1. A control method for a blood treatment equipment, said equipment comprising at least a treatment unit including a semipermeable membrane separating the treatment unit in a first compartment for the circulation of blood and in a second compartment for the circulation a of a treatment liquid and a pump coupled to a passage for the treatment liquid, the method comprising the steps:
Receiving one or more entries of measured information measured during the course of a treatment procedure, Calculating from said measured information an instantaneous clearance KTi, or dialysance value DTi measured at treatment time Ti, an effective total dialysis dosage KTTi, value which has been delivered at the elapsed treatment time TTi, Comparing said calculated effective total dialysis dosage KTTi, value to at least a prescribed reference value for a total dialysis dosage value KTP to be achieved at the end of the treatment, Determining, during treatment, at least one among an estimated remaining treatment procedure time Ttr and an estimated total treatment time Ttot required for achieving said prescribed total dialysis dosage value KTP, Generating an output control signal responsive to said comparison, calculating a desired fluid removal rate UF from said second compartment based on said output control signal, and Automatically controlling the pump to pump the treatment liquid from the second compartment at the desired fluid removal rate UF.
