Analysers <strong>for</strong> Control in Water Filtration Plants• Variable lags need to be long enough to ensure full mixing of <strong>the</strong> <strong>Chlorine</strong> butshort enough avoiding long sample lines, which create poor control loops• Fixed lags need to be as short as possible and by-pass valves and sample pumpscan be used to reduce delays in long sample lines• Analysers that are used <strong>for</strong> control should have a quick T90 response. TheDepolox 5 and Cl 2 ++ provide a T90 response in less than 20 seconds. The SFCBA provides a T90 response in less than 60 seconds.Page 13Siemens Water & Waste Water AcademyFor internal use only / © Siemens AG 2012. All Rights Reserved.Water Technologies
