Septic tank "Uponor": device, advantages and disadvantages, review of the model range

A well-known Finnish manufacturer of sanitary equipment produces high-quality cleaning systems.The model range is represented by both filtration systems and biological action stations.

Each of them is made of high quality materials taking into account the climate of sulfur countries. A wide range of models allows you to choose an Onor septic tank that meets the buyer’s needs.

In this material we will talk about the design and operating principles of Onor septic tanks and give a brief overview of models with various types of wastewater treatment.

Installation of septic systems "Uponor"

The functionality directly depends on which model line the septic system belongs to. A common feature of the design of Onor septic tanks is the use of high-quality, high-strength and frost-resistant plastic.

Another feature is the anchor system. It consists of plastic weights fastened in pairs with cables.

Fixation is achieved due to the mass of soil, which prevents the plates from moving. They are thrown over the containers and fix them. This is necessary to prevent the septic tank from moving when groundwater rises. This displacement inevitably leads to deformation of the pipes and pipes of the drainage system.

Complete set of the Onor Sako model range

The advantage of these models is that there is no need for electricity. Septic tanks with Ononor Sako filtration system have a certain basic configuration.

These are one or more plastic tanks connected by overflow pipes. The containers are solid.The overflow pipes are removable, which allows them to be easily replaced if necessary in case of mechanical or other damage.

The resistance of the material from which the housing is made to low temperatures allows it to be installed on frosty days. The presence of telescopic removable necks of containers is very convenient; they reduce the volume when transporting a septic tank or cleaning station

Additionally, the kit includes a distribution well. Its function is to uniformly distribute the flow of filtered water through the aeration pipes. It can be used to reduce the volume of water passage on landscapes with a high slope.

The filtration field consists of perforated pipes that are installed in a bed of gravel and sand. Passing through the drainage, wastewater goes into the ground, where it is subsequently purified. The number of perforated aeration pipes (1-6) directly depends on the performance and volume of the septic tank.

The use of a distribution well allows the flow to be divided evenly through the drainage pipes of the filtration field. In addition, through it you can monitor the quality of water before it enters the ground through filtration fields.

It performs the functions of uniformly distributing purified liquid through several aeration pipes. At the same time, it also serves as an inspection well for monitoring the quality of cleaning. It contains a flow regulator, which allows you to control the pressure of the outgoing wastewater.

Corrugated pipes are laid from the septic tank tanks to the distribution well. They also serve as a connection between the distribution well and the perforated pipes.Also included are plugs, manhole top covers and filtration fabric.

Disposal of the liquid part of wastewater processed in a septic tank is carried out through a filtration field - a system of perforated pipes laid in the ground

The cleaning process in Onor Sako septic tanks is similar to overflow wells. However, there is a difference in the design and operation of the system. In it, wastewater treatment takes place in two stages.

At the first stage, all large fractions of wastewater settle at the bottom of three settling tanks. At the second stage, the water that has passed through all the containers is subjected to additional purification through filtration fields.

Most of the sludge accumulates in the settling tank. It is this that needs to be pumped out using the services of sewer trucks. Do not completely empty the container, otherwise the naturally accumulated decomposition bacteria will be removed. To preserve them, it is necessary to leave a small amount of sludge at the bottom of the tank

The step-by-step process for cleaning sewage is as follows:

1. After the wastewater is discharged into the sewer, it moves through pipes into the first connecting tank. Here large fractions settle to the bottom.
2. The liquid, freed from the insoluble inclusions that have settled to the bottom, but with the presence of fine suspension, flows into the second communicating tank. Here the process of water settling is repeated.
3. If the modification provides for the presence of three containers, then water also settles in the third.
4. Next, the purified water with a small amount of impurities goes into the distribution well, from where it evenly flows into the perforated pipes.
5. From the holes, water enters the dumped bed, where they are further purified by natural filtration in the soil.

If you install an additional filtration module - an infiltrator, which is an underground system for discharging treated wastewater into a ditch, post-treatment is carried out in it.

Infiltrator like filtration field or absorption well can be used only if there is at least 1 m between the conditional bottom of the systems and the highest groundwater level in the area.

The advantage of this system is that purified water can be used for household needs in a personal plot. To do this, you need to install a container where the purified water will be drained.

Complete set of the Onor Bio model range

Uponor Bio systems have excellent cleaning quality. Their use is permitted in protected areas. They are compact and require less space to accommodate. It works autonomously, but requires electricity to do this.

The equipment for all Onor Bio septic tanks is also identical for the entire model line. The anchor system is also not included in the basic package.

The stations use a triple cleaning system. Finnish legislation provides for restrictions on the presence of phosphates in wastewater, therefore, in addition to sedimentation and bacterial treatment, chemical substances are used to break them down

The package includes a molded tank divided into three compartments or three interconnected containers. The system of internal pipes and pumps is located in tanks and does not need to be installed. It is enough to connect the pipes for the passage of waste. Additionally, the kit includes equipment that consists of pumps and control modules.

Thanks to electronics, the system is able to exist independently and maintain the activity of microorganisms in case of inactivity for no more than three months. All system control is carried out remotely. In addition, the kit includes 15-liter tanks into which reagents and special bacterial compounds are poured.

The tanks are equipped with a system for feeding small portions of the contents into the settling tank. Additionally, you can order a well for sampling wastewater for biochemical research.

The wastewater flowing through the sewer line into the receiving tank of the septic tank undergoes triple purification. For clarity, each stage is presented with illustrations.

Once in the first tank, the wastewater settles. Then silt sediment occurs. Large fractions remain in the sedimentation tank, and the settled water enters the connected tank

There the process of settling the wastewater is repeated. After repeated precipitation, the top layer of purified water is moved to the process tank.

The second stage of water purification takes place in the process tank. A filling sensor is installed in the container. When a fixed level is reached, the air supply mechanism is turned on. The compressor supplies gas to crush the remaining solid sludge residue that falls to the bottom of the process tank

Next, the system waits the necessary time for the sludge to settle at the bottom of the process tank. After a few hours, sludge settles out, and the third stage of wastewater treatment occurs. It uses chemicals.

The chemicals are dosed. Its quantity is determined by the program embedded in the control module. Special additives neutralize harmful chemicals.At the same time, wastewater is disinfected. After chemical treatment, sludge residues settle at the bottom of the process tank

Next, sludge sediment is pumped out from the bottom of the tank.

Using an airlift, sludge from the bottom of the tank is moved to the sedimentation tank. As the container fills, it must be pumped out.

Purified water is removed when the tank is filled, through a pipe at the top of the tank. After this, it is transported through a pipeline to a drainage ditch.

Additionally, a drug containing anaerobic bacteria, since the amount of air in biological purification systems is reduced to a minimum. This will further increase the degree of wastewater purification and eliminate grease deposits on the walls of the tank.

Review of septic system models

To choose the right septic system, you need to follow a few basic rules. If the status of the territory on which the site is located falls under environmental legislation, it is necessary to choose systems with a biological type of treatment.

If the site does not have the status of a conservation area, the septic system must be selected based on the area. If it allows you to install a filter field, you can choose filtration systems.

Another factor to consider is the groundwater level at the site. If it is high, it is necessary to give preference to biological treatment systems. Having decided on the type of system, you can proceed to choosing a model. It must be selected according to the number of people living. It's better to take extra.

Filtration type of cleaning

The Sako model line is represented by the following modifications:

Care and instructions for use

In order to ensure proper functioning and extend the life of the product, it is necessary to promptly clean the sedimentation tanks of septic systems. This also applies to biological treatment plants. If you do not pump out the sludge from the bottom of the tank, over time it becomes more viscous and compresses.

In this case, a hard crust may form on the surface. Special biological preparations help combat these problems, which can arise from untimely pumping.

Uponor Sako septic tank models require special preparations that clear the openings of the spray pipes from clogging. To do this, it is necessary to use biochemical preparations. They extend the life of the filtration field.

Uponor Bio septic tank models require the use of chemicals. Third-party products may be used. The main criterion should be the ability to break down and process phosphates. This concludes the process of caring for Onor septic systems.

Advantages and disadvantages of Ononor systems

At first glance, the Sako model range does not differ from more affordable Russian-made analogues, but this is not so. It is impossible to find a septic system of the same shape as Uponor.

The spherical shape makes the container more resistant to water and soil pressure. In combination with high-quality plastic, an increase in the service life of the product is achieved. The disadvantages include the high cost of the product. In addition, some models need to be insulated.

The model range of septic tanks "Uponor" of the "Bio" series has its disadvantages and advantages. The advantages include high-quality cleaning. Not every system has a purification percentage of 98%.

The indisputable advantage of the system is the controls and sensors that transmit signals about the state of the system. Disadvantages include the need for electricity. The installation can be powered from the house by connecting a cable, or you can install a solar panel with a battery.

Another disadvantage is the cost of maintaining Bio systems. They need special chemicals to improve wastewater treatment.

The very design of the models eliminates the need to dig out the container, since all technical mechanisms are located in such a way that they can be easily replaced if necessary. In addition, the disadvantages include the warranty period for the control module. It is only two years.
