The equipment for dewatering with vacuum, oxygenation and rendering hygienic of slurry involves a biological slurry filter, a dewatering bed, a slurry drainage, a slurry dry bed and a reed bed (13). Incorporated are drainage and air feed conduits (12), coupled to a vacuum tank (11), which is connected to a combined air and vacuum pump (4) via a combined air and vacuum conduit (3). - Excess pressure appertains in the drainage and air conduits with feed of air via the combined air and vacuum pump. Excess pressure also appertains in the drainage and air feed conduits with hot air from the communal or industrial waste water mains (1). After dewatering, organic material is fed to the biological slurry filter bed, dewatering bed, slurry drainage bed, slurry dry bed or reed bed. |
