Ecolo Odor Control Systems Worldwide

odouriferous organic compounds found in trees, grasses and flowers. AirSolution works as a neutralization process to degrade and destroy the odour causing molecule, which in this case is hydrogen sulfide.

The elimination of odour using airSolution is a result of an oxidation-reduction reaction. In the oxidation-reduction reaction one of the reactants is reduced (gains one of more electrons) and another is oxidized (loses one or more electrons). Because terpenes, constituents of essential oils, are highly reactive, simply exposing any gaseous stream to them will initiate a chemical reaction so long as three conditions are met. First the molecules must collide. This is accomplished by atomizing airSolution into the air over the affected area, in this case the wastewater lagoons. Second the colliding molecules must be positioned for transition. This is accomplished by atomization to the proper size to establish and maintain exposure and contact. Thirdly the collision must have the required energy, through velocity, to form the transition state.

ECOLO’s odour control systems and specially formulated airSolutions are engineered to satisfy these condition. In addition, it must be stated that airSolution is a complex blend of many active ingredients that make it impossible to write chemical equations which would represent all the chemical reactions. Aside from that, the wastewater lagoons at Ault Foods happens to be one of the more interesting types of reactions, involving the formation of a hydroxyl radical (OH). This radical is just as reactive as the terpenes, and is made available for the oxidation reaction. Amino-Hydroxyl groups in collision with sulfides, oxidize the sulfides into amino hydroxyl sulfates and then into easily degradavle sulfate ions. In this process the amino hydroxyl radical is reformed and continues reacting with the next sulfide molecule it encounters. This is the oxidation-reduction reaction that is used to degrade and eliminate the hydrogen sulfide odours in the Ault wastewater lagoons.

The system that was installed at the lagoons to facilitate such a reaction includes the ECOLO Pump Spray System- 150 (EPSS-150), with 100 spray nozzles. The nozzles were mounted on posts (10) feet in height, positioned around the perimeter of the two lagoons approximately twenty (20) feet apart. An automated mixing system was installed for ease of operation. This mixing system combines the correct concentrations of water to the custom designed airSolution formulation. Atomization times and durations were set, running twenty-four (24) hours a day, atomizing precisely measured dose of
