CDL 600 RO question

[mainebackswoodssyrup]

Question for the guys out there who run a CDL 600 RO with lower side tap counts/sap runs….
How much sap do you need in each run to generate enough permeate to rinse and soap wash these RO’s? 600 gallons?
Our average sap run when we get full vacuum should be at least 500-700 gallons with peak runs probably 1,000 or more. It’s the early/small runs I worry about. I am trying to find a way to get 10-12% in one pass instead of 6-8% with a hobby RO. We would squeeze the 600 as hard as we can. I’d prefer not to recirculate with a hobby RO although I realize that probably fits our operation better. I know Lapierre has the turbo 250’s that might do it but I really am cautious of the local support from CDL that is 25 minutes away.
We have planned for an 800 gallon permeate tank, originally expecting to run a 250 RO but we also have a 1200 gallon tank we could use.
