Abstract: This invention relates to the use of chlorite-based antimicrobials in a manner where the time of biocidal activity is extended for the microbial control in the water used for drilling, completion and remediation of wells. The invention involves mixing of a compatible extender in the form of sodium chlorate with sodium chlorite to form an antimicrobial formulation. This combination is used with an acid on the site to generate chlorine dioxide which is injected into the water used for hydraulic fracturing or remedial workover. The formulation is a much more effective bactericide for the subterranean oil and gas rich formations. The potency and longevity of biocidal activity is controlled by varying the ratios of chlorate and acid which provide different profiles of the antimicrobial activities.

Abstract: A chemical generator having inlets for receiving multiple reactant and water streams; a dilution chamber; a reaction chamber operably connected to the inlets and to the dilution chamber; an eductor operably receiving the water stream from the one of the inlets and communicating with the reaction chamber for drawing first and second reactant streams into the reaction chamber for mixing. Float control valves interrupt the water stream to the eductor when desired amounts of the first and second reactant streams have entered the reaction chamber, the eductor drawing the activated solution of first and second reactant streams from the reaction chamber into the dilution chamber. The float control valves limit the residence time of the first and second reactants in the reaction chamber and selectively interrupt flow of the water stream into the dilution chamber.

Abstract: Expanded amorphous aluminum silicate (EAAS) is used as a vehicle for a chlorite salt. This vehicle, when exposed to moisture, will release chlorine dioxide (ClO2) for purposes of deodorization or microbial suppression. Thus, where a particular area or volume is to be deodorized or made less microbially contaminated, the EAAS-chlorite salt (most preferably sodium chlorite) is placed in the area or volume to be treated and moisture is permitted to interact with the material. The result of the moisture is to permit the chemical reaction (presumably acidification) of the chlorite salt to yield dioxide gas. While normal EAAS has some inherent acidity, the inherent acidity is low enough so that, even when a chloride salt is encapsulated in the EAAS and the resultant mixture exposed to moisture, ClO2 release is very slow and over an extended period.

Abstract: The present invention is directed to the a composition and method for microbial and odor control. In one embodiment, the method includes mixing amorphous calcium silicate impregnated with a chlorite salt to form a reactant, combining the reactant with an activator to form the composition, and applying the composition to the treatment area. The present invention also includes the preparation of a product usable as a disinfectant and deodorizer, wherein the product includes a mixture of an amorphous and a chlorite salt and wherein the product is packaged as a tablet, permeable sachet, or a permeable patch attachable to a plastic bag. The present invention may also be applied using several methods to reduce the spoilage of produce. The present invention further includes a method for producing chlorine dioxide in accordance with a step-function release profile.

Abstract: The present invention provides a method for the disinfection of beef, pork, poultry and seafood. The inventive method includes the steps of (a) preparing a concentrated aqueous solution of a chlorine dioxide liberating compound having a concentration of from about 0.2% to about 25% by weight of the chlorine dioxide liberating compound and having an amount of an acid sufficient to adjust the pH to from about 1.0 to about 5.0; (b) diluting the concentrated aqueous solution to provide a dilute, acidified solution having a concentration of from about 0.00017% to about 0.17% by weight of the chlorine dioxide liberating compound; and (c)contacting the dilute, acidified solution with beef, pork, poultry and seafood to disinfect the beef, pork, poultry and seafood. Preferably, the chlorine dioxide liberating compound is an alkali metal chlorites, with sodium chlorite and potassium chlorite being particularly preferred.

Abstract: An important and central aspect of the present invention is the use of expanded amorphous aluminum silicate (EAAS) as a vehicle for a chlorite salt. This vehicle, when exposed to moisture, will release chlorine dioxide (ClO.sub.2) for purposes of deodorization or microbial suppression. Thus, where a particular area or volume is to be deodorized or made less microbally contaminated, the EAAS-chlorite salt (most preferably sodium chlorite) is placed in the area or volume to be treated and moisture is permitted to interact with the material. The result of the moisture is to permit the chemical reaction (presumably acidification) of the chlorite salt to yield chlorine dioxide gas. While normal EAAS has some inherent acidity, the inherent acidity is low enough so that, even when a chloride salt is encapsulated in the EAAS and the resultant mixture exposed to moisture, ClO.sub.2 release is very slow and over an extended period. Under most conditions, a more rapid release of ClO.sub.

Abstract: Compositions and processes for the prophylaxis and therapeutic treatment of wounds, chronic non-healing wounds, burns, disease and other dermal disorders are disclosed. The compositions of the present invention comprise aqueous solutions of a metal chlorite having a concentration of from about 0.002% to about 0.5% by weight of metal chlorite. The process of the present invention comprises treating the dermal disorder with an aqueous solution of from about 0.002% to about 0.5% by weight of a metal chlorite. Wounds, chronic non-healing wounds, burns and other dermal disorders treated in this manner heal more quickly and with reduced scar formation. The antiseptic compositions and processes of the present invention exhibit anticollagenous activity such that the characteristics of the healed skin, such as elasticity and tensile strength, are similar to undamaged skin.

Abstract: An automatic lubrication injection sanitization system for sanitizing and lubricating a conveyor chain system is disclosed. The apparatus includes an inlet water line for supplying a flow of water, an inlet sanitizer line for supplying a flow of sanitizer, and an inlet lubricant line for supplying a flow of lubricant. A pump is operatively connected to the inlet sanitizer line and the inlet lubricant line for pumping a proportionate flow of lubricant and sanitizer into the flow of water, forming an outlet mixture flow. An outlet line receives and distributes the outlet mixture flow which is applied to the conveyor chain to sanitize and lubricate the conveyor chain. Preferably, the apparatus also includes two timers which each control a solenoid. One of the timers controls a solenoid in the outlet line, allowing the outlet mixture flow to be selectively cycled ON and OFF. The other timer controls a solenoid in the inlet sanitizer line and allows the inlet flow of sanitizer to be cycled ON and OFF.
