Overview of the septic tank "Cedar": device, principle of operation, advantages and disadvantages

How to install a septic tank?

Installation of the device is quite possible to do it yourself. The septic tank is small, weighs a little, which facilitates the work.

How to choose a seat

Before installation, a place for a septic tank is selected. You should focus on the requirements that are specified in the regulatory documents. If the septic tank is installed incorrectly, then you can create a danger to others. Impurities can seep into the source of clean water if the distance is not observed. If you put a septic tank close to the house, it can begin to erode the foundation. They also take into account the need to organize a filtration system on the site, the need for periodic pumping of wastewater, which implies a free access to sewage equipment.

Installation step by step

At the installation site, a contour for a septic tank is outlined.A pit of the required diameter is dug along it. When digging the depth of the pit, take into account the height of the device, including the size of the sand and gravel pad, the concrete layer. Therefore, up to thirty-five centimeters should be added to the total height. The width of the pit should be more than a septic tank up to twenty centimeters.

At the bottom they arrange a sand and gravel pillow fifteen to twenty centimeters high. The layers are rammed, then the base is made of cement up to fifteen centimeters. A concrete slab can be used as a base.

Comparison with competitors

Despite the growing popularity, Unilos septic tanks have quite strong rivals. Such well-known brands of septic tanks as "Tank", "Triton" or its analogue "Triton-mini", "Topaz", "Tver" have long been heard by the owners of suburban real estate.

• If we compare the common "Topaz" and "Unilos", then it is worth noting that with approximately the same price category, the latter is more adapted to the conditions of the Russian climate, since it was created and developed by our compatriots.
• The powerful Tank unit perfectly cleans wastewater, but compared to the Unilos septic tank, it requires fairly frequent cleaning.
• Tver has to be subjected to fairly frequent and regular maintenance, and the quality of wastewater treatment is lower than that of Unilos.

The developments of the Russian company "Unilos" in the field of local cleaning systems have won the lasting love of consumers

When choosing a wastewater treatment system, it is necessary to pay attention to the installation accuracy and correctly calculate the water consumption. And, based on these parameters, select a treatment system of appropriate capacity

The device and principle of operation of the septic tank Cedar

Autonomous wastewater treatment systems differ from each other both in terms of the principle of operation and in cost. The Kedr septic tank is a container made of high-strength polypropylene, which is divided into four compartments. Each of the compartments performs its own cleaning function, preparing the water for a safe return to the natural environment.

During the cycle, both mechanical and biological cleaning takes place. For biological treatment, special biological products are used that have a decomposing effect on organic matter. Thus, the lack of a centralized sewage system is not an obstacle to organizing high-quality drainage and subsequent wastewater treatment, and the cesspool is a thing of the past, and will not spoil the presence in the suburban area with its appearance and odors emanating from it.

Pros and cons of using

Before buying any treatment plant, it makes sense to carefully study its advantages and familiarize yourself with the disadvantages so that there are no unpleasant surprises in the future. Advantages of using the Kedr treatment plant:

the model can be used both for servicing the local sewerage system of the dacha, and for any other facility where the water consumption does not exceed 1000 liters per day (this performance is quite sufficient to serve a house with 4-6 people living);
minimum operating costs, for a long time the treatment plant does not require attention. But periodically (about once every 1.5 -2 years) it is necessary to clean the sedimentation tanks from the accumulated sediment.

• rather simple installation, when installed in the central strip, additional insulation is not required.If installation is carried out in the northern regions, the case should be insulated. To perform installation work, there is no need to hire special lifting equipment, since the septic tank weighs 150 kg and can be installed manually;
• long service life of the unit is ensured by the absence of a tendency to corrosion, as well as a simple and reliable design. There is simply nothing to break in a septic tank, so the probability of a system failure is very small.

The most significant disadvantage of the installation is that it does not provide a sufficiently high level of cleaning. Therefore, water cannot be discharged without additional post-treatment. It is necessary to build additional sites for filtration, and this requires additional costs.

In addition, the septic tank needs periodic pumping of sediment. Therefore, when choosing a place for its installation, it is necessary to take into account the fact that a sewage truck will have to drive up to the septic tank.

You can install a septic tank near the house, but no closer than five meters from the foundation. When choosing an installation site, you need to remember that an entrance for a sewage truck must be left to the septic tank. The installation works autonomously, but in the event that it is necessary to pump out water forcibly, a drainage pump will need to be connected.

Choosing a manufacturer of septic tanks for a summer residence

Among domestic manufacturers, stations from:

GK "TOPOL-ECO" - various models of "Topas".

"Triton Plastic" - "Tank", "MikrobMini" and "BioTank".

PC "Multplast" - "Termite" and "Ergobox".

"SBM-Group" - "Unilos" with modifications "Astra", "Cedar" and "Mega".

Products from various manufacturers

Septic tanks for dachas of these manufacturers occupy the lion's share of the Russian VOC market. Owners often refer to their products as their best bet. In the range of these factories there are models both anaerobic non-volatile and more productive aerobic with pumps. Among them there are modifications not only for standard soils, but also for areas with high GWL.

Of the foreign manufacturers, only Finnish Uponor is worth mentioning. If the dacha is located in the North-West of the Russian Federation and preference is given to imports, then it will be difficult to find a better septic tank. This company offers several solutions for a different number of people living in a cottage. There are plenty to choose from. Here, it is like a roof made of metal tiles - there are domestic and imported products on the market. The choice is at the discretion of the buyer.

Pros and cons of the septic tank "Cedar"

The sewer installation has a number of positive and negative characteristics that must be considered when choosing a septic tank for a suburban building. The advantages of "Kedra" include:

• Energy independence. The system does not require electricity, so you do not have to spend additional money for paying for electricity.
• Easy installation without the involvement of special equipment. Installation work can be done independently.
• Tightness and strength of the tank. High-quality polypropylene, from which the container is made, is not subject to corrosion, and the cylindrical shape of the tank and internal partitions provide resistance to the pressure of soil masses during heaving. The monolithic capacity eliminates the possibility of leakage.
• Long service life. According to the manufacturer, the station will last more than 30 years.

The disadvantages of the Kedr septic tank are the following points:

• Effluent needs additional treatment, since in the tank they are cleaned by 75%. For this reason, it is necessary to use additional area of ​​​​the site for the installation of a drainage trench or filtration fields.
• The station cannot be installed if the groundwater runs very high.
• There is an additional cost item for the purchase of biomaterial to improve the quality of cleaning.

Septic tank device

The Kedr septic tank is a non-volatile device that works in tandem with soil post-treatment systems.

The unit provides primary clarification of wastewater, which is then subjected to additional treatment when passing through drainage wells or filtration fields, from where it goes into the underlying soil layers.

The need to equip additional filtration systems does not allow the use of a sump in soils with a high occurrence of groundwater.

Soils characterized by good permeability are considered the most favorable for the installation of Cedar septic tanks: sands of all degrees of density and fineness, gravel and crushed stone deposits with sandy aggregates.

Installations of this type are superior in their class to storage tanks in which sewage is accumulated and stored until it is pumped out by a sewage machine. But at the same time, they are not able to provide such a degree of purification as septic tanks with deep biological treatment, after which the filtered water becomes safe for the environment and can flow directly into the ground, into sewers or open water bodies.

Sewer drains, passing through the septic tank, are not completely cleaned of biological and mineral impurities and require additional filtration, which is carried out in the filtration field or in the absorption well

The septic tank is a fully sealed tank made of polypropylene. Inside the installation there are four chambers isolated from each other.The chambers are arranged in such a way that water, having passed the next stage of purification, can freely enter the next compartment, where it undergoes a higher degree of purification.

The interior of the septic tank consists of:

• a receiving chamber with a volume of 1500 liters, in which separation into liquid effluents, solid insoluble sediment and fat takes place;
• an anaerobic treatment chamber with a volume of 1500 liters, in which liquid effluents are fermented and clarified under the action of anaerobes;
• chambers for deep aerobic purification with a volume of 750 liters, where organic inclusions are processed by active microflora;
• clarifier chamber, in which the final clarification is performed.

If it is necessary to artificially stimulate the drainage of wastewater, pumping equipment can be installed in the fourth compartment.

The Cedar septic tank has a compact size, it is made in the form of an oval (diameter 1.4 m), vertically located structure, three meters high. The weight of the device is 150 kg. The standard head of the septic tank is 1/3 of the structure. If necessary, the manufacturer can produce a unit with a higher, or vice versa, low head.

On the plastic body of the septic tank there are polypropylene pipes with a diameter of 11 cm, designed to connect the inlet and outlet sewer PVC pipes. The branch pipe for connecting the inlet sewer is located at a distance of 1.2 m from the upper boundary of the tank, and the outlet pipe is at a distance of 1.4 m from the top.

Installation Benefits

"Kedr" - a septic tank made of materials resistant to corrosion. Its service life is more than 30 years. Energy independence can be considered one of the main advantages of this compact installation. In addition, an absolutely sealed and waterproof septic tank "Kedr" can be purchased at an affordable price. The installation provides several stages of wastewater treatment, as a result of which it is possible to achieve a fairly high level of filtration. In case of special need, special biological preparations can be added to the system, activating the processes occurring in the chambers.

"Kedr" is a septic tank that has a relatively compact size and therefore allows you to save on the rental of heavy equipment. Installation of the system is relatively simple, so if you have the desire and certain skills, you can do it yourself. In addition, the model does not take up much free space. The only thing it requires is a deep pit, which eliminates the need for tank insulation.

Septic tank design

The septic tank "Kedr" is a sealed container made of polypropylene.

It differs from conventional sedimentation tanks intended for collecting wastewater by the presence of several functional chambers:

The device of the septic tank "Cedar"

1. Drains enter the first chamber by gravity. Therefore, the septic tank is located lower than the pipeline so that the liquid mass moves under the influence of gravity. In the chamber, large particles of impurities settle to the bottom, and light fat molecules float to the surface, forming a film on the surface.
2. In the second chamber, a preparation of anaerobic bacteria is added, capable of carrying out their vital activity without air access. Waste water is partially clarified here.The amount of the added drug depends on the volume and degree of pollution of wastewater
3. The third chamber is a biological filter. All microflora lingers here, and effluents enter the next department. The filter requires periodic cleaning and replacement.
4. In the fourth compartment, the filtration process is completed, wastewater is clarified.

Consistently passing through several stages of treatment, the effluent is divided into fractions, and the solid mass is subjected to biological decomposition. Each of the chambers is isolated, contact with the external environment is excluded. The polypropylene case allows you to bury the container in the ground with a guarantee of tightness.

Technical characteristics of the septic tank "Cedar"

Distinctive features of a septic tank

Septic tank for cottages

Compared to analogues from other manufacturers, the design from Unilos has several advantages:

• Quick installation of a septic tank "Cedar". Installation is carried out in a pit of small diameter manually, without the use of heavy equipment.
• Sealed body. The contents of the container are isolated.
• Durability. The average service life of a polypropylene tank in the ground is 30 years. Plastic won't rot, rust or fade. During this time, the tightness of the installation is maintained.
• Acceptable cost. A septic tank is available to families with an average income.

Choosing the type of septic tank

All variations of septic tanks are divided into:

In the first case, the treatment plant is the simplest sealed reservoir for the accumulation of wastewater. For their subsequent pumping, a sewage machine is then used.

Storage tank "Rostok"

The second category includes cesspools with a draining bottom, as well as septic tanks with anaerobic bacteria, an internal cleaning depth of up to 85% and an additional infiltrator.

Two-chamber septic tank "Tank"

The third option is full-fledged stations that process sewage by 95-99%. At the outlet of them, the water has a technical condition, which allows it to be used for watering the garden in the country or washing the car in the garage near the house.

Autonomous cleaning station "Topas"

Accumulators and most of the anaerobic septic tanks are non-volatile structures. They do not have pumps and compressors, all water flows inside occur by gravity. They do not require electricity to operate. If the water supply for a country house is organized from a well or centrally, then this option is just perfect for a cottage.

Aerobic septic tanks are stations that depend on uninterrupted power supply. They have better effluent treatment rates. But the aerators pumping air into the chamber with activated sludge need constant power from the electrical network.

For summer cottages, it is best to choose a septic tank of the first or second type. Such VOCs are cheaper to manufacture, easier to maintain and do not depend on the power supply. But for full-fledged private houses outside the city, it is worth choosing an aerobic station. A large family of effluents produces a lot; a cesspool or an anaerobic plant will not be able to cope with significant daily volumes.

For the manufacture of septic tanks are used:

The best septic tanks for summer cottages are factory anaerobic models with a polyethylene casing. They effectively clean drains, take up little space and do not need electricity. Plus, you can put them right next to the country house

Moreover, it does not matter if the screw or pile-strip foundation is used for its construction.

Moisture from such VOC will not have a special effect on this base. Such a septic tank is airtight, and the infiltrator or drainage well can be taken away from the building. In such a situation, when building a house, it is even allowed to use gas silicate blocks, which really do not like high humidity.

Device

The septic tank, manufactured under the Kedr brand, is an installation that looks like a vertically oriented cylinder. The case is made of durable plastic and is absolutely sealed, so its installation cannot harm the environment.

The internal capacity is divided into sections, and each of the sections has a specific purpose.

What processes take place in the chambers?

Entering the septic tank through the pipeline, the effluents go through several stages of treatment:

• The receiving chamber is used to collect contaminated liquid. Here the drains settle. Under the influence of gravitational forces, the liquid is divided into several fractions, depending on the specific gravity;
• The precipitated solids are subjected to anaerobic decomposition, where the microorganisms contained in the effluents take part;

Water is discharged to filtration sites. If, due to high-lying groundwater, above-ground filtration cassettes are installed, then a pump is included in the system, with the help of which water from the septic tank is supplied to the cassette located higher in level.

Characteristics and dimensions

So far, only one modification of the Kedr septic tank has been produced, designed for operation in summer cottages or in small houses. Model characteristics:

• Case diameter - 1.4 meters;
• Hull height - 3 meters;
• Weight - 150 kg;
• The daily capacity of the model is 1000 liters.

Maintenance and application of biologics

Thanks to the right septic tank installation Cedar will not cause any difficulties. The accumulated sediment is periodically pumped out using a sewage machine. As a rule, this procedure is performed every 2 years. The removable biofilter is washed periodically. In some cases, it is rational to replace it. Medicines, as well as chlorine and various acids, should not be thrown into the sump, because microflora can die because of them

It is important to monitor the temperature of wastewater. The minimum is +5°C and the maximum is +50°C

Biological preparations can be used to increase the cleaning efficiency. Thanks to them, the waste will be processed faster, and the life of the sump will be extended. The UNIBAC bacteria complex is most commonly used. It is a preservative solution with liquid microgranules 0.1 mm in size. Microorganisms entering the sump begin to multiply and process waste. Since bacteria die during the cleaning process, it is necessary to periodically add a biological product. Its greatest activity is observed at temperatures from +18°C to +30°C.

It is believed that only biological treatment plants perform the best water purification. Naturally, such equipment is quite expensive and complex, so for suburban areas, the Kedr septic tank will be the best option. With its help, it will be possible to process wastewater with minimal costs.

Benefits of a Kedr septic tank

In such equipment, wastewater is treated in several stages. During such a process, the separation of fractions is carried out, as well as the gradual decomposition of waste. The presence of appropriate bacteria helps to activate this. Their number directly depends on the volume of the tank and the received effluents.

The main advantages of a septic tank are:

• ease of installation;
• possibility of installation in a small pit;
• there is no need to use special equipment;
• tightness of equipment;
• corrosion resistance due to the creation of a tank made of durable plastic;
• the ability to install at a distance of 5 m or more from the house;
• durability;
• affordable price.

Thanks to the use of the Cedar septic tank, additional cleaning will not be needed soon. The sediment is removed on average once every 2 years. The equipment itself is highly efficient. It is suitable for a family of 4-5 people. Separately, it is worth mentioning the fact that the container is below the freezing level of the soil, which means that additional insulation is not required.

Naturally, such equipment has minor disadvantages. The septic tank needs to be cleaned periodically. For this purpose, a drainage trench should be organized, which can cause some difficulties.

Device and principle of operation

The septic tank is a sealed monoblock unit made of the strongest polypropylene, consisting of four compartments. The height of the structure is 3m, the diameter is 1.4m. The weight of the septic tank is 150 kg. Some models may have a higher or lower head.

In each chamber there is an individual stage of biological treatment. Waste flows from compartment to compartment by gravity thanks to a system of nozzles that are part of the product package.The operation of a septic tank is based on two types of processing and cleaning - mechanical and biological, and is carried out according to the following scheme:

1. Acceptance and separation of impurities. Wastewater from the premises through the sewer pipes enters the first chamber. Here, the waste is divided into fractions: heavy and solid accumulate at the bottom, and light ones form a film on the surface. When the first chamber is full, the waste flows through the overflow into the second compartment.
2. Lightening. The effluents that have entered the second chamber continue to settle to the bottom. Here begins the activity of anaerobic bacteria, which decompose organic waste in an airless environment.
3. mechanical filtration. The third compartment is a replaceable biofilter, which is inhabited by colonies of bacteria. Here, the process of decomposition of organic matter continues more intensively, and the effluents are subjected to additional filtration.
4. Accumulation and retention. In the last, fourth, effluent chamber comes cleaned by 75%. It is from here that they are brought to aeration fields or to a container where they will be stored until they are used as process water. To raise the level of discharge of purified water in the fourth compartment, you can install a drain pump with a float. The options for diverting treated wastewater depend on the hydrogeological features of the site.
