This post will walk through the basic principles of reverse osmosis for maple sugaring, general design considerations for a DIY hobby unit, and an overview of a DIY portable hobby RO unit. I use Membrane Solutions 400 and 500 gpd membranes and am incredibly happy with their performance and quality. Here is a link to the Membrane Solutions Amazon store : General Principles: Reverse osmosis is a process by which pure water (called permeate) is created through filtration at the molecular level through semi permeable membranes, facilitated by an applied pressure (normally from a booster pump). This removes unwanted ions, particles, molecules, and even bacteria from the water output (permeate). The "waste" output (called concentrate) is full of all the items removed from the feed water. In maple sap applications the concentrate is what we are keeping and leads to less water to boil out of the sap, or, in other words, a higher sugar concentration on a volumetric basi
Building a temperature controlled maple tubing vacuum system For the 2021 season we converted our operation to 3/16" tubing and built a temperature controlled vacuum system that uses a diaphragm pump. The setup worked amazing and we averaged over 1 gallon of sap per tap each day, totalling 19 gallons of sap per tap and 0.275 gallons of syrup per tap on the season. In 2022 this system averaged over 0.35 gallons of syrup per tap on the season. We used Leader clear check valve spiles with approximately 100 taps on a total of 6 lateral lines of tubing (~16 taps per line). Our lateral lines have fairly good elevation drop to them (over 100 feet total and at least 10 feet from the final tap in most cases). This resulted in good natural vacuum and increased our sap yields. Additionally, the small diaphragm pump induced additional vacuum in the lines, further increasing sap yields. We consistently saw approximately 29 inHg of vacuum at the top of each line and 23 inHg at the pump
