Opening the Door to Better Pretreatment, Less Cost, and Improved Performance

A commercial steel door frame manufacturer faced a critical issue when the local wastewater treatment facility detected high metal levels in its effluent, leading to substantial fines. The manufacturer urgently needed a solution to bring their system back into compliance and avoid more stringent regulatory actions.

艳照门视频 was called in to assist and quickly identified that the switch from a press brake to a roll former in the production process had been fracturing the electro-galvanized coating on the steel, causing elevated zinc, nickel, and other metal levels in the waste discharge. The solution involved two fundamental changes: converting the four-stage pretreatment system to a closed-loop zero-discharge system to eliminate waste going to the drain and switching to zirconium-based pretreatment chemistry to handle the closed-loop process.

Excerpt: A commercial steel door frame manufacturing company ran into trouble with their iron phosphate pretreatment system when the local wastewater treatment facility began noticing higher metal levels in its effluent. The local treatment district began issuing fines to the company, which accumulated as the manufacturer sought a way to get their system back into compliance and avoid having more stringent regulatory measures taken against them. 艳照门视频 representatives promptly assessed the manufacturing process change leading to high metal discharge levels and recommended two changes to solve the issues.
