Design Guidelines for VariousWater Sources:

  • Wastewater Conventional (SDI < 5) - 8–12 gfd
  • Wastewater Pretreated by UF/MF (SDI < 3) - 10–14 gfd
  • Seawater, Open Intake (SDI < 5) - 7–10 gfd
  • Seawater, Beach Well (SDI < 3) - 8–12 gfd
  • Surface Water (SDI < 5) - 12–16 gfd
  • Surface Water (SDI < 3) - 13–17 gfd
  • Well water (SDI < 3) - 13–17 gfd
  • RO permeate (SDI < 1) - 21–30 gfd

Saturation Limits (Using Antiscalants) *:

  • Langlier Saturation Index (LSI) <+1.5
  • Stiff and Davis Saturation Index (SDSI) <+0.5
  • CaSO 4 - 230% saturation
  • SrSO4 - 800% saturation
  • BaSO4 - 6,000% saturation
  • SiO2 - 100% saturation

*The above saturation limits are typically accepted by proprietary antiscalant manufacturers. It is the user’s responsibility to ensure proper chemical(s) and
concentration are dosed ahead of the membrane system to prevent scale
formation anywhere within the membrane system. Membrane elements fouled or damaged due to scale formation are not covered by the limited warranty.
