Sewage grease traps are devices that prevent oils from entering sewage treatment plants and pipelines. The principle of operation is based on the separation of liquid and fat. This is facilitated by the specific gravity of sediments, which has a lower mass than water. Fat particles appear on the surface and are retained by traps designed for this. After that, already cleaned liquids fall into the sewer.
Views
Where are grease traps used for sewerage? For a restaurant, for example, this is an indispensable thing. They are also used for industrial type enterprises where there is a discharge of undissolved particles. The main purpose of the application is to protect the pipeline from deposits that can lead to breakage.
Devices are divided conditionally by:
- manufacturers;
- usage options;
- mounting method;
- materials used for making.
Modernseparators made of stainless steel, fiberglass and plastic. The latter option most often has a grease trap for sewerage from the dining room. This is due to many positives:
- The ability to create both standard devices and according to specific customer requirements (throughput, dimensions and shapes).
- Easy to operate. After installation, only periodic cleaning of deposits is required, which is carried out using improvised means.
- The plastic sewer grease trap device is great for cafes and restaurants with low throughput.
- Sustainability. The plastic used does not harm the environment and he alth.
- Long service life, up to 30 years.
Fiberglass grease traps
The choice of materials is determined by the main characteristics of the operation of the device. Industrial-type devices are made of fiberglass. This material is more resistant to the intense influence of a chemical aggressive environment. Such separators are installed both outdoors and indoors. The case is not exposed to various atmospheric phenomena. The devices have sufficient reliability, light weight and easy-to-clean surface.
Steel cages
Stainless steel sewage grease traps are rational to use in large enterprises, since the distinguishing feature of suchdevices is high cost. But the high cost is fully justified due to the presence of improved characteristics compared to other types.
The material has high anti-corrosion properties, making it possible to use both indoors and outdoors. At the same time, in the first case, the device looks like an addition to the surrounding interior.
Many cage manufacturers sell galvanized steel products. Such options do not have the advantages of stainless steel and cost much less.
Installation of grease traps for sewers
In the building, appliances are installed in a separate room, in the basement or under the sink at floor level or with a slight recess. In order to properly operate outdoor devices and prevent all sorts of problems, installation requires earthworks, concreting of a solid and even plane. The best option would be installation by professional craftsmen.
To increase the service life, additional elements are used, for example, sensors for the degree of accumulation of deposits.
The most difficult task is the cleansing, but due to the parameters of the system, it is rarely needed.
Before installation under the sink, accurate measurements of the space for placing the device are required. Taking into account the fact that cabinets and other types of furniture are used in this place, you need 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 than3-4 cm to ensure efficient operation and easy access during preventive and corrective maintenance.
Important details
Compliance with established fire safety regulations deserves special attention, among which there is a ban on installing the structure near equipment that is highly flammable.
After completion of all work, the finished unit is tested, which makes it possible to determine the location of a potential leak. At unreliable joints at the points of connection to the sewer system and the sink, the likelihood of leaks most often occurs. The sealing quality is improved by the use of sealing tapes and silicone-type grease. The device package includes fasteners, 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 installing the grease trapping unit.
Parameters
Sewage grease traps for a restaurant can have different performance and power. The performance index of household-type devices reaches 2 l / s. Industrial devices include other devices with increased characteristics.
There are several cleaning methods, it is worth highlighting the automatic and manual options:
- Manually cleaned separators will have to be looked after by yourself. Cleaning is carried out using special products to get rid of fat.
- Appliances cleaned by special machines or pumps. This type of device most often has automated functions that notify the time of the onset of maintenance work. Street grease traps for sewerage and an industrial grease trap with a high efficiency coefficient have such properties.
Can I do it myself?
To make a do-it-yourself sewer grease trap, you do not need special materials and knowledge. Sheet polypropylene is used as the main element, parts of the required size are cut out of it, welded and sealed with a heat gun.
Grease traps of own or factory production have their advantages and disadvantages. In any case, such a simple device requires proper care, so you can avoid the growth of deposits on the pipes and clogging the sink.
It is also possible to create a grease trap using a plastic finished box. Holes for installing pipes are formed in it, a partition is mounted inside, as well as holes for removing fat and ventilation equipment. Ensuring the tightness of each structural element is the main task in the manufacture, otherwise a flood may occur in the kitchen. Below is a diagram of a grease trap for sewage of the simplest type.
What do you needgrease traps
There is a large amount of fat fractions in wastewater from the food industry, catering establishments and residential buildings. Grease traps for sewerage are used to retain fatty elements that are in drains. The functions of such devices are as follows:
- Maintaining the compliance of the saturation of wastewater with fat fractions with the standards established by special sanitary requirements.
- Identification, collection and separation of fatty substances and oils for further processing. In this way it is possible to create a valuable raw material for technical purposes.
- Preventing mineral oil and grease from entering wastewater treatment facilities.
Taking into account the specifics of working production, discharges from some machine-building enterprises, food and canning industries, meat processing plants and canteens have a high level of saturation with oils and fats. Residential sewerage systems keep up with them and discharge a lot of domestic oily drains.
People who have an autonomous sewage system in a country house also have to deal with blockages in wastewater disposal. This is facilitated by the underestimation of the total amount of fatty substances entering the sewer and affecting the throughput characteristics of the pipeline.
Most common patterns
Grease trap PE-0, 5 of the "Standard" series is used for household needs and ensuring the operation of public catering facilities. Product bodymade of polypropylene, which increases its durability and quality. According to customer reviews, such a grease trap is convenient to use in a limited space. The ease of use of the equipment is increased due to the compact dimensions and versatility of use.
Grease trap PE-1, 0 series "Profi" is used for installation under the sink or in close proximity to it. It has a peak discharge in the range from 60 to 90 liters. Based on customer feedback, it is worth noting the removable restrictor for a uniform, controlled flow of incoming fluid. But not everyone is satisfied with the operation, in particular cleaning, since fat masses are removed from the structure only by the manual method.
Grease catcher "Termite 0, 5-1, 5" can be used to prevent clogging of sewers both in cafes and at home. The mass of the unit is 7 kg, and the height of the exit and entrance is 22 and 24 cm, respectively. Most buyers who chose this model noted the ease of installation and performance. Many have paid particular attention to the solid construction with quality fittings.
