In companies which produce wastewater containing grease, grease separators must be installed in accordance with DIN EN 1825 and DIN 4040-100. According to this, grease separator systems must always be used when greases and oils of organic origin have to be kept out of the washwater. Typical areas of application are thus butchers shops, slaughterhouses or frying and canteen kitchens. The nominal size of the separator mainly depends on the wastewater quantity.
