Abstract
An installation for the treatment of metals pickling solutions is disclosed. The invention provides for solutions to be treated by electrodialysis in a tank which is divided up to form sets of three compartments. Anode and cathode compartments in the form of removable cases are arranged alternately with spaces therebetween defining central compartments. In use, according to a preferred method of the invention, anolyte flows through the anode compartments while the picklng solution flows through the cathode and central compartments. Flow through the compartments may be either in series or in parallel.
Claims10
An installation for treatment of solutions used for pickling metals which comprises:
- a treatment tank,
- a plurality of sealed cases comprising anode compartments suspended in said tank, each of said anode compartments comprising a pair of longitudinal side walls extending into said tank and containing an electrical anode, at least one ion exchange membrane mounted on each of said side walls, each of said anode compartments being removable from said tank,
- a plurality of sealed cases comprising cathode compartments suspended in said tank and spaced apart from said anode compartments, each of said cathode compartments comprising a pair of longitudinal side walls extending into said tank and containing an electrical cathode, at least one ion exchange membrane mounted on each of said side walls, said cathode compartments being removable from said tank, and
- a plurality of central compartments within said tank, each of said central compartments being defined by one side wall of an anode compartment and one side wall of a cathode compartment.
