The primary function of an air handling system for any type of clean room is to control the level of airborne contaminant particles by constantly filtering and recirculating the air. The arrangement of a system depends on whether it is to be a conventional clean room, unidirectional vertical or horizontal flow clean room.

The concentration of a contaminant refers to its quantity in the air. For gaseous contaminants, the concentration is expressed as a ratio of the volume of contaminants present in one billion volumes of air, or ppb. A similar unit is the parts per ten million, or pptm. One pptm consists of 100 ppb. For particulates, the concentration is expressed as a ratio of the mass of the particulates present in one cubic metre(m³) of air. The unit used for the mass is the microgram²(or µg), so the concentration is expressed in units of mg/m.  2, record 3, English, - part%20per%20ten%20million

Air stripping is a technology in which volatile organic compounds(VOCs) are transferred from extracted water to air. Typically, air stripping takes place in a packed tower(known as an air stripper) or an aeration tank. The air stripper includes a spray nozzle at the top of the tower. It sprays groundwater that has been pumped to the surface over the packing in the column. As the water descends, air is forced up through the column, stripping off the volatile compounds.... Air strippers transfer contaminants from one medium to another. There is no destruction of the contaminant. Consequently, the risks of emitting pollutants into the air must be carefully evaluated. Often, the air stream(or off-gas) is treated before it is emitted to the atmosphere.  2, record 6, English, - air%20stripping

The adverse effects of either a pollutant, a contaminant or quantities of both, on normal air or water is called contamination. Thus, water may contain sewage in suspension and can be classified as "polluted", but it is not contaminated unless it contains, at the same time, sufficient pathogenic bacteria to impart disease to animals or humans. It may also be polluted and contaminated if it contains harmful quantities of lead, mercury, etc., from man-made sources. But it is only considered contaminated if no man-made pollution is present and the undesirable concentrations of mercury and lead came from runoff over natural deposits of these elements.  3, record 7, English, - contamination

Enclosure hoods are designed to enclose the emission source. Examples of enclosure hoods include paint spray booths, laboratory hoods, belt conveyor enclosures, bin or hopper enclosures and abrasive blasting cabinets. These hoods allow contaminants to disperse within the enclosed space, but prevent stray air currents from carrying the contaminant into the work area.  2, record 19, English, - paint%20spray%20booth

Enclosure hoods are designed to enclose the emission source. Examples of enclosure hoods include paint spray booths, laboratory hoods, belt conveyor enclosures, bin or hopper enclosures and abrasive blasting cabinets. These hoods allow contaminants to disperse within the enclosed space, but prevent stray air currents from carrying the contaminant into the work area. The dispersed contaminants are subsequently withdrawn from the enclosure by exhaust ventilation.  1, record 20, English, - enclosure%20hood

Enclosure hoods can be designed to completely seal the emission source (total enclosure) or to allow access to the interior of the enclosure (partial enclosure). In theory, there is no need for exhaust ventilation in total enclosures.  1, record 20, English, - enclosure%20hood
