Abstract
A method is disclosed for scaling control in a membrane system operation. The method can be performed by a model in the control system of a plant. The method can include selecting one or more antiscalants corresponding to one or more components of the scale, based on one or more of feed water condition, membrane material, membrane fouling status and a kinetic study relating to a reaction between the antiscalants and the components of the scale. The composition of one or more selected antiscalants can be estimated based on an overall scaling rate constant.
