Continuous treatment of carry-over on ferrous metal workpieces |
| abstract |
FERROUS METAL-CONTAINING WORKPIECES WHICH HAVE BEEN SUBJECTED TO A PICKLING OR OTHER TREATMENT IN AN ACID BATH HAVE POTENTIALLY POLLUTING IRON SALT WASTE OR CARRY-OVER SOLUTION ON THEIR SURFACES THAT IS FULLY REACTED AND NEUTRALIZED BY A CALCIUM CONTAINING AQUEOUS CHEMICAL SOLUTION, WITHOUT FORMING UNDESIRABLE CALCIUM DEPOSITS AND WHILE ENABLING EFFICIENT PRECIPITATION OF IRON COMPOUNDS. THE WORKPIECE MAY BE SUBSEQUENTLY SUBJECTED TO A RINSE WATER WASH WITHOUT FEAR OF CONTAMINATING A STREAM IF THE WASH WATER IS TO BE DISCHARGED THEREIN. THE AQUEOUS TREATING SOLUTION IS CONTINUOUSLY RECONDITIONED AND REUSED AND SUBSTANTIALLY FULLY REMOVES, REACTS WITH OR NEUTRALIZES THE WASTE CARRY-OVER ON A WORKPIECE THAT IS BEING MOVED CONTINUOUSLY INTO AN AQUEOUS WASHING BATH. |
