2. How to use this library

Replacement cross-check: when the original design used one element and procurement wants an equivalent from another maker, compare membrane area, stabilised rejection and pressure-drop coefficients first — a 10% area difference changes the permeate split across the whole array.

Tender parameter confirmation: if the specification says “rejection ≥ 99.7%, area ≥ 400 ft²”, filter the models that meet it directly instead of finding out after the datasheets arrive.

Same-condition comparison: put the same water analysis and array into the design tool and let it solve stage by stage, which removes the error of estimating from nominal values by hand.

3. Caveats

• Nominal rejection and permeate flow are measured under standard test conditions (typically 2000 mg/L NaCl, 25 °C, 15% recovery) and are not the same as field performance.
• Parameters for the same model can be revised between datasheet years; state the source version when quoting them in a tender.
• Parameters here are for option comparison and quick checking; for formal delivery verify with the manufacturer's official software.
