A method for operating a water treatment plant, wherein the plant is equipped with an apparatus for injecting a gas containing oxygen into an effluent, the method comprising a phase of detecting anomalies in the operation of the apparatus, wherein the phase of detecting anomalies comprises an implementation of the following steps: providing data representative of the operating state of the apparatus; and providing a system for acquiring and processing said data.

Method for detecting anomalies in a water treatment plant using an apparatus for injecting oxygen into a waste pool

Method for filling a tank with pressurized gas to a target pressure from at least one pressurized gas source via a transfer pipe provided with at least one valve, the tank having a predetermined inner length and predetermined inner diameter, the end of the transfer pipe forming an injector with a predetermined injection diameter; said method comprises a step for transferring pressurized gas from the source to the tank at a predetermined flow rate, the method comprising a step of controlling the transfer of gas from the source to the tank to reduce the heat produced in the tank, the step of controlling the transfer of gas comprising at least one of: sizing of the injection diameter, and sizing of the flow rate of the transferred gas; the control step being carried out according to the ratio L/D between the length and the diameter of the tank.

Method and device for filling a tank with pressurized gas

A method for filling or withdrawing from a pressurized gas tank. The tank having a wall having a cylindrical overall shape with dimensions and thermophysical properties that are given and known. The method including the regulation of the flow rate of the introduced or withdrawn gas, and/or of the temperature of the introduced gas, to avoid a situation in which the tank reaches a given high temperature threshold or a given low temperature threshold. The method including a step of estimating, by calculating in real time, at least one tank temperature from: the average temperature of the tank wall, the maximum temperature reached by the tank wall, the minimum temperature reached by the tank wall, and in that the flowrate of gas or the temperature of the gas is regulated depending on the calculated tank temperature.
