GB/T 30299-2013 General technical specifications for energy recovery devices in reverse osmosis system 1 Scope This standard specifies the classification and model, requirements, test methods, inspection rules, as well as the requirements for marking, packaging, transport and storage of energy recovery devices in reverse osmosis system. This standard is applicable to work exchange energy recovery devices for desalination systems for, such as, seawater desalination and brackish water desalination using reverse osmosis method. 2 Normative references The following referenced documents are indispensable for the application of this document.
