Patent DE-19825985-A1 (DE)
Title: Rotating sieve for removal of particulate matter from continual flow of water
Inventor: BEVER JUERGEN DR ING
IPC: B04B3/00
Filed: 1998-06-10
Abstract: The removal of solid particles from a liquid is by a sieve centrifuge. The fluid to be filtered is discharged into the rotating sieve. Liquid passes through the sieve, while concentrated solid particles are retained and discharged from time to time. The rotating sieve also generates primary and secondary turbulence which prevents blockage of the sieve by the concentrate. The direction of liquid flow into the sieve promotes a self-cleaning action.
