Polycyclic aromatic hydrocarbons (PAHs) are a class of well-know roxic and carcinogenic compounds that are widely present in industrial waste, gas, automobile exhaust, coal tars, cigarette smoke and meat products, which constitute the most common ways of exposure of humans to the PAHs (Castillo et al. 2004). PAHs are listed by the US Environmental Protection Agency (USEPA) as priority pollutants.
Problem: Un-covered anaerobic systems can generate significant amounts of odors and renewable energy in the form of methane. The sulfides and methane are lost to the atmosphere due to lack of an impermeable barrier. If the basins were covered, the biogas could be captured, burned and converted to electricity and odors contained. A Missouri project, believed to be the largest and most comprehensive livestock manure-to-energy of its type in the world, is currently under way. The existing facultative basins collect...
The capability to convene a multi-agency Air Quality Cell (AQC) was established in England in 2009 following the Buncefield Oil Storage Depot incident. A review of this event identified the need to rapidly co-ordinate the acquisition, analysis and interpretation of air quality data in major incidents. Arrangements have been made in England to bring together experts from the Environment Agency (EA), Public Health England (PHE) and the UK Meteorological Office on a 24/7, 365 days and year basis to form an AQC for...
In greenhouse applications, the accurate measurement of a number of environmental parameters such as carbon dioxide concentration, temperature, light intensity, water, humidity, pH and nutrient levels using sophisticated sensors is used to create a controlled environment for optimising plant growth rates while minimising energy usage.
Carbon dioxide concentration is also one of the best indicators of air quality in offices, schools and other inhabited buildings since it is produced by the people occupying the...
AVA has developed systems for pre-treating hazardous waste prior to incineration, which leads to higher throughput performance in combination with lower construction and maintenance costs and additional low pollution emissions, in comparison to conventional techniques. The system is based on the principal that constant gross calorific values and regular piece sizes together with consistency of the fuels being charged forms the basis for a highly effective incineration. Many of these pretreatment plants for...
Summer 2015 marked the completion of two years successful operation of an ERG (Air Pollution Control) Ltd designed, installed and commissioned waste gas treatment plant at the Saffil production facility in Widnes.
Background
Saffil Ltd, a wholly owned subsidiary of Unifrax, produces high temperature insulation products, for use in automotive catalytic convertors and other automotive and industrial applications. From a production facility in Widnes, Saffil produces alumina‐silicate polycrystalline wool...
