Controlling Odor and Gaseous Emission Problems from Industrial Swine Facilities: A Handbook for All Interested Parties

Aerobic ó bacteria that require molecular oxygen as an electron receptor

Anaerobic ó bacteria that can only function incomplete absence of molecular oxygen which can be quite toxic

Air Scrubbers - technique where air is forced up through a shaft while water flows down the shaft, trapping odorous gases and particles.

Biological Oxygen Demand (BOD) ó the amount of oxygen required to decompose all of the biodegradable organic wastes in a given volume of water during a 5-day period

Chemical Oxygen Demand (COD) ó the amount of oxygen required for the chemical conversion of organic waste matter

Biodegredation - the breakdown of organic matter by bacteria

Biofilters - filters constructed of biologically active materials, such as compost, straw, wood chips, peat or soil, that contain microorganisms that break down volatile organic compounds and oxidizable inorganic gases and vapors into non-malodorous compounds such as water and carbon dioxide

Biogas - gas generated by bacteria during the decomposition organic matter, the components of which include methane, carbon dioxide and trace levels of organic gases such as hydrogen carbon monoxide, nitrogen, oxygen and hydrogen sulfide

Facultative ó bacteria that utilize free oxygen when it is available and use other substances as electron receptor (i.e. oxidants such as nitrate and sulfate ions)

Farrow ó (verb) to give birth to a litter of pigs; (noun) a litter of pigs

Farrow-to-Finish - Swine operation encompassing from birth to slaughter/death

Gestational ó pregnant

Geographical Information Systems (GIS) - airborne and satellite remote sensing of geographical areas used to create an integrated database that combines a computerized map product with layers of information about the manmade and natural features of the land; enables users to collect, analyze, manage and access all types of data related to the land

Mesophilic - temperature range of 90 - 110†F

Methanogenic - bacteria that produce methane while breaking down organic matter

pH ó a value used to express acidity and alkalinity (scale 1 to 14, with 1 being very acidic and 14 very being alkaline; water typically has an a pH value of 7)

Thermophilic - temperature range of 120 - 140†F
