Breathing is the source of life, not only for people, but for all animals. It is known that even plants that, due to photosynthesis, emit oxygen, at night, when there is no sunlight, they breathe, that is, they consume oxygen. Oxygen is needed not only by those on the surface, but also by those who dwell under water. Therefore, it is important to know how to make a pond aerator for yourself.
Water may stagnate in ponds
In natural conditions, where ponds flow into one another, water is saturated with oxygen. Continuously spouting sources replenish reservoirs with microelements. But ponds may require forced aeration. The need for this is due to several reasons:
The fish may not have enough air
In order to determine if your If you need to install an aerator, it is enough to watch a little about what is happening in the pond:
Design scheme of the aerator
If you have defined that it is necessary to urgently save livestock in your pond, then special devices that allow you to do this - aerators, come to the rescue. They are divided into two large groups:
The first ones are mounted and used constantly. The second option can be applied on several reservoirs. There are aerators and ways of location.
Surface. These include units that move freely around the surface of the water. Their principle of operation can be gushing. The pump draws water into itself and throws it out as a geyser above the surface. Water, being in the air, is saturated with oxygen, ionized. When water gets back to the pond, it passes the air to the inhabitants of the pond. In other embodiments, an ejector method of aeration is used. In the design of such a device, an engine with blades can be provided, which, striking the surface with great force and speed, lead to the formation of air bubbles and mixing layers. In other cases, a pump is used that draws water into itself, mixes it with air and returns it back to the pond.
Bottom or shore. This species is the most effective. The principle of its work comes down to the fact that there is a compressor on the shore near the reservoir. Its purpose is to supply air through pipes to special diffusers, which are mounted in several places at the bottom of the pond. Passing through the bubbles, the bubbles saturate the entire water column with oxygen, and the layers are mixed and the sludge is raised for further filtration. In order to prevent the reverse flow of fluid and its ingress into an electrical device, a valve is installed.
Combined. Most often they are classified as superficial. Here, as in the previous version, there is a compressor unit, which is located on the coast, it supplies compressed air, which is dispersed into the upper layers of water through a floating head. In another embodiment, the pump is installed. Through the moving module, water is taken, it is mixed with air and fed back from the shore in the form of a fountain or waterfall.
Wind aerators. Represent a floating or mounted on a support structure. The wind drives the blades, which transfer the torque to the underwater part, it creates a current, as a result of which air bubbles form on the surface.
It is not always worthwhile to dwell on the version that you personally liked.It is necessary to take into account the characteristics and needs of the inhabitants of the pond, including plants. Some of them do not like noisy falling jets, so you have to take care of the bottom options.
In most cases, you can save without buying a finished device. Enough to look around in your garage, and you may find that you have all or part of the necessary components for self-assembly. First, we will assemble an ejector type aerator. To do this, we need:
You need a drainage pump
The pump does not need to take the most expensive and powerful, in this just not necessary. The cross section of the cable for laying the flow line is selected in such a way that the power of the consumed current is maintained with constant operation. Assembly does not take much time.
If you wish, you can make some changes that will improve the performance of the aerator. To do this, you need to replace the angle connection from the pump with a straight pipe, also in the pipe that is on the surface, you can install a non-return valve with a soft spring. So the reverse current will not occur.
Perhaps the question arose, why can't a tee with an angle of 90 ° be used? In fact, everything is very simple - at an angle of 45 °, the air is drawn in and moves with the flow, mixing with water. If we take a tee with an angle of 90 °, there is a high probability of air reversal.
Self-priming centrifugal pump
The following possible method of manufacturing an aerator is not only useful, but and improve the aesthetic look. We will need:
The operation scheme of the aerator from a centrifugal pump
The number and diameter of fittings is selected depending on specific landscape solutions, as well as in accordance with the diameter of the pipes. The sequence of work is as follows:
Homemade compressor At home, you can also build a bottom aerator. This is easy to do if you have a car compressor with a receiver. So, we need:
You can make the latter yourself. For this, for example, you can take several plastic bottles with a capacity of 0.5 liters. Holes are made in them with the help of awl. In order to leave the bubbles were even smaller, you can wrap the vessels in foam rubber.
How to make the compressor yourself using the compressor from the refrigerator, see below:
Before the first start, it is better to set the pressure to a value less than the average. You can add it as needed. One of the weeks The statuses of such a system will be the impossibility of its continuous use, as well as noise.
If you do not have a compressor, you can replace it with a motor from a conventional vacuum cleaner. In this case, it’s better to use not high pressure hoses, but ordinary ones corrugated. It is also necessary to correctly calculate their length so that the flow can calmly push them through.
The wind aerator is good for winter
The next type of adaptation will be especially relevant in winter, when engines do not feel so well. It also does not require the supply of electricity and operates completely autonomously. For manufacturing, we will need:
The wind turbine
The assembly process will be as follows:
The wind spins the blades, through the shaft the force is transmitted to the propeller from the bottom, which creates turbulence, saturating the water with oxygen and preventing it from freezing in winter.
Blades can be made from any sheet metal or other material. Most importantly, arrange them so that they can catch air flow. The platform itself can be made floating. To do this, use foam, plastic barrels, old bottles or bottles. So that the construction does not swim far away, it is tied with a cable to the shore.
Based on these solutions, you can build a structure that will fit your needs. We are interested to know what happened to you personally. Share your ideas in the comments.
