东丽TM810C海水淡化膜进水压力
我们在使用海水淡化膜的过程中,通常会注意进水压力这个参数值,为了保障膜元件性能稳定性,我们需要对此有所了解,今天就和大家介绍一下东丽TM810C海水淡化膜进水压力。
东丽TM810C海水淡化膜进水条件
最高操作压力··········································································1200psi (8.3MPa)
最高进水温度···········································································113 ?F(45℃)
最大进水 SDI············································································5
进水自由氯浓度········································································检测不到
连续运行时进水 pH 范围·····························································2-11
化学清洗时进水 pH 范围·····························································1-12
单个膜元件最大压力损失····························································15psi (0.10 MPa)
单个膜组件最大压力损失····························································50psi (0.34 MPa)
进水压力推荐
海水淡化膜:40-45kg/cm^2
低压膜:8-10kg/cm^2
超低压膜:6-8kg/cm^2
高压膜:12-15kg/cm^2
以上参数仅供参考,具体以实际情况为准。
进水压力会影响膜元件的产水通量和脱盐率,透水量随进水压力的提高而增加,由于反渗透膜不可能绝对截留进水中的溶解盐类,因此随着压力的增加总有一定量的透过,因为膜透过水的速率比传递盐类的速率快,这种透盐率的增加得到迅速地克制。所以,应根据各种膜的性能来考虑反渗透进水压力。进水压力的选择还取决于膜的透水性能和水的回收率。
哪有因素会导致进水压力不稳定
一、给水压力过高
1、高压泵出口门调节不当。
2、从高压泵到反渗透器之间的管道堵塞。
3、浓水调节门关闭过紧或堵塞,浓水排放流量小。
4、回收率过低。
二、给水压力过低
1、系统泄漏。
2、高压泵入口水压力不足或泵漏水、漏气。
3、精密过滤器滤芯污堵。
4、高压泵故障。
以上就是东丽TM810C海水淡化膜进水压力的介绍,进水压力不稳定会影响产水水质,因此在日常使用中要及时记录这些参数值,及时发现问题解决。
