Fully Automatic Operation
Integrated controls automate key treatment functions, reducing routine manual intervention and simplifying daily operation.
Automatic Commercial Kitchen Oil-Water Separation Systems
Open-Type Fully Automatic Oil-Water Separator for Commercial Kitchens
The Open-Type Fully Automatic Oil-Water Separator is designed for commercial kitchens and foodservice facilities that generate large volumes of wastewater containing fats, oils, grease and food residues. The system integrates solid residue separation, oil-water separation, grease collection and automatic control into one stainless steel treatment unit. Wastewater passes through multiple treatment stages to separate solid waste and floating grease before the treated water is discharged to the downstream drainage system. Automatic operation helps reduce manual handling and routine maintenance workload, while the accessible structural design makes inspection, cleaning and servicing more convenient. It is suitable for restaurants, hotels, shopping malls, central kitchens, canteens, food processing facilities and other projects requiring centralized treatment of grease-containing kitchen wastewater.

CORE ADVANTAGES
Designed for selection, access and service
Efficient Oil-Water Separation
The internal separation process helps isolate floating fats, oils and grease from kitchen wastewater before downstream discharge.
Automatic Solid Waste Management
Food residues and suspended solids can be separated before the main oil-water treatment stage, helping protect downstream components.
Automatic Grease Collection
Separated grease can be directed toward a dedicated collection area or container, making grease handling cleaner and more convenient.
High-Capacity Commercial Design
Designed for centralized wastewater treatment in restaurants, food courts, central kitchens and other high-volume foodservice facilities.
Durable Stainless Steel Structure
The stainless steel construction provides corrosion resistance, durability and easy-to-clean surfaces for demanding kitchen environments.
Intelligent Control System
An integrated control panel provides centralized equipment operation and monitoring for more convenient system management.
Easy Inspection & Maintenance
Accessible treatment sections, discharge connections and service points simplify routine inspection, cleaning and maintenance.
Project-Based Customization
Treatment capacity, connection sizes, internal configuration and control functions can be matched to different wastewater and installation requirements.
HOW IT WORKS
A clear process path
- 1
Wastewater Intake: Grease-containing kitchen wastewater enters the separator through the inlet.
- 2
Solid Separation: Food residues and larger solids are separated from the wastewater stream.
- 3
Residue Collection: Separated solid waste is directed to the designated collection container.
- 4
Oil-Water Separation: Fats, oils and grease rise and separate from water inside the treatment chamber.
- 5
Grease Collection: Separated grease is transferred or discharged to the dedicated grease collection container.
- 6
Water Clarification: The remaining wastewater passes through the internal separation stages for further treatment.
- 7
Treated Water Discharge: Separated wastewater flows to the downstream drainage system.
- 8
Automatic Cycle Control: The control system manages the operating cycle and prepares the equipment for continuous treatment.

FAQ
Before you request a model
What is an open-type fully automatic oil-water separator?+
It is a commercial kitchen wastewater treatment system designed to automatically separate food residues, fats, oils and grease from wastewater before discharge.
What does “fully automatic” mean?+
It means key operating processes can be managed automatically by the equipment control system. The exact automation functions depend on the selected model and configuration.
Can it separate both food waste and grease?+
Yes. The system can be configured to remove larger food residues before the wastewater enters the main oil-water separation section.
How does the oil-water separation process work?+
It mainly utilizes differences in physical properties and density between grease and water, allowing floating fats and oils to separate from the wastewater.
Can separated grease be collected automatically?+
Depending on the selected configuration, separated grease can be directed or transferred into a dedicated external collection container.
Does it require regular manual cleaning?+
Routine inspection and maintenance are still required, but automated residue and grease management can significantly reduce manual cleaning workload compared with basic grease traps.
Is it suitable for large commercial kitchens?+
Yes. It is suitable for high-volume commercial kitchens when the treatment capacity is correctly matched to peak wastewater flow and grease load.
Can it be used in shopping mall food courts?+
Yes. It is suitable for centralized kitchen wastewater treatment in shopping malls, food courts and multi-restaurant commercial facilities.
Can the equipment help reduce drain blockages?+
Removing food residues and grease before wastewater enters downstream drainage pipes can help reduce grease accumulation and blockage risk.
Is the equipment stainless steel?+
The product shown features a stainless steel structure. The exact stainless steel grade should be confirmed according to the final equipment specification.
How do I select the correct treatment capacity?+
Selection should be based primarily on peak wastewater flow, kitchen scale, meals served, grease load, operating hours and connected drainage points.
Can the equipment be customized?+
Project-specific treatment capacities, pipe connections, layouts and control configurations may be available depending on installation requirements.
Does this model include wastewater lifting?+
This product is primarily positioned as an oil-water separation system. If the project requires wastewater to be pumped to a higher drainage point, a lifting module or separate wastewater lifting system should be selected according to site conditions.
What information is required for a quotation?+
Please provide wastewater flow, kitchen type, meals per day, pipe sizes, installation dimensions, voltage and project destination. Drawings and site photos are also helpful.
