Improper startup procedures\u2014such as sudden pressure surges, incorrect flushing, or unstable pretreatment\u2014can lead to irreversible membrane damage, costly downtime, and early performance decline. Whether you’re commissioning a new system or restarting an existing line after downtime, understanding the correct protocol is essential.<\/p>\n

Before applying pressure to an RO system, it\u2019s essential to verify that the pretreatment processes are fully operational and delivering water within the membrane manufacturer\u2019s specifications. This includes stable feed pressure, correct pH range, low turbidity, and a consistently low Silt Density Index (SDI).<\/p>\n
