The Acid Processor recycles millions of gallons per year of spent pickle liquor and rinse water allowing the hydrochloric acid to be used over and over again. Several thousand tons of iron oxide is recovered as a by-product each year and sold.
The Chrome Recovery Unit (CRU) recycles chromium contaminated rinse water and returns hundreds of thousands of gallons per year of chromium solution to the ETL lines. The CRU also recycles 100 gpm of de-ionized and cooling water to the ETL lines.
The Oil Separation Unit (OSU) processes 200 gpm of used rolling solution from the production lines. This process reclaims tens of thousands of gallons of oil per month which is then sold.
