摘要： A method for preparing an aqueous solution of a defined pH comprising an acid, a base and optionally one or more additives is provided. The method comprises the steps of:
a) calculating the theoretical concentrations of acid and base for the solution to have the defined pH using the Henderson-Hasselbach equation in combination with the Debye Huckel theory for a range of different additive concentrations; b) preparing a sample of the buffer for the range of additive concentrations and measuring the actual pH for each additive concentration; c) calculating a value for delta pH, ΔpH, being the difference between the theoretical pH and the actual pH, for each additive concentration; d) generating a mathematical model describing the relationship of ΔpH with additive concentration; e) selecting the defined pH and additive concentrations; f) using the mathematical model generated in step d) to calculate ΔpH for the defined pH and additive concentration; g) calculating a ΔpH-corrected pH by summing the defined pH and delta pH; h) using the ΔpH-corrected pH to calculate the concentrations of acid and base using the Henderson-Hasselbach equation in combination with the Debye Huckel theory; i) preparing the solution using the concentrations calculated in step h).-

摘要： The invention relates to a method for maintaining an equilibrium of a physico-chemical parameter of a medium, and for recovering the equilibrium in case of loss of the latter. More precisely the method makes it possible to estimate the relevance of a corrective action on the medium in order to recover an equilibrium. The method is implemented by the processing unit of a system for regulating the medium. The invention applies in a non-limiting manner to the regulation of the equilibrium of the bathing water of a swimming pool.

摘要： A method for controlling the saturation level of gas in a liquid discharge includes obtaining temperature and pressure measurements of a solvent in a mixing vessel and obtaining a pressure measurement of a source feedstock in a feedstock tank, correlating the temperature and pressure measurements of the solvent to baseline data to generate a theoretical uptake rate for the source feedstock into the solvent and a theoretical flow rate of the source feedstock into the mixing vessel, and determining a required opening setting for a feedstock valve in the feedstock input line in order to achieve a desired liquid displacement in the mixing vessel. The method includes determining an uptake duration and achieving an uptake displacement equivalent to the reverse of the desired liquid displacement. The method includes generating a valve operating control law for how the feedstock valve should function in a cycle.

摘要： A monitoring assembly includes a diverter, a fluid delivery network, an analysis subsystem, and a pump. The diverter be configured to fluidly couple to a single port of a process pipe. The network can be configured to receive a process fluid including an incumbent additive from the diverter. The analysis subsystem can be configured to receive the process fluid from the network, to measure a predetermined property of the received process fluid within a sensing chamber, and to output a signal representing the measured property. The pump can be configured to urge the process fluid from the analysis subsystem to the diverter via the network. The assembly can also include a conditioning subsystem configured to treat the process fluid with a process additive prior to measurement. The assembly can further include a filtration subsystem configured to filter the process fluid prior to measurement.
