    Odor Control for Pulp And Paper

    Pulp And Paper Production With None Of The Odor

    Pulp and paper manufacturing is a notorious source of nuisance odors, often stemming from hydrogen sulfide, mercaptans and sulfur dioxide. Fortunately, Ecosorb® products offer a natural and effective solution to neutralize these odors and all others associated with the paper and pulp industry.

    Odor Control for Municipal Waste

    Eliminating Industrial Odors Naturally Is Our Civic Duty

    To handle the odor control needs of municipal and government agencies, OMI Industries has created MUNI® odor neutralizing product. Similar in many ways to its siblings in the Ecosorb® products line, Muni odor control product uses Van Der Waals forces to chemically react with malodor molecules to eliminate odors combined with a natural formulation that makes it safe to work with. What’s more, the Muni® product is surprisingly economical to use. It was specially developed to meet the tight budget limitations faced by municipalities without skimping on industrial odor control effectiveness.

  • 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.

  • Odour removal units for professional kitchen ventilation

    Our company has odour removal units for professional kitchen ventilation, for grills and food preparation areas generally. The operation of the unit is based on chemical or electrostatic filters or a combination of both. The kitchen unit KDSA (with chemical filters) series, neutralizes particles, soot, odors, grease and moisture completely. KDSA units for kitchen ventilation are installed in the cooker hood and are connected with the kitchen areas that produce smoke or where there is smoke and odors such as in kitchen funnels or in washing facilities. The air stream in the deodorizer passes through a set of filters where particles, grease, soot and odors are removed.
