Domestic Grease Traps for Sewer Systems

ZIKO supplies domestic and industrial grease traps for sewer systems of various types. The company’s specialists design, develop, and install turnkey water treatment solutions. ZIKO also offers, at competitive prices, a wide range of water filters, reverse osmosis membranes, systems, and equipment for effective treatment of wastewater and drinking water.

Purpose of a Domestic Grease Trap

A compact under-sink grease trap removes oily and greasy impurities from water used for dishwashing and other household needs. This reduces the negative impact of fats on metal sewer pipes and helps prevent pipeline blockages. A domestic grease trap converts household wastewater into technically treated water that is safe for both the environment and sewer systems.

Advantages of an Under-Sink Kitchen Grease Separator

In addition to affordability, domestic kitchen grease traps offer several advantages:

• wastewater purified from grease particles does not clog sewer systems;
• high-quality manufacturing materials provide corrosion resistance;
• sealed lids prevent the spread of unpleasant odors;
• simple design allows for easy and low-cost installation and connection.

Grease Trap Design

A domestic kitchen grease trap consists of the following structural components:

• a housing made of corrosion-resistant material with inlet and outlet connections;
• one, two, or three internal baffles that divide the grease trap into several chambers and slow down the water flow;
• a sealed lid with a rubber gasket, which prevents the spread of unpleasant odors resulting from the decomposition of grease particles inside the separator.

Operating Principle of Grease Traps

Domestic grease traps for sewer systems operate according to the following principle:

• Contaminated water from the sink enters the first chamber of the separator through the inlet connection. During sedimentation, grease impurities separate from the water and float to the surface.
• At the next stage, grease particles accumulated in the first chamber settle at the bottom of a dedicated tray, where they are retained.
• The water then flows through a lower connection into the second chamber of the separator, where final separation of grease residues not removed in the first chamber takes place.
• At the final stage, the treated water is discharged from the grease trap through the outlet connection into the sewer system.

During wastewater treatment, undissolved particles accumulate in the first chamber of the domestic grease trap; therefore, the separator requires regular cleaning and washing.

Classification and Materials of Grease Traps

All domestic grease traps for sewer systems operate on the same principle. However, models may differ in installation method. Some grease traps are installed horizontally, while others are designed for vertical installation. The choice depends on the layout and direction of the sewer pipelines.

Under-sink domestic grease traps are manufactured from corrosion-resistant materials, including:

• Metal. Grease traps made of stainless steel or aluminum are efficient and durable but relatively expensive. Metal separators are highly reliable, long-lasting, and easy to clean.
• Fiberglass. Fiberglass under-sink grease traps are strong and resistant to chemical exposure. Such units can be installed outdoors or buried underground.
• Polyethylene and polypropylene. Grease traps made from these materials are affordable, lightweight, and easy to maintain.

Criteria for Selecting Grease Traps for Sewer Systems

Before selecting and purchasing a grease trap, it is necessary to determine a number of key parameters the unit must meet:

• Available space under the sink. Clearance must be provided above and on the sides of the separator for pipe connection and lid removal.
• Number of sinks. When calculating grease trap capacity, the total wastewater volume from all active taps must be taken into account.
• Diameter of sewer pipes and inlet/outlet connections. These must match to allow installation without special adapters.
• Wastewater composition. If the effluent contains a high concentration of solid particles, a grease trap with multiple internal baffles is recommended.
• Sink volume. In some cases, rapid discharge of a fully filled sink is required. The grease trap documentation must specify the maximum volume of water that can be supplied to the unit at one time.
• Material of manufacture. If the separator is installed in a visible location, a stainless steel grease trap is preferable. For under-sink installation, a cost-effective plastic model is usually sufficient.
