Wastewater lagoons and reed beds cleanout

Lagoons and reed beds (constructed wetlands) are wastewater treatment plants that accumulate the sludges with a long-term storage, mineralization and volume reduction of biosolids. Periodicaly, the sludges must be extracted from the beds where they are.

Agrosylva is specialised and experimented in sludge removal from lagoons and reed beds that are technical operations requiring care and specific material :

- Lagoons, in case of waterproofing with geomembrane : liquid sludges are pumped either from the lagoon sides either from a flat boat carrying a immersed pump

- Lagoons in other cases : a lagoon is dewatered by pumping, up to the sludge layer. The influent flow is routed to an other lagoon. The sludges dry during several months until they reach a solid consistence. Then, they are extracted with excavators

- Reed beds : The influent flow is routed to another bed. The sludges dry during several weeks, then, are extracted with any excavators
