Filter Sampling Procedures Filter media samples
should be collected when the filter is offline and the media has settled.
Ideally, larger filter beds would be sampled in multiple locations to observe
the change in mineral and biological conditions throughout the filter. Sample the media in a
minimum of two locations: first, near the surface of the media and a second
at the mid-point of the total depth of the media. If the media is greater
than 3 foot in depth, a third sample at the deepest mark should be collected.
Gather approximately 200 grams (0.5 lb) of media per sample, and seal in a
container with sufficient water from the filter to keep the media moist and
wetted. The sample container should be marked with the filter id, depth of
sample, and date sampled. You should
not use any type of preservative in the sample and of ship to our lab
immediately. UPS offers daily drop off
at our laboratory and some very competitive 2nd and 3rd day delivery rates. Pressure or kettle type filters should be
sampled in a manner that allows an effective representation of fouling
present to be observed. Please contact our office to discuss the best
sampling procedures for these types of filters. Exceptions to this sampling method can be
made, but should be noted. You may also want to
draw a water sample to represent the static conditions within the filter, or
pre and post treatment water samples, for more information as needed. Please send any
additional operating information as well as your questions and objectives in
having the analysis performed. Send samples
