Here are two photos of our system.

The photo on the right shows the receiving tank from the woods. It is the tank one the right and holds 260 gallons. The RO draws from this tank and puts the concentrate into the tank the RO is sitting on. This tank is 160 gallons. The permeate is going into the fitting just above the RO on the left wall. In the other room we have two 275 tote tanks for permeate. In this case the concentrate is being put into the fitting on the right wall. This is a PVC pipe leading to an elevated 100 gallon tank which feeds the evaporator.

The second photo shows the evaporator with the feed tank behind and above it. In the upper right portion you can see the white PVC pipe which feeds the tank from the RO.

This system allows us to run many combinations of concentrate. Normally we run the sap through the RO and into the tank below it. Then we run it a second time to the feed tank. As the sugar content drops we can recirculate it in the tank below the RO before pushing it up to the feed tank.

If you need and thing specific for images or measurements let me know. This year we are going to knock out the wall being the two tanks and install a 788 gallon tank in place of the 260 gallon tank. This is in preparation for our expanded taps, adding 400 to have 800 taps.
