Lagooning of VAUVERT suffers no more duckweeds.

 VAUVERTAVANTAPRES  

The municipality of VAUVERT acquired 2 solar-powered SUBMIX mixers to treat the duckweeds which appeared on the whole surface of the vegetated discharge area : It is a downstream processing of sewage treatment plant, which puts in motion water in a vegetated area in order to degrade some of the micro-pollutants.
Azola lenses were worrisome, as they stop photosynthesis by blocking sunlight. With the two mixers, lenses have been disturbed and soon, they disappeared. 
This is an example of the hydrobiological knowledge of the AQUAGO team, which has a strong experience in the struggle against invasive aquatic plants.
