A method and system for the remediation of the water of an aquatic facility using an integrated process control system to control a mixed halogen-based treatment including chlorine dioxide and a free halogen. The integrated process control system provides versatile control the chlorine dioxide concentration using accelerated side-stream generation of chlorine dioxide. The remediation can occur continuously, and/or intermittently using a daily remediation cycle or a rapid recovery shock.

The invention relates to a method and system for the continuous treatment of the water of an aquatic facility using an integrated process control system to control a mixed halogen-based treatment comprising chlorine dioxide and a free halogen. The integrated process control system provides versatile control the chlorine dioxide and/or free halogen while employing in-situ generation of chlorine dioxide.

A system and method for controlling the accelerated remediation of the water of an aquatic facility using at least one sanitizer sensor, a pH sensor, a temperature sensor and a chlorine dioxide sensor all interfaced with a programmable controller that is programmed to implement an accelerated remediation cycle and configured to calculate a Ct value of the water chemical feed system. The programmable controller activates a chemical feed system to supply an acid, an oxidizer and a chlorite ion donor to a conduit to form chlorine dioxide that is supplied to the water until a desire Ct value is reached.

A method of remediating an aqueous system using the stable aqueous composition.

Stabilized sodium chlorite solution and a method of remediating an aqueous system using the solution

This invention relates to a method for monitoring and controlling the relative concentration of bromide ion used in the cyclic process for enhanced sanitation and oxidation of aqueous systems at aquatic facilities.

Method and composition for use in the cyclic process for the efficient generation of chlorine dioxide in dilute solutions

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.

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.

Biocide and bleach compositions and related methods

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.
