With membrane filtration, microorganisms are retained by a 0.45 µm pore size filter, and all inhibiting compounds are rinsed using a suitable rinse solution.
In either case, a new sample must be run using a dilution that will give 20–80 coliform colonies per filter. When testing nonpotable water, if no filter
