We've got a cdl hobby 250 thats performing like a single post 125. The saps been cold but shouldn't make that much a difference. The membranes are a season and a half old. We wash it like normal. Any ideas?

What are the flow rates when you benchmark the RO? If the benchmark has dropped by 15% of the flow when new, and the flow doesn't return after a regular soap wash you might need to do an acid wash on the membranes. I noticed my RO flow rates were dropping off and that is my plan once I get sap to concentrate and permeate to rinse with.

When it was normal it put out 2 gpm each for concentrate and permeate. Now its at around 1 gpm each. How do you do an acid wash? The same as a soap wash? What kind of acid?

There should be something in the manual about acid washing. Generally citric acid is used to drop the ph and then circulated and sometimes left to sit for a period of time. This dissolves the minerals that get caught in the membrane. A soap wash is alkaline and meant for removing biological material not mineral.

1. Do a soap wash then add clean water to wash tank.
2. Add Acid; follow directions on ACID WASH JAR.
3. Recirculate for 5 minutes.
4. Stop and let set 24-48 hrs, (up to 4 weeks
after season), do not freeze. Once acid wash is in the membranes, drain the wash tank and rinse it with water.
5. Now do a soap wash
6. Then do a 10 minute cold water rinse
7. Change pre-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.
Thanks for the responses. So where do you get the acid? Is that a maple related thing or do you get it somewhere else? Sorry for the dumb Qs.

I buy mine on amazon. Much cheaper than maple suppliers. https://www.amazon.com/gp/aw/d/B00GN...o_pop_mb_pd_t1Originally Posted by Asa Matras

I was going to reply to this thread last night but my container of citric acid is in the sugar house and I had been out in the snow too much to go out again. What Dave said is the way to do it and the closer that you can get to the 48 hours the better. Have plenty of permeate on hand to do the washes and rinses. I bought my citric acid from Bascom's.

My tank holds about 15 gallons. I put in 2 Betty Crocker frosting containers to get pH to about 2
