A system and process may be used to test water samples to measure ATP and/or estimate a microbial population, for example using an adenosine triphosphate (ATP) based assay. The system includes a device that is use in combination with single-use or disposable cartridges. The cartridge receives the water sample and is pre-loaded with one or more reagents. The device receives the cartridge and contains physical, electronic and/or mechatronic devices that interact with cartridge. One or more actions such as metering, mixing and conveying are performed automatically by elements of the device and/or cartridge. A sensor in the device measures light produced in the cartridge from a reaction with ATP in the water sample. Optionally, the cartridge also contains a pre-loaded amount of ATP, which is used to provide an internal reference or calibration measurement.

In some embodiments, a method may include treating pulp in pulp and paper mills. The methods may include providing a peracetate oxidant solution and generating a reactive oxygen species. The peracetate solution may include peracetate anions and a peracid. In some embodiments, the peracetate solution may include a pH from about pH 10 to about pH 12. In some embodiments, the peracetate solution has a molar ratio of peracetate anions to peracid ranging from about 60:1 to about 6000:1. In some embodiments, the peracetate solution has a molar ratio of peracetate to hydrogen peroxide of greater than about 16:1. The peracetate oxidant solution may provide enhanced treatment methods of bleaching, brightening, and delignifying pulp fibers involving the use of peracetate oxidant solutions.

A method and apparatus are provided for dosing biocide into fluid. A biofilm sensor configured to measure an amount of biofilm on the biofilm sensor is used. A method identifies, if present, in a data set representing measurement over time by the biofilm sensor a minimum and an inflection point and, if identified. According to some embodiments, dosing of biocide is determined to be effectuated when an inflection point has been identified occurring time wise after an identified minimum.

A decision support system and method can be used to control a water treatment or distribution system. The decision support system collects data from multiple water system operators and analyses the data for a selected water system according to one or more rules or algorithms. The system returns data, optionally including alerts or predictions, to the system operator. Optionally, the decision support system uses machine learning applied to (i) historical data from a selected water system and/or (ii) data from other water systems to modify the rules or algorithms used to analyze current data from a selected water system. In some embodiments, the data collected includes microbial population data such as ATP data, optionally including derivatives of microbial population data; microbial speciation information; or, metagenomic data.

Disclosed is a humidifier with an electrolytic sterilization module, including a water storage tank and an electrolytic sterilization module arranged in the water storage tank. The electrolytic sterilization module includes a housing arranged in the water storage tank, a titanium anode mesh and a titanium cathode mesh. The titanium anode mesh and the titanium cathode mesh are arranged in the housing. The titanium anode mesh is electrically connected with a positive electrode of a power supply by a titanium anode bolt, and the titanium cathode mesh is electrically connected with a negative electrode of the power supply by a titanium cathode bolt, The titanium anode bolt and the titanium cathode bolt penetrate through the housing and the bottom of the water storage tank.

Systems and methods for delivering silver ion biocide are described herein. The systems described relate to passing water from a water system through a silver ion release module and optional high-concentration silver ion release module.
