摘要 |
Water sensor has membrane and filtrate chamber with analytical device suitable for on-site measurement of water treatment parameter without supply of fresh water. A water supply and waste water analytical assembly with a water sampler. The assembly incorporates an analytical instrument (26) to determine one or more water parameters. The assembly further has a membrane (20) which separates a sample chamber (16) from a filter chamber (22), and a tube (24) linking the filtrate chamber (22) to the analytical instrument (26). The filtrate chamber (22) is linked with the permeate chamber (34). The membrane (20) is cleaned by back-flushing (30-38) from the filtrate chamber (22) using water from the permeate chamber (34). Also claimed is a process to clean a filter membrane within the sampler and forming part of a water supply and waste water analytical instrument. |
