Abstract: A synergistic composition is provided for controlling odor from waste products. The composition comprises a combination of nitrate salt, sulfide-consuming compound, pH-elevating compound, sulfide-oxidizing, nitrate-reducing bacteria, and sulfide-oxidizing enzyme. The method includes adding a sufficient amount of the composition to a waste stream to provide sufficient sulfide-consuming compound to effect immediate removal of sulfide. The composition incorporates a pH elevating compound, which both decreases the amount of gaseous H2S and puts the aqueous phase into a pH range where naturally occurring bacteria can more easily metabolize the sulfide. The composition also includes one or more nitrate salts which will accomplish longer term prevention of odors. Specific bacteria are incorporated into the formulation to insure that the nitrate has the right type and amount of bacteria present to prevent formation of and/or consume sulfide.

Abstract: A synergistic composition and method is provided for controlling odor from waste products. The composition comprises a combination of magnesium hydroxide and a sulfide-consuming compound. The method includes adding a sufficient amount of the composition to a waste stream to provide sufficient sulfide-consuming compound to effect immediate removal of sulfide. The composition incorporates a pH elevating and buffering compound, which both increases and buffers the pH. The increased pH serves to reduce both the volatile sulfide species and the volatile fatty acid (VFAs) species. The elevated pH also promotes the growth of naturally occurring bacteria which metabolize the sulfide to an innocuous form. Finally, addition of the composition drives the pH into a range where the growth of sulfide producing bacteria is inhibited.

Abstract: The invention is directed to a process for removing chlorite ion from a body of water containing unacceptably high levels of chlorite comprising adding to said body of water a chlorite removal chemical selected from the group comprising sodium dichloroisocyanurate dihydrate, sodium dichloroisocyanurate, trichloroisocyanurate, polyaluminum chloride, sodium permanganate, potassium permanganate, and catalase enzyme.

Abstract: A vehicle having a tire fire suppression system includes a vehicle body for transportation of occupants or cargo. A plurality of combustible tires is connected to the body. The tires are susceptible to auto-ignition in response to exposure to an elevated temperature condition. The fire suppression system is connected to the body and includes a container of a fire suppressant. At least one temperature sensor is positioned in close proximity to at least one of the tires. The temperature sensor is adapted to be activated in response to the elevated temperature condition and before the auto-ignition. At least one nozzle is positioned to direct the suppressant toward the tire. An actuator connects the container to the nozzle for the suppressant to be dispersed from the nozzle in response to activation of the sensor.

Abstract: Disclosed is a method for preventing osmotic membrane fouling comprising treating reverse osmotic feed water and membranes with chlorine dioxide at an extremely low concentration, e.g., as low as one part per billion in the feed water. The effective range may be in the range of 1-900 parts per billion. Also disclosed is a membrane separation system in which fouling is prevented using ultraviolet, pH acid adjustment or an electrochemical generator to produce the chlorine dioxide.
