Comparison of the new millipore HC with conventional membrane filters for the enumeration of fecal coliform bacteria.
Fecal coliform recoveries were determined for six types of membrane filters using 65 nonchlorinated water samples. Results showed that the membranes could be ranked in order of decreasing recovery as follows: Millipore HC greater than Gelman greater than Johns-Manville approximately Sartorius greater than Millipore HA greater than Schleicher & Schuell.
متن کاملInfluence of coliform source on evaluation of membrane filters.
Four brands of membrane filters were examined for total and fecal coliform recovery performance by two experimental approaches. Using diluted EC broth cultures of water samples, Johns-Manville filters were superior to Sartorius filters for fecal coliform but equivalent for total coliform recovery. Using river water samples, Johns-Manville filters were superior to Sartorius filters for total col...

متن کاملEvaluation of membrane filters for the determination of numbers of coliform bacteria in water.
Since the report by Goetz (1947) on the nature and use of membrane filters in Germany, a number of papers have appeared in this country on membrane filter technics for the bacteriological analysis of water. Interest in the use of these membranes was particularly stimulated in 1951 following the publication of papers by Clark et al. (1951) and Goetz and Tsuneishi (1951). These investigators desc...
