Working Principle

The Semi-Automatic Grease Trap & Oil-Water Separator utilizes a multi-stage treatment process that combines solid-liquid separation, oil-water separation, automatic grease skimming, and thermostatic heating to efficiently treat grease-laden wastewater.

Wastewater first enters the unit through a debris filtration basket with 5 mm perforations, where food residues and solid particles are effectively intercepted. The pre-filtered wastewater then flows into the oil-water separation chamber, where grease naturally rises to the surface due to the difference in density between oil and water.

The accumulated grease is automatically removed by the skimming system and directed into the oil collection chamber before being discharged into an external oil storage container.

Meanwhile, the intelligent temperature control system maintains an optimal operating temperature through integrated heating elements, preventing grease solidification and ensuring smooth wastewater flow and separation performance.

After treatment, the clarified wastewater can be discharged directly in accordance with local wastewater discharge requirements.
