Gravity grease traps, also called “gravity grease interceptors” or “GGI’s,” are the most common type and are typically installed underground. These traps rely on the force of gravity to separate FOG from wastewater.Gravity grease interceptors are often made out of concrete but can be made out of steel, fiberglass, or plastic. They come in various sizes to accommodate different flow rates and are ideal for restaurants, cafeterias, and other food service establishments.Government regulations require them to be pumped out whenever the percentage of grease reaches 25%. Because they are placed in small locations, GGIs are rarely practicable for kitchens that produce modest amounts of fats and oils.

As wastewater flows through the grease trap, the FOG cools and solidifies, separating from the water. The trapped grease accumulates in the web while the treated wastewater continues its journey to the sewer system or a wastewater treatment plant.

For DTV installations, most local plumbing codes will require the installation of a check valve or backflow preventer to isolate the drain line from the potable water. A water hammer arrestor must be installed between the DTV and the check valve/backflow preventer if a check valve or backflow preventer is used. Failure to do so may cause permanent damage to the DTV and void the warranty.

To drain the backflow prevention assembly for protection against freezing, use the following procedures: 1. Turn off the main shut-off valve (A) which provides.

ThermOmegaTech offers an optional water hammer arrestor and backflow preventers to make life easier. Contact us or your local representative for more information on these products.

The DTV drain tempering valve is a self-operating drain cooler used in applications where a high-temperature discharge flow to a drain or sewer must be tempered with cold water. The thermostatic valve operates automatically to keep drain water within appropriate plumbing code limits and prevent PVC piping damage from over-temperature conditions.

Manual or “passive hydrochemical HGI” grease traps have been commonplace in restaurants and commercial kitchens for over a century. Typically made of stainless steel or plastic, these traps need to be cleaned regularly.HGIs utilize a combination of gravity and mechanical features for grease separation. They are equipped with a series of baffles and separators that enhance the FOG removal process, making them ideal for large-scale industrial operations.

The DTV provides a convenient, economical, and easy-to-use method of tempering hot effluent. Since this drain tempering water valve is open only when the effluent exceeds the specified set point temperature, it also conserves water by automatically turning off cold water when not needed.

This drain cooler water tempering device ensures water temperatures entering the sewer system do not exceeding 140°F, which can lead to failed inspections, fines, business interruptions, or injury and damage to personnel and equipment.

A steam condensate drain cooler is an essential component in many industrial processes where steam is utilized to heat a product or process. The DTV drain tempering valve, more specifically, is typically used in commercial dishwashers (warewashers), boiler blowdown drain lines, humidifiers, autoclaves, sterilizers, or any application that discharges scalding water to drains or sewers.

Automatic grease traps are known as “automatic grease removal units” or “AGRUs” among grease-trap insiders. This system is often located underneath a 3-compartment sink or floor of a kitchen. AGRU systems use mechanical means to separate grease from wastewater automatically. They are equipped with skimmers or augers that continuously remove and store the trapped grease for later disposal or recycling.AGRUs are more suitable for high-volume food establishments and offer convenience and efficiency in grease removal. The container can be emptied daily and made ready for collection by a hazardous waste disposal service regularly. A manual grease trap, on the other hand, must be emptied and cleaned by a specialist every two to four weeks.

As the hot effluent cools, the DTV automatically modulates to reduce the cold-water inlet flow. At about 10°F below the full open temperature, the cold-water inlet is fully closed again to conserve water.

In this comprehensive blog, we will answer what a grease trap is, how it works, the different types available, and the best practices for cleaning and maintenance.

Grease traps work on the principle of gravity and buoyancy. When wastewater enters the trap, it cools down, causing fats, oils, and grease to rise to the surface due to their lower density than water.The treated wastewater, which is relatively free of FOG, exits the grease trap through an outlet and continues its path to the sewer system. Meanwhile, solid food particles and other debris settle at the bottom of the trap, where they can be picked up and disposed of.

Hydronic circulating pumps move water through a closed system of pipes in heating applications or water recirculation systems.

If you don’t take good care of your grease traps or if you use strong degreasers, you might end up with bad smells, blockages, and spills. These kitchen mishaps can seriously disrupt your business, potentially leading to a temporary closure and damaging your reputation. Here are some additional tips:

Maintenance of grease traps, whether manual or automatic, is critical. What might happen if a grease trap is not properly maintained? FOG can harden and begin to seep out. Furthermore, if the pipes downstream from the grease trap become clogged with FOG sludge, the grease trap may become overwhelmed. This will cause your trap to fill with effluent, forcing local sanitary officials to close your restaurant or establishment.This would cause a huge headache for you and your business. If you maintain a grease trap from the start, you won’t have to deal with issues later on. That is why it is important to know how to properly clean and maintain your grease trap to save you time and money, rather than wasting resources on extra hazardous waste cleanup.

The tempering water valve (DTV drain tempering valve) is installed into the drain line such that the hot effluent passes over the thermal actuator, which controls the cold-water inlet port. If the hot effluent is above the specified set point of the valve, the actuator senses the rising temperature and signals the DTV to open to allow the injection of cold water to temper down the discharge fluid before it reaches the drain.

A grease trap, also known as a grease interceptor or grease recovery device, is a plumbing fixture designed to intercept fats, oils, and grease (FOG) from commercial and industrial wastewater.
