保护离子交换树脂---ICI Zeneca UK 项目历史 这家工厂为ICI集团生产特种化学品，他们的锅炉需要每小时140吨的软化水，他们使用一个网式过滤器保护离子交换树脂床，但发现离子交换树脂床需要4-5天既需反洗一次，在有些情况下他们被迫将树脂全部拿出进行再生。? 解决方案 ARKAL公司进行了仔细的实验，Zeneca 实验室进行了检测，根据他们的要求，安装了ARKAL公司 一台 8 x 3” SPIN KLIN 过滤系统，精度为75 微米，有效的将离子交换树脂床的反冲洗时间延长到4-5周 ?

Water is processed through the Pre-filter skid, stored in a transfer tank, processed through the RO skid, and is stored in holding tanks for use at the demineralizers. Process water passes through the following major components: Lake water supply pump (P-8) with back pressure control valve (75 psi) Disk Filters (50-micron filtration) with back pressure control valve (65 psi) Ultraviolet Disinfection System (UV-1) Variable Speed Drive Pressure Control Pump (P-1) with recirculation loop Ultra-filtration (UF) System (0.200-micron filtration) with back pressure co
