Regeneration of steelworks spray-roasting pickling solutions, comprises filtering settled solution using transverse-flow microfilter

摘要

Pickling solution is stilled in a sedimentation tank. It is then purified in a transverse-flow microfilter at 10-55degreesC. The pickling solutions are introduced into a stilling vessel, then pre-cleaned in a transverse flow microfiltration plant. Processing follows in an acid regeneration plant, in accordance with spray roasting principles.
