The process for optimized control of a filtration membrane unit, comprises injecting a dose of coagulant reagent of 30-80 times lower than an annulant dose of Zeta potential of effluent in an upstream of the membrane (6), measuring a temperature of the effluent, measuring a flow of filtration, and measuring a transmembrane pressure (9). The permeability of the membrane is corrected to a reference temperature of 20-25[deg] C. The injection of the coagulant reagent is controlled when a permeability of the membrane becomes lower than a threshold value of 10-40% of an initial permeability.

The permeability of the membrane is corrected to a reference temperature of 20-25[deg] C. The injection of the coagulant reagent is controlled when a permeability of the membrane becomes lower than a threshold value of 10-40% of an initial permeability, and actuated when the membrane permeability becomes equal or higher than a stable LpO value before reduction during determined maintenance of 12 hours. Time for evolution of permeability is 10-60 min. An independent claim is included for an installation for optimized control of a filtration membrane unit. |
