Over the years, there have been many innovations discovered during Clean Water U sessions. September’s session at Camp Hopewell had one of the more memorable ones. It seems that one of the standard board students was frustrated trying to observe the “blue-green glow” at the ends of the ozonator lamp cartridges. Rather than staying frustrated, these students developed a prototype Ozonator Observation Hood.
Demonstrated in the photos below, the Ozonator Observation Hood allows students to observe the “blue-green glow” of the lamp cartridges under any conditions.

This innovation may not be as cool as the “Woehler/Advent Rinse Assembly” found in Appendix C of Volume 4 of the handbook, but it may help out as you train your Operating Partners on how the Ozonator works.
FCI will not be stocking the Ozonator Observation Hoods any time soon, so you are on your own as far as using this in your systems.
Let the clean water flow!

My first email appears to have gotten garbled and, once sent can’t be corrected so here is the re-typed version:
The tech blog is an excellernt idea.
We have found that installing more unions, particularly at sites prone to leaking such as by threaded connectors, makes both the initial installation and later troubleshooting easier and doesn’t add much cost.
Is there a printed checklist for site inspection, for eqipment one should take as well as on-site inspection of system function?
Thanks for the question, Dan.
LWW agrees that the more unions a team uses in their system, the easier it will be to troublehoot, fix leaks, and resolve other problems.
Besides the Ozonator Checklist, the LWW Clean Water Systems Handbook does not contain any other checklists. We tried to write the instructions in short, numbered statements, so that an operator would be able to check off steps during a start-up, shutdown, or normal operations.
We have a checklist called the Sustainability Tool that is used for follow-up visits to a system. If you would like a copy of that Excel spreadsheet checklist, please let me know.
Thanks again for your questions and let the clean water flow.
