Technology welcomed by galvanisers

ABR Acid Regeneration Technology Welcomed by Galvanisers


Disposal of spent pickle liquor (SPL) from acid baths is proving to be increasingly costly for galvanisers. ABR has tested samples of this liquor and regenerated acid with the additional benefit that zinc is deposited on the cathode of the 'black-box' cell. During a recent visit from a leading galvanising group, ABR demonstrated the process, cleaning up the SPL for easy disposal and providing valuable products for re-use. The prospective client considered that a critical advantage for galvanisers is that continuous feed from the acid tank to the 'black box' ensures cycle times for pickling are optimised, significantly increasing production flow.
