For some sludge handling pro-cesses, it may be necessary to remove, as a minimum, grit of 0.007 inch or larger (100 mesh). Grit removal, compared to other unit treatment processes, is quite economical and employed to achieve the following results:
01. Paper Industry - NITE
www.nite.go.jpThe processes of pulp derived from wastepaper can be divided roughly into four parts: (1) defiberization, (2) dirt removal, (3) deinking, and (4) bleaching. While paperboard manufacturing only requires the processes of (1) and (2), paper manufacturing requires (1) through (4) to satisfy quality requirements. (1) Defiberization process
