Wastewater Treatment with a Nature-based solution

Development Area: Water / Operational Equipment

 

NatureWaves® – based solution to treat wastewater in Loulé – Portugal.

The Nature-based Solutions use nature and known natural processes to help provide viable solutions to protect the environment such as in the wastewater treatment or ecosystem recovery. The NatureWaves® fits perfectly as a solution that uses the knowledge of nature and its processes, for a perfectly natural way to treat wastewater and restore the ecosystems.

 

The growing popularity of NatureWaves® is due to it being a solution with a double benefit. On the one hand it has the ability to provide a natural solution for the decontamination of water, and on the other hand to capture greenhouse gases such as methane (CH4) and carbon dioxide (CO2).

Plant roots play a key role in wastewater treatment processes. The contact that is provided by the roots with the water leads to the development of biofilms containing communities of microorganisms responsible for several very important treatment processes. This symbiosis allows the removal of BOD5, Total Suspended Solids, Nutrients, Pathogens and others.

Testimony

“During the year 2013, with a disruption in the treatment process of our WWTP, which was manifested by an increase in the concentration of the parameters of total nitrogen and nitrates in the final effluent, above the emission limit values, it triggered a corrective action, within the scope of our Environmental Management System.

Thus, in 2014 the NatureWaves® was installed with macrophytes in the maturation pond of the WWTP. In addition to the plants absorption of greenhouse gases such as methane (CH4) and carbon dioxide (CO2) and simultaneously release oxygen (O2), this action allowed an effective treatment of the wastewater, to values below 5 mg/L in both parameters and the elimination of unpleasant odours associated with wastewater treatment.

The NatureWaves® continues to work today and has the advantage of providing a decontamination solution with a passive, natural, low maintenance and very simple operation process.”

The NatureWaves® can be applied in the retrofit of conventional Constructed Wetlands, avoiding the costs associated with the removal, transport and deposition of the contaminated substrate. In a retrofit the NatureWaves® also manages to improve the treatment parameters, increasing the life time of Constructed Wetland and definitively eliminate the clogging problem.
