Sludge drying technology
WebbPrinciple of superheated steam drying. The material to be dried is introduced to the superheated steam atmosphere where it is heated up convectively after which its moisture evaporates. This heat transfer process is enhanced effectively, since superheated steam has a high heat capacity and thermal conductivity. WebbThe sludge drying device is simple in structure and scientific in design, manual feeding is not needed, discharging after sludge drying is convenient and rapid, manpower and material...

WebbThe dewatered sludge can be fed into the greenhouse either manually, i.e. with a wheel loader, or fully automatically by a distribution screw that utilizes the evaporation area optimally. The dried sludge is discharged … WebbSludge-drying beds provide the simplest method of dewatering. A digested sludge slurry is spread on an open bed of sand and allowed to remain until dry. Drying takes place by a combination of evaporation and gravity drainage through the sand. A piping network built under the sand collects the water, which is pumped back to the head of the plant.
