Odor can be a problem with anaerobic lagoons. However, in many cases odor can be managed through a variety of methods such as adding sodium nitrate, recirculating pond effluent, and through regular maintenance. An aerobic lagoon utilizes aerators to mix the contents of the system and add oxygen to the wastewater. Wastewater generated from food production and agricultural activities is a major source of environmental pollution. It is also among the most difficult and costly waste to manage because food processing wastewater can contain large quantities of nutrients, organic carbon, nitrogenous organics, inorganics, suspended and dissolved solids, and it has high biochemical and chemical oxygen demands.
Three Approaches To Controlling Odor In Wastewater Treatment Ponds By Joel Bleth, president and CEO, Medora Corporation Due to their ability to circulate a precise horizontal cross-section of water, long-distance circulators can solve odor problems in equalization ponds, anaerobic . A raw sewage odor means lagoon failure: There is not enough DO or circulation to digest influent BOD, so waste just accumulates and digests anaerobically, which is slow and releases foul odors. In addition to being an olfactory nuisance, these sewage odors are often blamed for headaches, eye irritation, and respiratory problems.
DAF is one of the most useful waste treatment processes for several types of food processing wastes, including dairy processing waste. Lagoons and stabilization ponds are often used where conditions allow. Odor from any waste treatment process open to the air is becoming a more serious problem and impediment for using uncovered lagoons. Definitions. Anaerobic: Absence of free oxygen. Effluent: The treated liquid and dilution water from a lagoon, contains important plant nutrients. Freeboard: The distance between the water line and the top of the lagoon’s berm. Lagoon: An earthen structure designed for storage and biological treatment of livestock or poultry water is added to the lagoon to achieve a high degree.

Anaerobic lagoons include minimum design removal efficiencies of BOD, grease, and suspended solids of 80%. The anaerobic process has minimum capital and operating costs, is simple to operate, mechanical equipment is not necessary, and the treatment processes can withstand the shock loadings common in the food processing Size: 1MB.

In addition to a pleasant perfume and essential oils, an odor control product should contain a number of other chemical compounds including: Non-ionic and cationic surfactants to solubilize the perfumes and essential oils in the formulation, and.
For odors generated within the anaerobic layers of sludge, our VitaStim Lagoon Line (above) contains sludge-eating bacteria that remove the excess sludge and eliminate the environment the odors grow in. Low DO Water Column Odors: Odors can also originate as soluble organics and BOD are digested in the water column.
Moreover, conventional digesters are typically used for sludge stabilization in a treatment process, whereas lagoons typically are used to pretreat raw wastewater.
Pretreatment includes separation of settlable solids, digestion of solids, and treatment of the liquid portion.

Bad odors in the food industry vary in type and strength, since they can be created during production, processing, and wastewater treatment. Regardless of the source, odors may be offensive to the public and employees.
Some food processing facilities have their own wastewater treatment plant with lagoons of smelly fats and greases. Many wastewater treatment plants choose to seal the source of odors - whether that’s a tank, basin, or lagoon - with an industrial-grade cover, thereby preventing the diffusion of odor vapors.

Increase Wastewater Circulation—The second step to lagoon wastewater odor control is to ensure that the DO is reaching the very bottom of the lagoon where the odor-causing anaerobic digestion occurs.
By circulating the water column effectively, you can create near homogeneous dissolved oxygen content that will in turn promote odor-free aerobic digestion.

2 these lagoons. Anaerobic lagoons are – m (7 – 15 ft) deep and are anaerobic throughout. 3 These kinds of lagoons are used to treat concentrated wastes, like those that come from a food-4 processing industry. Most anaerobic lagoons are covered with a layer of scum.

There is a long history of use of anaerobic lagoons for treating wastewaters from the processing of cattle and hogs. The most successful of these treatment systems has been designed with low surface-to-volume ratios to conserve heat and to minimize aeration. Depths of 12 to 18 feet have been used.
Covers are required for odor control. Insoluble BOD accumulates on the bottom for anaerobic decomposition of solids while the soluble BOD stays in the water column.
Facultative ponds tend to have a faster rate of sludge buildup, generally ¼” to ½” per service year. Wastewater Lagoon Odor Control and Pond Odor Control. Does your wastewater lagoon or pond stink. Are you wanting to control odors that are offending your campers or neighbors.
Lagoon odor control is a common goal for operators. Fear not, solving and preventing odor problems in lagoon or pond treatment systems is achievable. U npleasant odors at wastewater treatment plants are a reminder that the plant is doing what it is intended to do: treat wastewater. Odors are an unfortunate but completely natural by-product of microorganisms breaking down biodegradable material so that treated effluent can comply with increasingly strict environmental regulations.Aerated lagoons generate lagoon odors when the dissolved oxygen levels in the lagoon are not sufficient to meet the demand of the organic load in the wastewater.
When odors are generated at anaerobic, facultative or aerated wastewater lagoons, odor control can become a challenging, costly and maintenance heavy process.
