Disclosed herein are methods of producing a gas at a variable rate, the methods comprising dynamically mixing dry particles comprising a precursor and dry particles comprising a proton-generating species to produce a gas and wherein the gas is produced at a rate that is varied by varying the amount of time the dry particles comprising the precursor and the dry particles comprising the proton-generating species are dynamically mixed, the rate at which the dry particles comprising the precursor and the dry particles comprising the proton-generating species are dynamically mixed, or a combination thereof.

The present invention provides a chlorine dioxide manufacturing device that can accurately control the amount of chlorine dioxide produced. The present invention provides a chlorine dioxide gas manufacturing device comprising an electrolysis chamber, a liquid surface level measuring chamber, and a bubbling gas feeding device. The electrolysis chamber and the liquid surface level measuring chamber each comprises an electrolytic solution and a gas, wherein the electrolytic solution comprises an aqueous chlorite solution, and the electrolysis chamber and the liquid surface level measuring chamber are joined to each other above each liquid surface via a gas piping and joined to each other below each liquid surface via an electrolytic solution piping so that the height of the electrolytic solutions contained in each chamber are substantially equal.

Introducing chlorine dioxide solution into an agricultural soil in an amount effective to suspend weed and pathogen growth in the soil. The chlorine dioxide is allowed to decompose in the soil. Then, a crop is planted in the treated soil. The decomposed chlorine dioxide provides nutrients for the crops as they grow.

A chemical disinfection process for vehicles using chlorine dioxide and titanium dioxide with calculated re-treatment formulas and schedules based on bacterial infestation data. Systems and methods that include client devices and servers that monitor and control a chemical disinfection process. The system generates a surety arrangement that facilitates re-treatment and electronic notification alerts to chemical solution vendors, dealers and vehicle owners.

A method and apparatus use conductivity to control the dosing of various chemical additives used in the water treatment industry by modulating the chemical additives within threshold setpoints. Conductivity directly correlates to concentration of chemical additives. This correlation is used to modulate the dosing rates of chemical additives into a process water stream to consistently regulate and balance chemical additive concentration within the process water stream. For example, the method and apparatus dose chlorine dioxide precursor solutions into a process water stream to generate a consistent concentration of aqueous chlorine dioxide.

A scalable, portable and modular chlorine dioxide fumigant decontamination system having an activating area and a neutralizing area which may be housed separately or as a single operationally connected unit, and which may be configured as a closed loop system connected to a decontamination chamber for decontamination of articles, or as an open loop system for decontamination of interiors and large confined spaces, and employing a specialized activating cup that is permeable to air yet substantially impermeable to water and chlorine dioxide reaction by-products such that directing air through the activation cup releases nearly pure chlorine dioxide fumigant. Methods and articles relating to the system are also described.
