Prevention of blockages in the local sewer system should be carried out at least once a quarter
Internal structure of the structure
Unilos Astra 5 station is divided into 4 reservoirs. Initially, all wastewater is collected in the receiving compartment, where heavy fractions are separated. Next, the liquid enters the aeration tank, where it is saturated with oxygen, and the Unilos Astra 5 valve begins to operate. This compartment contains activated sludge, which is one of the components for creating colonies of special microorganisms that destroy all waste.
When it enters the third tank, sludge is separated, part of which is returned to the aeration chamber, and part is pumped into the last compartment, from where it must be periodically pumped out. Maintenance of the Unilos Astra 5 septic tank should be carried out regularly.
Purpose and operating instructions for autonomous sewerage
The Unilos deep biological treatment station is an alternative to connecting to a public sewer. Independent discharge of untreated water onto the ground causes serious harm to the environment and is punishable to the fullest extent of the law.
Installation of the system must be carried out in full compliance with all required SNIPs, which regulate the level of installation and other nuances. Before discussing the Unilos treatment plant, you should pay attention to the types of septic tanks. Formally, they can be divided into three groups:
- Cumulative.
A slightly improved version of the classic cesspool. In this case, the container performs the functions of a receiver, accumulation and settling tank. Cleaning is carried out exclusively using a vacuum cleaner.
The system assumes the presence of an unpleasant odor, as well as high costs for the constant removal of sewage equipment. This type is completely unsuitable for residential buildings, since the tank will often fill up and require emptying. At the same time, it is easy to install.
- With additional purification through soil.
The primary stage of purification is the separation of the liquid into fractions: water is discharged into one cavity, large contaminants into another. Next, the main stage of purification begins: the water is exposed to anaerobic bacteria. Methane is removed from organic matter through special ventilation outlets.
The presented system involves sewage disposal once a year. The disadvantages of this approach are the need to provide a large area for installation of equipment, limiting the types of working soil (a large percentage of clay is a contraindication), as well as its periodic filtration.
- With biological treatment.
The method is based on a combination of the best qualities of both approaches, combining them with modern technical solutions. The Unilos work scheme falls into this category:
- The waste mass is saturated with oxygen in order to increase the efficiency of aerobic bacteria.
- Next, the filtration process begins, followed by biological treatment (including the oxidation of water and its saturation with minerals). As a result of the implementation of processes, activated sludge is formed in the system (it is needed for biological filtration).
- Activated sludge is separated from water. *Part of the sludge that is unsuitable for biological filtration is sent to a separate tank.
The last stage is the removal (gravity or mechanical) of water from the system.
At the exit, the wastewater receives a purification degree of 98%. Thus, they can be dumped even within protected areas.
At the same time, maintenance and cleaning of septic tanks of the Astra model range seem quite simple.
Main advantages of the model
According to the information specified in the operating instructions from the manufacturer, servicing Unilos Astra 5 should not cause difficulties. Turnkey installation of Unilos Astra 5 is completed within one day. The process is accelerated by eliminating the need for concrete work. The main advantages of the model include:

The lineup
A septic tank for a cottage or country house Unilos is an excellent solution, but it is important to choose the right model so that it provides effective drainage of wastewater depending on the number of permanent residents.
Unilos 3
Septic tank Astra 3 is the most compact representative in the LOS (local treatment plant) line. It is perfect for a summer house, or for a family of 3 people. Septic tank Unilos Astra 3 has small dimensions: length – 1.12 m, width – 0.82 m, height – 2.03 m; weighs 120 kg. The installation contains all the necessary elements that help clean wastewater efficiently and quickly. The Astra 3 type treatment plant processes up to 600 liters per day. The installation can be installed if the depth of laying sewer pipes from the house does not exceed 60 cm.
The body of Astra septic tank 3 is made of durable plastic, which is absolutely environmentally friendly and, very importantly, sealed material. Due to the increased strength, it is possible to save on installation - there is no need to fill the pit with concrete. The Astra 3 sewer system will withstand a salvo (one-time) discharge of up to 150 liters.
Advice! Since such an installation is most often installed for dachas, it is advisable to insulate it. Astra 3 septic tank must be preserved for the winter if it will not be used.
Unilos 4
The Astra 4 septic tank is designed for use by 4 users. It is somewhat more powerful than the previous type and larger in size. Specifications:
- Length – 1.12 m.
- Width – 0.94 m.
- Height – 2.28 m.
- Weight – 120 kg.
The daily capacity of such an installation is 800 liters, and the salvo discharge is 180 liters. The pipes must have the same depth - 60 cm.
Unilos 5
Astra 5 station is the most popular for domestic use, since the ability to drain wastewater when there are 5 people living in a house is the optimal solution for the average family. The installation of the popular Astra 5 septic tank can be carried out for the maintenance of a country house or cottage. Its wastewater processing capacity is 1 m³ per day. In this setting you can reset:
- Drains from the kitchen.
- Toilet paper.
- Drains from the bathroom, shower, washing machine.
- There is a small amount of drainage after cleaning the toilet. Just a small one, because this process often uses aggressive chemicals that can destroy bacteria.
Various types of septic tank Astra 5
Astra 5 septic tank is not designed to discharge:
- Compounds that cannot be biodegraded.
- Construction waste.
- Aggressive chemicals, acids, oils.
- Rotten food.
- Animal fur.
- Medicines
- Chlorine-containing substances.
Note! Similar recommendations can be seen not only for Astra 5, but also in the instructions for other similar installations of different sizes.
You can install an autonomous sewage system Astra Unilos 5, which provides forced drainage of wastewater. Its configuration differs from the basic one due to the presence of a pump for pumping out wastewater. In this case, during installation, you will also have to equip a drainage well, where liquid treated wastewater is discharged.
Unilos 6, 8
Septic tanks with the ability to serve 6 and 8 people are not as popular as the previous type. Characteristics of septic tank Astra 6:
- Length – 1.12 m.
- Width – 1.15 m.
- Height – 2.36 m.
- Weight – 210 kg.
- Productivity – 1 m³.

- Length – 1.5 m.
- Width – 1.16 m.
- Height – 2.36 m.
- Weight – 320 kg.
- Productivity – 1 m³.
- The maximum salvo discharge that the Astra 8 septic tank can withstand is 350 l.
In the Astra 8 septic tank model line there are variations that have similar technical characteristics, but with deeper pipe connections. If for the standard version it is 60 cm, then for “midi” and “long” it is more than 80 cm.
Unilos 10
Unilos Astra 10 is a model that is the most productive for use in domestic conditions. The station is quite large: length – 2 m, width – 1.16 m, height – 2.36 m. It weighs 355 kg. Septic tank Astra 10 has a capacity of 2 m³ per day, and a salvo discharge of up to 550 l.
Since the dimensions, and therefore the area of soil pressure, are larger, there are stiffening ribs that will prevent the compartments from deforming. Due to the high bandwidth, Unilos Astra 10 can be connected to:
- Kitchen drains.
- Drains from the bathroom, shower.
- Bathhouse, jacuzzi.
This installation can also be used to install an autonomous sewer system for small cafes and restaurants, if it is not possible to tie into a centralized system.
Other models
Unilos Astra is also offered in other models. The number of people served and the disposal of wastewater from their life varies from 3 to 150. The most massive and productive installations can be used for entire residential areas, hotels and other commercial purposes.
Maintenance Recommendations
Based on the data provided in the instructions, cleaning Unilos Astra 5 from sludge is required once every 6 months. This period may vary depending on the intensity of operation of the station. Every five years it is necessary to seek help from specialists in order to completely clean the aeration tank and other tanks. After 10 years the aerator will need to be replaced. provides all types of warranty services, and carries out effective cleaning of Unilos Astra 5 if necessary. Any Unilos Astra 5 spare parts are available for sale.

However, it is quite possible that this situation was caused by incorrect selection of the installation’s power or violation of the rules of its operation.
How is installation carried out?
A detailed diagram of the turnkey installation of the Unilos Astra 5 septic tank is described in the instructions. The main requirement is the need to minimize sudden changes in height when laying the pipeline during the installation of the station. The length and width of the pit should be 50 centimeters greater than the dimensions of the septic tank. A sand cushion 15 centimeters thick is formed at the bottom of the pit. The station is lowered into the pit using special cables so that the housing is securely fixed in a vertical position. After this, the internal tanks are backfilled with water to eliminate possible malfunctions of the Unilos Astra 5 during commissioning. The electrical cable is laid along with the pipeline. The Unilos Astra 5 control unit is connected, the pipes are cut in and the joints are sealed.

The algorithm for pumping out silt deposits is simple; you will need:
- Turn off power to the compressor . Open the lid of the septic tank and set the green button on the control unit to o. This should stop the system. Set the red and black buttons to o. Let the sludge settle for 15-20 minutes.
- Prepare the pump hose . It passes from the stabilizer directly into the receiving chamber. Remove it from the clip and use a screwdriver to loosen the plug. Now you can simply put it aside.
- Pump out the sludge . Unilos Astra septic tanks are equipped with a special pumping system. To start, set the green panel button to o. Don't forget to first lower the hose into the bucket where you plan to remove the sludge. As soon as the container is full, press the button until it reaches the o position. This will stop the draining process. Empty the bucket and repeat the procedure again until the tank is completely pumped out.
A signal about the completion of pumping out sludge will be a flow of liquid with a consistency similar to water.
After the procedure, plug the hose of the Unilos 5 or other septic tank and return it to its original place. The buttons on the panel should take the automatic mode position:
- Green – “1”.
- Red – “0”.
- Black – “0”.

How a septic tank works in winter, preservation for the winter.
Septic tank Astra in winter
To operate the septic tank Astra in the cold season, you only need to use it constantly. The operating temperature inside the device is maintained automatically. In this case, it is better to buy a device that exactly matches the number of people living. For those conditions when the septic tank will not be used during periods of cold weather (for example, at the dacha), it is necessary to properly preserve it and insulate it.
For conservation, you should take the following steps:
- carry out complete technical device maintenance.
- clean and rinse all its parts
- pump out some volume of sludge
- Place 5-liter canisters, approximately half filled with sand, in each of the sections. This is done so that frozen water does not damage the walls of the departments.
- the compressor must be removed and stored indoors
- insulate the part of the body located above the soil level with penoplex and cover it with film
In general, the device has a number of undoubted advantages and if you are willing to spend the necessary funds on its purchase and maintenance, it is well suited for servicing a private cottage or summer house.
Internal structure of the system: functions of compartments and principle of operation
Created on the principle of wastewater purification using aerobic microorganisms in a special chamber, the Astra septic tank consists of four chambers, which are located in a single external rigid housing.

The septic tank consists of four separate chambers combined into a single body
Receiver
From the house, liquid waste flows through the sewer pipe into a storage chamber, which is a waste receptacle. A hard waste filter is located in it and heavy particles settle to the bottom of the compartment in the sludge. In addition, dirty particles are crushed in the receiver using bubbling. That is, using active mixing. Using an airlift, purified water and crushed dirty particles are pumped from the next compartment, called the aeration tank. This happens when the compressor is turned on.
Aerotank
The main purification of water from dirt impurities occurs in the second compartment, where wastewater is pumped from the receiver. An aerator is installed in this chamber. When a new portion of dirty waste arrives, the compressor pumps external air through the aerator, saturating the substance with activated sludge in the compartment with oxygen and activating the proliferation of aerobic bacteria. The decomposition process occurs quickly, the water is purified and, through a hair cleaning system, enters the “pyramid” or secondary settling tank.
Secondary settling tank
The purified liquid enters the pyramidal chamber through the airlift recirculation system. No oxygen enters this compartment; no active processes occur here. As a result, the water settles and the sludge settles in the lower part of the secondary chamber. The design here is such that the sludge moves into the aeration tank.
Activated sludge is cleaned of the fat film using a special fat solvent, and the purified particles enter the main chamber for subsequent processing. The water, completely cleared of sludge, flows by gravity or is forced into the outlet pipe. If the liquid level in the sump drops, the recirculation process is activated using an airlift.
Water purification sump: installation and bacteria
The fourth chamber of the Unilos septic tank is also called sludge stabilizer. The excess settling sludge that accumulates in the aeration tank is moved through the airlift system to the last settling tank. In this chamber, the final purification of the remaining liquid occurs to the level of clarified water. Activated sludge, meanwhile, settles to the bottom and goes through a stabilization stage.
This product is already a ready-made fertilizer that the site owner can use to feed plants.
At the same time, during recycling, part of the water and activated sludge is pumped into the receiver, where it is mixed with large dirty particles and participates in their grinding and decomposition. The next time wastewater enters, the liquid level in the chamber rises and the purification process starts again.

Structure of a septic tank
Septic tank Volgar
Most recently, the Volgar-76 company introduced a new septic tank Volgar. It is modeled after the Astra, but has improvements. In particular, it has a cylindrical body made of monolithic polypropylene. This body is lighter than that of Astra, and the load is distributed evenly over it. There is only 1 weld on the body, and there are also lugs - bottom protrusions that take on the vertical pressure of the soil and protect the station from floating.
Before checking the Astra septic tank for leaks, it is tightened with clamps and only then filled with water so that the body does not deform. The Volgar septic tank and other cylindrical stations (BioDeka, Eurobion) are filled with water without screed and the body can withstand the pressure.
Bioseptic tank Astra building
The body of the Astra septic tank is made in the shape of a parallelepiped. It is made from integrally foamed polypropylene produced in the Czech Republic. Foamed polypropylene has three layers, with the middle layer being porous. When compared with homogeneous polypropylene, foam has better thermal insulation and almost the same strength. The sheet thickness is 15 mm, so the body can withstand ground pressure well. Mounting strips are needed not only to lower the station into the pit, but also to give the body additional rigidity.
It should be taken into account that the Astra body is manually welded with a hot air gun using a polypropylene rod from separate polypropylene sheets. Welds are the weak points of the structure. Note that the soil presses unevenly on a rectangular body and the likelihood of damage is higher. There are no lugs on the Astra's hull, although if the septic tank is filled with water, it will not float up.
Flaws
Despite many advantages, Astra septic tanks have a number of disadvantages.
- High cost of the cleaning system.
- Expensive maintenance.
- The need to annually replace the anaerobic bacteria pack for the storage tank.
- The need for additional insulation of the installation during installation.
- Repair of the Astra septic tank is expensive, due to the fact that it is impossible to do it yourself. Specialist intervention is required.
- During long-term operation, replacement of airlifts and internal tubes is necessary.
- In the event of a power outage, the installation cannot be used due to the risk of overflow.
Septic tank Unilos Astra is very popular among summer residents.
