High Efficiency RO/DI Systems

So I switched out my 150 gpd flow restrictor for a 75 gpd flow restrictor using my BRS 150 gpd 98% rejection membrane. I always use a bit of hot water in with the cold water so the input temperature is about 70 degrees. I just measured the good:waste and am getting 1:1.75. I previously measured the output of my 150 gpd membrane at about 120 gpd (tap produces 62 psi), and with the 75 gpd restrictor I am getting much faster output of good water. I should measure it. I am also still achieving 0 tds in the good water.

I am saving myself a TON in water, not only am I not using 3/4 of the water for waste, but the amount of time needed to make 50 gallons of water is significantly less.

I am currently manually flushing the membrane for about 1 minute every hour. I plan to get an auto flush kit in the near future.

I am interested to see how long the membrane lasts run in this manner. I tested the tds coming out of the membrane and will compare in a few months if the membrane lasts that long. Haha!
