  陶氏纳滤膜NF90-400/34i系统应用特点

  一、系统采用了目前国际上技术最为先进的陶氏膜公司的膜元件,截留精度有所保障,同时膜的通量及系统整体运行的稳定性能更加可靠。

  二、该系统在较低的操作压力下即可运行,从而完成物料的脱盐与浓缩分离,脱盐率非常高,产水水质标准高,且稳定性好。

  三、可根据客户具体要求回收透过液,且膜元件的性能可通过清洗进行恢复,从而降低系统运行成本。

  四、系统在常温状态下即可运行,且不会发生相变,不会对物料中的有效成分造成任何不良影响,因而特别适合用于热敏性物质的处理,产出物的有效成分含量高。

  五、系统运行过程采用的是全封闭管道式,管道材质全部都是卫生级不锈钢,工作现场安全卫生,可满足GMP或FDA规范化生产要求。

  六、系统运行所需能耗低。

  The DOW FILMTEC NF90-400/34i nanofiltration element is a high area, high productivity element designed to remove a high percentage of salts, nitrates, iron, and organic compounds such as pesticides, herbicides, and THM precursors. The high active membrane area combined with the low net driving pressure of the membrane allows the removal of these compounds at low operating pressures. It uses a 34 mil feed spacer to lessen the impact of fouling on pressure drop across a vessel and enhance cleaning effectiveness. The iLEC™ interlocking end caps reduce system operating costs and the risk of o-ring leaks that can cause poor water quality.

  Used In:

  Production of drinking water

  Water reuse

  Industrial water demineralization

  Advantages:

  Low energy usage reduces power consumption and costs

  Durable with good cleanability for long element life

  Thicker feed spacer delivers better tolerance of suspended solids and enables more efficient cleaning of organic material from the element

  FilmTec Performance and quality
