Grease trap for sewer for restaurant: overview, schemes, description and reviews

Grease traps for sewerage are devices that prevent oil from entering treatment facilities and pipelines. The principle of working on the separation of liquid and fat is based. This contributes to the specific gravity of the deposits, which has a smaller mass than water. On the surface are fat particles and trapped by traps designed for this. After the already cleaned liquids get into the sewer.

Kinds

Where are grease traps used for sewage? For a restaurant, for example, it is an indispensable thing. They are also used for industrial enterprises where there is a discharge of undissolved particles. The main purpose of the application is to protect the pipeline from deposits, which can lead to breakage.

Devices are divided conditionally by:

• Manufacturers;
• Parameters of use;
• Method of installation;
• Used for the manufacture of materials.

Modern separators are made of stainless steel, fiberglass and plastic. The latter option is most often a grease trap for sewage from the dining room. This is caused by many positive aspects:

• The ability to create both standard devices and specific customer requirements (bandwidth, dimensions and shapes).
• Ease of operation. After installation, only periodic cleaning of sediments is required, which is carried out with the help of improvised means.
• The device of grease trap of sewage from plastic is perfectly suitable for cafes and restaurants with low capacity.
• Ecological compatibility. Used plastic does not harm the environment and health.
• Long service life, reaching 30 years.

Fiberglass Fibers

The choice of materials is determined by the main characteristics of the device operation. Made of fiberglass industrial device. This material is more resistant to the intense influence of chemical aggressive media. Such separators are installed both on the street and in the room itself. The case is not exposed to various atmospheric phenomena. The devices have sufficient reliability, low weight and easy-to-clean surface.

Steel separators

Grease traps for sewage from stainless steel are rationally used in large enterprises, since the distinguishing feature of such devices is high cost. But the high cost is justified due to the presence of improved characteristics in comparison with other types.

The material has high anti-corrosion properties, which makes it possible to use both indoors and outdoors. In the first case, the device looks like an addition to the surrounding interior.

Many companies that produce separators sell products from galvanized steel. These options do not have the advantages of stainless and cost much less.

Installation of grease trap for sewerage

In the building, the appliances are installed in a separate room, in a basement or under a sink at the floor level or with a slight depression. For the purpose of correct operation of street devices and prevention of all sorts of problems for installation, it is necessary to conduct earthworks, concreting hard and flat planes. The best option is to install professional masters.

To increase the service life, additional elements are used, for example sensors for the degree of deposit accumulation.

The most difficult task is purification, but thanks to the parameters of the system, it is rarely required.

Before the installation under the sink, precise measurements of the space required to locate the device are required. Taking into account the fact that cabinets and other types of furniture are used in this place, it is necessary to pay attention to the fact that between the walls of the furniture and the grease trap there was a free space of no more than 3-4 cm to ensure efficient operation and unhindered access during preventive and repair maintenance.

Important details

Special attention should be paid to the observance of the established fire safety rules, among which there is a ban on the installation of a structure near equipment that is characterized by a slight ignition.

After the completion of all the work, the complete unit is tested, so that it is possible to determine the location of the potential leak. On unreliable joints in the places of connection to the sewage system and washing, there is often a possibility of leaks. The sealing quality increases with the use of sealing tapes and silicone-type grease. The device includes hardware, fittings and other necessary parts, but in some cases they must be purchased separately. The documentation attached to the selected element contains all the necessary information for mounting the grease collection unit.

Options

The grease trap for sewerage for a restaurant can have different capacities and capacities. The indicator of productivity of devices of household type reaches up to 2 l / sec. The other devices that have increased characteristics belong to the industrial ones.

There are several methods of purification, it is worth highlighting the automatic and manual options:

• Separators with a manual type of cleaning will have to be monitored on their own. Purification is carried out with the help of special means for getting rid of fat.
• Instruments that are cleaned by special machines or pumps. This type of device most often has automated functions that notify about the time of onset of maintenance work. Such properties have street grease trap for sewerage and industrial grease trap with a large efficiency factor.

Can I do it myself?

To make a grease trap for sewerage by one's own hands, special materials and knowledge will not be required. The main element is a sheet of polypropylene, parts of the desired size are cut out from it, welded and sealed with a thermo gun.

Grease traps of own or factory production have their advantages and disadvantages. In any case, such a simple device requires proper maintenance, so you can avoid the buildup of deposits on the pipes and clogging of the sink.

It is also possible to create a grease cap when using a plastic finished box. It forms openings for the installation of nozzles, a partition wall is mounted inside, as well as holes for fat removal and ventilation equipment. Ensuring the integrity of each element of the structure is the main task in the manufacture, otherwise there may be a flood in the kitchen. Below is a diagram of the grease trap for the simplest type of sewage.

What are greens for?

In the sewage waters of the food industry, catering enterprises and apartment houses, a large number of fat fractions are present. Grease traps for sewage are used to detain fatty elements that are in drains. The functions of such devices are as follows:

• Maintaining the consistency of wastewater saturation with fat fractions to standards that are established by sanitary special requirements.
• Identification, collection and separation of fatty substances and oils for further processing. So it is possible to create a valuable raw material for technical purposes.
• Prevention of ingress of mineral oil and grease into the construction of treatment systems.

Taking into account the specifics of production, discharges from some machine-building enterprises, food and canning plants, from meat processing plants and canteens have a high level of saturation with oils and fats. The sewage systems of residential buildings do not lag behind them and produce a lot of household oily drains.

People who have an autonomous sewage system in a country house also have to contend with clogs when draining waste water. This is facilitated by an underestimation of the total amount of fatty substances that enter the sewage system and affects the throughput characteristics of the pipeline.

The most common models

The grease separator PE-0,5 of the "Standard" series is used for household needs and for the provision of catering services. The body of the product is made of polypropylene, which increases its durability and quality. According to buyers' reviews, it is convenient to use such a grease cap in a limited space. Convenience of equipment operation is increased due to compact dimensions and universality of use.

Fat collector PE-1,0 series "Profi" is used for installation under a sink or in close proximity to it. Has a peak discharge in the range of 60 to 90 liters. Based on customer feedback, it is worth noting the removable limiter for a uniform, controlled flow of incoming liquid. But not all are satisfied with the operation, in particular cleaning, since the fatty masses are removed from the structure only by hand.

Zhirolovka "Termite 0,5-1,5" can be used to prevent sewerage clogging both in cafes and in everyday life. The weight of the unit is 7 kg, and the height of the outlet and inlet is 22 and 24 cm, respectively. Most customers who chose this model noted ease of installation and performance. Many paid special attention to a reliable design with quality installation elements.
