Model Membrane Surface Area Avg. Permeate Flow  Stable Rejection Rate Minimum Rejection Rate
ULP1812-50 4.4ft² / 0.41m² 50GPD / 0.19m³/d 97.5% 96.0%
ULP1812-75 5.0ft² / 0.46m² 75GPD / 0.28m³/d 97.5% 96.0%
ULP1812-100 6.0ft² / 0.56m² 100GPD / 0.38m³/d 95.0% 93.0%


Please Note: Membrane performance is dictated by several variables, most importantly are; incoming water TDS levels, pressure, and temperature. The membrane outputs stated above are based on test conditions which are;

Concentration of Solution (NaCl) = 250ppm

Water Pressure = 60 psi / 0.41MPa / 4.14 Bar

Temperature = 25°C

The membrane elements must be stored in a cool and dry place, away from direct sunlight. Do not expose to temperatures above 45°C
