Reverse Osmosis (RO) is a process typically used for water purification: a semi-permeable membrane is used to separate water from salt, sugar, minerals, and other impurities. In the maple industry we use RO systems not to obtain purified water, but to concentrate the sugar in the maple sap. This is then finished by boiling the sap into maple syrup, at considerable energy savings (upwards of 90%). Our R/O machines are specifically designed for processing maple sap with the best membranes. And their pumps are properly designed for maximum output and easy cleaning. Leader Evaporator also carries a full line of supplies to clean and maintain RO machines.
