Use of a disposable filtration capsule with a non-occluded membrane filter element in the place of a standard spiral wound cartridge allows for the more rapid and quantitative filtration, recovery, and quantitation of microorganisms in liquid, particularly surface waters, well water, tap water, and the like. The capsule allows a severe reduction in the water sample size tested, substantially minimizes risks of cross-contamination, and provides a leak-proof vessel for shipment. Risk of infection of laboratory personnel and time of analysis are both reduced. Costs of measuring contamination by microorganisms such as Giardia and Cryptosporidium is lowered significantly while increasing the accuracy and dependability of the measurement.

[ What is claimed is:] [1.] A method for the quantitation of microorganisms in a suspected microorganism-containing fluid sample comprising:a) connecting a suspected microorganism-containing fluid sample source to a sample inlet of a disposable filtration capsule;b) flowing a known volume of said suspected microorganism-containing fluid sample through said disposable filtration capsule, said disposable filtration capsule comprising a polymeric housing having a sample inlet and an outlet; positioned between said sample inlet and said outlet a non-occluded filter element comprising a membrane such that all fluid flowing from said sample inlet to said outlet must pass through said filter element and wherein microorganism-containing sediment is trapped on an upstream side of said filter element, said disposable filtration capsule having an elution effective void volume;c) decanting liquid and the sediment from the upstream side of said filter element through said sample inlet of said disposable filtration capsule in the form of an initial eluate;d) quantitating one or more target microorganisms from said initial eluate.
