Configurations
Floating Treatment Wetlands Configuration
Designed to fit your site and scale with your needs
A defining feature of Atlan’s approach is modularity. The flexibility allows projects to evolve alongside site conditions, budgets, or treatment requirements.
- Systems are made up of scalable floating units
- Installations can be integrated into existing water bodies without major structural changes
- Systems can be sized precisely to match treatment requirements
- Modules can be expanded or adjusted over time
- Installation is faster and less disruptive than fixed infrastructure
Floating Treatment Wetlands Configuration
Our modular system supports flexible configurations and sizes
Sizing & coverage
Rather than a one-size-fits-all solution, FTWs are configured to provide targeted surface coverage that supports effective treatment without compromising the function of the water body.
The size of a Floating Treatment Wetland is typically determined by:
- Water body surface area
- Pollutant load (nutrients, sediment, runoff inputs)
- Desired treatment outcomes
- Hydraulic conditions (flow, retention time, depth)
Plant selection
Planting plays a critical role in performance and appearance. Well-selected vegetation enhances pollutant removal while contributing to biodiversity and visual appeal.
Selection considers:
- Native and site-appropriate species
- Root structure and growth behaviour
- Nutrient uptake capability
- Seasonal performance and resilience
Integration Into treatment trains
Floating Treatment Wetlands are rarely used in isolation. They are configured to work alongside other systems to maximise performance. Positioning within the treatment train is a key design decision that directly impacts effectiveness.
Typical integrations:
- Upstream gross pollutant traps (GPTs) to remove litter and debris
- Sedimentation zones to reduce heavy solids
- Downstream filtration or polishing systems
Site-specific layouts
Layouts are developed to balance treatment performance with accessibility, safety, and aesthetics.
FTWs can be configured in a variety of layouts depending on site goals:
- Perimeter installations along shorelines
- Central clusters within lakes or basins
- Flow-path positioning to intercept incoming runoff
- Feature-based designs that enhance visual outcomes
