If you are interested in deep biological treatment stations, then as an alternative solution, you can consider the Aspen septic tank, which is a patented structure. It is intended for the treatment of domestic wastewater and is excellent for the climatic conditions of Russia, thanks to which the system has gained recognition and wide distribution.
Such equipment can be installed in gardening and summer cottages and on the territory of suburban housing. This decision will be a way out of the situation when it is necessary to solve the problem of waste and waste disposal. "Aspen" is able to clean the drains by 98%, which will provide the owners with the usual urban amenities and comfort. You can install the system on 2 private houses, which will save space on the territory and reduce costs.
Working principle
Septic tank "Aspen" works on the principle ofcombination of biological and mechanical wastewater treatment. The internal sewerage system is connected to a pipe through which drains enter the first chamber by gravity. Under the influence of gravitational force, heavy elements from polluted waters settle at the bottom of the installation, where they form activated sludge.
All contained films, fats and light impurities float up, and after a while a crust forms, which can be disposed of using a technical hatch. Activated sludge contains anaerobic bacteria that recycle solid waste.
The septic tank "Aspen" has a loading chamber, after cleaning the drains in it, the clarified water enters the settling chamber through overflows, from where sewage is sent to the biological filter. Inside this chamber, the third in a row, there are biofiltration films where artificially grown bacteria begin their work. The period of their growth lasts 3 weeks, in just two days the water will be purified thanks to them by 98%.
The described processes proceed with the formation of heat and gases that exit through the air. Behind the biological treatment chamber, water is directed to the infiltrator, which is a well or drainage field. The purified liquid can be disposed of in the soil or used for technical needs on the site.
Specifications
Septic tank "Aspen" is a non-volatile system, which consists of a reinforced concrete body. This provides reliability. The design is very simple, its service life reaches 50 years. Realizeinstallation is possible on soils with a high level of groundwater. Purification systems of this type have a low cost. You can use them all year round.
Osina is very easy to care for. There is no need to control the cleaning process. The operation of the equipment is not accompanied by the release of unpleasant odors. The system is able to withstand significant overloads that can occur when large amounts of water are discharged.
The principle of operation of the Aspen septic tank was described above. However, this is not the only thing the consumer should know. It is also important to familiarize yourself with the weaknesses. Among them, impressive weight and dimensions should be highlighted, which entails additional installation costs, the impossibility of transporting the system on your own and the need to involve special equipment.
The cleaning principle is based on a drip filter and a digester. The design provides for the presence of two chambers, which are enclosed in a single reinforced concrete case. Installation is carried out on a pillow of sand and gravel. Backfilling is done with a dry cement-sand mixture. Wastewater is forcibly discharged, they are pumped into the filter well.
By studying the characteristics of the Aspen septic tank, you can understand that it provides for the need to pump out once every three years. You can choose a system taking into account the volume of drained effluents. A design for 1000 liters will cost 65,000 rubles. If the first value increases to 2000 liters, then the price becomes equal to 95,000 rubles. When purchasing a septic tank with a volume of 3,000 liters, you will have to pay 120,000 rubles.
Some technicalcharacteristics of different models
Before you choose the Aspen septic tank for giving, you must understand the types of such equipment. The Osina-1 model, which is a universal treatment plant, is presented for sale. It is designed for 6 residents. Daily cleaning will amount to a cubic meter of wastewater.
"Aspen-2" is designed for installation in a house where no more than 12 people live. Productivity reaches 2000 l per day. Osina-3 is a facility for collecting and mechanical-biological treatment of domestic wastewater in buildings and houses where up to 18 people live. Every day the system will be able to process 3000 liters of wastewater. The body is made of reinforced concrete. This system is non-volatile and needs to be pumped out every 3 years.
Installation
Installation and installation of the Aspen septic tank can be carried out by you yourself. Work must be carried out in accordance with sanitary norms and rules. A pit and trenches are dug under the system itself and sewer pipes, the latter must have a slope of 20 mm per meter. The walls of the excavation should have a slope between 20 and 30°, the final value will depend on the type of soil.
If the walls are crumbling, then it is necessary to install formwork from wooden boards. If you decide to install an Aspen septic tank, you should definitely study the instructions for its installation. After reviewing it, you will be able to understand that it is necessary to lay at the bottom of the pit and trenchesa leveling pad of sand up to 10 cm thick. This preparation is spilled with water, rammed and checked by level. From the house to the cleaning system, it is necessary to lay a pipeline with thermal insulation.
The crane at the next stage lowers the septic tank into the pit. After that, the pipeline should be connected to the inlet and outlet pipes. Joints are sealed with cement-sand mortar. The system must be supplemented with a ventilation pipe, which rises above the ground by 1 m. Its diameter will be 100 mm. The design should be supplemented with a deflector, a cast-iron hatch and typesetting rings.
Installation features
Insulation is laid on the top of the septic tank, as well as on the walls of the system. Installation of drainage and storage wells, as well as the filtration field is carried out before backfilling.
The choice of infiltrator will depend on the preferences of the owners, as well as the type of soil and the level of groundwater. Backfilling is carried out in layers, for this it is necessary to use sand, which is spilled with water and rammed. This will eliminate the deformation of the insulation.
Operating instructions
The operation of the Aspen septic tank provides for the maintenance of the system once every three years. These works involve cleaning the bottom of the chambers from silt. You can do it yourself using a modern drainage pump or a simple bucket. An alternative solution is to call a cesspool.
Self-cleaning is a rather dangerous process, because the skin and respiratory organs must be carefully protected. After each cleaning and a break in the operation of the septic tank, bioactivators should be added to it, which will allow the process of wastewater treatment to be resumed. The biofilter must also be periodically cleaned. The main part of the plaque is utilized, as well as the existing bacteria.
How to maintain properly
The autonomy of the Osina sewage treatment plant is an order of magnitude higher than the autonomy of other septic tanks. Pumping out the latter should be carried out once every six months. The autonomy of Aspen lies in the fact that it does not need such frequent cleaning. However, the system still needs maintenance. This is the comfort of using the equipment.
For proper maintenance, it is necessary to clear the earth from the service hatch cover, open it and place the drain hose of the feces pump inside. He must reach the bottom. You can replace it with a vacuum hose of a sewage machine. This will download the contents of the first two chambers.
Biofilter cleaning
After examining the photo of the Aspen septic tank, you will see what the biofilter consists of. During the maintenance of the system, it is necessary to replace the expanded clay in this part of the device. The fraction must correspond to the limit from 20 to 40 mm. Part of the bacterial activated sludge remains in the chambers, and the same bacteria should be placed in the biofilter. This is necessary so that they can again form their colonies there andrecycle sewage just as efficiently.
After replacing parts of the biofilter and pumping out the system, the lid is tightly closed and checked for leaks. The thermal insulation material is returned to its place. If it is damaged, then this area should be replaced with a new cover of insulation. At the final stage, everything is covered with a layer of earth, which is slightly compacted.
Safety measures
When pumping out the septic tank and replacing the biofilter, you must follow the safety rules. The master needs to work with gloves, and protect the respiratory organs with a mask. These precautions are necessary to prevent harmful microorganisms, gases and vapors from entering the body and on the skin. Clothing should cover the entire body. It is not recommended to work in a T-shirt and shorts.
In closing
The Aspen branded septic tank is a robust, reliable and very simple installation that can be used in residential properties that are not connected to a central sewerage system. There are usually no problems during the operation of this equipment.
Installation can be done by yourself. True, you will have to use the services of heavy equipment, because the body of the unit is made of reinforced concrete, which has an impressive weight. But this is an advantage in some cases: the system will not be pushed out when the soil heaves.
