Abstract

The present disclosure describes a dosing pump (19) for dosing antiscalant into a membrane-based water treatment system (1), wherein the dosing pump (19) comprises - a displacement body for pumping antiscalant into a membrane-based water treatment system (1) in a dosed manner, - a motor for driving the displacement body, and - a control module for controlling the motor, wherein 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). The present disclosure also describes a method for dosing antiscalant into a membrane-based water treatment system (1), the method comprising the steps of: - determining a temperature corrected system variable (SVTc) based on a plurality of operating variables of the water treatment system (1), - varying the dosage of antiscalant fed into the water treatment system (1) based on the temperature corrected system variable (SVTc).
