How to choose the grease trap and mount it to the sewer

The drains inside the sewer pipes contain a large amount of contaminants, among which various oils and fats occupy the last place. These substances stick to the inner surface of the pipelines, reducing their diameter and reducing the throughput of the sewage system. Over time, fats can completely block the pipe. In addition, the fatty acids present in the substance provoke corrosion of the metal, destroying the elements of the pipeline. As a result, the sewage system quickly deteriorates. To prevent this, special devices have been developed - grease traps, the main function of which is to filter effluents from fats, oils and other polluting substances.

Grease trap principle

The grease trap is a filter that separates greasy dirt. At the heart of his work is the principle of gravity. Particles of oil and fat are much lighter than water, so they collect on the surface and fall into a special sump. Henceforth, contaminants are easily removed. Any grease trap consists of several elements:

  • The compartment where the fat is collected.
  • A flask consisting of several compartments for settling sewage.
  • Intake manifold.
  • Exhaust pipe connected to the sewer.
  • Airtight cap to prevent the spread of odors.

During the operation of the device, special enzymes are added to it, which break down the accumulated fat and increase the time interval between cleaning the device.

Using equipment provides several advantages:

  • No unpleasant odors arising from the breakdown of fats.
  • Easy maintenance and installation.
  • The tightness of the device, eliminating the possibility of foreign matter getting into it.
  • The ability to install additional devices, for example, a sensor for the accumulation of harmful substances.
  • Long term of operation.
  • Relative to other filters, the cost of the device is low.
Grease trap principle

The principle of operation of the grease trap is simple. Drains entering the equipment are separated. Oils and grease enter a special chamber and are subsequently removed

You can choose the right grease separator, consult its technical specifications, and purchase it at a good price from the TAUBER manufacturing company.

Choosing a good fat trap

There are several important criteria for choosing grease traps.

Aspect # 1 - Filter Installation Type

By type of installation, all devices are divided into two types: indoor and outdoor.On sale there are "mixed" models that can be mounted anywhere, but they are quite rare. Equipment for indoor use is notable for its low cost and ease of installation. Devices can be installed in different ways:

  • directly under the plumbing fixture;
  • in a room reserved for this purpose;
  • in the basement.

There are no fundamental differences in these methods. The difference is due to the usability of the devices and their dimensions. Outdoor equipment must be made of durable materials, as it must successfully resist ground pressure. As a rule, the throughput of such devices is greater than that of analogues intended for indoor use.

Grease trap

Plastic grease traps most often have a small capacity. They are intended for domestic purposes and are installed indoors

Accordingly, the cost will be slightly higher. Experts recommend installing additional devices for the correct operation of the device, for example, a sensor for the level of accumulation of fatty deposits. Installation of street grease trap is quite complicated. First, you will need to carry out earthwork, concreting the surface and only then you can proceed to installation. Many trust this work to specialized companies.

Aspect # 2 - instrument body material

Housings of modern filtering equipment are made of three materials. Plastic devices are most often installed indoors. They are characterized by:

  • Environmental friendliness. Plastic is safe for people living in the house and the environment.
  • Long service life, which reaches 30 years.
  • In addition to standard models, it is possible to manufacture the instrument housing for specific requirements.
  • Ease of maintenance, which can be carried out, literally, by improvised means.

Fiberglass grease traps are more durable and resistant to the possible effects of aggressive chemicals and adverse weather conditions. The devices are lightweight, reliable and, like plastic appliances, easily cleaned if necessary. Fiberglass equipment can be designed for indoor or outdoor installation. The strength of the material allows this.

Stainless steel filters are among the most expensive grease traps. They are distinguished by high performance, long life and excellent hygienic properties. Corrosion-resistant qualities of the device are also high. Devices can be installed outdoors or indoors. In the latter case, it will look very aesthetically pleasing, decorating the interior. Some manufacturers produce galvanized steel grease traps. The quality of such devices is much lower than that of stainless steel counterparts.

Aspect # 3 - Performance

The performance and power of grease traps vary significantly. Devices with a capacity of 0.1 l / s and up to 2 l / s are considered household. All equipment with greater productivity is considered industrial. Filtering devices also differ in the way they are cleaned. Allocate devices:

  • Manual cleaning. Most often these are grease traps for rooms, characterized by a small bandwidth. They should be under constant human control. Their cleaning is done manually using improvised means.
  • Mechanized cleansing. Mostly these are high performance industrial fat traps. Devices, as a rule, are equipped with sensors that indicate the need for cleaning. The procedure is carried out using specialized machines or pumps.

Unit Installation Technology

The installation procedure can be carried out in different ways. It depends on the type of appliance. Consider the two most common options.

Street type trap installation

The event is among the rather complex. Many prefer to entrust it to specialists. If you want to do everything yourself, you need to carry out such work:

  • Choose a place to mount the filter. When choosing, the layout of the personal plot and the possibility of carrying out any landscape work in the future are necessarily taken into account.
  • We determine the dimensions of the pit, which is necessary for the installation of equipment. Its depth should be such that the cover of the grease trap protrudes 3-4 cm above the surface of the earth, and a solid dump is present at the bottom of the pit.
  • Dig a hole. At the bottom of a mixture of cement and sand, we equip solid formwork. The amount of cement in the solution is determined by the type of soil. For loams and sandy soils, a mixture diluted 1: 5 will be enough. For more unstable soils, the amount of cement is increased.
  • We wait until the flooded base is completely dry. We put in place the body of the trap for fat and fix it to a solid base using anchor bolts.
  • We install plywood formwork around the device. This is to prevent soil shedding. If the equipment will be operated in a cold climate, it is covered by thermal insulation material. Styrofoam or mineral wool is quite suitable.
  • The outlet pipe of the device is connected to the drainage system. All joints are carefully treated with sealant.
  • The inlet pipe of the device is connected to the sewer pipe. The joint is smeared with sealant.
  • We fall asleep the free space between the body and the ground. Most often, the so-called backfill is used, that is, the soil previously selected from this place when digging a hole is poured into the opening.

Do not forget about the fun boner. It is necessary for the removal of excess gases from the sewer system. If it is assumed that the load on the drainage system will be large, it is best to install not one riser, but two.

 Grease trap cleaning

Street grease traps are most often cleaned using pumps or special equipment. A fat accumulation sensor installed inside the device warns of the need for a procedure

Mounting a fat trap indoors

Installing the grease trap under the sink is much easier than on the street. To do this, you need to follow these steps:

  • We determine the place for installation of the device. It should be an easily accessible hard and even surface, if possible in the immediate vicinity of a sink or dishwasher.
  • We set a trap for fat.
  • We output the outlet pipe to the sewer system. Be sure to install the rubber gasket that comes with the device at the connection site.
  • We connect the inlet pipe of the device to the outlet pipe of the sink or to the section of the pipeline where the washing equipment and the sink are connected. Do not forget about the special gasket.
  • We collect water in the grease trap and check its tightness. If everything is in order, we replace the instrument cover.

Grease trap - equipment necessary for the arrangement of the sewer system, designed to reduce the amount of oil and fat in wastewater. It is quite effective, even the simplest models reduce the fat content in drains by an average of 25%. Devices do not require complicated maintenance. It is only necessary not to forget about timely cleaning of the filter. Traps for fat make it possible to significantly reduce the risk of overgrowing from the inside and clogging of sewer pipes. For metal elements, the risk of corrosion is also reduced. A correctly selected and correctly installed device will become a reliable defender of the drainage system.
