Title: Anaerobic and Aerobic Bacteria in Electrocoat Systems

Description:

Bacteria continues to be a growing concern in electrocoat systems. It's important to be able to distinguish anaerobic from aerobic bacterial outbreaks as well as understand the challenges they present and how to eliminate a contamination.

Type: Learning Station VI: Process Improvement

Abstract:

Bacteria contaminations of electrocoat systems are continuously rising as newer paint technology calls for an overall reduction in VOC’s and heavy metals as well as higher operating temperatures. While most discussions regarding ecoat bacteria have revolved around more common aerobic bacteria, there has been far less emphasis on the elusive anaerobic counterpart, which has historically been more difficult to recognize and remove from an electrocoat system. The primary difference between these two classifications is that aerobic bacteria can only survive in the presence of oxygen while anaerobic bacteria grow in the absence of oxygen. Once aerobes use up available oxygen during a bacterial outbreak, anaerobes proliferate. This presentation addresses the challenges of both aerobic and anaerobic bacteria in electrocoat systems and aims to provide a structured approach toward identifying and eliminating both types of contamination.
