 东丽TORAY TMG20-370C反渗透膜更换案例4:食品饮料行业用水TMG20-370C更换案例

某食品饮料生产企业,生产用水处理系统采用东丽TORAY TMG20-370C反渗透膜进行深度处理,处理规模45m³/h,用于去除原水中的可溶性盐类和有机物,确保生产用水质量,系统运行210个月,近期出现产水水质不达标(电导率超标3倍)、运行压力持续升高,经化学清洗后,脱盐率仅能短暂恢复,判断膜元件截留性能已不可逆下降,需更换膜元件。该系统原水为地下水,含有一定量的矿物质和有机物,预处理系统的活性炭过滤器吸附饱和,导致部分有机物进入膜系统,加速了东丽TORAY TMG20-370C反渗透膜的污染。更换前,技术人员更换活性炭滤料,清洗保安过滤器,确保进水水质符合东丽TORAY TMG20-370C反渗透膜的运行要求。更换时,采用专业工具取出旧膜元件,避免损伤膜壳和管路,新的东丽TORAY TMG20-370C反渗透膜安装后,进行密封性测试和性能调试,确保每支膜元件的运行参数一致。更换完成后,系统连续运行2个月,产水电导率稳定在合格范围,运行压力恢复正常,脱盐率稳定在99.6%,东丽TORAY TMG20-370C反渗透膜的适用性和可靠性得到充分验证。
