Biological methods
Biological cleaning methods are used to decompose fats and fibres in the biofilm, as well as phenols, proteins and mineral oils. They are also applied to eliminate or reduce odour nuisances [Baig1976] [Jense1977].
A two-components detergent is mainly used in sewage systems of hospitals, kitchens, large cafeterias and the food processing industry [FI-Aladi].
