Grease separators are crucial for the performance of sewage systems. Fats, oils and grease – in short: FOG – has some properties that have a negative impact on the performance of the wastewater system. Pipelines and sensors are blocked or sealed by grease deposits within a short time. In holding tanks, grease accelerates the formation of hydrogen sulphide, a toxic and highly odorous gas. Hydrogen sulphide can lead to the formation of sulphuric acid, which then attacks the substance in the pipes. In addition, the purification performance of the wastewater treatment plant is severely impaired. Therefore, grease separators are crucial for wastewater management systems
FOG (Fats, oils and grease) mainly get into the waste water via food residues. Therefore, all waste water from kitchen areas, i.e. from sinks and dishwashers, should first pass through a grease separator before it is discharged into a holding tank. Food waste itself must always be treated separately from waste water. They fall under MARPOL Annex V. This also includes residual water from food waste treatment systems.
BENEFITS OF HAMANN GREASE SEPARATORS FOR WASTEWATER MANAGEMENT SYSTEMS
- Stainless steel design for maximum robustness
- Function after gravity separation
- No moving parts
- TÜV Rheinland certified according to DIN EN 1825-1, DIN EN 1825-2 and DIN EN 4040
HAMANN grease separators work exclusively according to the principle of gravity separation without mechanical parts or additives. Solid food residues are first separated from the waste water by gravity. Then, the fats and oils, which are lighter than water are collected at the top of the separation chamber of the grease separator. From there the collected fats and oils can be drained. A built-in heater keeps the fat liquid so that it can be drained more easily. Separated fats and oils from the grease separator, as well as solid food residues are transfered into external containers via the outlets provided for this purpose and disposed of ashore.
HAMANN grease separators are completely made of stainless steel. This makes HAMANN grease separators extremely robust and reliable.
HAMANN grease separators are the only DIN-certified grease separators for use in the maritime industry. HAMANN grease separators are certified by TÜV Rheinland according to DIN EN 1825-1, DIN EN 1825-2 and DIN EN 4040.
