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.

The intervertebral disc is avascular. With aging, calcified layers occlude the capillaries at the cartilaginous endplates, reducing diffusion of nutrients and oxygen from capillaries into the avascular disc. Under anaerobic condition, excessive production of lactic acid decreases intradiscal pH and irritates surrounding nerves, causing persistent back pain. Antacid is injected into the painful disc to increase pH and alleviate back pain.
