The principle of operation of a septic tank and a device in a private house on the example of the basic models

Septic Tank, which has traditionally settle in the territory, a thing of the past.To avoid contamination of the soil, draining it should not exceed the volume of 1 m³ / day.But this is unrealistic, because in the modern private house, by definition, have a bathroom and toilet rooms, and in addition, some household appliances, in which water is used (for example, machine washing and dishwasher).

Therefore, septic tank, no matter what design it was - the only acceptable solution in the organization of the sewer system.To select the optimal variant of the device of a large number of different models, it is necessary to know how the septic tank, its structure and operation.Here are this and face it.

Species septic

In execution

Quite often septic tank mounted on their own, picking out individual components (for example, concrete rings).Typically, a one compartment, which simultaneously serves as a settling tank and filter.This option does not provide a proper degree of purification, so it is suitable except for the suburban area, but not for high-grade residential buildings.Installation is more complicated design, especially in the home, not only requires skilled hands, but also specific engineering training.

In connection

By type of post-treatment

Components septic

sump - the first camera. It receives effluent from sewage pipes.Its purpose - to separate suspended solids from liquids (preliminary, rough treatment).Heavy oils are gradually deposited on the bottom (the process takes place within a few days), and fluid gradually flows into the next compartment.Filter

- 2 and 3 of the camera. They performed post-treatment of wastewater.There are several different process - biological.It involves the bacteria that decompose finally remaining slurry.

drain well (camera). execution of this part of the septic tank depends on the particular model.It serves to ensure the removal of clarified liquid from the territory.As an option - for the removal of the 2-chamber septic tank liquid is arranged (if allows the size and layout of the territory) of the filter box.If it is not possible to equip, put Infiltrator from which purified water goes into the ground.

Advanced - vent tube (to drain the resulting gases) and the hatch through which the inner tank is cleaned.

types of septic tanks

single chamber

One of the models (from w / w of the Rings) is shown in Fig.

analogue of plastic works on the same principle.

Double chamber

Such models are well suited to small private homes if there is withdrawal from the territory.

drainage organize directly on the site is undesirable as the quality of cleaning is not very high, and there is a risk of groundwater contamination.This is especially significant if the water withdrawal is made from a well or wells in limestone (less than 10 m depth).

three-compartment

Provides the best possible wastewater treatment.

operating principle is easy to understand the schemes.

Here, perhaps, and everything you need to know about the principle of operation of a septic tank.This information will help determine the most appropriate option for the cleaner of your own home.Visually all work processes septic tank shown in the video:

Note!The most popular models of septic tanks in the private sector - "Tapas" (described here) and "Tank" (description here).They are characterized by variety of assortment, affordable prices, ease of installation and maintenance.In principle, these are the main criteria for selection of cleaning devices.
