Niter and RO System

Hello Everyone,

I am posting from PEI, my family and i have only been making syrup for about four years so we are still learning. we tap about 150 trees and this year we added a RO system and an urn with a thermostat for bottling. We have run into a problem with niter that we have not experienced before. We do a lot of filtering and in the past had no issues making a really clear bottle of syrup. Now since we added two new elements we have a niter issue. We strain the sap from the woods, we filter with a pre filter and felt cone filter and two additional layers of felt filters as it comes out of the evaporator, we finish on the stove and then filter again with pre filter, felt cone filter and two extra layers of felt filters and then one last time through a piece of pre filter before it goes into the bottle. This is in addition to the filter and four membranes from the RO system. So i am not sure how the niter can get through all of that. We are new to RO systems and this is our first try so we suspect it maybe connected to the level of sugar and how long its in the evaporator, or we have no real idea. Does anyone have any suggestions on what is happening? and how to fix it?


I thank you in advance for your time and expertise.
