A sensor is configured to sense a parameter of an aqueous liquid. The sensor has an analog output port configured to provide an analog signal indicative of a sensed parameter, and a calibration memory device storing individual digital information indicative of a calibration of the sensor. A digital output port provides a digital signal indicative of the digital information. A treatment system and method is matched to the sensor.

Implementations of this disclosure are directed to systems, devices and methods for monitoring parameters associated with a body of liquid. In one embodiment, a device includes a container configured to be partially submerged in a liquid and includes sensors disposed within a submerged portion of the container to measure parameters associated with the liquid. An electronic component disposed within an unsubmerged portion of the container transmits information related to the parameters based upon which one or more actions related to treatment of the body of liquid are suggested.

A method and facility for the treatment of brine in salt baths for salting cheese are described. First fractions of dissolved salt are carried along in a cleaned brine permeate and second fractions of dissolved salt are carried along in a contaminated brine retentate. A first quantitative ratio between brine permeate and brine retentate is adjusted in such a manner that the quantity of brine retentate corresponds at least to the quantity of whey and constituents that pass into the brine in the salt bath during the dwell time. The cleaned brine permeate and the cleaned brine are merged in a controlled manner in a second quantitative ratio, by means of which the mixture of both components is concentrated to a salt concentration that corresponds at least to a required salt bath concentration.

A method of automatically ensuring against chloramine contamination in purified product water includes supplying input water to the system and purifying the water to generate the purified product water. The purifying includes removing chlorine and chloramine contamination from the water using a carbon filter and supplying chlorine-depleted water to a deionization filter, and deionizing the chlorine-depleted water using said deionization filter. The product water is supplied to a sensor for continuous monitoring of the resistivity of the purified product water by the first sensor, and an alarm is generated indicating possible chloramine breakthrough when the resistivity of the product water falls below a predetermined resistivity level, which is selected to provide a reserve filter capacity before breakthrough would occur. The carbon filter is replaced at least responsively to the alarm to ensure excess capacity of said carbon filter sufficient to prevent chloramine breakthrough in said product water.

A sprayer apparatus includes a spray nozzle in fluid communication with a reservoir for an aqueous salt solution; at least two electrodes spaced apart from each other integrated into the reservoir; a controller structured to apply electricity to the at least two electrodes, wherein the controller controls an application of electricity to cause a first one of the at least two electrodes to be positively charged and a second one of the at least two electrodes to be negatively charged; and wherein the sprayer apparatus is configured to produce air bubbles during application of electricity, wherein the air bubbles cause agitation and mixing of the aqueous salt solution.

The present invention relates to a method for dosing reagents in water disinfection plants, wherein said method comprises adding said reagents in said plants in amounts defined on the basis of a parameter established a priori as a function of the following parameters: plant volume and/or frequency of use of the plant and/or characteristics of the fresh water introduced therein, said amounts being corrected with a correction factor established following a comparison carried out between the levels of said reagents as actually measured in circulation and reference values.

A method of automatically controlling chloramine concentration in a body of water contained in a reservoir includes: (a) determining residual chloramine concentration in a first water sample obtained from the body of water; (b) automatically engaging a supply of chlorine to add chlorine to the body of water when the residual chloramine concentration in the first water sample is determined to be below a residual chloramine concentration set-point or a first chloramine concentration percentage; (c) determining residual chloramine concentration in a second water sample obtained from the body of water after step (b); and (d) automatically engaging a supply of ammonia and the supply of chlorine to add both ammonia and chlorine to the body of water if the residual chloramine concentration in the second water sample is determined to be below the residual chloramine concentration in the first water sample or a second chloramine concentration percentage.

A mobile device reads a test strip to determine a chemical condition of a liquid or a user inputs a treatment plan into the mobile device. The mobile device transmits the determined chemical condition or the input treatment plan to a liquid treatment system which treats the fluid in response to the determined chemical condition or the input treatment plan.

The present invention is a water purification system and method including a treatment tank with a water inlet, a chlorine source, and a heating element; at least one storage tank with at least one treated water outlet between the treatment tank and the storage tank(s) through which treated water passes therebetween, and a final water outlet(s) through which treated water leaves the system for the benefit of the end user. A power source powers all elements that require power, such as the heating element.
