Aeration is ... Aeration system

No one even thought of us how important aeration is for mankind. What it is? Aeration is a certain action, as a result of which oxygen deficiency is compensated in one or another medium. Paradoxically, very small amounts of fresh air can do wonders for any living being. In this article we will consider in more detail what is aeration in some processes, equipped with man.

The system of aeration in the natural environment

In general, 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 two-way diffusion. First, air penetrates through the surface into the body and immediately the derivatives of the substance also volatilize through its surface.

In natural conditions, aeration is the air exchange in the multi-surface layers of the soil, in the open water bodies, in waterfalls. Man as a creature that adjusts everything to his subject, could not resist to not take advantage of such a process for his own benefit, so in the industry aeration occurs much more often. The most global application of aeration is wastewater treatment.

Wastewater treatment, aeration function in this process

The aeration station for today by experts is determined by the most harmless and modern installation in terms of ecology. Due to the aeration process, water saturation with a sufficient amount of air, the oxidation process starts and the further decomposition of all organic components of water. Thanks to special aeration devices, all described actions take place in artificial conditions and are much faster and more efficient than in the environment.

As a food, such stations consume electricity, so that a constant movement of air is established, which means that bacteria living in water that feed on oxygen are provided with normal vital activity. They are just engaged in the oxidation of organic compounds in the water, and the formation of fertile silt. 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 field of aeration and its proper arrangement.

Purification of drinking water by aeration

Sewage is not the only one of its kind, which is purified by aeration. Since aeration is still a natural process, it is also used for cleaning household water. Today, especially urban drinking water contains impurities of manganese, iron and hydrogen sulfide. All of them are dangerous for human health, so if you want to use really clean and safe water, then you can not do without reliable cleaning systems. It is the aeration of water that underlies a variety of filter plants.

The essence of the purification itself can be stated in such step-by-step actions:

1. Water, saturated with oxygen, oxidizes the ferrous iron, which is so rich in its composition, to the state of the trivalent. Therefore, as a result of the reaction, iron precipitates and remains on the filter.
2. At the same time, a second process is taking place - blowing off hydrogen sulphide and other gases in a dissolved state.

As a result, pure water, completely suitable for drinking. This process is the most effective, and most importantly, such systems do not require the introduction of chemical reagents, and this, in turn, adds to their safety and economy.

Methods of aeration of drinking water

For today, depending on the strength of pressure and other conditions, the following methods of aeration are distinguished:

• Pressure aeration is acceptable at a good level of pressure and pressure in the pipeline, while the concentration of dissolved iron should not be more than 15 mg / l. In the beginning, the water enters the aeration column under a certain pressure, the flow sensor activates and the compressor turns on for air injection. The water stream is enriched with oxygen, and then it enters the filter.
• Non-pressure aeration is carried out at a lower water pressure 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 fed into the tank, sprayed through special jets. The compressor, as in the previous version, provides enrichment with oxygen. After that, the water is fed to the filter using a pump.

Aeration as an integral part of lawn care

In the above text we considered the aeration of water, but as you know, aeration can occur in any medium. It's time to get acquainted with the process of soil aeration. The most suitable option is the aeration of the lawn.

This procedure is necessary to create a fruitful atmosphere for the lawn. After all, the soil becomes self-compacting over time, and there can be a lot of reasons for it (physical activity or unconscious change in the landscape, etc.), and it is impossible to influence them, it is only to struggle with their consequences.

Soil compaction leads to a reduction in oxygen, as a result of which the roots will not receive nutrients, moreover, carbon dioxide, which accumulates, prevents the growth of the grass cover. In the soil, aeration is a small calcination, as a result, holes must be formed through which air exchange and moisture exchange take place.

How to aerate your own lawn

In this issue it all depends on the size of the available lawn. In the case of a modest size, aeration with their own hands will be very handy. And you can do this by acquiring an ordinary tool - pitchforks. But if, based on large sizes, it will be difficult to do this, you can use for this case a special technique of both manual and mechanical action. And these devices began to be called accordingly - aerators. The quality of the work done, both models do not differ. But, undoubtedly, more effective aeration will occur with moist soil, since dry ground prevents normal penetration of the aerator.

When should a lawn be aerated

The motive to the process of aeration of the lawn should be a prolonged drought or, conversely, a multi-day torrential rain. Only with drought aeration of the lawn will facilitate the transportation of water to the roots of lawn grass during irrigation, and in the second case - drainage of excess moisture to prevent the rotting of grass.

Immediately before the start of the 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 must be treated.

How often should a lawn be aerated

In general, if after the end of a little rain on your lawn for a certain time, puddles are noticeable, you know, this sign says that the lawn needs aeration. It will also be useful to the lawn, which from time to time the cars ride, it will help the grass to rise from the ground. During systematic and systematic care of the lawn aeration should be carried out after 3 haircuts of the lawn. This periodicity 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 more careful attention is required to the soil with a high content of clay and areas directly adjacent to the pedestrian roads.

After the first aeration your lawn looks much better? Do not rush to rejoice, continue in the same spirit and in no case do not stop, because aeration is a process that is more time-consuming and laborious, because you need to achieve not a short-term improvement, but a full recovery.

The role of oxygen in the aquarium

Aeration at a depth in natural conditions occurs as a result of shuffling of water masses. Unfortunately, in aquariums things are different, so important A condition for the normal life of the aquarium is to ensure in it the process of aeration. The minimum value of the oxygen content in the aquarium is 5 mg / l, but this value is considered the limit for respiration, but in no case for the normal functioning of the entire biological system.

Aeration of water in the aquarium promotes saturation with oxygen to the maximum, and in order that the incoming oxygen is distributed equally throughout the volume, it is necessary to ensure intensive mixing of water masses and not only.

Mechanisms that provide the process of aeration in aquariums

Aeration of water in the aquarium can be carried out by several installations. First, it can be a filtration system, arranged to circulate water to the maximum, or even the best option - on the surface of the water. However, everything needs to know the measure. And in general, the filtration equipment should be systematically suited for this type of aquarium in terms of size and durability, and its installation should be carried out accordingly.

Secondly, aeration can be obtained with a pump (a miniature compressor and a nebulizer). In this case, a stream of bubbles is produced that facilitates the circulation process.

Factors affecting oxygen saturation

• The water temperature plays a key role for all the ongoing processes in the aquarium, regardless of their nature. And, of course, the value of this value is taken into account when calculating the saturation level with oxygen. The higher the temperature of water, the oxygen supply will be worse.
• The size of the bubbles coming from the nebulizer also matters. The smaller their size, the better. It has been scientifically proven that small bubbles (0.1 mm in diameter) oxygenate the aquarium at 10 g / m ³ , while aeration of the aquarium with a larger bubble diameter (2 mm) reduces this value by half. And the measurements were made at the same depth.
• But not only aeration provides the water with oxygen, the same action is taken by the plants that are there, because the process of photosynthesis has not been canceled. Also, some amount of oxygen enters the aquarium from the atmospheric.
• Another condition that affects the amount of oxygen is organic substances (the remains of feed, the products of vital activity and the excrement of fish) that are in the aquarium.
• The number of fish and other living things, the illuminance of the aquarium and so on.

This is not the entire list of ways to use aeration by a person for their own good. Apparently, the field of application is quite diverse and multifaceted, but scientists believe that the use of aeration is one single human action that in no way harms nature.
