Pond Aerators

In stagnant water bodies, it is important to maintain an optimal amount of oxygen in the water. Its deficiency leads to a deterioration in the condition of water, making it unsuitable for inhabitants and some plants. Aerators are used to prevent the formation of mold and water stagnation. These are specialized devices for supplying oxygen to water. They are presented in a wide variety of models, differing in appearance, functionality and other parameters.

Aeration is the process of saturation (enrichment) of water with oxygen, as a result of which its condition improves. By reducing the volume of carbon dioxide, the liquid remains transparent, and fish and plants receive the required amount of oxygen. The device also provides additional circulation, eliminating thermal stratification. Use the pond aerator in the following cases.

• Activation of the growth processes of beneficial representatives of the flora.
• Creation of comfortable conditions for underwater inhabitants.
• Prevention or retardation of algae bloom and reproduction.

Aerators are in high demand. Equipment can be categorized based on placement, design features and other parameters.

The variety of models is great.

• Membrane aerators. The volume of the pond is 15 cubic meters. The noise level is low noise. Scope of use - decorative reservoirs.

• Reciprocating. The size of the pond is from 10 to 300 cubic meters. The noise level is average. Scope of use - decorative reservoirs.

• Vortex. The minimum size is from 150 cubic meters. Noise level - noisy aerators. The area of ​​application is fish-breeding ponds.

Also, modern manufacturers use the following division.

• Fountains. To assemble such a system, you will definitely need hoses (for oxygen) and a pump that will keep the structure afloat. Optionally, you can install a sprayer. The floating fountain effect is important not only from a practical but also an aesthetic point of view.

• Visor. Such structures operate on wind power, without electricity. The wind aerator is operated by blades that drive the technical equipment. The wind aerator can be positioned as desired, as it does not require a compressor. The blades can be made of stainless steel or plastic.

• Water pump. An easy-to-use option that does not require complex maintenance and installation. It is great for small artificial ponds.

By type, the systems are divided into such options.

• Stationary models. This is a large-sized equipment. When choosing it, they are guided by a specific pond (its size, depth and other characteristics). The aerator operates in a special mode or around the clock.

• Mobile. Compact devices designed for a specific season or temporary use. The equipment can be moved from place to place.

According to this parameter and working principle, pond aerators are divided into specific categories.

• Superficial. This is a technique in the form of "living" waterfalls or fountains.The visual effect emphasizes the decorativeness of the reservoir. The noise generated during the operation of the compressors may disturb some fish and other inhabitants. This characteristic must be taken into account. The principle of operation of such equipment is quite simple. Water is sucked into the aerator using a pump and then thrown back with acceleration. Particles of air enter the liquid, which saturate the pond with oxygen.

• Combined. These models have two parts. The compressor is installed on the shore, and the spray is placed in the pond. Above the surface of the water is the spray head through which the liquid flows. He saturates the water with oxygen.

• Wind. Such devices perform all functions autonomously, on the strength of the wind, saving money on electricity. Manufacturers offer floating and stationary models. Above in the article, we have already considered aerators of this type, their design features and other characteristics.

• Bottom. This type has appeared on the market relatively recently and has become widespread due to its high efficiency. The compressor is installed on the shore, and diffusers with tubes are immersed in the reservoir. The liquid passes through narrow pipes and at the outlet it penetrates through the layers of water. This option is the best choice for locations with fish, turtles and other similar fauna. Among the many advantages, bottom aerators have one significant drawback - the high price.

Among the wide variety of aerators, users have chosen certain models and compiled a list of units that are great for a summer cottage and larger bodies of water.

Floating craft with high power ratings. It is suitable for ponds up to 250 square meters. Oxygen particles will penetrate to a depth of 4 meters. The device will keep a stagnant pond tidy, but it is also great for running water ponds. The aerator will maintain biological balance by preventing blooming.

Features of the model:

• specialists used an injection nozzle, with which it is possible to control the accuracy of the oxygen supply;
• high-speed functioning;
• noise level - low;
• for the manufacture of individual parts used stainless steel;
• type of drift - sealed;
• long service life.

Specifications:

• dimensions (length / width / height) - 725x555x310 mm;
• the minimum depth for work is 0.5 meters;
• efficiency - 650 W;
• in one hour, the device pumps 3000 liters of air per hour;
• the maximum size of the pond is 250 thousand liters;
• wire length - 30 meters;
• the actual cost is about 180 thousand rubles.

A bottom type aerator designed for large ponds up to 4 thousand square meters. The set includes a bottom water spray, a compressor and a metal stand.

Equipment features:

• the device can be used at a depth of 15 meters;
• during operation, the technique consumes a minimum of electricity;
• the aerator constantly mixes the water, enriching it with oxygen;
• the model is suitable for use all year round.

When choosing a device, it is imperative to pay attention to certain parameters.

• The size and volume of the pond. This characteristic is directly related to performance. The larger and deeper the reservoir, the more powerful an aerator will be needed. It is recommended to purchase a model with additional power reserve so that the wear process of the equipment proceeds slowly.
• Noise level. If there are underwater inhabitants in the pond, the sound of the pump may be uncomfortable for them. Also, the high noise level is not suitable for bodies of water that are located near houses.
• Seasonal operation. Some models are designed for use in the warm season, others are designed for autumn and winter. Also on sale you can find universal equipment that can work all year round.
• Working modes. The more efficient and functional the equipment is, the more expensive it is. However, for some cases, only an aerator with a large number of operating modes is suitable.

Additional parameters to look out for:

• trademark;
• guarantee period;
• materials used in the manufacture of equipment;
• appearance.
