Synergistic composition and method for odor control
InactiveUS20060006121A1Improve dehydration effectEasy to controlSpecific water treatment objectivesWater/sewage treatment by neutralisationWaste streamVolatile fatty acids
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. The mixture has surprisingly been found to be synergistic with respect to both control of chemical species that produce odors and corrosion of metals commonly found in sludge dewatering equipment.

This invention discloses a stabilized biosolids composition and a method for the stabilization of biosolids. It entails the use of a chemically and biologically reactive material, in the form of ultrafine iron particles. The nanometer-sized iron particles are capable of degrading odorous organosulfur compounds, transforming persistent and toxic organic pollutants such as PCBs and chlorinated pesticides, inhibiting the growth of pathogens by increasing pH and maintaining the increased pH of the stabilized biosolids, immobilizing toxic metal ions such as mercury and lead, and improving the overall quality of biosolids for land application and plant growth.

A washing machine includes a washing tub, a water tub, a drive unit, a feed-water unit, a drain unit, a water softening unit, a pH increasing unit, a pH decreasing unit, and a control unit. The water softening unit is disposed between the feed-water unit and the water tub, and is filled with a weak acid cation exchange material having weak acidic cation exchange groups with a pH from 7.5 to 14 at point of zero charge. The pH increasing unit increases the pH of washing water, and the pH decreasing unit decreases the pH of the washing water. The control unit performs the following operations: controlling the pH increasing unit to increase the pH of the washing water while the washing water is being fed; introducing the washing water with the increased pH to the water softening unit to decrease the hardness of the washing water; introducing the washing water with the decreased hardness to the washing tub; controlling, after the washing water is fed, the pH decreasing unit to decrease the pH of the washing water to a value of 5.5 to 7.0; and introducing the washing water with the decreased pH to the water softening unit.

Method for suppressing microbe activity in meat storage enclosures
InactiveUS7045162B2Enhanced inhibitory effectRaise the pHSeed preservation using chemicalsMilk preservationIncrease phProduct gas
An enclosure treatment method includes introducing a pH increasing material into an enclosure adapted to contain meat products. Introducing the pH increasing material creates a desired pH increasing gas content in the atmosphere within the enclosure. The method also includes the step of maintaining the pH increasing gas content in the enclosure atmosphere while meat products are contained in the enclosure. The pH increasing gas in the enclosure atmosphere is absorbed into water in the enclosure to increase the pH of the water. The water affected in the present treatment process may be moisture collecting on various surfaces within the enclosure, or may be moisture within the meat products being stored in the enclosure. In any event, the increased pH is inhospitable to most microbes and reduces or suppresses microbe activity in the water either by retarding propagation or killing microbes outright.
