  • This 1993 document entitled "Assessment of Sources of Air, Water, and Land Pollution: A Guide to Rapid Source Inventory Techniques" provides techniques for conducting source inventories in Chapter 2 and describes models for estimating air emissions under current controls in Chapter 3. Appendix II includes the United Nations (UN) classification of industries and services.

  • A newcomer to the scene, aerobic granulation is on its way to becoming the hot new technology for high-efficiency wastewater treatment. Thus far, intensive research has been conducted with regard to the understanding of the mechanism of aerobic granulation in sequencing batch reactors (SBR) and its application in treating a wide variety of municipal and industrial wastewater. This basic research has promoted the technology from laboratory-study all the way to the present pilot- and full-scale application.

  • DO NOT have vias between bypass caps and active device – Visualize the high frequency current flow !!! • Ensure Bypass caps are on same layer as active component for best results. • Route vias into the bypass caps and then into the active component. • The more vias the better. • The wider the traces the better. • The closer the bette

  • A study to measure indoor concentrations and emission rates of volatile organic compounds (VOCs), including formaldehyde, was conducted in a new, unoccupied manufactured house installed at the National Institute of Standards and Technology (NIST) campus. The house was instrumented to continuously monitor indoor temperature and relative humidity, heating and air conditioning system operation, and outdoor weather. It also was equipped with an automated tracer gas injection and detection system to estimate air change rates every 2 h.

  • The current study was undertaken in a new manufactured house set up as a research facility. The plan was to conduct longitudinal measurements of VOC concentrations in the house along with measurements of key physical parameters including house air change rate, indoor and outdoor temperature and relative humidity, and wind conditions over a period of approximately one year. The primary objective was to evaluate changes in the emissions of formaldehyde and other VOCs in response to time, house air change rate, and the other parameters.

  • Industrial emissions can be a significant source of particulate emissions in urban areas. The contribution that this source makes to ambient particulate material will vary depending on the location of the industry and the abatement technology adopted. Although many studies have been conducted to characterise emissions from large industrial sources, for example steel works, information on small urban emitters, for example metallurgical processes and small factories, is more limited. Particles emitted from industrial sources have been found to be in the size range 0.

  • Construction activities have significant potential to have adverse environmental impacts. During this phase, often a large transient workforce is employed, workforce numbers tend to peak and material and equipment movements tend to be large. Impacts are typically related to land disturbance caused by earth- works, air emissions from dust, noise from equipment and construction activities and heavy volumes of traf- fic on access roads. In many cases, specialized third party companies and consultants conduct mine construction activities.
