An ecological bird farm in Wales widely appreciated for their circular farm economy uses the chicken litter turned into digested sludge as a feedstock for their biogas plant. A very fibrous sludge is then thickened to the concentration of approximately 7 % of suspended solids. The customer needed to dewater 10 m3 of thickened digested sludge per day to streamline their procedure.
The VOLUTE DUO™ dewatering press proved suitable for this highly fibrous sludge demonstrating a very stable and effective solids liquid separation. An average of 25 % of DSC in the dewatered cake, and the low-maintenance operation made the contactless twin screws screw press a great fit for this application.
