Your Guide to Choosing the Right Dam Aerator

As a dam owner, you’ve likely come across dam aeration systems before. You might not have thought you needed one, or you might not have had the time to find the right one yet, but we’re here to help.

Your dam water is likely home to a whole host of aquatic life, including beneficial bacteria, plant life, fish, and other organisms. A dam aerator can help to improve the water quality of your dam to ensure this life lives on and that you, yourself, can get the most out of your dam.

But how do you choose the right aeration system for your dam?

This guide will give you an overview of the role of dam aeration systems, how they benefit your dam, and how you can go about choosing the right dam aeration system for your water body. Take a look below now.

The Role of Dam Aerators

So, what do dam aerators actually do?

A dam aeration system is used for three main goals: to oxygenate the water, to enhance the water quality, and to support the aquatic ecosystem in your dam. Implementing a dam aerator will enhance the levels of dissolved gases (mainly oxygen), which is absolutely vital for living organisms in the water. If the living organisms can survive better, then the overall ecosystem will be more balanced and healthier.

Benefits of a Dam Aeration System

Dam aeration has a tonne of benefits for your dam, including:

  • Increasing oxygen levels
  • Preventing stratification or ensuring the mixing of layers of water to ensure oxygen is distributed evenly throughout the dam
  • Preventing anoxic conditions, or exceptionally low oxygen levels which can kill aquatic life
  • Inhibiting algal blooms, which cause a whole host of their own problems for dams
  • Preserving the biodiversity of your dam, including a balance between aerobic bacteria and anaerobic bacteria
  • Controlling nutrient cycling to prevent problems like eutrophication
  • Reducing stagnation and the likelihood of floating debris
  • Prevent ice formation on the surface of the water during winter

How a Dam Aerator Will Improve the Water Quality in Your Dam

Dam aeration is a holistic approach to improved water quality and a balanced ecosystem. But how exactly does an aeration system work?

When placed in water in a dam, aeration systems work by a process of diffusion. The devices release fine bubbles of air into the water to improve oxygen levels. Aerators are often placed at strategic depths and points throughout the dam to ensure the effective distribution of oxygen throughout.

The configuration of aerators may depend on the depth and size of the dam but can include both surface aerators and bottom aerators to ensure oxygen is distributed evenly throughout.

In addition to the introduction of fine bubbles into the water, the air release from the diffusers caused what is known as a bubble plume. This plume reaches the surface of the water and induces mixing throughout the water column, preventing stratification in your dam.

How to Choose the Right Dam Aerator for Your Dam

Choosing the right aeration products for your dam will include a few considerations. In our time, we’ve helped many of our customers find aeration systems to suit their unique dam, and we can help you, too. Below are some of the considerations you will need to make before choosing a system for your dam.

Considering Dam Size and Depth

Dam size can have an impact on the kind of aeration you choose. While a smaller dam may need one simple system, larger and deeper dams may need a little more strategy.

To ensure that your aeration reaches all points of your dam, you will need to consider how many systems you need and whether you will need to place them at different depths throughout the water.

You can buy systems, like the Matala Air Station, with multiple diffusers to ensure your aeration efforts reach a wider area.

Your Aeration Goals

Aeration, in general, improves your water quality, but you may have a specific goal for your system. For instance, you may want to prevent stratification in your dam, which can be done by choosing a system that prioritizes mixing layers of water.

You might choose a system like the Matala Fine Bubble Air Diffuser Disc 250, which sits on the bottom of your dam and ensures water mixes throughout the levels of your dam.

Different Aeration Systems

There are different styles of aeration products which you will need to consider. Many aerators sit on the surface of your dam, whether by themselves, like the self-weighted Matala Fine Bubble Air Diffuser Disc 350, or by filling them with gravel, like the Matala Air Station Diffuser. These are known as sub-surface aerators.

Surface aerators, on the other hand, look more like a water feature and use the ripple effect on the surface of the water to allow harmful gases, like methane, to escape and oxygen and other good gases to enter the water.

Surface aerators may sometimes be called aerating water fountains, too. Water features themselves can offer a small amount of aeration ability, even if they’re not aerating themselves, simply by moving the water and helping to avoid stagnation.

For deeper dams, surface aeration is not enough, but if you have a shallower dam, you may want to consider a non-aerating feature like the Matala Floating Fountain.

Energy Efficient Aerators: Solar Aerators and More

Lastly, you might want to consider the energy efficiency of your system. Aeration can be costly, especially when you consider that it is constantly on to ensure good water quality.

If you’re looking for an energy-efficient aerator, you may consider solar aerators, which are powered by solar panels on the aerator’s surface. Solar aeration is an excellent option for those looking for an environmentally friendly method of aeration.

You can also find hybrid solar aerators if you live somewhere where constant sunlight, and therefore solar aeration, might be an issue. And if you’re considering a water feature, you can also find solar aerating fountains, too.
