Water aeration is the process of adding oxygen to water by increasing its exposure to air. It involves various techniques and equipment to introduce air or create turbulence in the water, allowing for the exchange of gases and promoting the dissolution of oxygen. Water aeration helps improve water quality, supports the health of aquatic organisms, and mitigates issues like stagnant water, foul odors, and excessive algae growth.
Keep your waterbody in perfect condition by investing in a long-lasting, reliable aerator.
Diffuser based aeration systems are a proven and effective approach for mixing waterbodies and raising dissolved oxygen levels, which is vital for a healthy waterway.
Each diffuser acts as an airlift pump entraining water from throughout the water column within the rising bubble plume, which then spreads across the surface where it is oxygenated by the atmosphere before heading back towards the bed and diffuser.
Aeration systems are used to:
- combat problems associated with stagnation and odour generation
- control duckweed in canals
- reduce ice formation in the winter
- reduce nutrient and pollutant mobilisation from sediment
- consolidate sediments through the breakdown of organic components
- increase the diversity of benthic aquatic invertebrate fauna
- prevent fish kills
If your waterbody suffers from toxic blue green algae blooms, it’s a mixing system you need.
Diffused Aeration for Water Quality
Some waterways are less affected by wind movement than others which can result in ecological imbalances. These waterbodies can become stagnant, resulting in excessive weed growth and odors. Diffuser based aeration ensures that water quality is maintained.
Specifically during the summer months, waterways can also suffer from thermal stratification. This is the process of a waterbody developing layers which differ in temperature and oxygen levels. At the surface of the water, there is warmer, oxygen rich water and at the bottom there is a layer of cooler water with low oxygen levels. These layers are separated by what is known as the Thermocline Layer, which differs in density to the other layers. As a result of this, the top and bottom layers are prevented from mixing efficiently.
Stratification can have detrimental effects on the quality of a waterway, including unpleasant smells, excessive plant growth and fish kills which are all associated with stagnant water. Incorporating appropriate diffuser based aeration into your waterbody helps to maintain healthy ecological conditions and create a balanced habitat, therefore avoiding these issues.
Why choose ISS Flowthrough?
Traditional diffuser – based aeration systems are designed around individual airlines feeding each diffuser, which requires deployment of multiple airlines. In these systems, the airflow to each diffuser unit is manually balanced via a bankside manifold. As such, traditional systems are difficult to implement successfully on linear waterbodies and require long lengths of multiple airlines to be deployed. Additionally, the airflow has to be balanced across multiple diffusers over extended distances which is extremely problematic.
ISS-Flowthrough are able to offer a unique aeration system through use of a patented air flow regulation process that allows a large number of diffusers to be operated from a single narrow bore airline.
As a result of this regulation, the correct optimal volume of air is delivered to each diffuser within the waterbody regardless of its position or depth.
Our diffuser based aeration systems are effectively self balancing which makes them simple to operate and maintain.
We are able to design bespoke aeration systems for a wide variety of locations:
