Green steel trial at the wastewater plant
Summary
The plant is only the second city in the country trialing 'green steel' — steel mill slag — to replace ferric chloride for phosphorus removal. Sixty days in, the plant is running better than ever with a third less chemical, and staff built the feeder in-house for $2,150 instead of a $100,000 system.
