Abstract: A method and composition for reducing halogenated decomposition byproducts in the water and air of an aquatic facility. The invention comprises a water soluble metal-porphyrin catalyst that accelerates oxidation of the halogenated decomposition byproducts and their precursors. The catalyst remains stable and only requires replenishment relative to the makeup water added to the treated aquatic facility. The average time interval of replenishment can be measured in weeks or months.
Abstract: The invention relates to a method for the autonomous generation of safe self-limiting concentrations of chlorine dioxide for the treatment of process water. The method comprises a system that is self-limiting such that variations in water flow-rate and/or feed-rate of chlorite donor does not allow for increased concentrations of chlorine dioxide. The effluent concentration from the system does not exceed 3000 ppm thereby providing a means of generating chlorine dioxide for use where remote applications and/or where unskilled personnel are involved.

Abstract: Provided are biocide compositions and bleach compositions comprising organic acyl polyoxychlorine and related methods. The reduction of the acyl polyoxychlorine group releases a reactive intermediate that undergoes a series of cascading reduction steps, resulting in termination products Generally Recognized As Safe.
Abstract: Disclosed is a process for the safe and efficient generation of chlorine dioxide while achieving a variable chlorine dioxide mass flow rate with a turn-down to turn-up ratio of at least 1 to 200. The process allows for a single chlorine dioxide generating system to safely provide variable mass flow rate of chlorine dioxide to applications that have wide ranging chlorine dioxide demand, like those experienced in oil and gas applications.

Abstract: The present invention relates to fracturing fluids of the type used in well bore operations and particularly to a method for producing a gradual reduction in the viscosity of a fracturing fluid through the use of slightly water soluble, organic peroxides incorporated in the viscous fluid. The breaker is effective at controlling the rate of viscosity reduction at low temperature and alkaline pH where other chelated metal catalyst fail.

Abstract: Disclosed is an apparatus and method for the safe and efficient generation of chlorine dioxide. Chlorine dioxide is produced safely and efficiently by diluting a source of chlorite in water to produce less than or equal to 5000 ppm measured as ClO2 while achieving at least 80 wt%, more preferably 90 wt %, and most preferred at least 95 wt % conversion of chlorite anion to chlorine dioxide.

Abstract: A solid composition in the form of a tablet that generates and releases a biocidal solution comprising at least chlorine dioxide with an enhanced weight percent yield is presented. The composition comprises reactants capable of in-situ generation of chlorine dioxide comprising a chlorite donor that is coated with a gel-forming material that slows the rate of dissolution of the high solubility chlorite donor, a free halogen donor, and an acid source, resulting in an unexpectedly high weight percent yield and providing a controlled release of biocidal solution. The compositions of the invention show improved environmental stability which can reduce the cost of packaging and significantly increase the utility of the composition. The controlled release allows the use in multi-tablet chemical dispensers which may otherwise induce potentially explosive conditions or allow rapid release of the biocidal solution thereby inducing a spike in chemical concentration rather than a controlled and sustained release.

Abstract: An efficient cyclic process and related compositions for the in-situ generation of chlorine dioxide from dilute solutions of chlorite anions at near neutral pH. The cyclic process provides a means of safe and effective use of chlorine dioxide with reduced concern of chlorite accumulation in the aqueous system. The disclosed chemistry used to support the cyclic process can be applied independently or in various combinations that are effectively inert. This dramatically reduces safety concerns since the chlorine dioxide is produced in-situ to the application and in dilute concentrations. Also, the process allows for regeneration of inert anions such as bromide and chlorite thereby reducing operating cost.
Abstract: An efficient cyclic process and related compositions for the in-situ generation of oxyhalogens from anions of chloride, bromide and chlorite in an aqueous system using in-situ generated sulfate free radicals. The cyclic process and compositions enhance the rate of inactivation of microbiological organisms especially those resistant to inactivation from free halogen based sanitizers, and oxidation of oxidation resistant organic based compounds in aqueous solution. Aquatic facilities susceptible to accumulation of organic N-chloramines and other oxidation resistant compounds, as well as oxidation resistant parasitic organisms such as cryptosporidium and Giardia, obtain dramatic improvements in the rate of oxidation and subsequent inactivation of these undesirable contaminants.
