摘要: The strategy of the Metropolitan Water District Southern California (MWDSC) for coping with difficult earthy-musty odors encompasses sensory, microbiological, and trace organic analytical techniques. closed-loop stripping analysis (CLSA) technique allows identification several tasteand odor-causing substances (e.g., geosmin 2-methylisoborneol) in water, sediments, cultures at low nanogram-per-litre levels. CLSA is as sensitive or more than human nose qualitatively reliable. Extensive data assembled before during odor episodes, along multiple sources raw water a flexible distribution system, enable MWDSC to control odors.
