Odor Control

AgriAir purifiers will rid the air of volatile organic substances that may be associated with indoor growing operations. Our line of air purifiers is designed to remove odors and sanitize the air by destroying contaminants at the source, not masking them. Available in a variety of models that are designed to suit any commercial operation. Large or small-scale grow, AgriAir has a purifier designed to meet your garden’s demands.Indoor cultivation always gives the grower the upper hand. In indoor growing, you have the full control of the environment for your plants. Light, water, nutrients, temperature and humidity can all be controlled. However, you also need to control the odor of plants growing indoors.

Odor control for metal casting

Use Ecosorb products to remove foundry smells naturally. Ecosorb odor control products by OMI Industries are extremely effective at breaking down and eliminating the many odorous gases produced by the metalcasting process. They chemically convert foul and potentially harmful gases into non-odorous byproducts. Within the metalcasting industry, Ecosorb products are effective on amines, sulfur dioxide, phenols, formaldehyde, ammonia, partially burnt hydrocarbons solvent odors and more.

Odor control for remediation

Helping others clean up the earth by clearing up brownfield remediation odors. Helping others clean up the earth by clearing up brownfield remediation odors. Brownfield remediation consists of removing large amounts of soil that have been saturated with tar, oil or other contaminating substances. Not only dangerous to handle, the disturbed soil is often infused with very unpleasant and in some cases potentially nauseous odors.

Odor control for rubber and plastic

From process to product, we remove odors from rubber and plastic. Malodors, whether connected to the process or embedded within the end product, are an inherent concern associated with manufacturing polymers. Fortunately, OMI Industries has a versatile solution that’s proven to work within the plastics and rubber industries. Ecosorb odor neutralizing products feature a proprietary, natural and environmentally safe formulation that’s fast acting and effective at removing detrimental polymer odors without the use of masking agents or fragrances.

Odor control for tank cleaning

When it comes to odor management, simply cleaning the tank isn’t enough to remove the odors. Prior to cleaning, storage tanks are vented to the atmosphere in order to reduce the internal gas content to a level below its lower explosion limit (LEL). This permits safe worker access. During venting, odors escape into the atmosphere creating a nuisance to nearby residents, businesses, and employees. Furthermore, storage tank cleaning results in production downtime that reduces plant profitability.

Odor control for refining/petroleum

You refine the fuel, we’ll remove the odors. Oil refineries and petrochemical plants may generate large volumes of odor from the processing and refining of different fuels. Sulfides, mercaptans, and hydrocarbon compounds are all closely related to the oil industry. The odors generated from these industrial compounds are of a high nuisance value and generally create concern among local air boards and the public. Ecosorb odor removal products may be used in a variety of areas around the refinery including water treatment facilities, sludge ponds, sulfur recovery units, and API separators. To remove odors during tank cleaning and maintenance operations, portable dispersion systems can be used in the immediate work area to control malodors. Ecosorb products can be directly injected into flues and stacks and may be used as a substitute scrubbing solution in some applications.

Odor Scrubbers Applications with Hydrogen Peroxide

Hydrogen Peroxide as a Replacement for Sodium Hypochlorite Hydrogen peroxide may be used in both mist scrubbers and packed tower scrubbers as a replacement for sodium hypochlorite (bleach). Like bleach, the process involves two concurrent mechanisms: 1) absorption of the odors (H2S) into the alkaline scrubbing solution; and 2) oxidation of the absorbed sulfide in solution. Step 1: H2S + NaOH → NaSH + H2O Step 2: 4H2O2 + H2S → H2SO4 + 4H2O Typical dose ratios are 5 parts H2O2 per part H2S or, when used in place of bleach, one gallon 50% H2O2 for every 10 gallons of 15% sodium hypochlorite (NaOCl). This generally translates into a break-even cost scenario. Sufficient caustic soda (NaOH) is added to maintain a pH of 10.0 - 10.5 in the scrubbing solution. There is also in practice a process which uses H2O2 in series with bleach to scrub composting odors. This process relies on a series of three packed tower scrubbers: the first is a pH neutral water wash (to remove ammonia and amine odors); the second uses a conventional caustic/bleach solution in which the bleach is purposely overdosed (to oxidize the complex organic sulfur odors); and the third uses a caustic/H2O2 solution (to remove the unreacted chlorine vapors carried over from the second stage). H2O2 + HOCl → HCl + H2O + O2 Typical dose ratios are 0.5 parts H2O2 per part hypochlorite (OCl-), with sufficient caustic soda (NaOH) added to maintain a pH of 8.5 in the scrubbing solution.

Hydrogen sulfide removal in sludge management

In the treatment of sanitary sewage, bio-solids are separated from the liquid. These bio-solids are concentrated and dewatered using filter presses, centrifuges, or other devices. Hydrogen sulfide and mercaptans are released during the dewatering operation. Carus permanganates react quickly and produce immediate results for hydrogen sulfide removal in order to provide a safe, odor free environment and minimize corrosion due to sulfides.

Advanced water treatment equipments for hydrogen sulfide removal

The presence of hydrogen sulfide in home drinking water supplies is not a health hazard, but is a common nuisance contaminant whose distinctive `rotten egg` odor makes water treatment desirable. Several treatment methods are available, and often hydrogen sulfide can be treated and removed using the same process and equipment used for iron and manganese removal.
