Overview of the Eco-Grand septic tank: device, principle of operation, advantages and disadvantages of the system

The principle of operation of the Eco-Grand septic tank

The plant is made of polypropylene and has four production departments. Staged cleaning and pumping of water is provided by four airlifts. Aerators, which are installed in two chambers, receive air in the device thanks to compressors located in the instrument section. No additional liquid will enter the unit, as the septic tank cover is waterproof and has a unique air deflector.

The plant uses biological sewage treatment, as well as oxygen low-pressure aeration. The unique features of the operation of the Grand septic tank: the presence of an auxiliary filter in the second chamber of the device, the absence of mechanical clamp connections and additional forced control of the exit of sewage effluents.

Characteristics of the Eurobion septic tank: 5 service processes

A septic tank in a summer cottage performs an important task - waste disposal. Among the popular models, Eurobion cleaners have proven themselves well. The model range is quite wide, you can purchase a device based on your needs and financial capabilities.

The principle of operation of the septic tank "Eurobion 5"

The Eurobion septic tank has a simplified design. Already at the first stage, the process of wastewater treatment begins. In total, 4 principles of operation of the cleaning structure can be distinguished.

The principle of operation of the septic tank "Eurobion":

1. Feces enter the first chamber, where an aerator is mounted, which pumps air for the vital activity of bacteria. There, wastewater is mixed and crushed. Water from the second chamber enters the first compartment, which increases the number of microorganisms.
2. The first compartment is equipped with an intermediate bottom with a sump. Solid fractions and effluents fall into it. Silt also settles at the bottom of the chamber.
3. From the sump, the liquid moves to the next compartment, where it continues to settle and decompose under the action of bacteria. This chamber has an airlift that provides water supply and circulation. This is where the biofilm is removed.
4. The next stage is the tertiary sump. It is represented by a pipe with an installed aero drain. The tertiary sump is responsible for discharging liquid from the device.

The septic tank should always be 75% water.This level is considered optimal. If there is not enough liquid, then the drains begin to move between the chambers and are not removed from the device.

Treated effluents are moved to a pit, reservoir, filtration well.

Eurobion septic tanks are quite compact devices, which made the device cheaper. The design has both its advantages and disadvantages. Among the minuses, the absence of a stabilizer makes itself felt, which makes it difficult to take sludge. The main advantages are low weight of the structure, easy installation and maintenance, good performance.

Eurobion septic tank maintenance technology

Caring for a septic tank is quite simple, which is due to the simple design of the cleaning equipment. All actions can be done by hand. Maintenance is similar to preventive cleaning by other manufacturers.

Septic tank maintenance includes the following processes:

It is necessary to monitor the transparency of the liquid at the outlet,
Once every 3 years, it is advised to check the condition of the compressor membrane,
Once a month, the condition of the septic tanks is assessed,
It is important to control the presence of unpleasant odors,
At the outlet, the presence of silt in the water should be checked.

All work is quite simple to perform, and their observance guarantees uninterrupted operation of the device. Similar actions are performed when caring for other septic tanks.

But in order to avoid any breakdowns, it is important not only to do a periodic inspection of the device, but also to operate it correctly.

Cleaning in the device is carried out by aerobic bacteria. Their nutrition completely determines the operation of the septic tank.

Do not add chemicals to drains. Only biologically pure materials can be used. Insoluble waste is sent to the trash can.

The model range of the septic tank produced by "Yubas"

The model range is represented by Eurobion septic tanks over 10 different options. Everyone can find the best option among the representatives of Yubas cleaning devices. Models differ in performance.

Features of the most popular models:

1. Eurobion 2. Able to process 400 liters per day. This is enough for a family of two.
2. Eurobion 3. It is characterized by a capacity of 600 liters per day. Suitable for use by three tenants.
3. Eurobion 4. The model processes 800 liters of waste per day. This volume is guaranteed by a family of four.
4. Eurobion 5. Purifies 900 liters of fluid per day. The model is designed for five tenants.

The higher the performance, the higher the cost of the device. At the same time, models with higher performance are presented on the market. Designs capable of processing large volumes are used for several houses at once.

Different models differ not only in performance, but in size and salvo ejection.

All models have common design features. So the cleaning process is accelerated thanks to the U-shaped remover. It acts on the surface film of the waste.

5 ERGOBOX 4

The body of this treatment plant is manufactured using rotational molding technology, which guarantees the absence of seams and uniform thickness of the material. As part of the septic tank, Japanese compressors and German pumps are used in order to ensure the smooth operation of the entire system. In case of loss of power, the station can operate normally for two days, after which it switches to the mode of an autonomous septic tank with an anaerobic filter.

Users note, first of all, the excellent value for money of this model.With a capacity of 800 liters, it consumes only 1.5 kW per day and provides a volume of water disposal sufficient for the permanent residence of 4 people. It is possible to choose both a gravity-fed version of the installation, and a variant with a forced ejection of wastewater for areas with a high level of groundwater.

Autonomous horizontal cleaner, which does not require energy sources, consists of 2 sections with a capacity of 600 liters each. It is used in wetlands, with a high level of groundwater.

On the sides, sealing couplings are mounted in the septic tank, which hermetically connect the body of the tank to the vent pipe. The rigidity of the structure is ensured by a rectangular shape with ribbed side surfaces.

During the day, the septic tank discharges up to 500 liters of wastewater, with a filtration field, the degree of purification is up to 95% (without it - only 60%). The system provides for the possibility of pumping out sludge thanks to pipes with a diameter of 16 cm. The diameter of the filler neck is 22.5 cm.

In addition to the two-section tank, the kit includes pipes for external sewerage, plugs, sealing and push-on couplings, a fan pipe and a tee.

Expected cleaning quality

The quality of wastewater treatment directly depends on the state of the microflora. Immediately after connecting the septic system, the outlet water has a cloudy appearance.The plant needs to be in operation 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 effluent can be checked by taking a sample from the tertiary clarifier.

If the number of people living is less than the size of the septic system, it will take much longer to reach full capacity. The process can take from 6 to 12 months.

A cloudy residue in samples taken from the tertiary clarifier indicates problems with the system. As a rule, this can be caused by washout of activated sludge or its low concentration. Most often, such consequences occur during volley discharges.

Sometimes this is a consequence of clogging of one of the pipes of the system. After the installation 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 for a mechanism for neutralizing chemical impurities.

This is what a septic tank sample should look like. The first sample with a small amount of finely dispersed sludge was taken from the primary clarifier. The second sample was taken from the tertiary clarifier. Water quality should be checked periodically

Treated domestic sewage does not have an unpleasant odor and can be drained into a gutter or swamp. It is impossible to discharge into rivers or other bodies of water, 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 cannot install it in the device’s tank itself. Since the water in the station constantly circulates between the compartments. This requires a drainage well.

The diagram shows a variant with the installation of a filter well for the post-treatment of wastewater processed by the station. The clarified and disinfected liquid drains through the soil filter and is disposed of in the underlying layers (+)

An alternative method of purification is the UFO installation. The plastic of which the body is made is resistant to UV rays. If the station is installed in a nature protection zone, then it needs additional modernization. Equipment can be ordered on the manufacturer's website.

Maintenance and repair

Maintenance procedures for the Poplar septic tank (standard, Long or Long PR) can include both planned work (insulation, routine inspection) and repairs (work with the replacement of consumables or entire septic tank assemblies). Preventive maintenance, including inspection of the design of the Poplar septic tank, replacement of certain elements if necessary, and cleaning of accumulated suspensions from wastewater, is done once a year. During preventive work, it is necessary to check all components for serviceability, including electrics, compressors and other elements of the Topol septic tank.

Other scheduled maintenance work after installation includes work on the insulation of the Topol septic tank. In this case, the compressors and the pump are removed, and sand bottles are placed inside. The lid of the septic tank is equipped with heat-insulating materials. A photo of the design is shown below.

If a breakdown is detected, repairs are required, which is better not to do it yourself. In many cases, an attempt to repair it yourself leads to even greater damage to the Poplar septic tank, and in the event of a factory defect, the device cannot be returned under warranty. If a breakdown is detected before the start of operation of the device, it is worth checking according to the instructions whether the installation was carried out correctly, and then contact the manufacturer.

How to choose the right model?

Eco-Grand septic tank models differ in performance, which is reflected in the name of the device. For example, "Eco-Grand 5" is designed to service a house in which five people live permanently, "Eco-Grand 8" is designed for a cottage with eight residents, etc.

These two models, as well as the Eco-Grand 10, are considered the most popular in private housing construction.

This table allows you to accurately determine the performance and other characteristics of individual models of the Eco-Grand septic tank, taking into account their modification

Separately, it is worth mentioning the smallest device from the family of these septic tanks - "Eco-Grand 2". It is characterized by low performance and moderate price. Suitable for small cottages that are used only in the summer.

Of course, the name of the model is a very conditional indicator, you should focus on the exact technical characteristics of each device:

• "Eco-Grand 5" - performance 1 cu. m per day, volley discharge no more than 250 l;
• "Eco-Grand 8" - performance 1.6 cubic meters. m per day, volley discharge no more than 470 l;
• "Eco-Grand 10" - productivity 2 cubic meters. m per day, salvo discharge no more than 790 l.

Other models of these septic tanks are more productive, for example, the Eco-Grand 15 can be used to process wastewater from several small houses at the same time. "Eco-Grand 150" is a powerful device that will satisfy the needs of a hotel or a small town.

In addition, there are two special modifications of Eco-Grand septic tanks, designed to improve its performance in particularly difficult conditions:

• Standard - devices with a pipe insert at a depth of 0.8 m;
• Long - models in which the sewer pipe is inserted at a depth of 0.8-1.4 m due to the increased level of groundwater;
• Long elongated or Superlong - a modification with the possibility of low installation of a sewer inlet (from 1.4 m).

The septic tank model should be selected not so much for the number of residents, but for a specific amount of waste. If it is intended to service not only the house, but also the pool or bath located on the site, it is better to give preference to a more powerful septic tank model.

It also makes sense to take a larger sewer device if the number of permanent residents increases in the near future or guests often stay in the house. However, buying an overly large septic tank “just in case” is not worth it. The purchase of a device, its installation and maintenance will cost more, but these costs will not be justified.

How to choose a septic tank for home and garden

A septic tank is a container made of waterproof durable material. Distinguish designs with a simple and complex structure. The first are sealed tanks used to accumulate wastewater. The second is divided into several branches. Waste water, passing through the system, is filtered in several stages:

• effluent sedimentation process.The first compartment serves as a sump. Water enters it directly from the sewer. In this compartment, solid particles settle to the bottom;
• filtration by anaerobic microorganisms. Water enters the second compartment by gravity or with the help of a pump. Waste is processed, turning into gas fractions and sludge. In this case, water clarification occurs;
• final cleaning in the filtration well. Passing through the perforated walls and the drainage layer, water is absorbed into the soil.

Compared to a conventional cesspool, a septic tank has the following advantages:

• wastewater is treated in a natural biological way, and soil pollution does not occur;
• long service life;
• isolation of unpleasant odors;
• no need for frequent use of the services of sewers.

Septic tank Poplar Eco Grand: the principle of operation and installation

Many people, in order to escape from the bustle of the city, acquire country plots for themselves, because the dacha is an ideal place for physical and mental relaxation.

And so that the rest is not overshadowed by anything, the first thing to do is to equip an autonomous sewer. This is difficult to do without a suitable septic tank - cleaning equipment.

Varieties and characteristics of septic tanks of a domestic manufacturer

If we consider septic tanks using the example of Topol products, it can be noted that they are offered in a wide range.

Each of the main models is marked with the words "Long" and "PR".

In the first case, this means that the station can be placed deep in the ground, and the second abbreviation indicates that the system is equipped with a drainage pump for forced pumping of purified water.

The main models of Poplar septic tanks:

Eco-Grand 3 - suitable for a family of three.It consumes 0.9-1.2 kW per day, withstands discharge of 170 liters of water at a time, productivity is 1.1 m 3 / day;

Septic tank Poplar M

The septic tank Topol M and Topas cope no worse with the processing of domestic wastewater.

What is inside the Poplar septic tank and how does it work?

Autonomous sewage Poplar has its own design features.

It does not have metal parts, therefore it does not oxidize, and has a long service life.

According to the scheme of the Topol device, it includes a primary settling tank, an aerotank, a secondary settling tank and an "activated sludge" settling tank.

How cleaning will take place depends on the presence of the following elements:

Topol Eco grand

• input of effluents;
• coarse filter;
• airlift recirculation, pumping sludge, stabilized sludge;
• main pump;
• compressors;
• a device for collecting particles that are not recycled;
• water level sensor;
• box for connecting the supply cable;
• Control block;
• outlets for compressors.

Septic tank cleaning scheme Poplar

The basic scheme of treatment is similar to those used by other types of treatment plants.

The principle of operation of a septic tank is as follows:

• wastewater enters the receiving chamber by gravity. Here, due to the presence of an aerator, large pollution is divided into smaller ones;
• the second stage of purification takes place in the aeration tank, where water is supplied by an airlift. In this place, organic impurities are processed by aerobic microorganisms;
• already purified water enters the sludge sump and is separated from the sludge;
• in the cavity of the secondary sump, smaller inclusions and suspensions are deposited, and the most purified liquid comes out. This can happen under duress or on its own.

Construction installation and maintenance

Installation of a septic tank Poplar

1. first, the soil is examined, the location and depth of the septic tank are determined;
2. a pit is dug out and at the same time, trenches for the pipeline;
3. if the groundwater level is high, then it is advisable to construct a timber formwork;
4. the container clings to the eyes and descends into the pit, but so that it can stand evenly and firmly, before this the bottom of the pit must be covered with sand and gravel;
5. sewer pipes are mounted and connected, an electric cable is laid, commissioning is carried out;
6. at the end, the septic tank falls asleep.

This is what a septic tank looks like

Maintenance consists of periodic cleaning and preparation for the winter period.

Advantages, disadvantages, price

Reviews of Poplar septic tanks are mostly positive, their reliability, durability, high degree of cleaning, ease of maintenance, and non-sensitivity to soils are noted.

Poplar Eco for home and garden

But there are some disadvantages: energy dependence, an urgent need to comply with the rules of operation.

For example, you can not dump large garbage, substances that can not be processed by bacteria, mushrooms, fruits and vegetables.

The use of household chemicals should be limited.

The advantages of the equipment include the installed alarm system.

The price of a septic tank will be 118-143 thousand rubles

The price of a septic tank depends on its volume and performance.The estimated price for varieties of Topol 3 models is 65-68 thousand, Topol 5 costs 75-103 thousand rubles, Topol 8 will cost 94-113 thousand, and Topol 10 - 118-143 thousand rubles.

Maintenance of septic tanks Topas and Eco-Grand

In order for the treatment equipment to work smoothly, it is important to fulfill the following requirements:

• Perform visual inspection once a week. It is enough to open the lid and watch the work.
• Once a quarter, clean the systems from debris and accumulated sludge.
• Change the compressor membranes every two years.
• Every 5 years, clean the bottom of the receiver and aeration tank from mineral deposits.

With the exception of these low-effort measures, treatment plants operate independently and do not need constant monitoring. And if you monitor the operation of the device well, then you can not worry about possible breakdowns and expenses for the repair of Topas and Eco-Grand septic tanks.

How does it work

To understand the principle of operation of the DKS septic tank, it is necessary to trace the entire path that drains pass inside the device itself:

1. From the sewer pipe, all drains enter the first tank or sump. This is where the light comes in. Heavy fractions precipitate, and clarified effluents flow into the second compartment. The pipe through which the communication of liquids between the tanks takes place is at a height of 1/3 of the height of the entire sump. This arrangement allows only the clarified liquid to flow, and the sediment remains in the first container.
2. In the second compartment (which in principle is also called a sump) there is a final settling of all suspended particles. A sediment of small particles remains at the bottom of the container. In both settling tanks there are colonies of microorganisms - these are methanogenic bacteria.As a result of their vital activity, organic residues decay.
3. After passing through clarification in both settling tanks, the effluent enters the biofilter. Here the fine particles remaining in the water are filtered. Also in this part of the septic tank, cleaning continues with the help of aerobic microorganisms. The filter itself is a feed tube, a sprinkler and a brush load. Through the tube, water slowly enters the biofilter and is sprayed over the bioload, which has a large surface due to the special structure. In the brush load there are colonies of aerobic bacteria.
4. After passing through the biofilter, the treated wastewater enters the storage tank. Here is a drainage pump that works offline. The tank has a float system. As soon as the water level rises to a certain level, the pump turns on. Thus, treated wastewater is pumped out of the tank into a drainage well or simply into the ground.

In other cases, instead of a tank, a branch pipe is displayed, which is connected to the drainage system. With its help, water passes additional soil filtration before it enters the environment.
