ABSTRACT:
Solids from a liquid containing heavy metals are filtered by first degassing the solids-laden liquid and then subjecting the degassed liquid to sedimentation to remove large particles and subsequently intermediate size particles. The suspension of fine particles is then passed in counterflow to a moving bed of granulate, especially black peat, to which the particles tend to adhere externally and internally. Clear liquid is removed from the top of the moving bed and the granulate is washed after being withdrawn from the bottom of the bed and is recycled to the moving bed.
