The evolution of septic tanks Eurobion
Part of the development was improved empirically, during the release of the first models. Refinement was carried out on the basis of those problems that arose during operation by end consumers. The first models had a number of design flaws.
They did not have an anchoring system, and with an increase in the level of groundwater, the ascent of the tank occurred. This led to pipe deformation, and in some cases to failure of the sewage system.
Customers massively contacted the company that traveled and on-site upgraded the Eurobion septic tank. The cost of extracting the capacity was paid in the amount of 50% of their value.
After identifying this shortcoming, soil hooks were added to all models. This resolved the ascent problem. Special hooks were mounted in the corners of the installation, which at that time had a rectangular shape. She was not a good decision either.
Since the tank had an elongated rectangular body, there were cases of depressurization with excessive pressure on the walls of the tank. This was due to the presence of a large number of welds.
The number of joints was reduced by making a cylindrical body. Additionally, it was reinforced with stiffeners on four sides.
As a consequence, this problem was partially solved. In areas where during winter periods the temperature drops below 25 degrees, the upper part of the tank needs thermal insulation. This is necessary to maintain the optimum temperature for the propagation of active sludge in it, which purifies wastewater.
The manufacturer has actively improved the purification system and to old models there is an opportunity to purchase a kit for modernization, which solves the problem of excessive removal of active biological mass during salvo discharge of water.
This has improved the quality of domestic wastewater treatment. The last modernization took place in 2015. She touched on those station models that are designed to accept domestic wastewater in households where 12-15 people live.
Expected Cleaning Quality
The quality of wastewater treatment directly depends on the state of microflora. Immediately after connecting the septic system, the outlet water has a cloudy appearance. The installation needs to be operated for several weeks to reach full capacity. During this period, the percentage of purification does not exceed 70%.
To prevent environmental pollution, the active microbiological mass can be populated immediately after installation. The system does not provide for the use of aeration fields, so the final quality of the effluents can be checked by taking a sample from a tertiary sump.
If the number of people living is less than how much the septic system is designed, reaching full capacity will be much longer. The process can last from 6 to 12 months.
Sometimes this is a consequence of the clogging of one of the pipes of the system. After the unit reaches full capacity, the water should not contain fine suspension.
But even transparent drains contain a large amount of phosphates and other surfactants contained in detergents. The design of a standard septic system does not provide a mechanism for neutralizing chemical impurities.
Treated domestic sewage does not have an unpleasant odor and can merge into a gutter or swamp. It is impossible to discharge into rivers or other water bodies, as this leads to phosphate poisoning of the local biological flora and fauna.
The company allows you to separately purchase a dispenser for wastewater disinfection, but you can’t install it in the device’s tank itself. Since the water in the station is constantly circulating between the compartments. This requires a drainage well.
An alternative method of purification is the installation of UV. The plastic of which the housing is made is resistant to UV rays. If the station is installed in a conservation zone, then it needs additional modernization. Equipment can be ordered on the manufacturer’s website.
Design and principle of operation
Water purification includes two three stages. Accordingly, the tank itself has three compartments. It reduced the number of aerial lifts to one. It has an inner diameter of 28 mm. There is one compressor and one aerator. The diagram shows a detailed design of a biological treatment plant in which aerobic and anaerobic bacteria.
The step-by-step cleaning process is as follows:
- Through the inlet pipe, water enters the receiving vertical oxidizing channel.
- There, solid fractions are broken by a coarse bubble aerator.
- The suspension obtained after oxygen breakdown settles on a false bottom, which has a slope and an overflow hole.
- A fine suspension settles through the hole at the bottom of the activation tank.
- Active sludge forms at the bottom.
- Suspended water is moved by airlift to a secondary sump.
Further, the water circulates through the system until its level rises for transportation from the system. As the mass of activated sludge increases, the quality of the purified water also increases.
Aeration of sludge occurs in a continuous mode, which over time necessitates the cleaning of the device. Aeration elements of Russian production are installed in the station. Their cost is lower than foreign analogues.
Model line “Eurobion Yubas”
The company produces several configurations of septic tanks Eurobion. They differ in the volume and the presence of some additional functions.
The model line is represented by the following devices:
- Eurobion-5R ART
- Eurobion -5R ART Midi
- Eurobion -8R ART
- Eurobion -8R ART Midi
- Eurobion -8R ART long
The number in the abbreviation means the number of people for which the installation is designed.The Midi and Long models are designed for high groundwater areas. This is not a complete lineup.
Characteristics Eurobion-5R ART
Installations of this type have a capacity of up to 900 cubic meters. liters per day. Designed for year-round use in a private household, where 1 to 6 people live.
They have a volume of 2.38 to 2.80 cubic liters. The hole for the drain pipe leaving the house is set at 60 -80 cm. The maximum salvo discharge does not exceed 390 cubic liters.
Characteristics Eurobion-8R ART
These models have a capacity of up to 700 cubic meters. liters per day. Designed for year-round use in a private household, where 6 to 9 people live.
They have a volume of 4.35 to 6.12 cubic liters. The hole for the sewer leaving the house is set at 60 -120 cm. The maximum discharge of effluents is limited to 700 cubic liters.
Rules and frequency of care
Since the primary sump has a small volume, it must be pumped out with a pump or every 6 months.
Then it is mixed with the remains of vegetation and other substances suitable for fertilizer. To reduce the pumping frequency, an overflow well can additionally be installed. Then the waste water will fall into it, and only then into the installation. This will prevent non-degradable debris from entering the septic tank and possible breakdowns.
The use of an overflow well in the sewage system will also reduce the leaching of activated sludge with large volumes of one-time water supply to the installation.
At intervals every two or three years, you need to change the membrane compressor. If a timer is set, then membrane replacement may be needed earlier.
In addition, it is necessary to reduce the amount of chlorine-containing household chemicals, which destroys activated sludge. The remnants of rotten vegetables and other food should not be allowed to enter the septic tank. This negatively affects microorganisms.
Cons and pros of these septic tanks
By analogy with all septic tanks for biological treatment, Eurobion Yubas have advantages and are not without drawbacks. The advantages of the station include the shape of the tank, which has a small number of welds and is reinforced with stiffeners. Another advantage is the presence of one aerial lift and a minimal presence of electronics.
All electrical appliances are assembled in a separate compartment and are available for maintenance.The presented septic tank models are lightweight and compact in size. This simplifies the transportation and installation of stations.
Shortcomings include insufficient purification of household wastes from phosphates. In addition, the station needs constant monitoring. Every 6 months needs maintenance. The aerator operates continuously, which reduces its service life.
The chamber, designed for primary discharge of wastewater, has a small volume, which leads to leaching of activated sludge from the station. The septic tank is powered by electricity, so this increases the cost of its maintenance. The drawback is the location of the ventilation hole on the cover.
In some cases, moisture is caused by snowmelt. This happens when it hits the station cover. Damage caused by moisture on the electronics does not apply to warranty cases. Repair is carried out at the expense of the owner.

Comparison of septic tanks with major competitors
According to the degree of cleaning, “Topas” can be ahead of “Eurobion”, if the basic complete set of “Topas” is supplemented by the Ural federal district system. It is offered by the manufacturer as an option.
Astra also does not have this disinfection mechanism. Housings of tanks "Topas" and "Astra" have a rectangular shape with a large number of welds. This makes containers more susceptible to deformation and depressurization.
Eurobion has a cylindrical body, which compares favorably with its closest competitors. Since there is one seam on the tank. This makes its body more resistant to compression and deformation.
The number of aerial lifts in the biological treatment plants “Topop” and “Astra” is three. The width of the tubes is approximately the same. Eurobion has only one airlift with a large pipe diameter. This distinguishes it, since blockages in the system are minimized.
Another advantageous feature of the Eurobion Yubas septic systems is their lower electronics content.
There are two compressors in the Topas models, and two aerators in the Astra septic installations. In "Eurobion" these devices are present in a single copy. This reduces the cost of installation maintenance. In addition, the control unit in the Topas and Astra systems is controlled by a float switch sensor.
