In order to ensure effective wastewater treatment, three stages should be combined:
- mechanical sedimentation;
- fermentation under the influence of anaerobic bacteria;
- anaerobic decomposition of organic substances.
The first two stages take place in sealed chambers in the form of sedimentation tanks. As for aerobic decomposition, it requires the supply of oxygen. For these processes to occur, you should purchase a ready-made cleaning station or install a compressor. If you choose the second option, then it is important for you to decide which equipment to prefer.
Is an aerator necessary
The treatment plants that you can find in stores are usually equipped with compressors, the latter are devices that inject oxygen into the chambers and saturate the effluents with air. The supply of oxygen is required to ensure the living conditions of microorganisms, which are called aerobic and process organic impurities quickly and efficiently.
General information about aerators for sewage treatment plants
If you want to choose a compressor for a septic tank, you should know that not every similar device is suitable for this. Therefore, this issue must be approached seriously. If you make the choice in the direction of the wrong device, the septic tank will not be able to provide the proper level of cleaning, which will negatively affect the environment and the performance of the equipment.
It is necessary to select the unit taking into account the fact that it must withstand sewage and aggressive environmental factors. If this is not so, then the compressor equipment will require repair within a few days after the start of work.
Selection factors
A quality device is different:
- high degree of reliability;
- work without the formation of excess noise;
- resistance to corrosion;
- long term of operation.
In order to ensure the aeration process in the system, screw or membrane devices are used. Screw are also called diaphragm. Such equipment is structurally different.
When to choose a screw aerator
The compressor for a septic tank can be screw. The rotor in the amount of 2 pieces acts as the main working unit of this unit. This part of the device pumps oxygen inward. Among the main features of such devices should be highlighted:
- profitability;
- minimal compactness.
An additional plus should be considered the almost complete absence of noise during operation. Screw compressors can be classified into several more varieties. And if you plan to equip your home sewage system, then you should not choose a dry compression aerator and low-filled devices for it, because these units are large-sized and require regular professional maintenance.
When to choose membrane devices
Membrane compressors for septic tanks are quite common, easy to use and almost maintenance-free, and you will have to resort to repair very rarely. The principle of operation is based on the movement of the diaphragm or membrane, which contributes to the creation of pressure inside. The membrane is driven by a piston connected to the hydraulic actuator.
If you purchase high-quality equipment, then it can work for years. You can extend the life of the device with scheduled repairs. By purchasing a membrane aerator, you will need to change it every 2 years. If you live in an area with a hot climate, you should not prefer a membrane air compressor, because high air temperature can contribute to the drying of equipment.
Additionally, what kind of unit to purchase
When choosing a compressor for a septic tank, you should know that these units are necessary to increase the gas pressure, which occurs due to a decrease in its volume. Installations operating on this principle can be screw or piston. They differ among themselves by the principle of gas injection inside.
For example, piston pressure is provided by the movement of the pistons; as for screw, they work due to the block with the corresponding name. Some believe that it is worth choosing the second variety, because such devices are more compact, durable and have a low level of vibration.
Considering the piston devices in more detail, you can highlight one of their varieties - the electromagnetic membrane compressor for the septic tank. Such devices are also called diaphragm, they are designed for local sewage. Their main advantage is the ability to pump pressure at low productivity.
The principle of operation of such devices is as follows: making a reciprocating motion, the magnetic core moves in an electromagnetic field and drives the diaphragms, which are responsible for pumping air. On sale, you can also find dynamic models that provide air injection with an increase in its speed and conversion to outlet pressure.
Considering the dynamic apparatus, you can distinguish centrifugal, as they are found most often. They can be classified into axial and radial. These units are selected less often, since they are expensive, their operation is accompanied by a high noise level, in addition, they are quite bulky. Such aggregates are rarely considered as an aerator for a septic tank.
The best choice
In order to provide autonomous treatment of wastewater, which will be supplemented by post-treatment, it is better to choose a membrane apparatus. It is offered for sale in several models, which may have variations in mini-performance. The membrane mini-compressor is inexpensive, and runs silently. When choosing it, you should pay attention to the manufacturer, reviews and power of the unit.
If you are planning a local septic tank device, then for its aeration it is better to use a screw compressor, which is designed to work around the clock. A number of manufacturers of sewage treatment plants supplement them with such units. If you have to make a choice on your own, then it is not recommended to purchase screw compression dry aggregates, since they have many disadvantages.
Aerator for treatment plant brand "Topas"
The compressor for the Topas septic tank can be volumetric or dynamic. Such units operate due to electricity. Depending on the power, the devices can increase the functionality of the treatment plant, which is designed to serve a different number of people.
For a small plot and for a cottage village, aerators with different characteristics are required. A compressor for the Topas septic tank is not required after the acquisition of the system, because aerators are installed at the assembly stage. These septic tanks are equipped with membrane devices. But when the old device fails, you will have to purchase a new one.
In order not to make a mistake with the choice, it is better to contact specialists. When purchasing an air compressor, you should be prepared for the fact that it will affect the performance of the system. It is important to choose equipment that will not only not spend too much electricity, but also cope with the volume of wastewater.
When purchasing an air compressor for a septic tank, you should make sure that it does not have a reduced or increased power, as this can cause a decrease or increase in the flow of oxygen, which affects the behavior of bacteria. When choosing an aerator, you should pay attention to the manufacturer. The most popular and popular today are Japanese compressors Secoh and Hiblow. No less common are Korean Airmac appliances. These devices have many positive reviews and have proven themselves in the market.
