> 75 stations for semi liquid manure treatment removing nitrogen and phosphorus (94% of nitrogen and up to 85% phosphorus).
Created in the 1990s to adjust to the problems of lack of spreadable surfaces, Dénitral sells, builds and operates pig waste treatment plants.
The team Dénitral, a subsidiary of Cooperl elaborated the biological treatment of manure using specific technologies called Filtramat (separation by filtration) and Skimmat (biomass dehydration)
The stations managed by Dénitral are designed to bring a soluton adapted to every breeding to manage at best their surpluses of nitrogen and phosphorus. Dénitral also collects the solid materials in the breedings to transfer them to Cedev to be dried.
