Abstract
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.
Claims52
A method for accelerating remediation of at least one pathogens resistant to chlorine in water of an aquatic facility, the method comprising:
- calculating a chlorine dioxide concentration time (Ct) value of the water in real time by a programmable controller;
- activating chemical feed systems by the programmable controller so that the chemical feed systems deliver an acid, an oxidizer and a chlorite ion donor to a conduit connected to the water;
- allowing the acid, the oxidizer and the chlorite ion donor to react in the conduit and form chlorine dioxide;
- and
- supplying the chlorine dioxide from the conduit to the water;
- and
- sustaining a chlorine dioxide concentration in the water until a targeted chlorine dioxide Ct value is reached to achieve remediation of the water, wherein the remediation is at least a 3-log reduction of the at least one pathogen resistant to the chlorine in the water.
A system for controlling accelerated remediation of at least one pathogens resistant to chlorine in water of an aquatic facility, the system comprising:
- at least one sanitizer sensor for measuring a concentration of sanitizer in the water;
- a pH sensor for measuring a pH of the water;
- a temperature sensor for measuring a temperature of the water;
- a chlorine dioxide sensor for measuring a chlorine dioxide concentration in the water;
- chemical feed systems for supplying an acid, an oxidizer and a chlorite ion donor to a conduit in communication with the water;
- a programmable controller in communication with the at least one sanitizer sensor, the pH sensor, the temperature sensor, the chlorine dioxide sensor, and the chemical feed systems;
- the programmable controller is programmed to implement an accelerated remediation cycle by activating the chemical feed systems to achieve localized high concentrations of the acid, the oxidizer and the chlorite ion donor which react to form chlorine dioxide in the conduit that is supplied to the water;
- the programmable controller is programmed to record the chlorine dioxide concentration measured by the chlorine dioxide sensor;
- the programmable controller is programmed to calculate a chlorine dioxide concentration time (Ct) value of the water in real time;
- and
- the programmable controller is programmed to sustain the chlorine dioxide concentration in the water until a targeted chlorine dioxide Ct value is reached to achieve remediation, wherein the remediation is at least a 3-log reduction of the at least one pathogen resistant to the chlorine in the water.
