Reverse Osmosis (RO) System

October 1, 2018

Reverse Osmosis is a process typically used for water purification. A semi-permeable membrane is used to separate water from sugar, minerals, and other impurities. In the maple industry we use reverse osmosis systems, but instead of keeping the purified water, we keep the concentrated sugar, minerals, and other impurities as concentrated maple sap to finish boiling into maple syrup. Memprotec RO machines are specifically designed for processing maple sap with the best membranes, properly designed pumps for maximum output, and easy cleaning.

If your sap has less water in it, then less boiling is required to get syrup; therefore increasing your efficiency. A reverse osmosis system can effectively reduce your boil time by 60 to 75% based on brix concentration.1
