Overview of the septic tank "Rostok": design, technical characteristics and nuances of operation

How the system works

By its nature, Rostock is a kind of filter for water purification, which makes it suitable for technical use, watering plants or simply throwing it into the ground without sad consequences for the environment. The manufacturer guarantees cleaning up to 98%.

The system works according to the following scheme:

1. Water with the waste products contained in it enters the first tank of the septic tank.
2. It separates the liquid from the sludge by settling under the action of gravity.
3. The sludge remains in the first chamber, the liquid passes on.
4. Entering the second compartment, the water passes through a mesh filter, and then through a layer of ziolite. Here the water is purified by 90%.
5. Then the effluent enters the biofilters, where it undergoes post-treatment before being released into the soil or a roadside ditch.
6. The final stage is the collection of treated water in a designated place.

Comparison of advantages and disadvantages

When choosing a septic tank, we, of course, are interested in its advantages, not forgetting to ask about its disadvantages. After all, before buying, you must definitely weigh both: the decision depends on what outweighs in each individual case. Therefore, we will talk about the pros and cons of the Rostok treatment plant.

We list the obvious advantages of the device.

• Strength and durability. The body of the product is made by a one-piece casting method: the chambers are not separated from one another. If we take into account the presence of stiffeners, then you can be sure that this design will be durable and last a long time.
• Unpretentiousness to operating conditions. For the Rostock septic tank to work, it does not need to be connected to the power supply. It turns out that it can be used in an area where there is no need to talk about a developed infrastructure yet.
• Quality of work. This device provides a high degree of wastewater treatment. When biologically active preparations are added to Rostok, we can safely say that the wastewater will be cleaned up to 92%. Oils and fats do not enter the second chamber of the tank at all.
• Ease of installation. The device does not require special skills during installation and in bringing the septic tank to working condition. For this purpose, it is not at all necessary to involve professionals: you can handle it yourself.
• Reliability and security. The inlet pipe of the device is equipped with a damper, thanks to which even a sharp discharge of a significant amount of water into the sewer will not lead to water hammer.

The installation pleases with the thorough thoughtfulness of the design.The nozzles of the device (inlet and outlet) are attached to the body using flexible elements, which allows them to remain intact even if the tank itself moves during seasonal ground movements.

This device also has disadvantages:

• Light weight. The low weight of the device is a significant advantage during its installation, which can also become a disadvantage if we consider the risk of it “floating” from the ground during periods of seasonal groundwater rise. Although the shape of the "Rostock" does not contribute to this process, it is better to consider the possibility of constructing a concrete base to secure it.
• Occupancy of the site. The dimensions of the septic tank "Rostok" country allow us to assert that it will occupy about 4 m2 of the area of ​​​​the site. This zone cannot be planted with anything other than grass and small shrubs. On this site, with the addition of a meter around its perimeter, it is impossible to equip a parking lot, since the septic tank can be accidentally pushed through.
• Waste disposal costs. Pumping of unfiltered waste should be carried out with the help of sewers. This means that this item of expenditure should be included in your budget as well.
• Device location. "Rostok" can not be placed where it pleases. It is imperative to take into account both sanitary standards and the fact that a sewage truck should drive up to it. So it must be close to the road.

The disadvantages include the nuances of the design of the device: it does not provide for the possibility of a number of drains entering the second chamber immediately. But drains from washing machines and dishwashers, which contain various detergents, should flow here.This chemistry can destroy the beneficial bacteria that are part of the bioenzyme products that are used in septic tanks.

As for the price of the device, then opinions differ. Therefore, we did not attribute this factor to either advantages or disadvantages. When you choose a septic tank for your summer cottage, then decide for yourself how much this purchase matches your financial capabilities.

The lineup

There are four main models of septic tanks for sewerage:

1. "Country", designed to serve a family of two or three people. Its capacity is 1500 liters, weight is 100 kilograms.
2. "Mini", designed for a small family of two people. The volume of such a device is 1,000 liters, and the weight is only 90 kilograms.
3. Zagorodny is one of the most popular models, capable of serving four to five people. The working volume of the chamber is 2,400 liters, the weight is 120 kilograms.
4. "Cottage" - the most spacious septic tank for a family of five to six people. Its volume is 3,000 liters, weight is 190 kilograms.

In fact, any of the listed models can be installed by the owners on their own, without the involvement of special equipment. And only for cottage models you may need a winch.

More detailed information can be found on the official website of the manufacturer, located at

Use and care of the device

The key element of the local treatment plant "Rostok" is easy to operate. Solid fractions accumulated in the first chamber must be periodically removed. This is usually done once a year, subject to year-round use of the device.

If operation is limited to the summer period, then the first chamber is cleaned every two years. To solve this problem, a sewer machine should be involved.

The sorption filter located in the second chamber is also reactivated about once a year. The zeolite layer is simply washed with a solution of common table salt. Filters should be changed at least once every 15 years.

To increase the efficiency of wastewater treatment, you can use special biological products. With their help, the anaerobic processes occurring in this device become more intense. Colonies of bacteria contained in additives process organic matter in wastewater, as a result of which the degree of purification increases.

Useful video on the topic

It is said that it is better to see once than to read or hear. Therefore, as visual demonstration of the principle of operation septic tank "Rostok", we invite you to familiarize yourself with this video:

The following video will acquaint you with the process of installing a septic tank. You will see step by step installation of autonomous sewerage "Rostok" model "Zagorodny" with the arrangement of the filtration field:

It is not true that the romance of country life must necessarily be accompanied by the rejection of city goods. On the contrary, summer holidays in the country should be as comfortable as possible.

Let you have cold and hot water, warmth on a cool day and, of course, an autonomous sewage system that allows you to dispose of wastewater without harm to the environment.

Design features

The device is a seamless two-chamber structure equipped with ribs

stiffness. For pumping out sludge and cleaning the filter, there is a manhole with a wide mouth.

The first working chamber is used for gravity settling - heavier organic masses settle to the bottom of the tank, and water flows into the second compartment.

The main purpose of the second compartment is to provide two-stage filtration - mechanical and sorption. Sludge processing is carried out by anaerobic bacteria. It must be regularly pumped out of the sump.

Device and principle of operation

Before you buy a septic tank and improve your country house, you should get acquainted with the principles of operation of the installations. Rostock is a model of a septic tank, divided inside into two chambers. The first of them is used for primary settling, the second for additional filtration. The waste disposal process proceeds as follows:

Effluent entering the first chamber through the supply pipe will be divided into several fractions, depending on the specific gravity (density). All substances that are lighter than water float to the top, heavier particles settle to the bottom;

• At the inlet of the supply pipe there is a special extinguishing device that does not allow the settled drains to mix again under the action of a liquid jet falling down;
• After settling, the primary clarified effluents are sent to the next chamber - the filtering chamber. Two types of filters are installed here - sorption and mesh.

After passing through the septic tank, the effluents are about 75% free of impurities. To achieve final cleaning, the liquid is sent to a biofilter or to a soil post-treatment device - filtration fields.

Installation and installation of a septic tank Rostock and its characteristics

People in whose lives the situation is such that it is necessary to organize an autonomous sewage system have to understand the sea of ​​​​incomprehensible information, as well as choose one from a huge number of manufacturers of plumbing equipment.

In order not to suffer for a long time in choosing, you can familiarize yourself with the technical and operational characteristics of Rostock septic tanks. I would like to note right away that this installation is completely volatile.

The manufacturer produces several modifications that differ from each other in terms of volume, configuration, and components.

Detailed description of the characteristics of the representatives of the model range

The name of the Rostok Mini septic tank indicates that it has a small capacity (250 l / day), respectively, it is designed to serve a minimum number of people.

This model has a volume of 1000 liters, and the dimensions are 1280 * 110 * 1700 mm.

Due to the material used and the absence of metal elements, the design weighs only 2.4 kg.

The one-piece cast construction is 100% hermetic, and thanks to its cylindrical shape, it firmly settles into the pit and does not float up.

The estimated cost of such a variant of plumbing equipment is 20 thousand rubles.

This is how Rostok Mini looks like

The septic tank Rostock "Country" is presented in the form of a horizontal tank of 1500 liters with an extension neck.

The system, which has a capacity of 400 l / day, is suitable for sewerage of a house in which a maximum of 3 people live at the same time.

The design has a weight of 90 kg, a length of 1700 mm, a width of 1120 mm, a height of 1840 mm.

You can buy a "Country" septic tank for 30 thousand rubles.

Septic tank Rostock "Country"

The most dimensional of the entire model range is the Cottage septic tank.

It is characterized by a maximum productivity of 1000 l / day, with a capacity of 3000 l. Dimensions: length 2360 mm, width 1440 mm, height 2000 mm.

The shape of the septic tank is the same as the "Dachny" one, it is equipped with a hermetically sealed lid that protects against foreign objects and liquids.

The price of this model is 50,000 rubles.

Principle of operation

As mentioned, the design itself has a rounded or horizontal cylindrical shape with an elongated neck.

If you look at the scheme of the septic tank, you can see two chambers in which mechanical sedimentation and filtration of waste water take place.

It is noteworthy that there are no welds inside, and there is also protection against salvo discharge.

The principle of operation of the septic tank Rostock

The entire cleaning process can be divided into several stages, and it begins with the fact that household and sewer waste enters the receiving chamber through the pipe pipe.

There, due to the action of active microorganisms, the effluents are separated into sludge, light fractions and water.

At the next stage, their second stage of purification takes place in a special sorption filter.

To ensure cleaning, there is a 200 mm layer of zeolite on the bottom of the compartment, which requires special attention in care.

It consists in cleaning, reactivating and washing with a solution of common salt.

Additional treatment tanks Rostock

Sometimes additional tanks or expanded clay, sand-crushed stone or other soil filters are installed for post-treatment.

Waste water is already 100% purified there.

The structure of the septic tank Rostock

In both chambers of the cleaning device, a sediment of sludge and solid insoluble particles accumulates over time.

They must be periodically removed from there by means of a sewer machine or handmade mechanically.

This is the only way to ensure the smooth operation of the septic tank.

Mounting Recommendations

Before proceeding with the installation of a septic tank with your own hands, you should determine its location and the level of groundwater.

It is necessary to dig a pit so that it is at least 5 m from a residential building and the road boundary, 30-50 m from a water source and 3-4 m from fruit trees.

The required pit should be larger in width and length than the container itself.

Installation of a septic tank Rostock

Be sure the bottom of the pit is supplied with a pillow of crushed stone and sand, if necessary, the septic tank must be secured with belts, ropes or fittings.

Do not forget to make sure before installation that there are no sharp stones, glass and protruding fittings that can damage the polyethylene walls.

The depth of the trench should be 1.5 m

The inlet pipe should lie at a depth of 1.5 m, a slight slope of the pipeline should be ensured.

Upon completion of all connections, the pit is backfilled and the tank is filled with water.

Device and principle of operation

The Rostock septic tank has a fairly simple device. It is a container with two chambers, one of which is equipped with a special filter. The principle of operation of a septic tank is as follows:

• sewer flows by gravity into the first chamber. The inlet pipe is equipped with a damper, which prevents the residues accumulated at the bottom from being stirred up. The first chamber of the septic tank plays the role of a sump. It separates wastewater into heavy and light fractions.The first settle at the bottom and are subsequently pumped out. Light fractions rise up along with drains;
• clarified drains enter the second chamber. In this case, the movement goes from the bottom up. There are two filters in this chamber: mesh (to remove large fractions) and sorption. The latter is a layer of a material such as zeolite. Its thickness reaches 20 cm;
• after passing through the filters, the effluents are cleaned by 70–80%. After that, they are removed from the septic tank for post-treatment. To do this, you can use soil post-treatment or special biofilters.

The Rostock septic tank is quite easy to operate. Care for him is to remove the accumulated solid fractions. This procedure is carried out with the involvement of a sewage machine about once a year. In addition, it is necessary to reactivate the sorption filter with the same frequency. To do this, the zeolite layer is washed with a solution of common salt.

To improve efficiency wastewater treatment special biological products can be added to the septic tank. They will intensify the anaerobic processes occurring in the device. Bacterial colonies will process the organic residues in the effluents and increase the degree of their treatment.

The process of work is visualized in this video:

Varieties of septic tanks "Rostok"

The Rostok lineup is not very wide, but most buyers will find a suitable option for themselves with the necessary technical characteristics. The main difference between the models is performance, which determines the size and configuration.

1. "Rostok Mini" is the smallest option, containing 1 m3 of wastewater and designed to serve 1-2 people, since the daily output is approximately 0.25 m3. The one-piece container is very compact and lightweight.Its length, width, height and weight are 1.3 m, 1.1 m, 1.8 m and 2.5 kg, respectively.
2. "Sprout Country" is a tank made of solid plastic, supplemented by a neck. The capacity of the tank is 1.5 m3, weight 100 kg, length, width and height, together with the neck, approximately 1.7 m, 1.1 m, 1.8 m. The device can process 0.4 m3 of wastewater daily, designed for home maintenance occupied by 3 people
3. Rostok Zagorodny has a configuration similar to the previous one, but the volume of the tank is much larger - 2.4 m3, which increases productivity to 0.88 m3 / day. Dimensions (LxWxH) are 2.2x1.3x2.0 m, and the weight is 150 kg.
4. "Rostok Cottage" is the largest reservoir, the length, width and height of which are 2.4, 1.4, 2.0 m, respectively, and the capacity is 1 m3. The empty tank weighs almost 200 kg and can hold 3 m3 of wastewater.

The internal design and method of processing wastewater is the same for all models.

Why choose this particular system?

When designing a septic tank, technologies were used that have been successfully operating at large treatment plants for many years. Thanks to this approach, the installation has become even more reliable, economical and durable. It is distinguished by:

• Well-thought-out optimal design of the device. The capacity of the septic tank is solid, which provides it with 100% tightness and the absence of welds, potential sources of leakage. The installation is made in the form of a cylinder, this configuration is the least susceptible to the risk of floating under the possible influence of groundwater.
• The special design of internal overflows, which makes it possible to retain oils, fats and suspended solids.
• Energy independence of the device.
• Building safety and security.They are confirmed by the results of examinations, which recognized the compliance of the installation with all the requirements of SanPIN for water treatment and for the environmental safety of the septic tank itself.
• High degree of purification. When using bioenzymatic additives, the water at the outlet of the installation is purified by 80%. If the post-treatment system developed by EcoProm SPb is used, the output is 90-95% purified water.
• Original design features that optimize system performance. Among them, built-in protection against volley discharges up to 200 liters. An inlet flow damper that prevents sediment from rising from the bottom of the tank. An emergency overflow designed for the smooth operation of the device and a thin-walled high-tech module that prevents large particles from entering the filtration chamber.
• Convenience and ease of maintenance. The unit provides easy access to all special technological openings.

Anyone who is going to install a summer septic tank sprout or any other modification needs to understand that the device only performs initial wastewater treatment. Even though it is quite high, it is necessary to provide for an additional purification system. It can be either a well or a filtration field, or a special biofilter.

EcoProm engineers, who developed the septic tank, also offer a post-treatment system. According to customer reviews, the treatment facilities mounted in this way work well, without causing problems and complaints. Another important advantage of these septic tanks is the possibility of installation and subsequent warranty service by the specialists of the manufacturer.This ensures prompt resolution of all emerging issues.

Often, people choosing a septic tank have doubts about the unusual design of the device. This is especially true of the filter bed in the second chamber, which, as they think, should be constantly clogged, and it is not possible to remove it for cleaning. In fact, this is not a mechanical filter, but a sorption one.

The thickness of the sorbing layer is only 200 mm, the fraction that fills it has a size of 30-40 mm, so it does not threaten clogging. Especially considering the location of the filter - before leaving the septic tank, after a thin-layer block that traps mechanical impurities.

Sewage from the septic tank requires mandatory post-treatment

Feedback from those who use the device suggests that you should not be afraid of the innovations implemented in this model. They make the system more efficient and safer. A septic tank sprout, properly installed and undergoing regular maintenance, allows you to forget about problems with wastewater.
