Recognize the evidence
Review voltage-current behavior, process conditions, dust characteristics and outlet performance together. No single symptom confirms the cause in every application.
Evaluate corrective options
Possible responses include conditioning, temperature adjustments, operating changes and electrical or mechanical upgrades. Their suitability depends on the dominant mechanism and process constraints.
Compare on a consistent basis
Define the starting flow, particulate loading and electrical conditions. Separate improved collection efficiency from reduced outlet mass, and state the basis for any claimed improvement.
