Floating Wetland Solutions applies materials and engineering expertise with a solutions focus, to supplement the biological processes found in nature in order to improve water quality & ecological health throughout the watershed.
We started as a single product, Floating Islands, company. As we gained experience including lessons learned, we realized that one product wasn’t ideal for every project objective. In fact as project objectives and site conditions varied, we needed different products. Fortunately, with our materials and engineering expertise, we can create Floating Wetland variations that can indeed address a wider variety of project objectives and site conditions.
Evolving from humble beginnings as floating mats with plants, today’s improved designs are constructed from highly engineered materials that are more robust, durable and adaptable. Floating Treatment Wetlands are not just Floating Islands, they are more broadly known as “Floating Wetlands” and they are highly customizable to address varying site conditions and leverage broadly accepted natural science mechanisms that complement and mimic nature for maximize efficacy to achieve the desired outcomes.
One very important advancement is we now have the capability to design and produce our own engineered materials. As a result we can better control quality and our materials are much stronger and durable than other brands. The data below shows how well our material compares with the leading other branda relative to tensile strength and UV degradation.
As project needs present, we can make custom materials that are ideally suited for different applications and environments. We can change material parameters such as: porosity, tensile strength, stiffness, abrasiveness and surface area volume. We can create composite materials with varying material layers and we can add a spray covering to any material for additional qualities such as strength and UV protection.
Our core product, the FWS Floating Island has many improvements and advancements over other brands.
- Perimeter edge area for aquatic plants
- Easier island access for wildlife
- Improved water quality performance along edge due to sunlight and oxygen
- Better aesthetics
- Improved module assembly options
Our standard Floating Islands are made as 5 foot by 8 foot modules for easy assembly.
Our Engineered islands can be highly customized and they include internal conduits with steel rods or cable as needed for the application, to create a Floating Island that is comprised of sections while appearing and functioning like a single unit.
FWS Floating Islands can be deployed in stormwater, waste water, combined sewer overflow, lakes, rivers and estuaries for water quality, habitat, wave breaking and erosion control:
Floating Islands have an anaerobic zone beneath them and they also block sunlight. While these conditions are good for denitrification, they are poor for nitrification. Large Floating Islands can actually reduce dissolved oxygen (DO).
Different than Floating Islands, Floating Wetlands have an aerobic zone in the water above the “mat or plant platform”. The top of the wetland is also exposed to sunlight, thus Floating Wetlands are very good for nitrification, they improve DO and the sunlight exposure promotes healthy perephyton development.
The FWS – Floating Wetland is ideal for:
- Nitrification for Ammonia removal
- De-nitrification for Nitrate removal
- Total Suspended Solids (TSS) reduction
- Phosphorus reduction and sequestration
- Fish & Wildlife habitat, food, shade and protection
- Platform for plants: Aquatic Plants
The BioFil Colloidal Filter is another Floating Wetland variation that was created to reduce coliform indicator bacteria and ammonia. The BioFil Filter targets the colloidal particles that cause water turbidity, provide transport to coliform bacteria, heavy metals, and other pollutants, and degrade habitat for fish and other aquatic life. The open water deployment creates microbial habitat in the most oxygenated portion of the water column, enhancing aerobic processes such as nitrification, the oxidation and removal of ammonia.
Bundling Floating Islands, Floating Wetlands and BioFils creates a solution that combines the best of all features:
Another variation, the BioDi Aerobic Digester reduces organic material, nitrogen, and other pollutants in surface water bodies. The digester’s porous, high surface area substratum provides habitat for microorganisms which break down organic matter and reduce nitrogen via nitrification and denitrification. Spiraling internal flow channels provide highly efficient mass transfer of oxygen and nutrients into the digester to support microbial metabolism, and facilitate removal of sloughed biofilm flocs and metabolites.
The BioDi has direct applications for water bodies with accumulated or high input of organic matter, waste water, or aquaculture systems which have high ammonia levels from fish waste and decomposing organic solids such as uneaten food.
Air diffusers are incorporated at the bottom of the digester core providing oxygen to support microbial metabolism. A key feature of the BioDi is its mass transfer characteristics. While very dense materials may provide large surface area per volume for microorganism habitat, the efficiency of their biological processes is often limited by mass transfer limitations. The BioDi incorporates strategically placed, spiraling, internal flow channels to facilitate mass transfer of oxygen and nutrients into the core, facilitate removal of sloughed biofilm flocs and metabolites from the digester, and influence hydraulic conditions. The digester core is constructed using multiple substratum materials of different density and porosity characteristics, thus enhancing the microbial habitat diversity.
BioDi is especially well suited for larger, deeper and/or rougher water bodies. The digester may be deployed anywhere in the water column as single units or may be deployed in synergistic arrays, such as vertical arrays to maximize oxygen utilization. The submerged digester is advantageous over devices deployed on the water surface in several ways. In climates where the water ices over, the digester can operate year around. In water bodies such as rivers that have flow velocity, large floating pieces of ice may damage a surface dwelling device. In some bodies of water, the digester may be deployed in such a way as to not impede navigation.
