Process technology

Industrial or trade wastewater from catering facilities must also be treated by passing it through a grease separator before it is discharged into the public sewers. However, some municipalities require further wastewater treatment for additional protection of the sewer network and wastewater treatment plant. Process wastewater from a large catering kitchen can usually not be precleaned sufficiently by grease separators. ACO has developed further wastewater treatment methods, based on biological or chemical-physical cleaning methods.

For example, where economic efficiency and sustainability factors are concerned, operating costs can be compensated and energy can be saved by using a new type of heat exchange for wastewater from grease separators with output-controlled heat pump.
