Diffused Reservoir Aeration Systems | Heathland Group Ltd

Why choose diffused reservoir aeration systems?

Reservoirs often suffer from oxygen depletion and thermal stratification, leading to poor water quality, algae blooms, and fish kills. Our diffused aeration systems work by evenly distributing fine bubbles of air at the reservoir bottom, promoting oxygen transfer and circulation to maintain optimal dissolved oxygen levels throughout the water column.

Why do you need to aerate your reservoir?

Reservoirs can be affected negatively by warmer weather. During the summer, reservoirs can suffer from thermal stratification, which is when water becomes divided into layers as shown below. The bottom layer of the reservoir will contain cool, oxygen-depleted water whilst the surface layer of the reservoir will contain warmer oxygen-rich water. These two layers are separated by the thermocline that prevents the two from mixing because of differences in the water density.

A diffused aerator pumps air through the diffuser membranes, which then travels to the reservoir 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 reservoir base upwards also releases toxic gases that normally become trapped underneath the thermocline layer. This provides a balanced habitat for aquatic life. This diffused aeration process creates aerobic conditions near the reservoir 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.

How can your reservoir benefit from diffused aeration

• Aeration breaks up thermal layers in the water column allowing the entire column to be oxygenated, eliminating highs and lows in temperature and levels of oxygen.
• Increased oxygen levels will be passed through the irrigation process and provide crops and plants with stronger healthier root systems.
• Diffused aeration increases the breakdown of aquatic waste by creating a habitat beneficial for aerobic bacteria to flourish.
• When an aerator is kept on in freezing climates, the pumps will keep areas in the ice open and allow toxic gases to escape, increasing the oxygen level in the water.
• Aerators operating throughout winter keep frozen areas of the reservoirs open so birds and other wildlife still have access too much needed water in freezing conditions.
