Selecting the correct membrane for your Hydrotech HT101 or 123 Series reverse osmosis system:


The easiest way to determine which membrane is right for your system is to match the color of the tape band wrapped around the membrane. TFC membranes will have a yellow or green wrap, along with the colored tape to identify the permeate flow rate. Use the chart below to select the correct membrane.
