Comfortable living in the country or in a country house is impossible without the organization of individual sewers. Not all villages have centralized networks for organizing amenities. In most cases, you have to take care of this yourself.

Here the septic tank “Unilos Astra” will come to the rescue - an excellent equipment that can perform the function of cleaning the waste products of the whole family for many years.

We will tell you in detail about the device and the principle of operation of the cleaner, identify its pros and cons, and also give practical recommendations for the operation and maintenance of the unit.

Device and principle of operation

In order for an individual sewage system to fulfill its duties, it is necessary to monitor it, timely service and replace worn parts. The service life of the Astra septic tank is 50 years. During this time, many components will have to be replaced.

The instructions for use indicate which components in what time frame to be changed. To avoid problems with the operability of equipment, you have to figure out what it consists of and how it works.

The basis for the development of the treatment plant “Astra” was LOS "Topas", therefore, many structural elements and principles of operation of the plants are very similar.

Unilos Astra is a capacity of a certain volume, the walls of which are made of polypropylene 2 cm thick. Its volume depends on the ability to serve the needs of a certain number of residents. These data are indicated directly in the name, for example, aster 5, aster 8, etc.

Place for installation of a septic tank
A convenient place should be selected for the installation of equipment, given that it will stand there for 50 years

The unit has a lid with a fungus through which air enters. It is insulated. The tank itself is equipped with stiffeners and is divided into 4 compartments. In each of them there is a separate process for wastewater treatment.

First, contaminated water enters the 1st compartment, where there is a filter for large fractions. Everything is upheld here. Then the effluents are pumped into the second compartment, where aerobic bacteria are taken for them, turning the waste into activated sludge.

Scheme of the septic tank Unilos Astra
The installation has an instrument compartment. Here is its smart part, which has a degree of protection IP 55, which will withstand splashing water (+)

In the third block, the older sludge settles to the bottom and settles, and the new one, floating in the upper part, returns for recycling back to the second compartment. In the fourth, additional purification of water and its withdrawal to the outside occurs. It is 98% clean and completely safe.

To ensure the operation of the septic tank, electricity is used. The equipment itself has a pump, pipes and tubes, a grease and hair trap, filters, a circulator and a recirculator.

Septic tank air tubes
Air tubes are recommended to be replaced every year and cleaned every 3 months. This will ensure the smooth operation of the system.

Bacteria needed for waste treatment do not need to be purchased separately. They, as a rule, originate themselves during operation. Moreover, it takes 2-3 weeks, or even a whole month, if the equipment serves the appropriate number of residents.

Sewage flows through a sewer pipe
When connecting the system, it is not necessary to fill in the bacteria inside. It is advisable not to throw anything directly into the septic tank - the waste must come through the sewer

If you wish, you can accelerate the nucleation of aerobes. To do this, bought special bacteria marked start. They are divorced in water, according to the instructions, and flushed into the toilet. In the future, you do not need to buy anything - Unilos Astra is self-sufficient equipment that provides itself with aerobes.

  • do everything yourself.

The essence of this process is washing filters, tubes and pipes, cleaning the walls of contaminants, pumping activated sludge from the sump. This is within the power of the owner of the homeowner, most importantly, carefully read the instructions.

Moreover, it is advisable to open the lid once a month and watch how the system works. There should be no unpleasant odors. If such a phenomenon is observed, then an error was made during installation.

This is possible when the owner himself carried out all the installation and connection work. Here, the best way is to invite experts who will point out errors and correct them.

Flushing the walls of the tank
Flushing the walls of the tank every time is not necessary. This can be done once every 6 months.

Once every 3 months should be cleaned:

  • mamut pump;
  • walls of the secondary sump;
  • blower filters.

Also, sludge should be removed from the sump. All components are well detachable and removable. This allows them to be washed without difficulty, and then put in place.

Cleaning hair catcher
Once every three months, the sewage system must be cleaned of sludge using a standard pump. Once every six months, it is necessary to pump out the sludge with a drainer and clean the hair trap

The equipment manufacturer recommends that every 5 years, the aerotank and surge tank be cleaned of stabilized sediment. The aeration elements themselves must be replaced every 10 years.

As for the replacement of individual elements, the compressor itself can last from 5 to 10 years, and it is advisable to change its membrane every 3 years.

How to cottage 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 the sewage system is regularly used.

№1. Dependence on electricity. If Unilos Astra is able to withstand several hours of interruptions with its supplies, then bacteria will kill a day or two without electricity. Given this feature, you should take care of a stand-alone autonomous power source.

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

№5. In an area with a harsh climate, you will need to take care of additional hydro and thermal insulation of certain elements of the sewer installation. Also, this applies to warming 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 you wish - use the services of the organization from which you bought Unilos Astra. It is also not recommended to install it at low temperatures.

    The characteristics of the septic tank are impressive. The main thing is the lack of smell, which in the country with its compactness affects comfortable living. Discard water in a neighboring pond and breed crucians.

    The possibility of a sewerage device for the whole holiday village in general from the realm of fantasy. Of course, the need for timely maintenance and scheduled replacement of individual parts (for our people this is a difficult issue) requires a certain organization.

    There should be a backup electric generator, insulation, providing an approach for maintenance and arrangement of the neck. With proper care, the equipment will process waste water for many years.

    • Sergei

      Alexander, your comment is “pure water” advertising.Drop water into the pond with crucian carp !? I see regularly what kind of water is discharged from the station, and during the service its brown haze is visible. I can imagine how this little pond will light on the site, poor carp.

      • Veteran

        The water should come out clean, you just need to configure the septic tank to work properly. The adjustment is made by raising or lowering the switch in the first camera.

  2. Svetlana

    Hello. You write that the system is silent, and the neighbors have the same green box buzzing almost like a transformer. Is it possible to make it really silent?

    • Stepan

      Your neighbor either has the lid open or some kind of malfunction. Yes, the autonomous sewage system is not absolutely silent, but you will only hear it working with the lid closed if you come close to it. By and large, there is nothing to make noise there - all the sound is from a compressor chasing fluid.

      Another thing is that this septic tank “Astra” is far from ideal. In addition to the shortcomings, which are described in the material above, I also note that a voltage regulator is extremely necessary for its operation. Unfortunately, representatives of the company that installs them do not always talk about this. For example, I only found out about this for a year changing a burned-out valve.
