Dissolved Oxygen Utilization as an Indicator of Total Microbial Activity on Non‐metallic Materials in Contact with Potable Water

摘要: The technique for the assessment of growth micro-organisms on non-metallic materials in contact with potable water employs standard microbiological counting techniques and a subjective visual to measure microbial activity that occurs test procedure. An alternative method assessing based utilization dissolved oxygen is described compared existing method. was found be suitable alternative, main advantages being reproducibility results reduction cost test.
