Waterenvironmental control and process refinement inside a wastewater treatmentplant WWTP is fundamentally based on sampling, analysis and on-linemeasurements on water and sludge streams. The problems related to an accurateand reliable control and thus an efficient water protection are addressed inthe following. Four different crucial points whenever a sampling and controlscheme is planned: 1 Where should a sampling and on-line measurement take place?2 When should sampling take place? 3 How should the sampling and on-linemeasurement take place? 4 Which variables should be controlled? Examples aregiven from different plants demonstrating ways to address the questions.Especially the relevance of the adopted parameter BOD Biochemical OxygenDemand is discussed. It is finally suggested to even abandon the use of BOD asconsent variable in favor of on-line measurement of Suspended Solids, Nitrogenand Phosphorous.

KEYWORDS
