Product Water

• Minimum Salt Rejection: 99.65%
• Minimum Product Flow Rate: 7,800 gpd (29.5 m³/d) for TML20D-370

Operating Limits

• Maximum Operating Pressure: 600 psi (4.1 MPa)
• Maximum Feed Water Temperature: 113 °F (45 °C)
• Maximum Feed Water SDI₁₅: 5
• Feed Water Chlorine Concentration: <0.1 ppm
• Feed Water pH Range, Continuous Operation: 2-11
• Feed Water pH Range, Chemical Cleaning: 1-13
• Maximum Pressure Drop per Element: 15 psi (0.10 MPa)
• Maximum Pressure Drop per Vessel: 50 psi (0.34 MPa)

Operating Information:

• Elements are wet tested and stored in a 1% sodium bisulfite solution or tested feed water solution, then vacuum packed.
• For short-term storage or shutdown, it is recommended to immerse elements in a protective solution of 500-1,000 ppm sodium bisulfite (food grade) in permeate.
• Free chlorine and other oxidizing agents must be removed from the feed water before operating the RO system to prevent membrane oxidation.
• Permeate from the first hour of operation shall be discarded.
• Use of chemicals incompatible with the elements will void the Limited Warranty.
