I set my WJ bottler to run at 185-187. There seems to be no issue that way.
Back before I had my filter press, I used an orlon filter topped with 5 or 6 pre-filters. As the flow got slow, I carefully removed the top pre-filter and then I hung it from above to drip into the next one. As I finished I usually had 2 or 3 pre-filters left, but it would not be an issue unless you get down to no pre-filters.
Some producers use DE with flat or cone filter set-ups. They say it helps. The science of how it works is that the DE can not pass thru the orlon filter, so it forms a filter cake, it is that filter cake that actually does the filtering. DE is one of the best filters you can get. When the filter cake forms, it traps the sugar sand throughout the cake, not just on the surface like it does without the DE. Then the DE is the filter.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
