    Dependable waste water deodorizer
    By (Joplin) [6.12.2020]
    I used Odoreze® Natural Waste Water Odor Treatment Additive in our waste water evaporator. I tested out a small bottle first because my only concern was foaming but it was not a problem because the foam subsided after initial mixing with water. As a deodorizer, Odoreze is quite good.

    Effective on Sludge Odors, Suitable for Big Treatment Plants
    By [11.28.2019]
    We used Odoreze® Eco Wastewater Odor Treatment Additive & Spray Concentrate in our wastewater treatment facilities in Canada. Very effective in dealing with set concentrations of ammonia and H2S odors. Another useful application of this cost-effective concentrate is diluting it and spraying in sludge and the airspace above the odor causing liquids stored in our storage facility. Very happy with Odoreze!

    Cost effective, efficient concentrate to treat effluent smell
    By (Dalonega) [9.18.2019]
    I work for a wastewater treatment plant. We dry our sludge using a centrifuge, then stock pile our dried sludge in a pole barn. For help with the odors, we switched to Odoreze a few months back and it proved excellent for the musty odor that our sledge tends to develop sometimes. We mist the solution on the barn and the sledge and it eliminates the odor molecules. Good product for commercial use.

    Odoreze Successfully Eliminated Chemical Odor from Our Fogger Device
    By (Bloomington) [8.2.2019]
    We use a Fogger Device that uses water to create a mist. A pulse pump injects the odor chemical into it. We were hoping to get rid of the scent so we decided to use Odoreze™ Wastewater Odor Treatment Additive and it worked. Quite an effective and pocket-friendly solution that is totally plant based too.

    Smell in Sewer Ejector Room Neutralized!
    By (Philadelphia) [7.17.2016]
    There is a long open drain that fills with water when it rains and leads to the sewer ejector room which is in a basement with no windows. Although we ran a dehumidifier all the time, this area and the offices adjacent to it stunk all the time! I wanted it to smell better so I added Odoreze™ Effluent Odor Control Additive to the drain that fills with water to stop it from reeking. Secondly, I simply placed Smelleze® Industrial Smell Deodorizer Pouches in both the basement and adjacent offices. Mission accomplished!

    Neighbors Stopped Complaining About Treatment Plant Odor
    By (Oklahoma City) [8.14.2015]
    We were having severe sludge odor issues during our dewatering and drying processing step at our waste water treatment facility. Consequently, we were getting frequent complaints form our residential neighbors. We tried tweaking the process several times but that didn't help. We tried some commercial products but they didn't help either. So we hired a reputable waste water consultant to help us. In addition to some technical recommendations, he suggested incorporating the use of Odoreze™ Eco Waste Water Odor Eliminator Spray into our dewatering and drying process. Apparently, he had good success with using this deodorizing product elsewhere. We accepted his proposal and implemented the new process. We were pleased to learn that the sludge smells were reduced to below detectable levels. We have maintained these levels for six months now and that has stopped all odor complaints. In fact, we have received compliments for listening to our neighbors and fixing the problems.

    Safe Environmentally Friendly Ingredients

    The Odoreze™ Wastewater Odor Control Spray is a biodegradable, non-toxic and non- flammable deodorizer. It is made entirely from safe naturally derived ingredients. Odoreze™ does NOT contain hazardous air pollutants, ozone depleting substances, phosphates, nitrates, nonyl phenols, carcinogens, fragrances, dyes, alcohols, caustic, ammonia, chlorine bleach, quats, silicates, chlorinated solvents or petroleum distillates. It is a high performance odor control product without the environmental, health and safety issues associated with conventional deodorizers containing harmful synthetic chemicals.  Furthermore, all ingredients are approved by the FDA (Food & Drug Administration) under 21 CFR-172.510 and FEMA 3121 and on the GRAS (Generally Regarded as Safe) list. Odoreze™ meets and the toughest regulations in existence today making it safer for all and provides an ideal green solution for eliminating wastewater odors without adding pollutants to the environment.

    Sustainable Wastewater Odor Solution

    Odoreze™ is made from all natural renewable resources and reduces the carbon footprint. By focusing on supplying a super concentrated product, packaging waste is significantly reduced which makes a positive impact on landfills. This also reduces the energy expanded to transport ready to use liquid deodorizers which can consist of as much as 95% water! And what is good for the planet is also good for you because a super concentrated product ends up saving you money without compromising quality!

    How Odoreze™ Controls Wastewater Odors

    The Odoreze™ Wastewater Odor Control Spray utilizes state of the art biotechnology and works in a uniquely effective manner to eliminate wastewater odors. Firstly, it immediately binds to the odor causing molecules such as organic acids, hydrogen sulfide and ammonia to destroy them. Secondly, it inactivates the enzyme urease which converts nitrogen and urea to noxious and unpleasant smelling gases like ammonia. Thirdly, it destroys odor producing anaerobic bacteria and promotes the growth of friendly aerobic odor destroying bacteria. Odoreze™ does not merely mask wastewater odors, it truly eliminates them and prevents their formation using the Deodorizing Power of Nature.


    Odoreze™ Wastewater Odor Control Spray can be effectively used to eliminate the wide variety of odors generated in municipal and industrial wastewater facilities.


    The following directions apply to municipal and other wastewater applications. Due to the concentrated nature of wastes from food processing, rendering and some other industrial applications, higher dosages of Odoreze™ then those recommended below may be required to achieve desired process optimization and odor reduction.

    1. Sewers and Lift Stations

    Strong odors from hydrogen sulfide generated from putrefying wastewater or slime coated concrete surfaces can be produced in sewers and lift stations. Depending upon the level of odor, diluted Odoreze™ in the range 1:100 to 1:1000 should be sprayed onto concrete surfaces of lift stations to control odors. In addition, Odoreze™ may also be metered into the lift station and sewage flows at rates of 1-5 ppm to reduce sewage odors. If wet scrubbers using caustic or chlorine are used for lift station air treatment, a 1:200 solution Odoreze™ may be substituted with the scrubber blowdown discharge directly into the sewage flow. Use of Odoreze™ may reduce or eliminate the need for activated carbon in the lift station odor treatment, producing significant savings.

    2. Grit Chambers

    Grit chambers and screens are typically employed at sewage plants to remove very large and heavy grit from sewage flows before pumping to aeration basins. Since these areas accumulate large quantities of garbage, hair, and other odorous materials, they are commonly the source of many odors at these plants. Concentrated or diluted Odoreze™ may be metered directly into grit chambers, sprayed onto screens with automatic spraying equipment, or metered into the sewage plant influent prior to these processes. Typical metering doses are 3 to 5 ppm of stock Odoreze™ effective odor control. Diluted or concentrated Odoreze™ may also be applied to screenings as they are removed and used to deodorize surfaces and equipment on a regular basis.

    3. Aeration Chambers & Ponds

    Most sewage plants in the US utilize stabilization ponds, aerated ponds or aerated activated sludge-type biological secondary treatment plants to digest sewage organics into excess bacterial sludge. Since the processes rely upon efficient aerobic metabolism of the treatment microorganisms, Odoreze™ has been used to increase process microbe activity and reduce odors from aerosol formation. Odoreze™ application may also help to control filamentous organisms, which produce foaming and poor settling. A dosage of 3 to 5 ppm of concentrated Odoreze™ into the sewage flow is effective. Treatment ponds or chambers should first be treated with a one time "shock dose" of 10 to15 ppm concentrate to acclimatize the aerobic biomass to the effects of Odoreze™. Following the shock dose treatment, regular "maintenance doses" of 3 to 5 ppm of concentrate to sewage flow should be added daily to the headworks or directly into the basins or chambers.

    4. Final Clarifiers and Sludge Thickeners

    A dosage of 3 to 5 ppm of Odoreze™ concentrate may be added to the sewage flow in final clarifiers and sludge thickeners, and may also be sprayed in concentrated or diluted form into concrete weirs, metal launders and other components which may harbor sulfide-producing slime growths.

    5. Anaerobic Sludge Digesters

    Odoreze™ can control volatile fatty acid buildup in anaerobic sludge digesters. This increases process stability, reduces odors in sludge discharge, improves methane gas production and reduces or eliminates the need for supplemental caustics, such as lime, which can precipitate in digester tanks. A shock dose of 15 ppm and maintenance doses of 5 to 8 ppm concentrated Odoreze™ is recommended. Aerobic sludge digesters will also benefit from a 3 to 5 ppm daily maintenance program of concentrated Odoreze™.

    6. Sludge Dewatering and Drying

    Sludge dewatering and drying beds or processes typically produce the strongest and most objectionable odors at plants. Odoreze™ may be mixed into sludge prior to dewatering at a 10 ppm dosage to help control odors and a 1:200 diluted solution may be sprayed onto the surface of sludge in drying beds to further reduce odors. Also, a 10 ppm dosage may be applied to the sludge prior to mechanical dewatering via belt press or centrifuge, and equipment may be washed down with a 1:200 solution of Odoreze™ during cleanup procedures. Odoreze™ may be used during land application of sludges by mixing 10 ppm of concentrated Odoreze™ into sludge prior to injection or surface spreading.


    Once mixed with water, the diluted OdorezeTMshould be used within 2-3 days to ensure optimal activity of the product. If you need to store the diluted solution for longer, add 0.15 g sodium benzoate/gallon diluted Odoreze™ or 0.1 oz copper sulphate/gallon diluted Odoreze™ gallons to preserve it.


    Odoreze™ is conveniently available in super concentrated 16 oz. container at a competitive price.  Odoreze™ Wastewater Odor Control Spray is easily diluted to make over 125 gallons saving you money and the environment from packaging and energy waste. The concentrated product is also available in larger sizes upon request.

    Past Question and Answers


    MICHAEL: We are reusing around 500 litres of water in our wash station that has an inbuilt filtration system. The water is relatively clean but has quite a bad door after around 10 or so cycles. Could you please recommend a dosage amount and how often we should be dosing a 500 litre tank? Thanks in advance,

    ANSWER: I would recommend adding 1 litre Odoreze to 500 litres of your wash water. Repeat as often as is required to control the odor. It may take a bit of trial and error to determine the optimal frequency which will depend on the level of odour. But once you determine this, it will just be a matter of repeating it.


    MIKE: I run a fertilizer storage warehouse with liquid fertilizer tanks that smell - anything to help with that stench?

    ANSWER: I would recommend using ODOREZE Natural Wastewater Odor Eliminator to clean and deodorize the tanks. In addition, place SMELLEZE Reusable Chemical Smell Eliminator Pouches in the warehouse and your air ducts to remove and eliminate the fertilizer odors.


    THOMAS: I have a lift pump in my basement to remove toilet, shower and other waste waters from a covered crock. There is awful smell! How or what can I use to kill or eliminate it?

    ANSWER: You can add Odoreze Waste Water Odor Control Additive to your crock to treat the smelly effluent. This will control and eliminate the horrible smelling odors from the waste water.
