# Commission Implementing Decision (EU) 2018/1147 of 10 August 2018 establishing best available techniques (BAT) conclusions for waste treatment, under Directive 2010/75/EU of the European Parliament and of the Council (notified under document C(2018) 5070) (Text with EEA relevance), Division: Description

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

Implementation of a manual and/or automatic monitoring system to:
ensure a stable digester operation;
minimise operational difficulties, such as foaming, which may lead to odour emissions;
provide sufficient early warning of system failures which may lead to a loss of containment and explosions.
This includes monitoring and/or control of key waste and process parameters, e.g.:
pH and alkalinity of the digester feed;
digester operating temperature;
hydraulic and organic loading rates of the digester feed;
concentration of volatile fatty acids (VFA) and ammonia within the digester and digestate;
biogas quantity, composition (e.g. H2S) and pressure;
liquid and foam levels in the digester.
