Aeration is oxygenation of something. Translated from the Greek language, aeration is "airing", "air saturation". For what purpose can gardeners use aeration?

Septic tank aerator

Any private home needs an efficient drainage system. A septic tank is used to purify waste masses in residential buildings.

All sedimentation tanks work on approximately the same principle. A septic tank is a sealed container into which dirty water and human waste enters and undergoes primary cleaning.

The septic tank can be constructed from concrete rings, welded from metal sheets or bought ready-made from plastic or fiberglass. These drives come in 1-2 or 3-chambers. Any septic tank is equipped with a special pipe through which carbon dioxide comes out. But for the vital activity of microorganisms, which have a beneficial effect on the purification of sewage, oxygen supply is required, therefore, it is necessary to equip the septic tank with additional equipment - an aerator. It is mounted at the bottom of a septic tank and oxygen is supplied using an air pump or compressor.

Septic tank aerator

There are two types of bacteria in a septic tank:

  • aerobic bacteria that need oxygen to live;
  • anaerobic bacteria that do not need oxygen. But they do not completely decompose organic compounds, and all processing processes are slow.

Important! Sediments should be equipped with a ventilation system, since bacteria emit various gases, and as a result, a bad smell appears.

The principle of operation of a septic tank aerator

The aerator is designed to distribute air in a liquid. The air is supplied by a membrane compressor. There are 2 types of these devices: tubular and disc. There are different types of aerators, but the most popular is fine. What is a tubular aerator and how does it work? This is a pipe covered entirely with small through holes. One pipe end is sealed, and the other is connected with a hose to the compressor. The compressor for the aerator supplies a certain amount of air, it passes through the pipe and through small through holes enters the liquid, where many oxygen bubbles are formed. According to Archimedes' law, oxygen rises up and, together with unpleasant odors, is thrown into the ventilation pipe.

Aerator

What is a disc aerator like Matala MD-225? This is such a device, made in the form of a disk and equipped with a membrane that allows oxygen to pass through. Membranes need to be replaced every 2 years. At the bottom of the aerator there is a tube through which air is supplied from the compressor. It passes through the membrane into the liquid to be cleaned and goes out into the ventilation together with harmful gases.

Important!Making an aerator for a septic tank with your own hands is not difficult if you understand the principle of its operation.

Sewer aerator

Pond aerator

For the normal operation of the sewer system, it is necessary to establish its ventilation. Without proper ventilation, over time, a bad smell will appear in the house. In order for the air exchange to be normal, you need to install a sewer aerator. What is it?

Due to this device, the pressure in the sewage system is equalized, and unpleasant odors that are discharged outside do not enter the house.

Sewer aerator

The principle of operation of the aerator for sewage

The device prevents unpleasant gases from getting back into the house, that is, it is such a check valve.Also, this valve eliminates the vacuum in the system that occurs if a large amount of water is discharged at the same time.

The design of the aerator is very simple. Its components:

  • body;
  • air intake valve;
  • regulating mechanism for opening and closing the diaphragm or stem.

Kinds

Aerator (vacuum valve)

There are two types of aerators:

  • Vacuum. These are small ball-type models with a diameter of 5 cm, which are installed in plumbing fixtures. If a vacuum occurs in the system, the ball overlaps the membrane. Such aerators are installed on a long sewer pipe.
  • Cylindrical. This link is mounted in the background pipe. In this case, the main element will be the spring-loaded membrane for the aerator.

Where else are aerators used?

Roofing aerator Technonikol

These devices are needed not only for sewage treatment plants, but also for air saturation of reservoirs, aquariums and other containers. They are also used to purify water in wells and boreholes, since the water supplied to the reservoir is not always of excellent quality. It may contain impurities of various metals and alkalis.

  • Submersible aerator for water tank... In winter, lakes and ponds are covered with ice. It is clear that oxygen starvation occurs in fish. To avoid this, there are submersible devices that enrich water with oxygen.
  • Well water aerator... It is believed that the water from the well is clean, but, unfortunately, this is not entirely true. It is often high in iron or hydrogen sulfide. To reduce them, as well as saturation of water with oxygen, water aeration is used.
  • Toilet aerator... A valve that prevents unpleasant odors from entering the living space from the sewer pipe is very necessary in the toilet room. It is mounted on top of a sewer pipe, and odors from the system do not enter the apartment.
  • Wastewater treatment plant aerator... With the help of this device, for example, the Polypor aerator, biochemical wastewater treatment in industry takes place.
  • Well aerator... This device cleans well water from iron impurities and other compounds. Under the influence of oxygen, oxidation of impurities occurs, and they precipitate, and the water in its chemical composition is brought back to normal.
  • Air aerator Is the same device that oxygenates aquariums. The components of such an aerator: pump, hose, spray.

A few more words about a septic tank for a summer residence. Very often, a private house is equipped with an outdoor toilet. Several years ago, cesspools were used, which was not very convenient (there was a smell, the soil was contaminated). Now you can either buy or make a special septic tank yourself. And if it is equipped with an aeration system, then this will become an undoubted advantage.

Thus, aeration is a necessary thing for a summer residence, without which there is nothing now. The process can be adjusted for the correct operation of the septic tank, outdoor toilet, pool and well. Having figured out the principle of the operation of the aerator, assembling the device according to the scheme with your own hands will not be difficult.
