How to Aerate a Lake

Here at Heathland Group, we offer two types of lake aeration, diffused aeration, and floating aeration to help you efficiently aerate your lake.

Diffused Lake Aeration

So, what is diffused lake aeration?

A diffused aerator pumps air through the diffuser membranes, which then travels to the surface in the form of millions of tiny bubbles. When these bubbles travel up through the thermal layers they entrain the colder water and this is then carried to the surface layer, where it becomes naturally oxygenated. This colder water circulates and is replaced by warmer water providing complete circulation and balanced temperature.

Circulating and aerating from the base upwards also releases toxic gases that normally become trapped underneath the thermocline layer. This provides a balanced habitat for aquatic life. This aeration process creates aerobic conditions near the water bed and then the microbial process can naturally break down nutrients that might otherwise be used in the production of noxious aquatic weeds and algae.

Supplying & installing diffused lake aerators

Heathland Group can provide a variety of diffused air aerators for lakes. We offer diffused lake aeration from both tube or disc-style diffuser membranes, so we have aerators to suit everyone. Disc-style diffuser membranes entrain water from the top of the membrane up through the water column. Tube-style diffuser membranes entrain water from 360° around the tube. This allows them to reach deeper water which helps aerate the lake bed and promote sediment and silt digestion.

What are the benefits of diffused lake aeration systems?

During the summer most lakes tend to suffer from thermal stratification, a process by which the lake water develops layers. On the bottom of the lake, you’ll have cooler, oxygen-depleted water. This is separated from the warmer oxygen-rich water on the surface of the lake by a layer called the thermocline. The differences in water density at the thermocline mean that the top layer and the bottom layer are prevented from mixing. This causes harmful gasses to become trapped and oxygen levels to deplete.

Incorporating diffused lake aeration

When you incorporate diffused lake aeration from the lake bed, the trapped toxic gasses that became trapped are pushed through the thermocline. They are then able to escape, helping to provide a balanced habitat in your lake. The aeration also creates aerobic conditions near the lake bed, where microbial processes can naturally break down nutrients that might otherwise be used in the production of noxious aquatic weeds and algae. During this process, the diffused aeration also circulates the entire water body. It does this by pushing the lower water column to the surface, as this process takes place surface water is drawn down.

Heathland Group’s diffused air aeration systems pump air through the diffuser membranes. This air is then able to make its way to the lake’s surface in the form of millions of tiny bubbles. As these bubbles travel upward through the layers of thermal stratification they entrain water with them. This water is carried to the surface where it becomes naturally oxygenated, thus aerating your lake.

Key features and benefits of diffused lake aeration in your lake;

  • Breaks up thermal stratification throughout the water column. This allows the entire water column to be oxygenated and eliminates highs and lows in both temperature and oxygen levels.
  • Increases the breakdown of aquatic waste by providing a habitat beneficial for aerobic bacteria to flourish.
  • When operated continuously in freezing climates, these aerators will keep areas in the ice open and moving. This allows toxic gases to escape and maintains the oxygen level in the water.
  • Winter operation will keep areas of frozen lakes open. This allows birds and other wildlife to gain the much-needed water they need during freezing conditions.
  • Prevents fish kills. This is normally seen in freezing conditions due to depleted oxygen levels or gas eruptions which are linked to rotting vegetation.

Floating Lake Aeration

Specialist floating lake aeration, designed for longevity to support your lake through tough environmental conditions!

The movement of water is an extremely important aspect of keeping your lake healthy and habitable. Floating lake aeration is a great way to achieve good aeration in a lake.  Our surface floating aerators are incredibly important in our catalogue of floating lake aerators. These can provide high-performance lake aeration for your water body.

A floating lake aerator is one of the most common forms of aeration for lakes and reservoirs throughout the world. These aerators are extremely popular and provide the ideal solution for most lake aeration needs without any technical knowledge to install them. Our extensive range of aerators is some of the most effective on the market. This is because they have minimal restriction of water flow from the nozzles, resulting in increased volumes of water flow and the very highest water turnover available on the market. Oxygen is transferred through the process of water collision. During the process air/oxygen is pushed into the water creating what is known as dissolved oxygen or DO. This is essential for the aeration process.

Low-cost, reliable, high-performance floating lake aeration systems

Heathland Group has made it its mission to provide the very best quality aerators on the market. There are certain criteria that we believe all of these products should meet, so we didn’t just aim to meet them, we aimed to surpass them completely. Many of the manufacturers seen on the market will provide some form of surface aeration but none of them can turn over the volumes we can.

Reduced running costs for floating lake aerators

Cost is a fundamental issue for many customers looking to aerate their lakes or reservoirs. Large motors for aerators are no longer a necessity. Instead, how they are set up and the propulsion is the key. Many aerators simply burn power, in other words, they cost more to run and provide very low flow. Performance and efficiency are greatly increased by the state-of-the-art technology that Heathland Group employs. This means reduced power consumption, reducing your running costs.

High-performance floating lake aeration

At 750 watts our flow rates are set at 90,000 litres per hour. This is 50,000 litres more per hour than our competitors’ aerators using the same 750-watt motor rating.

Aerators that offer reliability and longevity

All of our floating lake aerators come complete with 3 years parts (non-wear) warranty and 3 years return to base labour warranty. They all have high-end drives. These use environmentally safe oil-filled motors that extend the life of the aerator well beyond the normal limits. It’s not uncommon for one of these aerators to run for 10 years or more, when professionally installed and well-maintained.

Reduced blockages in your lake aerator

The debris screens on our aerators are larger than average. This creates a larger suction surface area to reduce flow rates through the screen and greatly reduce blockages. Many of the cheaper floating aerators still use traditional pumps to transfer water. As a result, This means easily blocked narrow chambers and fine grills.
