📖 Terms & Definitions / 术语和定义 ai_extracted
- 反渗透膜reverse
- osmosis membrane 用特定的高分子材料制成的,具有选择性半透性能的薄膜。它能够在外加压力作用下,使水溶液中 的水和某些组分选择性透过,从而达到纯化或浓缩、分离的目的。
- 反渗透膜元件
- reverse osmosis membrane element 用符合标准要求的反渗透膜构成的基本使用单元。
- 反渗透膜组件
- reverse osmosis membrane module 按一定技术要求将反渗透膜元件与外壳等其他部件组装在一起的组合构件。
- 反渗透
- reverse osmosi s 在膜的原水一侧施加比溶液渗透压高的外界压力,只允许溶液中水和某些组分选择性透过,其他物 质不能透过而被截留在膜表面的过程。
- 脱盐率salt
- rejection 表明设备除盐效率的数值。 GB/T 19249-2003
- 原水回收率
- recovery 设备对原水利用效率的数值。
- 渗透水permeat
- 经设备处理后所得的含盐量较低的水。
- 浓缩水
- concentrate 经设备处理后的含盐量被浓缩的水。
- 保安过滤器cartridge
- filter 由过滤精度小于或等于5 I. m的微滤滤芯构成的过滤器,装在反渗透膜前,以确保进人反渗透膜的 进水水质满足规定的要求。
