Reverse Osmosis Water Management

[Nexogen]

The experience I have is empirical, I wanted RO and for the first time I bought a ready-made system. In the meantime I realized that I can build my own and back flush is good in "cleaning" the membrane. Probably going without a back flush. I saw what happens without. Nowadays, the cost of a membrane is low and you can do as you wish, which is why I chose to go with 300 ml/min restriction for 100gpd and back flush even if I have RO 3-5ppm output. In fact a membrane 400 gpd + housing costs around US$ 50 from Aliexpress, it is not expensive, for me it was important to be small.
