Treatment of Water using Aeration

Aeration Bubble Curtains

Using Bubble Curtains for planned and reactive aeration and emergency oxygenation sustains dissolved oxygen and protects aquatic life.

Bubbles breaking surface tension to form a barrier

Bubble Curtains can be rapidly deployed to boost, maintain or restore dissolved oxygen in rivers, lakes and reservoirs.

Using Bubble Tubing® diffusers laid at or near the bed, each system releases a plume of fine bubbles that drives vertical mixing and delivers unparalleled oxygen transfer efficiency.

This benthic aeration helps sustain DO thresholds, mitigates low-oxygen incidents during works or pollution events, and protects aquatic ecosystems.

In reservoir applications it can also support manganese oxidation, improving raw water quality.

  • Designed for emergency response or planned programmes, Bubble Curtains are quick and simple to deploy, connecting to standard site tool compressors for immediate use or to silent and renewable-powered compressors for longer-term, low-noise operation.
  • Systems are configured to site conditions (length, depth, flow and access) and can be arranged as straight runs, arcs or enclosures to match the objective.
  • For sustained, heavy-duty aeration and destratification, pair or upgrade to one of our OctoAir® aerators.

Key Benefits

Breathing life back into water

Rapid oxygenation

Helps restore dissolved oxygen above critical thresholds, reducing the risk of fish kills and ecological damage

Benthic aeration

Delivers oxygen close to the bed, improving water quality and resilience in deeper or stratified systems

Does not obstruct navigation

Bubble Curtains form a permeable barrier, allowing vessel and wildlife movement while oxygenating water

Flexible deployment

Suitable for planned works or emergency response, with layouts that can be moved as conditions change

Manganese oxidation

Supports treatment of manganese in reservoirs, reducing treatment costs

Cost and carbon efficiencies

Re-usable across projects, low maintenance, and switched off when not needed to reduce operating costs

Every Bubble Curtain is designed around site conditions. Key design considerations include:

Scope of project Curtain length, water depth, flows, tidal range, bathymetry, and access
Layout Geometry (linear, arc, enclosure)
Weighted options Anchoring and moorings to suit substrate and flow conditions
Compressor We will provide specification including oil-free, energy-optimised units with low noise options
Maintenance Self-purging perforations minimise fouling
Validation Tested for aeration, oxygen transfer calculations are performed by our Technical Team to support design optimisation for responsive and planned projects
Warranty Supplied with a 5-year manufacturing warranty

“Thanks to Frog’s technical expertise and insight, we have found new ways to tackle these common issues and improve our site water management practices – from company-wide awareness and training to monitoring and prevention. As a consequence, we have made significant cost savings and lowered our carbon emissions.”

“The results (of the bubble curtain) were quite dramatic – in fact, startling… we have a workable solution that we’ve proved has a dramatic impact on noise propagation.”

It’s good to see Frog getting involved with GT at the earliest stages of the project to help with planning out water management in advance of needing it.

“Frog Environmental were knowledgeable, helping to establish a workable, cost-effective and low maintenance solution for site approved by the regulator. They really understood the water management issues we had on site and worked with us to develop a solution which works, as well as engaging with our operatives to ensure that they could effectively manage the system.

We are delighted to have found a solution that prevents pollution and protects the environment, and ultimately allows us to continue with construction.”

The surface water system drainage feature utilised innovative solutions from Frog Environmental.

A rain-ready strategy was implemented, which enabled the development of a robust management system capable of effectively managing fluctuations in weather conditions year-round.

This provided a timely, sustainable and cost saving solution for our client.

Frog’s commitment to develop innovative, market-leading strategies to help their construction clients take responsibility for their sites has and is inspiring an industry-wide change in management culture to improve environmental practices. Of note is their “Rain Ready” water treatment system which is setting new benchmarks in environmental excellence.

“The systems were very effective, and we can see how they could be used on other projects. Being able to talk through the scenario with Frog Environmental was really helpful… We were so pleased to be able to proceed with this essential works with no disruption to either wildlife or our workplan, it saved us time, money, and provided peace of mind that we had taken effective steps to protect the environment.”

They (Frog Environmental) were efficient in providing advice and the most appropriate product for our project. The team responded promptly to ensure the Bubble Curtain was delivered to the site on schedule.

It has worked well and has been great on site. We are demobilising this week, and the bubble curtain is already in store at our next site for reuse!

The Kex Gill road realignment scheme is a challenging project with multiple environmental risks including management of silt and water quality of the surrounding environment given the locality of designated sites.

Frog Environmental are providing us with extensive technical support, including the design, supply and install of their silt control products on site to ensure the project minimises risks to the watercourses in the project vicinity and prevents impact on highly sensitive aquatic species.

It’s great to be working with them and we’re delighted with the success of the whole project.
