Despite appearing at relatively low concentrations, weak acids of various types have a significant impact on the design, operation and the quality of the product water in many RO (reverse osmosis) applications. During the RO process, weak acid species are simultaneously involved in interconnected tra

Blending desalinated water with surface and/or ground water may result in water that has a negative precipitation potential with respect to CaCO3(s), rendering it chemically unstable. In this paper a simulation tool for calculating the pH and calcium carbonate precipitation potential (CCPP) values a

In 2010 desalinated water is expected to provide approximately 25% of Israel’s fresh water supply. Since desalination is cost-effective only if operated constantly, areas adjacent to the desalination plants may receive unblended desalinated water for prolonged times while other sources are added onl
