated herein by reference. FIELD OF THE INVENTION The present invention relates to a method and composition for controlling odors emanating from organic waste produced by metabolic processes, including human and animal waste, as well as industrial wastes, effluents, sewage, and the like. BACKGROUND OF THE INVENTION The biogenic production of volatile compounds which cause objectionable odors is one of the problems associated with the collection and treatment of various waste materials.
Domestic sewage is the largest source of such odorous compounds. Various reduced sulfur-containing compounds are common, with hydrogen sulfide being the most objectionable odor-causing compound in such wastes. Because of the magnitude of domestic sewage that is collected and treated and the prominence of the associated odorous sulfidic compounds, the present invention is particularly directed, but not limited to the control of hydrogen sulfide and other sulfide odors in municipal or industrial waste. As used herein, the term “sulfidic compounds” also includes hydrogen sulfide (H 2S), mercaptans (RSH), and other related odoriferous sulfidic compounds. The mixed biological population common to municipal or industrial waste utilizes the compounds found in the waste as a source of nutrient.
In this process, oxygen is the preferred terminal electron acceptor, and the nutrient, commonly an organic compound, is oxidized. In highly nutrient loaded systems such as municipal sewage, bacterial action can result in a rapid consumption of oxygen in the water. In the absence of oxygen, bacteria require an alternate terminal electron acceptor. In general, bacteria will utilize the terminal electron acceptor that provides them with the greatest amount of energy. Thus, there is a preferred selection order of a terminal electron acceptor by bacteria.
This order is shown below. O 2NO 3 −FeSO 4 −2CO 3 −2 As nitrate is not typically found in natural waters, the sulfate ion (SO 4 −2) is generally the preferred alternate. In the absence of oxygen, unless nitrate is added supplementally, those bacteria which can utilize sulfate as a terminal electron acceptor in their respiration process will predominate. The most well-characterized bacteria of this type is Desulfovibrio desulfuricans, and is most commonly referred to as sulfate-reducing bacteria, SRB. SRB are known to metabolize sulfate ion with organic matter to form H 2S as shown in the following equation. SO 4 −2+organic matter+SRB→H 2S+CO 2+H 2O H 2S, responsible for the characteristic odor from rotten eggs, is toxic in low concentrations.
Citizen complaints are often the driving force behind efforts to control odor. Such odors are generally regarded as a public nuisance and a health hazard. Although H 2S is a gas, H 2S in water can dissociate with increasing pH as shown in the following equations. Thus at a given pH, the relative amount of dissolved H 2S species can be predicted. The sulfide ion, S −2, and bisulfide ion, HS −, being ionic, are constrained to remain in the aqueous phase.
H 2S+OH −→HS −+H 2O HS −+OH −→S −2+H 2O. (H 2S—gas phase & aqueous phase, HS −& S −2 aqueous phase) DESCRIPTION OF FIGURE The FIGURE herein shows the relationship between these species, the evolution of the gas from aqueous solution being a function of pH. At the pH typically found in sewer systems, a significant percent of the H 2S formed evolves from solution. The gas can redissolve on the crown of the sewer line, and the presence of Thiobacillus bacteria and others, metabolize the H 2S, producing sulfuric acid, H 2SO 4. This can and has resulted in sewer line collapse and results in a significant cost in terms of their repair and replacement. H 2S is also corrosive towards steel and concrete. H 2S is a gas, with the evolution of the gas from aqueous solution being a function of pH.

Various compounds, including hypochlorite (sodium or calcium), potassium permanganate, sodium nitrate, ferrous and ferric salts, hydrogen peroxide, chlorine, chlorine dioxide, and sodium chlorite have been widely used for the control of odor in wastes, and sewage waste in particular.

In addition, the use of some sulfide reactive chemicals in combination with nitrates is known: For example, U.S. 3,966,450 cites the use of 5-500 mg/L of hydrogen peroxide and the addition of nitric acid to maintain a pH of 3.5-5.5 to enhance the nutrient value of the waste. 4,108,771 cites the use of chlorate and nitrate coupled with an iron salt in pH.
Remove restaurant odors as well as bar, deli and cafeteria smells with ozone. The OdorFree is a powerful restaurant odor eliminator that will remove restaurant odors and also kill microorganisms such as mold and mildew. The result is a fresh smelling facility and much better dining experience.
Restaurant odor removal is needed because eating and drinking establishments build up odors from the food and beverages they prepare and serve, as well as other factors such as body odors and humidity. Odor causing substances and vapors gets trapped on walls and ceilings, carpet and flooring, furniture and fabrics, as well in the ductwork and a multitude of crevices throughout the facility. And residue from food and beverages also encourages microorganism growth wherever it lands. +How to Treat Restaurant Odors +.
Solution: The best way to remove restaurant odors is to run the OdorFree unit at a high level while the facility is vacant. Let the last person who leaves at night turn the unit on and allow the OdorFree to operate for several hours, oxidizing the odors and reducing microorganism count.
The unit should be set to turn off a couple of hours before reopening. This is the best way to thoroughly remove restaurant smell. Note: The fan on the thermostat for the air conditioner may be turned to the ON setting to circulate the ozone and remove odors that build up inside the ductwork and A/C unit itself. Ozone generators are very effective at restaurant odor removal. As a result, your patrons and staff will have a much better overall dining experience.
Recommended Model for Restaurant Odor Removal The OdorFree Villa 1000 is our most popular model for restaurant odor removal by far. One reason is the convenient 1 to 12 hour timer. This unit is designed for spaces that are unoccupied for several hours or longer during treatment, such as Restaurants, Bars, Delis, Coffee Shops, and other areas where food is prepared and beverages served. The Villa 1000 has a variable ozone output control that will cover up to 4000 sq ft and a timer that can be set from 1 to 12 hours to automatically turn the unit off when the sanitizing is completed.
In addition, a 'Hold' selection on the timer allows for extended treatment (until it is manually turned off) in order to eliminate more deeply ingrained odors. This unit can also be used for smaller spaces if rapid odor removal is needed. The OdorFree Suite 700 can be used for restaurant odor removal in medium sized spaces or smaller food establishments. This model has a variable output control that will cover up to 2000 sq ft and a 1 to 60 minute timer that will automatically turn the unit off when the sanitizing is completed. There is also a 'Hold' selection on the timer so the space can be treated for extended periods (until it is manually turned off) in order to eliminate deeply ingrained odors.
Note: Most customers find the 12 hour cut off timer on the Villa 1000 to be more convenient for treatment at night while closed, and more versatile because it can treat medium and small spaces, as well as larger spaces. The OdorFree Hotel 350 can be used for restaurant odor removal but is designed for much smaller spaces. This model has a variable output control that will cover up to 800 sq ft and a 1 to 60 minute timer that will turn the unit off when the sanitizing is completed. There is also a 'Hold' selection on the timer so the space can be sanitized for extended periods (until it is manually turned off). Note: Most customers find the 12 hour cut off timer on the Villa 1000 to be more convenient for longer term treatments, and the higher capacity unit more versatile because it can treat medium and small, as well as larger spaces. 5 Year Warranty For 5 years from the date of purchase by the original owner, SD International will replace any defective part due to a manufacturing defect at no charge.

These are valid safety concerns because the ozone breaks apart molecules as part of the oxidation process, especially odor causing molecules. It also kills microorganisms like mold and mildew. However, humans and pets are also made up of molecules, so ozone at high levels has the potential to irritate the eyes and respiratory system, especially those with asthma or COPD.
Therefore, ozone should be used with caution. In the recent past, some direct marketing companies sold air purifiers that produce ozone to consumers for use in occupied spaces. This created concern at the EPA, the FDA and the American Lung Association, which resulted in adverse publicity for the ozone industry. For decades prior to that time, ozone had been used commercially in the hotel, apartment, janitorial, water and fire damage remediation industries and many others, while spaces were unoccupied. So the state of California now has ozone restrictions for consumer air purifiers, and industrial ozone cleaners like the OdorFree have special labeling requirements. Beware of any type of air purifier that produces ozone and claims the product is for use in occupied spaces. High Output Claims Sellers on the internet often make false claims regarding the performance of their products in order to obtain a sale.
Beware of sales claims for ozone generators with very high ozone output at a price that seems to be too good to be true. In the event these units were creating the extremely high levels of output claimed, the ozone would be causing unseen damage to vulnerable materials like speakers, leather furniture, electronics and other materials. Once ozone reaches a certain level, degradation and deterioration of materials begins.
Ozone can do great things, but as with any substance, too much or excessive levels will create problems. And extreme levels are not required for permanent odor removal. Technics kn6000 for sale. Safe use and moderation is the key to a successful ozone treatment.
Ozone output levels can vary as a result of air temperature, humidity, barometric pressure and other factors. And there are no set standards or protocols for testing ozone production in milligrams per hour (mg/hr). A high output number is sometimes posted simply to attract buyers. Unfortunately, there is no authority to prevent this type of misinformation from being uploaded and distributed on the web. The vast majority of portable ozone generators sold in the US for commercial use employ ceramic plates. These machines generally produce ozone at output levels of 300 mg/hr to 2,000 mg/hr for the purpose of permanently removing odors.
Mica plates fell into disfavor by most companies decades ago because they were not serviceable. Recently, they have reappeared with internet sellers. Check the Warranty All ozone generators require periodic cleaning of the ozone producing elements to continue operating. Beware of units offered on the Internet that cannot be maintained by the buyer because they will stop functioning after a period of time.
The OdorFree carries a 5 year warranty because it is built to be easily maintained. Many ozone generators have a very short lifespan. Always check the details of the warranty that a manufacturer provides. Ozone can be corrosive and all ozone producing elements build up a film on the plates that dramatically reduces output.
Even plates protected by a filter will build up a microscopic film on the plates over time that causes the ozone production to drop. Beware of ozone plates that cannot be removed and cleaned by the end user. This is especially true of mica plates because the material cannot be cleaned and alignment is very important. So the mica plates have to be permanently built into a handmade assembly for protection.
Thus, the mica assembly can become the most expensive component, by far, in the entire unit. Once the inevitable microscopic film builds up on the mica plates or corrosion occurs, ozone output drops dramatically, making it a throwaway product or requiring a costly return to the factory. The most expensive part in the unit will need regular maintenance but cannot be serviced, so the warranty can become somewhat meaningless.

Remove restaurant odors as well as bar, deli and cafeteria smells with ozone. The OdorFree is a powerful restaurant odor eliminator that will remove restaurant odors and also kill microorganisms such as mold and mildew. The result is a fresh smelling facility and much better dining experience. Restaurant odor removal is needed because eating and drinking establishments build up odors from the food and beverages they prepare and serve, as well as other factors such as body odors and humidity.
Odor causing substances and vapors gets trapped on walls and ceilings, carpet and flooring, furniture and fabrics, as well in the ductwork and a multitude of crevices throughout the facility. And residue from food and beverages also encourages microorganism growth wherever it lands. +How to Treat Restaurant Odors +. Solution: The best way to remove restaurant odors is to run the OdorFree unit at a high level while the facility is vacant.
Let the last person who leaves at night turn the unit on and allow the OdorFree to operate for several hours, oxidizing the odors and reducing microorganism count. The unit should be set to turn off a couple of hours before reopening. This is the best way to thoroughly remove restaurant smell. Note: The fan on the thermostat for the air conditioner may be turned to the ON setting to circulate the ozone and remove odors that build up inside the ductwork and A/C unit itself. Ozone generators are very effective at restaurant odor removal. As a result, your patrons and staff will have a much better overall dining experience. Recommended Model for Restaurant Odor Removal The OdorFree Villa 1000 is our most popular model for restaurant odor removal by far.
One reason is the convenient 1 to 12 hour timer. This unit is designed for spaces that are unoccupied for several hours or longer during treatment, such as Restaurants, Bars, Delis, Coffee Shops, and other areas where food is prepared and beverages served. The Villa 1000 has a variable ozone output control that will cover up to 4000 sq ft and a timer that can be set from 1 to 12 hours to automatically turn the unit off when the sanitizing is completed. In addition, a 'Hold' selection on the timer allows for extended treatment (until it is manually turned off) in order to eliminate more deeply ingrained odors. This unit can also be used for smaller spaces if rapid odor removal is needed. The OdorFree Suite 700 can be used for restaurant odor removal in medium sized spaces or smaller food establishments. This model has a variable output control that will cover up to 2000 sq ft and a 1 to 60 minute timer that will automatically turn the unit off when the sanitizing is completed.
There is also a 'Hold' selection on the timer so the space can be treated for extended periods (until it is manually turned off) in order to eliminate deeply ingrained odors. Note: Most customers find the 12 hour cut off timer on the Villa 1000 to be more convenient for treatment at night while closed, and more versatile because it can treat medium and small spaces, as well as larger spaces. The OdorFree Hotel 350 can be used for restaurant odor removal but is designed for much smaller spaces. This model has a variable output control that will cover up to 800 sq ft and a 1 to 60 minute timer that will turn the unit off when the sanitizing is completed.
There is also a 'Hold' selection on the timer so the space can be sanitized for extended periods (until it is manually turned off). Note: Most customers find the 12 hour cut off timer on the Villa 1000 to be more convenient for longer term treatments, and the higher capacity unit more versatile because it can treat medium and small, as well as larger spaces. 5 Year Warranty For 5 years from the date of purchase by the original owner, SD International will replace any defective part due to a manufacturing defect at no charge.

Simply call 800-683-9749 for authorization and UPS will pick up the unit at no charge to the customer. Call 800-683-9749 for additional information. These are valid safety concerns because the ozone breaks apart molecules as part of the oxidation process, especially odor causing molecules.
It also kills microorganisms like mold and mildew. However, humans and pets are also made up of molecules, so ozone at high levels has the potential to irritate the eyes and respiratory system, especially those with asthma or COPD. Therefore, ozone should be used with caution. In the recent past, some direct marketing companies sold air purifiers that produce ozone to consumers for use in occupied spaces. This created concern at the EPA, the FDA and the American Lung Association, which resulted in adverse publicity for the ozone industry.
For decades prior to that time, ozone had been used commercially in the hotel, apartment, janitorial, water and fire damage remediation industries and many others, while spaces were unoccupied. So the state of California now has ozone restrictions for consumer air purifiers, and industrial ozone cleaners like the OdorFree have special labeling requirements. Beware of any type of air purifier that produces ozone and claims the product is for use in occupied spaces. High Output Claims Sellers on the internet often make false claims regarding the performance of their products in order to obtain a sale. Beware of sales claims for ozone generators with very high ozone output at a price that seems to be too good to be true. In the event these units were creating the extremely high levels of output claimed, the ozone would be causing unseen damage to vulnerable materials like speakers, leather furniture, electronics and other materials.
Once ozone reaches a certain level, degradation and deterioration of materials begins. Ozone can do great things, but as with any substance, too much or excessive levels will create problems. And extreme levels are not required for permanent odor removal. Safe use and moderation is the key to a successful ozone treatment. Ozone output levels can vary as a result of air temperature, humidity, barometric pressure and other factors. And there are no set standards or protocols for testing ozone production in milligrams per hour (mg/hr).
A high output number is sometimes posted simply to attract buyers. Unfortunately, there is no authority to prevent this type of misinformation from being uploaded and distributed on the web. The vast majority of portable ozone generators sold in the US for commercial use employ ceramic plates. These machines generally produce ozone at output levels of 300 mg/hr to 2,000 mg/hr for the purpose of permanently removing odors. Mica plates fell into disfavor by most companies decades ago because they were not serviceable.
Recently, they have reappeared with internet sellers. Check the Warranty All ozone generators require periodic cleaning of the ozone producing elements to continue operating. Beware of units offered on the Internet that cannot be maintained by the buyer because they will stop functioning after a period of time. The OdorFree carries a 5 year warranty because it is built to be easily maintained. Many ozone generators have a very short lifespan. Always check the details of the warranty that a manufacturer provides.
Ozone can be corrosive and all ozone producing elements build up a film on the plates that dramatically reduces output. Even plates protected by a filter will build up a microscopic film on the plates over time that causes the ozone production to drop. Beware of ozone plates that cannot be removed and cleaned by the end user. This is especially true of mica plates because the material cannot be cleaned and alignment is very important. So the mica plates have to be permanently built into a handmade assembly for protection.
Thus, the mica assembly can become the most expensive component, by far, in the entire unit. Once the inevitable microscopic film builds up on the mica plates or corrosion occurs, ozone output drops dramatically, making it a throwaway product or requiring a costly return to the factory. The most expensive part in the unit will need regular maintenance but cannot be serviced, so the warranty can become somewhat meaningless.
