As knowledge and understanding of the composition of air and the nature of airborne contaminants and their effect on people has grown, so has the desire to minimize exposure to airborne contaminants. Alongside this, it has been necessary to consider how to measure the effectiveness of the air filters designed...
Biomass gasification processes generate organic contaminants in the exit gases that are generally referred to as tar. Before use of the gases in a boiler, engine or turbine, particulate matter and the organic tar must be removed, or reduced to a level that is acceptable to end user requirements. One...
THE ENVIRONMENTAL Protection Agency EPA has issued a final rule that requires public water systems to monitor for 15 additional chemical contaminants in drinking water. The regulation, which took effect upon publication in the Federal Regis THE ENVIRONMENTAL...
From the executive summary: ‘Backflushing involves reversing the flow of materials generally liquids to flush contaminants from some type of filtering device. Water treatment plants are a good example where water is filtered through sand to remove impurities; periodically they will reverse the flow through the sand to force...
This paper describes a research program that was conducted to define natural gas contaminant levels necessary to insure that internal corrosion of compressed natural gas CNG cylinders does not constitute a hazard over the lifetimes of the cylinders. A literature search was performed and companies in the natural gas transmission...
