Septic tank Unilos Astra 5

Septic tank Astra 5 is designed for a small country house. Suitable for owners of a one-story house whose owners live only in summer and spring. Of course, you can use a septic tank at home in which 3-5 people will constantly live, but the manufacturer says that such a design is most likely designed for seasonal use. Design options: Maximum number of people living in the house is up to 5 people; Up to 600 liters of water are processed per day - on average, a person uses about 200 liters of liquid per day; The size of the salvo discharge is up to 250 liters; Power consumption up to 40 W; Installed in any type of soil.

Advantages and disadvantages of a biorefinery station

When choosing a device for wastewater treatment, you need to take into account its performance - for example, the Unilos Astra 5 modification is suitable for serving a family of 5 people, and processes up to 1000 liters of liquid per day. A volley discharge of 250 liters ensures uninterrupted operation of the system while simultaneously using two bathrooms, a shower stall and a bathtub, a dishwasher and a washing machine.

The advantages of the model include:

• dense walls;
• no corrosion;
• high performance;
• small dimensions;
• quick installation;
• the ability to select the pipe insertion depth;
• a sewer truck is not needed to pump out sludge;
• Suitable for all types of soil.

Installation of Unilos Astra 5 does not require concrete work - the device is installed on a sand bed 150 mm thick.

Among the disadvantages, the parallelepiped shape can be noted: during pumping, a small amount of sludge can be retained in the corners of the body. If there are no residents for more than 2 months, the station must be mothballed.

Connection

The connection diagram for all septic tank models is the same. Order:

• Preparing the site. To do this, you need a pit; its dimensions depend on the parameters of the station itself. There should be no stones or rubble at the bottom of the pit. Filling the installation site with concrete is not necessary, but during the installation of the septic tank, it is advisable to arrange formwork.
• Make a layer of sand at the bottom of the pit, its thickness is 15-20 cm.
• Next, install the station. Depending on its size, special equipment may be needed.
• After installation, fill water up to the marks on the housing.
• Only after filling with water can the space between the walls of the pit and the station be filled with sand to the level of the incoming pipe.
• Connect the sewer pipe by cutting a hole in the receiving compartment; be sure to seal the joints.
• The final stage is connecting the cable and installing the compressor.
• The final filling, after which the lid and about 20 cm of the height of the body will remain on the surface.

Unilos Astra is a product developed by a domestic enterprise for the treatment of household wastewater.

Septic tank Unilos Astra is a new generation aeration station with a patented technology for the biological decomposition of wastewater up to 98%. Work that is based on biological processes. Nature purifies water in this way and why come up with something new if you just help a little and speed up the process thanks to aeration. These devices are designed specifically to clean wastewater where this is impossible due to the lack of a central sewerage system. Sometimes the central sewerage system can be located at such a remote distance that even a rough acquaintance with the cost of connecting to it convinces you that it is better to organize wastewater treatment yourself.

The absence of bad odors allows installations to be installed near buildings, and, if necessary, in basements.

Please note that you can order a Unilos Astra 5 septic tank from us with turnkey installation in installments of up to 6 months. with an initial payment of 10%, and on credit up to 36 months with an initial payment of 0 rubles.

How can a country septic tank survive the winter?

Many future buyers of the Astra septic tank are worried that during frosts the station will freeze and stop working. This will not happen if you use the sewer regularly. Moreover, the number of drains must correspond to the nominal number of residents for which the septic tank is designed.

Therefore, it is important to clearly determine before purchasing how many people will permanently live in the dacha/country house. If you buy a model with a reserve, then nothing good will come of this idea. But specialists from the company selling the equipment will definitely consult about this and warn you about the consequences.

Be sure to clean the septic tank before preparing your seasonal cottage for winter, following the manufacturer’s recommendations

In order for Unilos Astra to survive the winter safely, you need to:

• mothball the septic tank;
• insulate by building a box over the protruding part.

Conservation is carried out only in the case when the dacha is used only during the season, and with the onset of cold weather no one will live there.

If the sewer is used in winter, then nothing needs to be preserved or insulated - the station warms itself, receiving regular waste and doing its job

For conservation, it is necessary to perform a full service of the equipment, cleaning all components and pumping out part of the activated sludge. Then place 5-liter eggplants half filled with sand into each compartment. This is necessary so that when freezing, the water in the container does not crush the walls.

A box over the lid of the septic tank will help it survive the winter safely. After all, it will not be used - the bacteria will not need oxygen

At a station disconnected from electricity, you need to remove the compressor and place it indoors. The part of the septic tank protruding above the soil level is insulated from above. To do this, construct a box on top of the container from penoplex or other insulation.

You can cover the box with plastic film to prevent the material from deteriorating under the influence of negative environmental factors.

If you install the septic tank correctly and follow the maintenance standards in winter, there will be no problems with its operation in cold weather.

Sewage installation

After preparing the pit, the station is lowered on cables to the bottom of the pit. Simultaneously with the septic tank being sprinkled with sand, water is supplied inside the system, which prevents deformation of the body due to soil pressure. After backfilling and filling the system, pipes are connected to the body. Welding is carried out with a hot air gun. Electrics are supplied to the control unit through sealed seals. The cable from the septic tank to the house is laid in HDPE corrugation.

Construction of a septic tank Unilos Astra 5

Unilos Astra is an underground polypropylene monoblock with a wall thickness of 20mm and a bottom thickness of 80mm. Inside, the septic tank is divided into four chambers: the receiving chamber is the largest chamber into which wastewater enters; here the natural process of sedimentation of particles takes place, whose density is higher than the density of water; aeration tank (a special aerator is installed in it, wastewater is saturated with oxygen and purified when interacting with sludge, an oxidation process occurs that allows a number of organic contaminants to be broken down and removed from the water); sludge stabilizer (waste sludge accumulates in this section and accumulates over time at the bottom of the tank); secondary settling tank (the water is additionally settled and discharged cleanly outside).

The waste that accumulates as a result of wastewater treatment can be removed using built-in pumps (which anyone can master). You can also connect additional drainage pumps to the installation - then the cleaning process will become even easier!

Service Unilos Astra

Once every 3 months: – removal of sludge from the settling tank using a standard pump with a plug; – cleaning the main raw water pump and the coarse fraction filter; – cleaning the walls of the secondary settling tank; – cleaning compressor filters.

Once every 6 months: – remove sludge from the sump using a drainage pump (if sludge has not been removed using a standard pump after 3 months). Untimely cleaning of activated sludge leads to disruption of the station. – cleaning the hair catcher in the aeration tank.

Once every 5 years - clean the equalization tank and aeration tank from stabilized sediment.

Once every 10 years - replacement of aeration elements. It is necessary from time to time to check the correct operation of the equipment visually with the lid open. During service, it is necessary to clean the walls of the secondary settling tank from the layer of deposited sludge.

Operation and Maintenance

The activated sludge produced as a result of biological decomposition processes can be used as a fertilizer. To clean the septic tank, you do not need a sewer truck; the sludge is pumped out with the pump that is included in the package, but it is faster to do this with a drainage pump.

Replacement of the solenoid valve, aerator, compressor membranes and the compressor itself may be necessary after 7 years of operation. Pumping out sludge and cleaning the air pump must be done at least 2 times a year. The hair trap is cleaned every six months.

Preservation of Unilos Astra for the winter

This event is carried out under the condition that there is no wastewater entering the station for a period of more than 3 months, and in this case the station operates seasonally.

When “preserving” it is necessary:

• Disconnect the compressor from the power supply, remove it from the station (store in a warm, dry place)
• Disconnect the station from the power supply
• Evacuate the sludge stabilizer chamber completely. Fill the sludge stabilizer with clean water to a level of 1.5 m from the bottom
• Pump out excess activated sludge from the aeration tank to a level of 1.4 m from the bottom. Add clean water to the receiving chamber to a level of 1.5 m from the bottom.
• Place 1-2 plastic bottles (volume 2 liters or 5 liters) filled with sand 50% into each chamber of the station.
• Insulate the station cover with insulation that does not absorb moisture (at least 50mm thick)
• Cover the perimeter of the station with film. The film must be secured.

Appearance of local autonomous sewage systems Unilos Astra

• The cover of the Unilos Astra station is located on the surface of the earth, which makes maintenance of the station quite simple, and the flow of oxygen into the compressor compartment is free. And the septic tank body itself is located underground and does not deteriorate the appearance of the suburban area.
• The entire system of deep biological wastewater treatment is housed in a single housing, thanks to which the design of the septic tank is compact and heat loss is reduced.
• The housing of the Unilos Astra station is made of polypropylene. This is an environmentally friendly material that is not susceptible to corrosion, which ensures high reliability and durability of the structure.
• The septic tank is completely sealed thanks to a unique welding technology, which also increases mechanical strength.
• Thanks to the small overall dimensions of the station and mounting loops, transporting and installing the septic tank is easy and convenient.
• Wastewater treated in a septic tank can be discharged directly into the ground, ravine or storage well, and if the septic tank has a forced discharge, then into a drainage ditch.
• Since the station body has stiffening ribs and is made of polypropylene, installation of the septic tank can be carried out without prior concreting

Pros and cons of treatment design

Any equipment has its positive and negative sides. It copes with some problems perfectly, but in others there are obvious shortcomings of the manufacturer. Strengths and weaknesses must be assessed at the stage of choosing a septic tank for your home or cottage.

Let us dwell in more detail on the advantages and disadvantages of the popular septic tank Unilos Astra. It is this question that helps many doubting homeowners make the final decision about purchasing an aeration station.

The septic tank fits perfectly into almost any local area without attracting undue attention

Advantages of this cleaning station

Sewage equipment for home use has obvious advantages.

Firstly , a high level of wastewater treatment. Its rate in Unilos Astra reaches about 98%. This means that purified water is absolutely safe - it can be used for watering flower beds and beds. It has the smell of clean river water.

This technical water is used to fill household reservoirs without consequences and dump them into a pond located not far from the house. It does not pose any hidden danger, so there is no need to worry about the deterioration of the ecological state of the environment.

The septic tank can be placed next to a reservoir and the purified water can be discharged into it - this will not harm the reservoir or the environment as a whole.

Secondly , the silent operation of the station itself and the absence of unpleasant odors nearby. This feature allows you to install the equipment next to a living room, bathhouse, or sauna.

Its work processes will not interfere with the usual rhythm of life of each of the family members living in the house. You don’t have to look for a place further away on the site or somewhere on the street, out of sight.

Thirdly , activated sludge removed from the compartment during maintenance can be sent to a compost heap or immediately used as ready-made organic matter for feeding shrubs, trees and other plants. This is a free fertilizer and completely safe.

Fourthly , there is a wide variety of model range of septic tanks for a summer house or country house Unilos Astra. You can choose an option that perfectly suits the needs of a particular owner. Moreover, both for a small family of 3 people, and for a large number of residents - 7-15 people.

When choosing a septic tank for your dacha, it is better to seek advice from specialists. After all, you can buy a much larger volume yourself, which will not be fully used

Selecting the right model is simple - the number in its name directly indicates which family the station is designed for. For example, Astra 5 involves servicing five people permanently residing in the house, and Astra 8 - eight people, respectively.

This means that the equipment will cope with the function of cleaning the wastewater of such a number of residents.

Depending on the needs of the consumer, there are models capable of treating wastewater from an entire holiday village of 100-150 people

Fifthly , the station has very compact dimensions.

The model range is presented in three modifications:

• Standard;
• Midi;
• Long.

Depending on the characteristics of the soil in which installation is planned, the appropriate option is selected. If no problems with excavation work are foreseen, then you can choose the Long . This equipment will be slightly longer than the Midi and even longer than the standard type.

Regardless of the modification, the station takes up very little space. Thanks to its dimensions, it can be placed anywhere. The main thing is that the owners feel comfortable

Sixth , ease of installation and maintenance of Unilos Astra. To install it, you don’t need heavy and bulky equipment that can destroy all the vegetation in the local area.

For maintenance, you also don’t have to call a sewer truck and spend extra money on it. Both installation and further maintenance can be done independently.

Seventh , the unit is made of durable and wear-resistant material. Polypropylene walls 2 cm thick withstand well the external influence of groundwater and the internal movement of wastewater. The equipment is reliable and can last at least 50 years.

Eighth , aeration equipment does not require intervention in its operation. It cleans the drains on its own, producing new bacteria during its operation. There is no need to buy special products or introduce new microorganisms into the system, provided you permanently live in a country house/house.

The septic tank is self-sufficient - it does not require intervention in the work, there is no need to pour or add anything into the container to improve the processing process

Ninth , the operating temperature inside the compressor is maintained at any time of the year. This feature allows you to use the compact sewer all 12 months. The main thing is that the bacteria do not starve without food and oxygen. They can withstand even a 4-6 hour absence of electricity without compromising the work process.

Tenth , laconic and stylish appearance. The station cover has compact dimensions and the ability to fit into the topography of the local area. It protrudes only 15-20 cm above the level of the soil cover and does not draw attention to itself in any way.

If desired, you can skillfully decorate the cover of the sewer equipment. After all, access to it is needed once every 3-4 months

The main disadvantages of a septic tank

In addition to many advantages, septic equipment has its disadvantages.

№1.

Dependence on electricity. If Unilos Astra can withstand several hour-long interruptions in its supply, then a day or two without electricity will destroy the bacteria. Considering this feature, you should take care of a backup autonomous power supply.

Although every homeowner living in an area with constant problems with the supply of electricity is concerned about the presence of a powerful generator. After all, for a comfortable existence it is necessary to ensure the operation of the refrigerator, TV, air conditioner and other appliances.

№2.

The need to periodically inspect and maintain equipment within the time limits specified in the instructions for using a specific Astra model. It also states what needs to be done and how often.

If desired, you can enter into an agreement with the company for service. Specially trained people will come and promptly carry out all procedures.

Maintenance is not so scary for summer residents and residents of suburban real estate. After all, in your own home, compared to an apartment, there are quite enough worries

№3.

From time to time you will have to buy filters, tubes, aerators, a pump and other components for the sewerage station. Each spare part has its own service life. This information is included in the instructions for use.

№4. Compliance with equipment operating rules. Thus, you should not flush rotten vegetables down the drain, pour out caustic chemicals in large quantities, dump construction waste, or oily substances of a technical nature.

Although, the station is able to cope with weekly cleaning of plumbing with tile detergents, laundry and dishwasher drains. The main thing is not to do it all in one day. It is better to distribute washing and cleaning on different days to reduce the load from harmful substances.

№5. In areas with a harsh climate, you will need to take care of additional hydro- and thermal insulation of certain elements of the sewer installation. This also applies to insulation in preparation for winter.

№6. Installation of equipment will require certain efforts and skills. But it is possible to cope with it on your own. And if desired, use the services of the organization from which Unilos Astra is purchased. It is also not recommended to install it at sub-zero temperatures.

№7. High cost of treatment station. Although, if you consider that its service life is 50 years, then the entire amount can be safely divided by this figure.

Thanks to the domestic manufacturer and product orientation towards the domestic market, climatic conditions and the needs of homeowners were taken into account

Having considered the main advantages and negative characteristics of Unilos Astra, you can get a general idea of ​​septic equipment.

The price-quality ratio is the most favorable when compared with foreign analogues. For a very affordable price, the consumer receives a high-quality product that is ready to last for half a century.

The quality of the equipment and the ease of its maintenance are directly confirmed by the positive reviews of many owners. The owners, having installed a septic tank at their dacha or in a country house, have already managed to test it in action, and also adapt to its features.
