Container treatment plant for treating containers, such as bottles, in the beverage processing industry comprising a chlorine dioxide producer, a chlorine dioxide consumer, comprising at least one container treatment machine, in particular a pasteurizer, such as a tunnel pasteurizer, and a metering device that can introduce a solution containing chlorine dioxide produced in the chlorine dioxide producer into the chlorine dioxide consumer, where the chlorine dioxide producer is configured to produce chlorine dioxide through a reaction of sodium chlorite and sulfuric acid.

Methodologies, systems, and devices are disclosed for generating a chemical compound. A reaction chamber holds an amount of a precursor chemical, an activator chamber holds an amount of an activator chemical, and a quenching and neutralizer chamber holds an amount of quenching and neutralizing chemicals. A pump transfers the activator chemical from the activator chamber to the reaction chamber, where the activator chemical reacts with the precursor chemical to form the desired chemical compound. The desired chemical compound is allowed to exit the reaction chamber. Subsequently, the pump transfers the quenching and neutralizing chemicals from the quenching and neutralizer chamber to the reaction chamber, resulting in a quenched and neutralized solution.

Chlorine dioxide compositions and methods of using the chlorine dioxide compositions on animal skin are disclosed. The chlorine dioxide compositions are formed by mixing an acidic composition and a chlorite salt composition together. The acidic composition includes an acid and an aldehyde.

Aqueous solutions of hydrogen peroxide and alkali metal chlorate are stabilized by a polymeric stabilizer selected from phosphino polycarboxylic acid, poly(acrylic acid), a poly(acrylic acid)-acrylamidoalkylpropane sulfonic acid co-polymer and a poly(acrylic acid)-acrylamidoalkylpropane sulfonic acid-sulfonated styrene terpolymer.

Chlorous acid is generated from a chlorite salt precursor, a chlorate salt precursor, or a combination of both by ion exchange. The ion exchange material facilitates the generation of chlorous acid by simultaneously removing unwanted cations from solution and adding hydrogen ion to solution. Chlorine dioxide is generated in a controlled manner from chlorous acid by catalysis. Chlorine dioxide can be generated either subsequent to the generation of chlorous acid or simultaneously with the generation of chlorous acid. For catalysis of chlorous acid to chlorine dioxide, the chlorous acid may be generated by ion exchange or in a conventional manner. Ion exchange materials are also used to purify the chlorous acid and chlorine dioxide solutions, without causing degradation of said solutions, to exchange undesirable ions in the chlorous acid and chlorine dioxide solutions with desirable ions, such as stabilizing ions, and to adjust the pH of chlorous acid and chlorine dioxide solutions.

The present invention relates to a process for producing an aqueous solution containing chlorine dioxide from gaseous chlorine dioxide and from an aqueous phase. The invention additionally relates to an apparatus for producing an aqueous solution containing chlorine dioxide and/or for carrying out the process of the invention. Finally, the invention also relates to the use of an apparatus according to the invention for carrying out a process according to the invention. In the following, all statements made in respect of the process of the invention also apply correspondingly to the apparatus of the invention and the use according to the invention, and vice versa, unless indicated otherwise in the individual case.

In order to provide a method with which the costs incurred in conventional methods for producing chlorine dioxide according to the chlorite-acid method can be significantly lowered, a method is proposed according to the invention, in which an acid, a chlorite and optionally water are introduced into a reactor, wherein in the method the reaction temperature in the reactor is determined and the quantity of acid, chlorite and/or water which is/are introduced into the reactor is chosen such that the acid introduced into the reactor is introduced into the reactor with a molar excess relative to the chlorite introduced into the reactor, wherein the level of the molar excess is varied with the level of the reaction temperature determined. In addition, the present invention relates to a device which is suitable for implementing the method according to the invention.

The present invention relates to a method of generating chlorine dioxide from chlorite salts in the presence of an iron ion-containing complex, a method of treating a substrate with a chlorine-containing oxidant in the presence of an iron ion-containing complex and related aqueous media, kits and compositions.

The present invention provides a safe, disposable and biodegradable chlorine dioxide micro generator that uses water soluble paper and hydrogel or compressed cellulose encased in filter paper pouch. The chemicals are kept in a stabilize form until activated by the addition of water. Multiple levels of protection against early exposure to water such as a foil pouch and an impermeable outer container allow for the safe transportation and storage in small, ready for deployment amounts of the chemicals. Water permeated the chemical pack housing and dissolves the paper walls of the chemical pouch housing and then the water facilitates the reaction between the acid and the sodium chlorite to form chlorine dioxide gas as will be described further hereunder. Absorbent and permeable materials packaged around the chemicals provide for the safe containment of the chlorine dioxide solution, and the expeditious aeration and release of the chlorine dioxide gas, once the chemical reaction has been completed.

A disinfectant device including a pouch, the pouch including a first layer of material coupled to a second layer of material and defining a compartment therebetween. At least one dry reactant is retained within the compartment, the at least one dry reactant producing chlorine dioxide gas when exposed to water. A wick is at least partially disposed within the compartment. At least one from the group consisting of the first layer of material and the second layer of material define an array of ports along a periphery of the pouch and an array of fluid conduits, the array of fluid conduits being proximal to the array of ports, offset from the array of ports, in fluid communication with the wick, the compartment, and the array of ports.
