| titleOfInvention | METHOD FOR CONTROLLING OR DETERMINING THE CHARACTERISTICS OF A ULTRAFILTRATION OR MICRO-FILTRATION MEMBRANE |
| abstract | The present invention relates to a method for controlling the characteristics of a microfiltration or ultrafiltration membrane, in particular for the detection of leakage or malfunction of a membrane filtration membrane and, more particularly, a method for determining the In accordance with the invention, at least one batch of a suspension of stabilized magnetic mineral particles, preferably ferric oxide particles of a given concentration, is passed through the membrane. particle size is calibrated to a given size, and at least 60% by volume of said particles have a dimension in the range dpm +/- sigma, dpm representing the mean value of the particle size of said batch and sigma the deviation type, and said size being the particle size value d50 for which 50% by volume of said particles have a smaller dimension or equal to said value d50. |
