Alberts Filter 150 GPD RO, Reverse Osmosis with Housing, Wrench, 1/4" Quick-Connect Fittings, Check Valve, Replacement for Under Sink Home Drinking RO Water Filter System

Used three 150 GDP in series to process 2.2% maple sap prior to boiling. 50% water removal, 80 psig back pressure, flow is 5 gallons of sap in 20 minutes. Two passes removes a total of 75% water and makes 8.5 to 9% sugar content concentrate.

I use this downline from a dual filter system and installed a flow regulator on the wastewater outlet, I achieve 4ppm water. I filled up a 5-gallon jug in about 90 minutes.

Been using this for a year now. I run my RO at 100 psi. My tds meter coming out reads 1 to 3 ppm most of the time it reads 1.

This is a great product, I upgraded to two membranes to increase my RO output and decrease the wasted water. Working Great!

The RO filters are handling making r/o water really well
