<p>In a fluid filtration system with pressurized filtering means making use of filtration additives, a method for automatically controlling one ore more operation parameters of said filtering means, among which at least the dosed amount of said additives, comprising the following steps: before the start of a filtration cycle, establishing a predetermined reference value for the compressibility coefficient (nT) of the deposit that will be formed on said filtering means; during said cycle, periodically recording fluid pressure (P) and flow rate (Q) measurements upstream of said filtering means; after each recording step and on the basis of said measurements, calculating a value of said one or more operation parameters capable of keeping an evaluated compressibility coefficient (n) equal to, or in a neighborhood of, said reference coefficient (nt); and set the calculated value on said filtering means; said steps being iterated for subsequent periods up to the end of a filtration cycle. <IMAGE></p> |
