Specialist diffused aerators and aeration systems designed, supplied and installed by Heathland Group 

Diffused aerators are a great choice for most lakes or reservoirs. During the summer months most ponds, lakes and reservoirs can suffer from water quality issues and sometimes aeration is often necessary.

Thermal stratification in lakes, ponds and reservoirs

Lake, reservoirs and ponds often suffer from a process called thermal stratification. Thermal stratification is the development of layers within the water. On the bottom of the water body, a cooler, oxygen-depleted layer will develop which is separated from the warmer, oxygen-rich layer on the surface by a middle layer called the thermocline. The difference in water density at the thermocline prevent the lower layer and surface layer from mixing, which causes harmful gasses to be trapped and oxygen levels to decrease. Diffused aerators help to combat this issue.

By aerating a water body from the lake bed, the trapped toxic gases are pushed through the thermocline and are able to escape. This helps to balance the ecosystem in the lake or reservoir. The diffused aeration process also creates aerobic conditions and microbial processes can naturally break down nutrients. These nutrients might otherwise be used in the formulation of noxious aquatic weeds and algae.

Expertly designed diffused aerators and aeration systems for lakes and reservoirs

The diffused water aerators and aeration systems designed and installed by Heathland Group pump air through the diffuser membranes, which then travels to the surface in the form of millions of tiny bubbles. As these bubbles ascend through the layers of thermal stratification they entrain water. This water is naturally oxygenated once it reaches the surface of the water.

A range of diffused water aerators are available

We have a range of systems available, because of this, we can usually find a suitable aerator for your aeration requirements.  Our diffused water aerators and aeration systems are designed for each individual application. This ensures thorough aeration and helps improve the natural ecology of the waterbody.

Features and benefits of diffused water aeration

  • Diffused water aeration increases the breakdown of aquatic waste. It provides a habitat beneficial for aerobic bacteria to flourish.
  • They break up thermal stratification throughout the water column. This allows the water column to be oxygenated thus eliminating highs and lows in both temperature and oxygen levels.
  • When operating continuously in freezing climates these aerators keep areas in the ice open and moving. This allows toxic gases to escape and maintain the oxygen levels in the water.
  • Winter operation will keep areas free of ice to allow birds and other wildlife to access the much-needed water they require during freezing conditions.
  • Aerators prevent fish kills normally seen in freezing conditions due to depleted oxygen levels or gas eruptions. These are linked to rotting vegetation.
