People living in private homes often face the problem of sewage. In this matter, it is important not only to conduct communications correctly, but also to 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 "Ewestock". Septic (the choice of devices is represented by several models) of domestic production, is still not popular among consumers. However, this does not mean that this unit is of poor quality. Its indisputable advantage is dual-mode operation. Firstly, it can function like a regular septic tank, and secondly, it can provide deep biological treatment of sewage. The latter method guarantees an impurity content of not more than 5% in water. After cleaning, it can be used to water gardens.
What is a septic tank of the Ewost trademark?
Septic tank "Ewate" - a system of autonomous sewage. It consists of three chambers made of polypropylene. Wall thickness not less than 8 mm. All material is processed using special technology, therefore it has a high level of strength and protection against ultraviolet radiation. Wastewater passes spontaneously through the three chambers spontaneously, during which an oxygen-free fermentation process occurs. As a result, the precipitate is hydrolyzed to some extent. After the wastewater 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 the post-treatment process using aerobic bacteria.
If it is not possible to carry out additional processing, it is recommended to purchase a septic tank "Ewost Bio". The reviews of people who already use such a device indicate that the effluents at the outlet are completely clean, and this, in turn, allows you to use them again, for example, for irrigation. Such results are obtained thanks to the installed biofilter.
Advantages of the septic tank
Along with a large assortment of expensive imported products, the domestic septic tank Evostok stands out. It is absolutely not inferior in quality and functionality, but the pricing policy varies significantly. Consider its most significant advantages:
- High durability of the case.
- Energy independence, low maintenance costs.
- Ease of maintenance. All that is necessary is to call a sewage machine at least once a year.
- A single corked three-section polypropylene housing, which eliminates the likelihood of sewage entering the soil.
- High level of productivity up to 2000 l / day.
- It can be installed in houses in which 1-10 people live permanently.
Device device
As already mentioned, the septic tank "Ewate" has three compartments. The first is combined with the sewer and with the second section through the damper. Then, through the hydraulic damper, the second compartment is connected to the third.
In the first section, primary cleaning occurs with the precipitation of heavier particles. The second - is used for the sump of partially clarified waters. The role of the final sewage purifier is implemented by the last section. Here is the final precipitation of suspended particles.
After passing through the three compartments, the effluent is directed to soil post-treatment. This can be avoided by installing a septic tank “Ewok Bio”. Its package includes a biofilter, which completely retains all substances. Here, in all three zones, not only mechanical cleaning takes place, but also biological treatment. What are oxygen-free bacteria used for? They effectively clean drains in conditions of lack of air.
For the effective operation of this device, the upper part of the device should be insulated. This is especially true if the installation is designed for year-round use, including at low ambient temperatures.
Cleaning steps
Sewer drains from the house are sent to the first compartment through the pipe. It is installed at a certain angle to prevent clogging.
As a result of a lack of water in the first compartment there are cleaning processes in 2 stages:
- Sour fermentation. Here organic waste is decomposed to a number of simplest fatty acids, as well as to alcohols, H 2 S, ammonium and CO 2 .
- Methane decomposition. The compounds created in the first stage decompose into hydrogen, carbon dioxide, and methane.
Important: the gate openings are located below the upper level of the drains, but above the sediment.
In the second zone, additional aerobic processes take place to maximize the purification of effluents before entering the next chamber. Then, through the bypass, the effluents are sent to the last compartment of the sewer, where organic waste is deposited.
Septic tank "Ewate" - a fairly effective and reliable way to clean the sewer, as evidenced by the reviews of numerous buyers.
