Abstract
The invention relates to a method of diagnosing the operation of a water purification installation of the filter medium device type, the material of the filter medium being made up of particles, the method including the following steps: a characterization step of characterizing at least one physical and/or mechanical parameter of the filter medium device to establish a permeability value Ks (expressed in m/s); a comparison step of comparing said established permeability value Ks with a predetermined range [k; k] of permeability values representing a satisfactory operating state of the purification installation; and a diagnosis step during which the filter medium device is assigned an operation indicator according to the result of the comparison step. Applications include non-collective sanitation (NCS) systems and stand-alone sanitation systems.
