For private buildings and industrial premises located outside the city, there are two main types of sanitary cleaning devices:
Septic tanks, they are called anaerobic systems. Such a system looks like a closed container, inside of which, thanks to special bacteria, the process of decomposition of sewage takes place.
Aerobic systems. The difference of this type of sewage is that the purified water enters the soil through a separate pipe.
Anaerobic treatment systems. These are tanks with the presence of a biofilter. In the septic tank are usually from one to six special filters. In the sewage system of a septic tank, primary disinfection is provided for and household waste is filtered.
Biofiltration, which occurs due to microorganisms living in an environment devoid of oxygen, follows the primary filtration. In a modern filter, cleaning takes place in tanks with a special powder, in which microorganisms do their work.
Anaerobic cleaning system filters about 75 percent of waste. For a suburban site, the anaerobic type of sewage system is twice cheaper than other sewer systems. One of the advantages is the ease of installation of the septic tank, and the ability to use the anaerobic system autonomously. Modern septic tank for installation does not require special knowledge and skills, it can be installed independently. Powder bacteria need to be updated every few years. For this type of sewer does not require a constant supply of electricity. Septic tanks are suitable for all types of country houses. The ideal place to install such a sewer is considered to be where the groundwater level is low.
The design of the aerobic sewage system is much more complicated and more expensive than a simple septic tank. This is justified by the fact that the waste water is 95% purified, which allows you to safely discharge such water into the soil. Wastewater is purified by microorganisms in an oxygen environment. One of the most common such sewage is sewage to the danger. The principle of work consists in careful and gradual sewage treatment. The operation of such a sewage treatment plant completely eliminates the appearance of unpleasant odors and emissions of the contents in the tank into the soil.
