Waves Floating System

The constructed wetlands have been used as natural environments for the treatment of wastewaters.

Its growing popularity is due in part to the fact that the treatment system offers the advantages of a solution for the water decontamination with a passive process, natural, low-maintenance and very simple operation.

The Waves Floating System (floating islands) emerged as a natural evolution of the constructed wetlands, and have been studied in a variety of applications, such as improving water quality, habitat creation and treatment of different types of wastewater.

Compared with the conventional constructed wetlands, which have a predominantly depth of 0,5m of soil, the Waves Floating System don't need any soil, allowing to be constructed with a greater depth to provide an additional volume of water to reduce the flow speed and increase the yield.

The Waves Floating System enables to eliminate unpleasant odours associated with wastewater treatment. In addition, plants absorb greenhouse gases such as methane (CH4) and carbon dioxide (CO2) and simultaneously release oxygen (O2).

The plant roots play a key role in the wastewater treatment processes, due to the contact provided with the water. The plants roots provide an area for development of biofilms communities containing microorganisms responsible for a number of very important treatment processes. This symbiosis allows removal of BOD5, nitrogen, phosphates and others, and their incorporation into plant biomass.

The thickness of the root network and associated biofilm, are effective in physical capture of particles within the water column, which subsequently detach the roots in the form of heavy particles, which are more susceptible to settling. On the other hand no use of soil prevents the clogging of the medium and the creation of sludge.

Noteworthy are the following advantages of the Waves Floating System in wastewater treatment:
- Retrofit and adaptability to solutions already built;
- Without the beds clogging and without the costs of transport and deposition of the beds;
- No emission of unpleasant odours;
- Energy costs inexistent;
- Low cost of installation;
- Reduced maintenance;
- Low operation cost;
- Compliance with applicable laws;
- Possibility of water reuse;
- High life time with no intervention;
- Constant operation 24 hours a day, 365 days a year;
- Ability to withstand variations of flow.

The Waves Floating System can be used:
- in the retrofit of WWTP;
- in the treatment of wastewater from:
a) Industries;
b) Small communities;
c) Rural areas;
d) Agricultural and Livestock farms;
e) Military camps;
f) Golf courses;
g) Hotels and Resorts.
- in ecological restoration.
