🧪 FilmTec / Hydranautics (Membrane Flux 14-18 GFD, Permeate Recovery 75%-85% & TDS)

Industrial Reverse Osmosis (RO) Calculator

Size multi-stage industrial Reverse Osmosis (RO) skids with 8-inch spiral-wound polyamide elements (FilmTec / Toray): calculate membrane permeate water flux (14 to 18 Gallons per Sq Ft per Day GFD), calculate recovery ratio (75% to 85% with 2:1 array staging), verify salt rejection (>99.5% TDS reduction), and water treatment contractor margins.
