Modern septic tanks are usually made of polyethylene. But this does not mean that there is no sewage treatment plant made of other materials. An excellent example is the concrete septic tank Favorit. It is suitable for areas with heaving and clay soil.
Reviews of advantages and disadvantages
Reinforced concrete septic tanks are very durable due to the base material. Installation can be carried out even in conditions where groundwater is located quite high. Cleaning and filtration processes occur in a cast monoblock. Unpleasant odors and extraneous noises, according to consumers, are completely absent.
Septic Favorit is non-volatile and airtight. For the winter, preservation of the device is not required. The design does not provide for a complex pipe system and the need for complete cleaning of the station so often that operation is problematic.
Such work will only be possible once every 3 years. As some homeowners emphasize, they clean once every five years. Negative situations can develop only with illiterate installation, as well as non-compliance with operating rules. Consumers emphasize that they are described in detail in the instructions.
Technical Specifications Reviews
To date, three varieties of treatment plants from the manufacturer “Favorite” are known. The main differences between them are:
- performance;
- weight;
- dimensions.
How many people can serve this or that model depends on these parameters. According to experts, the Favorit 2P installation has the following dimensions: 3x1.7x1.4 m. The weight of the equipment is 5.5 tons. The treatment plant is able to serve a house in which 12 people live at the same time. The unit processes 2 m 3 of sewage per day. The cost of a septic tank is 62,000 rubles.
After reading reviews about the Favorit septic tank, you can understand that it is also offered for sale in the Plus model. Its productivity is slightly less - 1.5 m 3 per day. Dimensions are 2.6x1.3x1.4 m. 8 people will be able to service the installation. The total weight of the structure is 4 tons. The degree of purification reaches 95%. You will have to pay 57,000 rubles for this installation. According to experts, at first glance this price may seem rather high, but it is justified, because the treatment plant is durable and does not require special care.
Reviews on the principle of work and design features
If you want to buy the Favorit septic tank, you should understand its design features. Experts emphasize that the body is made of reinforced concrete, and there is a bypass between the sections. The above models are almost no different from each other, including the principle of operation.
Systems consist of:
- deflector;
- sewer and technological hatches;
- pipes for biogas removal;
- lids and chambers made of reinforced concrete.
The cover is intended for system maintenance. The Favorit 2P septic tank, the dimensions of which were mentioned above, is characterized in that it additionally has a drainage pump in the design. The cleaning process is very simple. Domestic wastewater enters the first chamber. There is a delay in surfactants, films and fats. All this could subsequently form a crust. The harder elements settle at the bottom, and the effluents are clarified.
Through holes in the septum, water enters the anaerobic digestion zone. There is no oxygen in the second compartment, and fermentation takes place there. Organic molecules, according to customers, undergo a hydrolysis and cleavage step. The result is:
All this turns into carbon dioxide and methane. In the next step, an inert load is distributed on the surface. Over time, a biofilm is formed, which consists of microorganisms. The purified water in the discharge zone is discharged through the filter.
Reviews on the individual characteristics of the varieties of the Favorit treatment system
On sale you can find several varieties of the described treatment system:
- "Favorite".
- Favorite Plus.
- Favorite 2P.
The first type is made of concrete, which provides increased structural strength. Installation, according to customers, can be carried out with a high level of groundwater. The housing is completely sealed. Favorite Plus is a three-chamber reinforced concrete tank. The first and second compartments are combined by a two-section digester. The third chamber is filtering. It is designed to clean and discharge sewage. Buyers emphasize that Favorit Plus is best installed on sandy ground.
If you purchase Favorit 2P, you will become the owner of a four-chamber septic tank made of reinforced concrete. The first and second chambers are combined by a digester. The third chamber is a filtering one, while the 4th one is for collecting and discharging treated effluents. According to experts, “Favorit 2P” is best installed on loamy and clay soils.
Reviews about the features of installation
Owner reviews about the Favorit septic tank will allow you to understand also how to install the equipment. Technologies that use polyethylene and monolithic reinforced concrete structures do not differ much. Before starting the installation of the described installation, according to consumers, it is necessary to prepare a place on the site. To do this, dig a pit, the dimensions of which should be slightly larger compared to a septic tank.
The bottom is leveled, the formwork is arranged inside. According to home masters, for this it is better to use chipboard. When pouring concrete, it is better to add reinforcing elements to it. At the next stage, it will be necessary to place the treatment plant on the channels. It is important to install shields to form the border of the hatch. When installing the Favorit septic tank, you must install the ventilation and exhaust pipes in the next step. Next, concrete is poured. The mixture is left to dry for two days.
Reviews about the features of operation
Use a treatment system in compliance with the manufacturer's requirements. The device should not be overloaded by more than 20% of the norm. Throw into the septic tank should not:
- washing solutions;
- construction garbage;
- solvents;
- acids;
- filters.
Septic tank service
Maintenance of the septic tank consists in checking the filling of the sump with sedimentary substances. The design must be checked for damage. Every month, the state of the filtering field is checked . It is important to make sure that its performance is maintained. Every year, the septic tank is cleaned of sediment. If such manipulations are regularly performed, then this will become the key to the effective functioning of the system.
The cleaning of the Favorit Plus septic tank consists in pumping out insoluble heavy fractions from the chambers using a cesspool machine. There is no need to come close to the outlet openings. Pumps will cope with the task from a distance of up to 160 m. If the organization uses special hoses, then this parameter increases to half a kilometer. The integrity of the filtration field is not violated, as well as its durability and functionality.
Finally
The cleaning operation includes pumping out insoluble deposits, cleaning the septic tank and erosion of the silty deposits. If necessary, you can disinfect the Favorit septic tank with reagents. This increases the cleaning efficiency and extends the service life.
