Heathland Group provide a variety of reservoir aeration options to keep your reservoir aerated and in overall good health. Our range of reservoir aerators are available in floating or diffused options;
Floating Aerators – surface aeration
Diffused Aerators – circulating water from the reservoir bed which aerates at the same time.

Heathland Group will provide the perfect standard or bespoke aeration system for your reservoir aeration needs. We have over 30 years of experience working with aeration. All the calculations relating to your aeration requirement are made in-house to provide you with the right piece of equipment for your reservoir’s water management requirements.

Diffused reservoir aerators and their benefits
Reservoir water aeration can help increase productivity in many ways, a few examples of this would be the increase of oxygen-rich water into the root systems of plants and crops not to mention the huge reduction in single-cell algal blooms which can cause timely maintenance issues with filter blockages. Heathland Group has several effective solutions in our range of diffused reservoir aerators and can provide a choice of disc and tube styled diffuser membranes. Tube style diffuser membranes entrain water from 360 degrees around the tube and this allows them to reach deeper water from the bottom of the reservoirs, whilst the base design prevents them from actually disturbing the reservoir bed. Disc style diffuser membranes entrain water from the top of the membrane up towards the reservoir surface.

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 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.

Key features and benefits of diffused aeration systems in your reservoir;
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 to much-needed water in freezing conditions.
