Why a wetland is an efficient solution to treat wastewater?
Management of waste we produce, both in domestic and industrial use, is one of the main challenges we face in modern societies.
The way in which waste is managed has an important impact on both public health and the environment, as well as a high economic cost for the institutions in charge.
Currently most generated waste is buried underground, that is, placed in controlled waste tanks, as it is the most economical way to dispose it. However, this represents a high risk to the environment and health, in addition to a large waste of materials.
So Ecorkwaste project poses a different and useful output for waste water. Waste water will be decontaminated by a treatment system that uses byproduct of cork industry.
Ecorkwaste wants to demonstrate the technical, environmental and economic aspects of the valorization of the byproduct of cork industry.
The way to do this is by constructing a wetland for the treatment of waste water from a cellar using byproduct of the cork industry as the granular media. And also, the byproduct used in the wetland and other byproduct of the cork industry will be gasified in a pilot plant in fluidised bed to obtain energy.
The following image shows graphically the operation of the wetland:
Several studies confirm that cork is a good material for fixing the biofilm in wetlands and that the use of wetlands could reduce the cost by up to 40%.
The main benefits of wetlands in the management of wastewater from the industry are:
Simple operation and maintenance.
Capacity of pollutants removal.
Through Ecorkwaste project we are building and implementing wetland to treat wastewater from the production of wine at Codorniu (Barcelona), where cork is the main means of union.
In the coming weeks the wetland will be completed and it will begin the tests to run it at full capacity.
