# Commission Implementing Decision (EU) 2019/2031 of 12 November 2019 establishing best available techniques (BAT) conclusions for the food, drink and milk industries, under Directive 2010/75/EU of the European Parliament and of the Council (notified under document C(2019) 7989) (Text with EEA relevance), Division: DEFINITIONS

Extent: E+W+S+N.I.

For the purposes of these BAT conclusions, the following definitions apply:
Term used
Definition
Biochemical oxygen demand (BODn)
Amount of oxygen needed for the biochemical oxidation of the organic matter to carbon dioxide in n days (n is typically 5 or 7). BOD is an indicator for the mass concentration of biodegradable organic compounds.
Channelled emissions
Emissions of pollutants into the environment through any kind of duct, pipe, stack, etc.
Chemical oxygen demand (COD)
Amount of oxygen needed for the total chemical oxidation of the organic matter to carbon dioxide using dichromate. COD is an indicator for the mass concentration of organic compounds.
Dust
Total particulate matter (in air).
Existing plant
A plant that is not a new plant.
Hexane
Alkane of six carbon atoms, with the chemical formula C6H14.
hl
Hectolitre (equal to 100 litres).
New plant
A plant first permitted at the site of the installation following the publication of these BAT conclusions or a complete replacement of a plant following the publication of these BAT conclusions.
NOX
The sum of nitrogen monoxide (NO) and nitrogen dioxide (NO2), expressed as NO2.
Residue
Substance or object generated by the activities covered by the scope of this document, as waste or by-product.
SOX
The sum of sulphur dioxide (SO2), sulphur trioxide (SO3), and sulphuric acid aerosols, expressed as SO2.
Sensitive receptor
Areas which need special protection, such as:
residential areas;
areas where human activities are carried out (e.g. neighbouring workplaces, schools, day-care centres, recreational areas, hospitals or nursing homes).
Total nitrogen (TN)
Total nitrogen, expressed as N, includes free ammonia and ammonium nitrogen (NH4-N), nitrite nitrogen (NO2-N), nitrate nitrogen (NO3-N) and organically bound nitrogen.
Total organic carbon (TOC)
Total organic carbon, expressed as C (in water), includes all organic compounds.
Total phosphorus (TP)
Total phosphorus, expressed as P, includes all inorganic and organic phosphorus compounds, dissolved or bound to particles.
Total suspended solids (TSS)
Mass concentration of all suspended solids (in water), measured via filtration through glass fibre filters and gravimetry.
Total volatile organic carbon (TVOC)
Total volatile organic carbon, expressed as C (in air).
