LANDFILLS

Deodorization of any landfill site will normally be accomplished in one of two ways. The first method is by the use of air contact products. A system of nozzles may be positioned around part or all of the perimeter of the landfill. When complaints are limited to a specific area, or when the prevailing wind direction is predominant, nozzles along a portion of the perimeter may be sufficient for coverage. As an alternative, nozzles may also be attached to the compactors or other working vehicles such that deodorizers are delivered into the air as the odorous material is worked by the equipment. The products may be sprayed continuously or at preset timed intervals such as 20 seconds on, twenty seconds off, etc. The exact interval used will be determined by the intensity of the odor and the number of nozzles (and therefore the quantity of deodorizer) being implemented at any one time. As with any perimeter system, the controller can be designed to divide the nozzles into connected zones such that groups of nozzles may be turned on or off independently.

A second method of treating landfills involves surface contact products. These products may be sprayed directly on the working face or faces of the landfill. This is usually accomplished by means of a fire nozzle attached to a water cannon. The water truck simply drives along the edge of the area to be treated, while the cannon and nozzle deliver the deodorizer to the surface. A fan sprayer may also be attached to the outlet on a water truck. Some nozzles can easily reach 100 feet (33 meters) or more from the truck. This type of application will ideally occur in the morning as work begins, and in the evening as work concludes. In situations where tarps or any permeable alternative daily cover is used, the topical deodorizer may be sprayed on to the alternative daily cover for overnight deodorization. The topical products will normally contain odors until the treated surface is agitated.

An excellent method of complete odor management includes both technologies. During the active hours air contact products may be implemented from a stationary perimeter system or from equipment mounted nozzles as needed. Overnight, the surface treatment maintains odor control allowing the air contact product to be turned off.

COMPOST SITES

Odor management at compost sites may be accomplished using any one or a combination of air contact, surface contact, and incorporation products. The determination of which odor control method to use is normally based on the types of materials being composted, the composting method or technology being used, the site layout and topography, and the process activity generating the majority of odors. When air contact is the chosen method, a perimeter nozzle system or nozzles attached directly to row turning equipment or front end loaders is implemented as with landfills. This may be especially effective if the majority of problems and complaints occur when the composting material is turned. If problems occur during screening or mixing or any other specific activity, nozzles may be attached directly to the equipment involved or to infeed and discharge conveyors supporting the equipment.

Many site operators prefer a more direct approach on an "as-needed" basis. Surface contact products are an ideal choice in these situations. With proper nozzles, surface treatment may be applied directly from the row turner to the composting material as it is being turned. Treatment of leachate and standing water may be accomplished with surface contact as well. Any kind of spraying equipment is suitable for deodorizing trucks and unloading areas with surface contact. Surface contact may also be utilized in situations where difficult topography makes perimeter treatment impractical or ineffective. Pressure sprayers, water cannons, and even hand-held sprayers are often implemented.

Incorporation treatment is utilized in limited rowturn static pile or aerated static pile operations. While management has the option to treat the piles topically after formation, it is usually more beneficial to incorporate a single treatment product into the mix as the pile is being formed. This may be accomplished easily if the various component feedstocks are blended in a batch mixer. The treatment product is simply added into each batch in the correct dosage. At sites where loaders or turners accomplish mixing, nozzles may be attached directly to the equipment in the proper size and capacity to administer the product. In these situations and any time the spray apparatus is attached to moving equipment, a separate tank, pump, and power source are also attached.

Indoor composting operations are often plagued by odor problems just as outdoor sites are. Any of the three methods may be adapted to indoor use. In buildings which have fixed exhaust points or where air is collected and run through biofilters, specific methodologies should be employed. Air contact products may be atomized into the exhaust stacks or ports to treat odorous air as it leaves the location. Biofilters may be sprayed topically for surface control, or incorporation products may be added to improve efficiency and longevity of the filter media.

In-vessel composting systems may employ incorporation treatment during the curing phase of the process. The treatment is applied by means of nozzles at the discharge conveyor from the vessel. Surface treatment is also an option for these sites during the curing period.

WASTE TRANSFER STATIONS

Many communities forward their trash to a center where it is more efficiently loaded and transported to a regional disposal facility. These centers are called transfer stations. In many cases waste materials remain in these stations for brief periods as they are reloaded and forwarded for disposal. However, sometimes situations occur which require waste to remain over longer periods of time. Even when the waste is quickly removed, thin films of liquid and biological material are left behind, covering the floors and even walls in some cases. These films quickly develop odors.

Housekeeping often reduces these odors, but much of the film is resistant to normal soaps and detergents. Cleaning with our saponifying product "GOC" will help to remove much of the vegetable and animal fats and grease that is contained in the film. GOC is applied just as any floor cleaner would be. Because it converts non-petroleum fats, oils, and grease into soap, no additional detergent additives are needed.

For conventional odor treatment, many transfer stations use pressure spray equipment to administer surface contact products to the floors, walls, trucks, and standing wastes. This is an excellent technique between cleanings. Overhead air contact atomizing systems are probably the most common systems found in transfer stations. A matrix of nozzles is suspended from the ceiling of the building. Ideally, the nozzles are positioned high enough and are atomizing the particles fine enough to avoid conditions of excessive moisture below. Nozzles may also be positioned around the truck access doors. These are especially effective in warm weather when truck doors remain open throughout operating hours.

POULTRY BREEDING (CONFINEMENT) BARNS

One of the major problems in broiler and turkey production is controlling ammonia levels in the confinement shed or barn. Thousands of birds eat, sleep, and grow in these buildings. Since the birds' waste products remain in the building in most broiler and turkey operations, ammonia levels escalate to the point of impacting growth and mortality rates among the birds - especially in colder weather when doors and windows must remain closed. Ammonia levels increase succeptibility to respiratory and digestive tissue damage, and impair the bird's ability to metabolize its food.

Surface contact products are the most efficient method of limiting ammonia formation in these facilities. Using pressurized mobile spraying equipment, or overhead nozzle systems (which are often installed for humidification purposes), surface product may be applied to the area efficiently and quickly. These are completely safe, cost effective, and long lasting liquid products. Due to the sensitive respiratory systems of the birds, air contact products are not an option. Since the birds generally agitate the barn litter, the surface application is quickly mixed throughout the loose material. Due to the mixing action of the birds, the surface product assumes the properties of an incorporation product, increasing longevity of performance.

FEEDLOTS

Feedlots present the same odor treatment options as landfills: either perimeter atomization or surface treatments are generally viable. Surface treatment may have advantages in that, similar to poultry sheds, the mixing action of cattle hooves will quickly turn the surface treatment into an incorporation treatment. Decreasing the actual formation of odorous gases may have more beneficial value to the animals than treating the already formed odors with air contact reactants as the gases leave the site.

Nevertheless, atomization systems remain viable options. Since surrounding acreage may be considerable, it is unlikely that actual perimeters of the site will be a reasonable choice unless power and water are available near a particularly sensitive road or property line. In most situations, nozzles installed nearer to or on the barn or extended from fences are more feasible.

Surface treatment may be labor and time intensive due to the size and level of activity at many feedlots. A small vehicle with mounted motorized sprayer is ideal. Also similar to landfill operations, a water truck with cannon and fire nozzles may be used. Surface treatment has an advantage in that no system of nozzles, tubing, and controls need to be installed. One disadvantage to surface treatment is its lack of public visibility. An atomization system may be visible to the public, creating a positive perception of the operation and its intent to manage odors. Surface treatment activity will be witnessed by few. The evidence of its occurrence will be the diminished odors at the site.

LAGOONS

Lagoons, whether wastewater, manure, or leachate, are almost always treated by the use of incorporation agents. The product selected may be needed to improve conditions for microbial proliferation, to increase solids decomposition rates, or to utilize excess sulfur or nitrogen being expelled as odorous gas. Usually, because the three problems tend to be part of the same problem, the product incorporated must deal with all three issues.

Methodology of treatment of lagoons varies with circumstance. Lagoons which do not receive daily inflow may be treatable manually, simply by pouring in the correct dosage initially, and by adding corresponding doses as new inflow occurs. Lagoons which do receive daily or regular amounts will install a product reservoir and a metering pump at the source of the inflow, or somewhere along the route to the lagoon.

The initial dosage for an existing lagoon will vary depending on the product selected. Application of this initial dosage is ideally accomplished as follows: A number of locations around the exterior of the lagoon should be selected. The correct portion of the total dose should then be incorporated at each location. For maximum benefit, pumped injection (by flexible pipe) of the product into the solids beneath the lagoon surface is highly recommended. The faster the product reaches its target area, the faster bacteria will be nourished and subsequently proliferate. Increased proliferation will result in faster degradation of the solids and digestion of the material with substantial reductions in the formation of odorous gases.
