Fresh grease separator plant Lipator-S-RA/Lipator-P-RA
1.2 Designing drainage systems
Wastewater, in which a noteworthy part of the fats exists in non-separable (emulsified)
form, can only be treated effectively in grease separators which operate using the gravity
principle under certain conditions.
Examples:
■
Wastewater from dairies, cheese dairies, slaughterhouses, fish and meat processing
companies
■
Wastewater from catering service companies, e.g. catering establishments in which
pure dishwashing operation exists
■
Wastewater from waste treatment units
The design must provide for separation of the wastewater substreams, by type, quantity
and state of the wastewater contents. In this way the wastewater substreams can be
treated optimally and the retained substances disposed of properly. If the formation of
stable emulsions in the wastewater cannot be prevented, special wastewater treatment
units are required, e.g. ACO LipuFloc or ACO BioJet.
1.3 Operational regulations
The installation and operation of grease separators is subject to legal provisions and
regional regulations (e.g. respective local byelaws). Further information is available from
the competent authorities. The following standards are listed for orientation purposes and
are to be added to and checked that they are current.
