Abstract
The most retentive glass fibre filters were able to retain almost all bacteria from the water of an oligotrophic lake. Having satisfactory speed and capacity, of filtration this type of filter is quite near to the ideal which should be able to include all algae and bacteria in the category of particulate organic carbon. Similar retention could also be achieved by silver filters but, because of their high blank values, price, and lower filtration speed and capacity, they are not able to compete with glass fibre filters in practical work.
