Nacl concentration: 250 ppm. recovery: 15%. For this system, capacity is 100 gallons per 24 hours. that is about 4.2 gallons pure water per hour if above work condition. Please refer. **Q: What does this system need to run? What does it hookup to?** A: FEED WATER PRESSURE:40 - 100 PSI (If less 40 psi, we must to add booster pump ,or else, system can not work); 60psi is best work pressure. if too less, pure water capacity will be less.
