The Instruction Sheet on hand is intended to replace Instruction Sheet M 407 G, "Bases for Planning, Ordering and Verification of Warranted Performance for Demineralization Plants with Ion Exchangers", the first and latest edition of which was published in 1986 and which defined the quality characteristics required for demineralized water for the first time. The Instruction Sheet had been created in cooperation with FIGAWA (Federal Association of Gas and Water Engineering Companies) in Cologne and FDBR (Professional Association for Boiler, Pressure Vessel and Piping Technology) in Düsseldorf.
While the previous edition was limited to the issues of ionic exchange for the demineralization of water, the new edition intends to include the application of membrane-based procedures as well as combined procedures, i.e. membrane-based processes complemented by ionic exchange facilities, for producing demineralized water. The information and data shared in this Instruction Sheet are based on the practical experience gained in many existing plants and have been compiled and analyzed by the VGB Technical Committee focusing on "The Chemistry of Water Treatment".
Any liability whatsoever on the part of the publisher, including liability for the accuracy of the data and information presented in this Instruction Sheet, is hereby excluded. Any patent or other property rights possibly affected must be clarified on a case-by-case basis and shall be observed by all parties intending to apply the information presented in this context.
