Grease & Oil Separators

Complete guide to choosing a grease and oil separator

Choosing the right separator system is crucial to ensure stable operation, prevent emergency shutdowns and comply with municipal environmental regulations. Both grease and mineral oils can cause serious damage to pipelines and disrupt the biological processes of wastewater treatment plants if discharged untreated.

The difference between grease separators and oil separators

• Grease separators: Used primarily in businesses that handle food, such as restaurants, bakeries, catering kitchens and slaughterhouses. They separate animal and vegetable fat from wastewater before it reaches the sewage system, which prevents grease plugs from forming in the pipes.
• Oil separators: Installed in areas where mineral oils, fuels or sludge may occur, such as car repair shops, car washes, parking garages and industrial properties. The system effectively separates oil droplets and petroleum products from stormwater and wastewater.

Important accessories for complete and approved operation

A fully functioning separator system requires more than just the separator tank itself. To meet standards and simplify maintenance, customized accessories are often needed:

• Level alarm and oil alarm: Automatically monitors the layer thickness of grease or oil and alarms at high sludge and sludge levels so that emptying occurs at the right time.
• Sampling wells: Placed after the separator to enable accurate and representative sampling of outgoing water according to regulatory requirements.
• Telescopic shaft and covers: Provides flexible adaptation to ground level and ensures the correct load class for walking or driving surfaces.
• Anchoring kits: Secures the tank against uplift in the event of high groundwater pressure.

Factors to consider before purchasing

Before dimensioning and ordering, it is important to map the specific conditions of the operation. Check the maximum design flow (nominal size, NS) based on connected taps or drainage areas. Also ensure whether the installation will take place indoors in the basement or outdoors in the ground, and check local requirements from the municipal environmental and water management administration regarding emptying intervals, sampling and alarm functions.
