Project Background

With the increasing development of underground commercial spaces, many restaurants and food service facilities are now located in basement areas, including B1 and B2 floors.

This project was installed for a commercial kitchen located on the second basement floor (B2).

Because the kitchen drainage point was lower than the municipal sewer connection level, conventional gravity drainage could not meet the discharge requirements.

Kitchen wastewater contained:

• Food residues

• Solid particles

• Cooking grease and oil

• Cleaning wastewater

Without proper treatment, direct discharge could cause:

• Grease accumulation inside pipes

• Drainage blockage

• Unpleasant odors

• Higher maintenance costs

• Non-compliant wastewater discharge

Therefore, the project required an integrated solution combining:

Grease separation + wastewater lifting

Project Solution

To solve the drainage challenge in the underground kitchen, we supplied:

Closed Automatic Grease Separation & Lifting System

The system integrates:

Wastewater collection → Solid separation → Grease separation → Wastewater lifting

Providing a reliable drainage solution for basement commercial kitchens.

On-site Installation Completed

The equipment was successfully installed and connected with the kitchen drainage system.

It is designed for applications including:

✅ Basement restaurants
✅ Underground commercial kitchens
✅ Parking garage food facilities
✅ Projects with drainage level differences

The built-in lifting system transfers treated wastewater to the municipal sewer line efficiently.

Three-stage Separation & Filtration System

The equipment adopts a multi-stage separation design:

1. Solid Waste Separation

The first stage removes solid particles from kitchen wastewater:

• Food scraps

• Vegetable residues

• Larger impurities

Reducing the risk of pipeline blockage.

2. Grease Separation

Based on the density difference between oil and water:

• Grease is separated and collected

• Less oil enters the drainage system

• Improves wastewater discharge stability

3. Wastewater Lifting

After separation, treated wastewater enters the lifting chamber:

• Automatic pumping

• Overcomes basement drainage height differences

• Transfers wastewater to the required discharge point

Closed Tank Design for Better Hygiene

Compared with traditional open grease traps, this system adopts:

A fully enclosed tank structure

Benefits:

✅ Reduces direct exposure of grease and wastewater
✅ Helps minimize odor release
✅ Improves underground kitchen hygiene
✅ Suitable for long-term commercial operation

Easy Residue Cleaning & Maintenance

Designed for daily restaurant operation:

• Centralized residue collection

• Simple cleaning access

• Convenient maintenance operation

Helping restaurants reduce maintenance workload.

Project Benefits

After installation, the system successfully helped the basement restaurant achieve:

✔ Reliable wastewater discharge from B2 kitchen
✔ Effective grease management
✔ Reduced risk of sewer pipe blockage
✔ Improved kitchen environment
✔ More compliant wastewater discharge

Typical Applications

This type of grease separation and lifting system is widely used in:

• Basement restaurants

• Shopping mall food courts

• Hotel kitchens

• Catering facilities

• Commercial complexes

• Underground food service areas

Professional wastewater solutions make underground commercial kitchens cleaner, safer, and more reliable.
