Abstract: A dosing pump (19) doses antiscalant into a membrane-based water treatment system (1). The dosing pump (19) includes a displacement body for pumping antiscalant into the membrane-based water treatment system (1) in doses. A motor drives the displacement body. A control module controls the motor. The control module is configured to vary the dosage of antiscalant pumped into the water treatment system (1) based on a temperature corrected system variable (SVTc) being based on a plurality of operating variables of the water treatment system (1).

Abstract: A cleaning-in-place method includes terminating a cleaning-in-place cycle if a deviation of a currently detected value of a backwash hydraulic parameter (P) from a value of the same backwash hydraulic parameter (P) detected in a previous backwash cycle (32, 34, 36 38) in the same cleaning-in-place cycle exceeds a predefined deviation limit value. A filter device is provided having a control device for carrying out a respective cleaning-in-place method.

Abstract: A control method uses in a membrane filter system operated in iterative filtration cycles, the cycles including a production period and a following flushing. A setting of a crossflow on the entrance side (4) of a membrane (2) in the production period is controlled such that the energy consumption (E) per filtration cycle reaches an optimum. A corresponding membrane filter system is provided.
