Nobody even thought of us what aeration is of great importance to humanity. What it is? Aeration - these are certain actions, as a result of which the oxygen deficiency in a given medium is compensated. Paradoxically, very small amounts of fresh air can do wonders for any living creature. In this article, we will consider in more detail what aeration is in some processes arranged by a person.
Natural aeration system
In general terms, the term aeration refers to the purification and saturation with oxygen (air) of any physical body (water, soil, etc.). This process is always accompanied by bilateral diffusion. First, air penetrates through the surface into the body and immediately derivatives of the substance also escape through its surface.
Under natural conditions, aeration is air exchange in multisurface strata of the soil, in open water bodies, in waterfalls. Man, as a creature that adjusts everything to fit his subject, could not resist in order not to take advantage of such a process for his own benefit, therefore aeration is much more common in industry. The most global application of aeration is wastewater treatment.
Wastewater treatment, aeration function in this process
Today, the aeration station is determined by experts as the most harmless and modern installation in terms of ecology. As a result of the aeration process, water is saturated with enough air, the oxidation process starts, and then all the organic components of the water decay. Thanks to special aeration devices, all the described actions proceed under artificial conditions and are much faster and more effective than in the environment.
As a power supply, such stations consume electricity, due to which a constant movement of air is established, which means that bacteria living in water, which are fed with oxygen, are provided with normal vital functions. They are just engaged in the oxidation of organic compounds in water, and the formation of fertile sludge.
Thus, microorganisms that feed on oxygen, in addition to water purifiers, become active inhabitants of environmentally friendly fertilizers.
When using this system, one should not forget about the aeration field and its proper arrangement.
Drinking water treatment with aeration
Wastewater is not the only one of its kind that is cleaned with aeration. Since aeration is still a natural process, it is also used to purify household water. Today, especially urban drinking water contains impurities of manganese, iron and hydrogen sulfide. All of them carry a danger to human health, so if you want to use really clean and safe water, then you can not do without reliable cleaning systems. It is aeration of water that underlies a variety of filter systems.
The essence of the cleaning itself can be stated in such phased steps:
- Water, saturated with oxygen, oxidizes divalent iron, which its composition is so rich in, to the state of ferric. Therefore, as a result of the reaction, iron precipitates and remains on the filter.
- At the same time, a second process takes place - blowing off hydrogen sulfide and other gases in a dissolved state.
The result is pure water that is completely suitable for drinking. This process is the most effective, and most importantly, such systems do not require the introduction of chemicals, and this, in turn, adds safety and efficiency to them.
Methods for aeration of drinking water
Today, depending on the pressure and other conditions, the following methods of aeration are distinguished:
- Pressure aeration is permissible with a good level of pressure and pressure in the line, while the concentration of dissolved iron should be no more than 15 mg / l. At the beginning, water enters the aeration column under a certain pressure, the flow sensor is triggered and the compressor for air injection is turned on. The water stream is enriched with oxygen, and then enters the filter.
- Non-pressure aeration is carried out at a lower pressure of water and at a high concentration of iron (more than 15 mg / l). This method is characterized by the presence of an additional tank in the installation. At the beginning, water is supplied to the tank, sprayed through special nozzles. The compressor, as in the previous embodiment, provides oxygen enrichment. Then water is pumped to the filter using a pump.
Aeration as an integral part of lawn care
In the above text, we considered aeration of water, but, as you know, aeration can occur in any environment. It's time to familiarize yourself with the process of soil aeration. The most suitable option is aeration of the lawn.
This procedure is necessary to create a fruitful atmosphere for the lawn. Indeed, over time, soil self-compaction occurs, and there can be many reasons for this (physical activity or an unconscious change in the landscape and others), and it is impossible to influence them, it remains only to deal with their consequences.
Compaction of the soil leads to a reduction in oxygen, as a result of which the roots receive less nutrients, moreover, the carbon dioxide that accumulates prevents the growth of grass cover. Aeration in the soil is a small calcination, as a result, holes should be formed through which air and moisture exchange pass.
How to aerate your own lawn
In this matter, it all depends on the size of the existing lawn. In the case of modest sizes, aeration with your own hands will be very useful. And you can do this by acquiring an ordinary tool - pitchforks. But if, proceeding from the large size, it will be difficult to do this, you can use special equipment for both manual and mechanical action. And these devices began to be called accordingly - aerators. Both models do not differ in the quality of the work done. But, it is indisputable that a more effective aeration will occur in wet soil, since dry soil prevents the normal penetration of the aerator.
When should aeration of the lawn
The motive for the process of aeration of the lawn should serve as a long drought or, conversely, multi-day heavy rain. Only with drought, aeration of the lawn will facilitate the transport of water to the roots of the lawn grass during irrigation, and in the second case, the drainage of excess moisture to prevent grass decay.
Immediately before the start of aeration, if it is carried out by aerators, you need to make sure that there are no foreign objects (stones and branches) in the territory that needs to be processed.
How often should aeration of the lawn
In general, if puddles are still visible on your lawn after a little rain, you should know that this sign says that the lawn needs aeration. It will also be useful to the lawn, on which cars ride from time to time, it will help the grass to rise from the ground.
During systematic and systematic lawn care, aeration should be carried out after 3 lawn mowings. This frequency will take care of the cleanliness of your lawn from moss and weeds, and the damage to the coating itself will be minimized. But it is worth noting that soils with a high clay content and areas directly located near pedestrian roads require more careful attention.
After the first aeration, does your lawn look much better? Do not rush to rejoice, continue in the same spirit and in no case do not stop, because aeration is a longer and more laborious process, because you need to achieve not just short-term improvements, but a full recovery.
The role of oxygen in the aquarium
Aeration at a depth in natural conditions occurs as a result of shuffling water masses. Unfortunately, things are different in aquariums, so it’s important
A prerequisite for the normal functioning of the aquarium is to ensure the aeration process in it. The minimum value of oxygen content in the aquarium is 5 mg / l, but this value is considered the limit for breathing, but in no case for the normal functioning of the entire biological system.
Aeration of water in the aquarium contributes to oxygen saturation to the maximum, and in order for the incoming oxygen to be distributed equally throughout the volume, it is necessary to ensure intensive mixing of water masses and not only.
Mechanisms that provide aeration process in aquariums
Aeration of water in the aquarium can be carried out by several installations. Firstly, it can be a filtration system, arranged so as to circulate water to the maximum, or even better option - on the surface of the water. However, everything needs to know the measure. In general terms, filtration equipment should be systematically suitable for a given type of aquarium in terms of size and durability, and its installation should be made accordingly.
Secondly, aeration can also be obtained using a pump (miniature size compressor and atomizer). In this case, a stream of bubbles is obtained which contribute to the circulation process.
