小区供水纳滤系统更换Nitto海德能ESNA1-LF-LD反渗透膜,解决膜元件污染、产水异味问题。拆卸旧膜前切断水源、电源,泄压至零,拆卸端盖后分类存放密封配件,用专用工具推出老化膜元件,避免膜壳内壁划伤。清理膜壳内壁生物膜、胶体杂质,纯水漂洗至清澈,更换老化O型圈、止推垫。安装Nitto海德能ESNA1-LF-LD新膜时,严格把控方向,浓水密封圈朝向进水端,润滑到位后匀速入壳,对接中心管确保密封。端盖复位后做水压测试,无渗漏方可启动系统。初始运行低压冲洗1.5小时,前24小时产水排放,持续监测水质指标。Nitto海德能ESNA1-LF-LD膜更换后,产水异味消除,除硬、除有机物性能恢复,满足居民饮用水需求。
