Septic "Evostok" - care for the sanitary condition and ecological purity

People living in private homes often face the problem of sewage. In this matter, it is important not only to properly communicate, but also carefully select special equipment.

If the owners of the house do not want to live in unsanitary conditions, it is recommended to pay attention to the septic tank "Evostok". Septic (the choice of devices is represented by several models) of domestic production, still not popular among consumers. However, this does not mean that this device is of poor quality. Its undisputed advantage is dual-mode operation. Firstly, it can function as a normal septic tank, and secondly it can provide a deep biological treatment of sewage. The latter method guarantees the content of impurities in water no more than 5%. After cleaning, it can be used to irrigate gardens.

What is the septic of the trade mark "Evostok"?

Septic "Evostok" - a system of autonomous sewerage. It consists of three chambers made of polypropylene. Wall thickness not less than 8 mm. All material is processed by special technology, therefore it has a high level of strength and protection against ultraviolet radiation. Sewage passes through the three chambers spontaneously, step by step, during which an oxygen-free process of fermentation takes place. As a consequence, the precipitate is subjected to some degree of hydrolysis. After the waste water has passed through the entire system, all solids are disconnected from the liquid and it is discharged to the filtration fields where it is possible to organize a post-treatment process using aerobic bacteria.

If there is no possibility of additional processing, it is recommended to buy a septic tank "Evostok Bio". The testimonies of people who already use such a device show that the effluents at the outlet are completely clean, and this, in turn, allows them to be used again, for example, for irrigation. Such results are obtained due to the established biofilter.

Advantages of the septic tank "Evostok"

Along with a large assortment of expensive products of imported production, the domestic septic tank "Evostok" stands out favorably. It is not inferior in quality and functionality, but the pricing policy varies considerably. Consider its most significant advantages:

1. High strength of the case.
2. Energy independence, low maintenance costs.
3. Ease of maintenance. All that is necessary, call at least once a year a sewage machine.
4. A single clogged three-section polypropylene housing, which eliminates the possibility of penetration of waste water into the ground.
5. High level of productivity up to 2000 l / day.
6. It can be installed in houses where 1-10 people permanently reside.

Device unit

As already mentioned, the septic tank "Evostok" has three compartments. The first is combined with the drain pipe and with the second section through the damper. Further through the hydraulic dam the second compartment is connected to the third one.

In the first section, primary purification takes place with precipitation of heavier particles. The second one is used for a clarifier of partially clarified waters. The final section is the role of the final wastewater purifier. Here there is a final precipitation of suspended particles.

After passing through three compartments, the effluents are sent to the ground after-treatment. This can be avoided by installing the septic tank "Evostok Bio". It includes a biofilter, which completely delays all substances. Here in all three zones there is not only mechanical cleaning, but also biological cleaning. Why use oxygen-free bacteria. They effectively clean up drains in a climate of shortage of air.

For effective operation of this device, it is necessary to insulate the upper part of the device. This is especially true if the unit is designed for year-round use, including at negative ambient temperatures.

Cleaning steps

Sewage from the house goes to the first compartment through a pipe. It is installed at a certain angle to prevent clogging.

As a result of a shortage of water in the first compartment, purification processes occur in 2 stages:

1. Sour fermentation. Here organic waste is decomposed to a number of the simplest fatty acids, as well as to alcohols, H ₂ S, ammonium and CO ₂ .
2. Methane decomposition. The compounds formed at the first stage are decomposed into hydrogen, carbon dioxide and methane.

Important: the shutter apertures are located below the upper level of the drains, but above the sediment.

In the second zone, additional aerobic processes occur to maximize the effluent purification before entering the next chamber. Further through the bypass, the drains are sent to the last sewerage compartment, where the organic waste is deposited.

Septic "Evostok" is an effective and reliable method for cleaning sewerage, as evidenced by the feedback of numerous buyers.
