Ecoflo® Peat Filters
Sampling Guide – USA-NSF
Sampling
When the Ecoflo® Peat filter effluent needs to be evaluated, a sampling protocol must be followed. The sampling method could
be different depending on the type of parameter to analyze (grab sample or 24 hour sample).
Note: the technician must be trained before sampling. Therefore, the following procedure is to be used as a reminder after the
training has been completed.
The expected treatment efficiency of the Ecoflo® treated effluent as established through analytical methods described in
NSF/ANSI Standard 40 is:
