This standard sets minimum requirements for microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), reverse osmosis (RO), electrodialysis (ED), and eletrodialysis reversal (EDR) membrane systems for water and reclaimed water systems. The purpose of the standard is to provide a minimum set of requirements for membrane systems for design, selection, materials, construction, performance, procurement, delivery, installation, and commissioning of membrane systems used for water and reclaimed water treatment systems.
