SWG Operation - Lessons Learned

Thanks Pat,
That's a great post. I remember vaguely the lost version so I printed this new one. Chemistry isn't my forte but your explanation is one that I get.

Question: When the first cell "started to die", what was the indication? The reason I'm asking is my cell output seems to go up every year with the other variables the same. I assumed (incorrectly?) that it would suddenly die.

Thanks, Tony

You will find that the DC volts go up and the DC amps go down, indicating a higher resistance between the membranes as the coating wears out. The chlorine output starts to go down as well.

In your case, you appear to have a cell that seems to "rejuvenate" itself. I would expect that might happen if you acid wash the cell at the end of the season, but I suspect something else might be happening. It should lose efficiency as it gets to the end of its life.

Hope this helps.

Well, when I typed my output goes up I should have said output SETTING......ahhh....what a difference a word makes.

Thanks for the info Pat, I'll have to keep an eye on it.
