Lessons Learned
1.
Lessons Learned about the Operation of the Equipment:
Operational difficulties prevented an effective capture zone.
Heat tracing was inadequate in original design; oil/water separator experienced icing problems
during shut downs.
Controls must be readily accessible.
Sampling ports must be located at treatment plant to enable quantification of system
performance.
The exhaust pipe on the oil and water separator must allow gases to release.
Roof over treatment plant would have decreased downtime.
Significant attention must be payed to prevention of fouling.

Why was the Technology Successful?
3.
Why was the Technology Unsuccessful?
Operational problems prevented long-term operation, so zone of influence was reduced.
Could not properly access system performance because of inability to take samples.
