Automatic Grease Separator without Wastewater Lift Pump
（Ideal for above-ground installations where gravity drainage is available.）
Product Overview
The Open-Type Fully Automatic Grease Trap & Oil-Water Separator features an open-top 304 stainless steel tank structure and an intelligent PLC automatic control system. Utilizing a combination of physical separation and dissolved air flotation (DAF) technology, it efficiently separates food waste, grease, and wastewater in a single integrated process.
Designed for continuous automatic operation, the system offers easy installation, low maintenance requirements, and stable effluent quality that meets environmental discharge standards. It is an ideal solution for treating grease-laden wastewater generated in commercial and industrial applications.

Working Principle
Grease-containing wastewater first enters the solid-liquid separation chamber, where food residues and suspended solids are automatically intercepted and discharged.
The wastewater then flows into the oil-water separation zone. By utilizing the density difference between oil and water, combined with dissolved air flotation (DAF) technology, grease rapidly rises to the surface while sludge naturally settles to the bottom. Inclined plate and inclined screen buffering technologies further enhance separation efficiency.
The built-in temperature control system maintains grease fluidity, ensuring reliable operation year-round. Floating grease is automatically collected and removed by the skimming system, while settled sludge can be periodically discharged through a bottom drain valve.
The treated water is then discharged in compliance with environmental standards.
