Grease Trap Maintenance
The main use of the Grease Traps is to separate OIL & FAT from the water or any other working liquid.

From that point of view, the ideal working media would be-just a mechanical mixture of such components.

Unfortunately, in reality in the working conditions where the Grease Traps are used, the working media incorporates many other components including mechanical particles of the organic and non-organic source.

In order to prevent these mechanical components to enter the sewerage systems and block them, Grease Traps incorporate the mechanical drainage components that keep all the mechanical parts bigger than the design size, stay inside the G/T.

Therefore, in order to keep G/T functioning as per designed standards, it is required to perform regular maintenance, based on the following main activities:
  • Empty the accumulated sediments
  • Empty the accumulated oil and grease
  • Keep feed and discharge connections and pipe lines at the design flow rate
  • Keep the Perforated drainage parts of the Grease Trap at the design flow rate
It is impossible to create a universal timing schedule for the maintenance of Grease Traps, because it depends of their usage. User has to follow up and establish such timing based on the realistic working conditions.

However the main rule is not to allow Grease Traps to get blocked, so their main function is not prevented.

Maintenance Procedures

The following basic steps are to be performed during the cleaning process of the Grease Trap:
  • Remove the fastening Star Bolts from the G/T Lid (where applicable);
  • Lift the G/T Lid, and turn it around so the top face of the lid is facing the floor, in order to prevent dripping;
  • Wash and clean the G/T Lid Inside and outside;
  • Remove G/T Basket (Baskets) and empty them into adequate waste bin;
  • Clean the G/T Baskets of all the sediments, inside and outside;
    • IMPORTANT NOTE: Collected waste and sediments MUST NOT be washed in to the sewerage or any other drainage system, but it must be sent to the proper deposition yard.
  • Wash all the G/T Baskets, making sure that perforated draining areas are clean and that holes are not blocked;
  • Clean the G/T Tank of all the sediments. Make sure that discharge and feed pipe connections are also cleaned and that they have free flow;
  • Wash the G/T tank inside and outside;
    • IMPORTANT NOTE: Where applicable open all the valves (Discharge, Overflow etc.) and wash them thoroughly.
  • Inspect G/T Tank and Baskets for cracks and damages and repair if necessary in order to prevent leaking;
  • Place the G/T baskets in to the G/T tank, making sure that they are properly positioned at the basket seats;
  • Put the G/T Lid on to the G/T Tank and fasten the Star Bolts (Where applicable)
