I have two 60 gallon barrels for permeate from 100 trees on 3/16 vacuum. Having all the permeate you can for flush, wash, rinse purposes is a good idea.
A few questions:

For the first flush prior to processing the sap, I will be using filtered and UV’d lake water.
How many gallons of that water will I need to do a proper initial flush?
Will all of that be waste after it has flushed the membranes?

Let’s say the first time I run the RO is with 50 gallons of sap, in the perfect world, it will produce 25 gallons of permeate.
Is that enough for the flush?
Is that permeate waste after the flush or can it use it again for another flush?

I guess after the flush, you have to wash it with a combination of either permeate and soap or water and soap. Is that all waste? How many gallons of soap and water/permeate is need for the soap wash?

Thanks
