Residual Chitosan Acetate Field Test - Instructions Manual

A one liter (1000mL, or ~1qt.) wide mouth container is provided for sample collection. Collect 1L of sample into this clean container. The sample should be fairly clear and of low turbidity, less than 10 Nepthalometric Turbidity Units (NTU.) Collect the sample from the outflow area of the treatment system. For active CESF treatment, collect the sample in the effluent at the end of the treatment system. Place 5 drops of color enhancement solution into the sample, then mix by stirring or gently swirling with the lid on.  You do not need to pH adjust the sample. This test can be run at virtually any pH, usually pH 2-10.
