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.

Küllastuspiirid (kasutades antiskalante):*

Langelier'i küllastusindeks (LSI) < +1,5
Stiff ja Davis küllastusindeks (SDSI) < +0,5
CaSO₄ – 230 % küllastus
SrSO₄ – 800 % küllastus

SiO₂ – 100 % küllastus

* Need küllastuspiirid on üldiselt aktsepteeritud antiskalandi tootjate poolt.
Kasutaja vastutab sobivate kemikaalide ja nende kontsentratsioonide doseerimise eest enne membraanisüsteemi, et vältida katlakivi ja setete teket süsteemis.
Membraanielemendid, mis on kahjustatud või ummistunud katlakivi tõttu, ei kuulu garantiisse.
