Metal Finishing Workshops
The following are sample outlines of the workshops used in the Metal Finishing P2 Project:
Dragout Reduction and Rinse System Design
- Measure dragout on a plating line
- Understand rinsing concepts
- Learn best practices for reducing dragout
- Use spray rinses to reduce dragout
- Use conductivity control systems to reduce rinse water use
Environmental Management and Process Efficiency
- Results of on-site demonstration projects on electrowinning and replacing vapor degreasers with aqueous units
- Two dragout reduction training tools
- Environmental management systems (EMSs) and their relationship to process assessment and control
Chrome Emission Regulations and Reject Rate Reduction (June 1996)
- Impacts of chrome emission regulations on plating industry
- South Coast Air Quality Management District Chrome Emission Regulations
- Reject rate reduction and Microplate Company's external cooling unit case study
Measurement and Monitoring (March 1997)
- Where to focus measurement and monitoring efforts
- Important facility-wide process parameters
- How to measure process-specific parameters such as dragout and rinse water flow
- Case studies on tank layout and material balance
Best Practices for Line Operators
Is intended to train line operators and others about the following
topics:
- How operators impact process operations, efficiency, and waste generation
- How to rack and handle parts to minimize dragout loss and rinse water use
- How to train others on proper operation techniques
Pollution Prevention Technologies
- Process controls that support P2 technologies
- Bath contaminant removal technologies
- Chemical recovery and rinse water reuse technologies
