Estimation of Wastewater-Generated Viral Aerosols

Virus Sampling in Wastewater - Field Experiences
Membrane adsorption, chemical precipitation, and soluble alginate filtration methodologies have been combined in the development of a relatively simple yet sensitive procedure for detecting...

Trihalomethanes and Viruses in a Water Supply
In June 1975, a program was established for monitoring viruses and volatile organics in the Occoquan Reservoir and water service area supplying approximately 600,000 residents of northern...

Persistence of Virus on Sewage-Irrigated Vegetables
A number of municipalities are contemplating land disposal of primary and secondary-treated sewage in an attempt to reduce stream pollution. Presently operating sewage treatment systems...

Virus-Coal Sorption Interaction
An investigation was made on the sorption interaction of coal and a model virus, bacterial virus MS2 versus Escherichia coli. Bituminous coal...

Fate of Wastewater Bacteria and Viruses in Soil
Bacterial survival in soil is affected by moisture content, temperature, organic matter, and antagonism by soil microflora. In most instances the survival of bacterial pathogens in the...

Recycling Allows Zero Wastewater Discharge
St. Petersburg, Florida, committed itself to total recycling of its wastewater with zero discharge to its surrounding bays. They plan to accomplish that goal through land disposal techniques....

Virus Removal by Diatomaceous Earth Filtration
An investigation was made to determine the removal of bacteria viruses, T4 and MS2, by filtration through uncoated and polyelectrolyte coated diatomaceous earth (DE). Using a bench scale...

Ecology of Blue-Green Algal Viruses
Blue-green algal viruses have wide geographical distributions and are present in both fresh water and marine environments. Population control of Plectonema boryanum,...

f2 Coliphage as Tracer in Wastewater Basin
In an effort to find a suitable tracer to determine virus flow-through in a sedimentation basin, the f2...

Persistence of Virus and Bacteria in Seawater
At a temperature of 38–40° F bacterial survivals (Escherichia coli) were significantly enhanced in seawater deliberately polluted with small...

Virus Removal and Inactivation by Physical-Chemical Waste Treatment
A prototype of a packaged sanitary wastewater treatment system employing physical-chemical processes was evaluated for its ability to remove and inactivate enteric viruses. The treatment...

Biological Control of Aquatic Weeds
Biological control is a cheap, permanent, and nontoxic method of controlling aquatic weeds. Insects and fish are the most effective biological agents. The use of herbivorous fish in the...

Destruction of Bacteria and Viruses in Seawater
Marine microbial predators destroy enteric bacteria in seawater. Viruses are destroyed by unknown marine microbial antagonists and by a toxic chemical component of the seawater. Viruses...

Natural Virus Inactivation Processes in Seawater
Data are presented which indicate that seawater possesses antiviral properties of a biological nature associated with specific marine bacteria. Twelve samples of natural seawater from...

Viral Disinfection of Estuarine Water by UV
Experiments were conducted with viruses artificially introduced into seawater under both static and continuously flowing conditions. Under static conditions, the devitalization of each...

Inactivation of Virus in Sewage
Inactivation of virus in sewage effluent was investigated using a rapid sampling reaction system. The effects of pH and varied reaction conditions are reported. Data presented strongly...

Integrated Approach to Problem of Viruses in Water
Large numbers of viruses enter water intakes daily. The inability of epidemiologists to detect waterborne transmission may be the result of preoccupation with disease rather than infection...

Biological Control of Intestinal Bacteria and Viruses

Engineering Evaluation of Virus Hazard in Water
The evaluation is presented in terms of 13 questions: What virus infections may be spread through water? How important is water in transmitting virus disease? Can the coliform index be...
