Abstract
The standard deals with the biological cleaning of waste gas flows polluted with gaseous substances foreign to air. They apply primarily to the reduction of organic emission components that biodegrade at sufficient speed as well as hydrogen sulphide and ammonia. Their typical field of application comprises mass concentrations of organic compounds up to approx. 1 g/m<(hoch)3>. The processes are designed to reduce emissions that, by virtue of their action principles, are potentially hazardous to health or a source of nuisance. The standard presents an overview of possible solutions and of the associated principles and assessment criteria necessary for correct design.
