WebLimit value of turbidity according to Drinking Water Ordinance The Drinking Water Ordinance (TrinkwV Annex 3, Part I, No. 18) stipulates that the water at the outlet of the waterworks may have a maximum turbidity of 1.0 NTU. All the turbidity values determined with the turbidity meter on the treated drinking water must be below this limit. WebDilute 25mL of the formazine turbidity concentrate to 1 litre with turbidity free distilled water to obtain 250 ppm or 100 NTU for setting '100' of the instrument. Note: Formazine standard 100 NTU should be prepared weekly. Procedure (1) Switch the instrument on. (2) Open the lid of the sample compartment.
