Minimizing the Use of Chemicals to Control Scaling in Sea Water Reverse Osmosis: Improved Prediction of the Scaling Potential of Calcium Carbonate：UNESCO-IHE PhD Thesis

In this his doctoral dissertation in water education at the Delft University of Technology in the Netherlands, Waly describes approaches and specific techniques for reducing the use of chemicals to control scaling by calcium carbonate in pipes and other components of systems that use the reverse-osmosis process to transform sea water into fresh water. The core of his approach is a more accurate prediction of the degree of scaling, so that no more chemicals than necessary can be used. A native of Cairo, he is vitally aware of the problem.
