im in the garbage removal industry,bout 15 years ago we did a job at a chrome plating place,they gotta de sludge and have neutralized their tanks every so often,it was done by an outside company we supplied the bins,was three x 3 cubic metre bins it cost em 25,000 bucks,we didnt empty the bins straight away they got sat down and stored for a coupla weeks for transport and time reasons,the bins have drain holes for rain,these bins leached all this copper green sulphate looking #$%* out of them and once emptied ive never seen heavy solid steel rust so fast?chrome is nice,the process is toxic.
