Microbial characterization of biological filters used for drinking water treatment
Article Abstract:
The study characterized the microbial community found in biological filters used in the treatment of drinking water from the Ohio River. Depth profiles were also constructed for the microbial community structures using phospholipid fatty acid analysis. Fingerprinting by arbitrarily primed polymerase chain reaction as well as assessments of carbon source utilization patters were also performed. Preozonation and filter depth served as the basis for the differentiation of microbial communities from the profiles collected.

Filtration sizes of human immunodeficiency virus type 1 and surrogate viruses used to test barrier materials
Article Abstract:
Effective transmission diameters of human immunodeficiency virus type 1 (HIV-1), herpes simplex virus type 1 (HSV-1) and four bacteriophages as surrogate viruses were evaluated using well-defined- holed filters in a study conducted to verify if a virus particle may pass through a hole whose diameter is greater than the diameter of that particle measured from electron micrographs. Results of the study were consistent with the statement but with low transmission values.

Measurement of biocolloid collision efficiencies for granular activated carbon by use of a two-layer filtration model
Article Abstract:
Clean-bed filtration theory was used to study the relative adhesion of different biocolloids and latex microspheres in packed beds of granular activated carbon (GAC). This proved that GAC is an effective material for removal of bacteria and phage and that GAC particle size is an important factor than relative stickiness for effective particle removal.
