Reverse Osmosis Iron Fouling/Scalant Control
![](images/pix-ro-program1.jpg)
eNPure's AS-156 inhibits scale deposition and biological fouling in Reverse Osmosis feed waters containing high levels of soluable iron (Fe+2). Increase Reverse Osmosis recovery rates, decrease
membrane cleanings, and membrane replacements with AS-156.
APPLICATIONS
- Surface waters with variable turbidity
- Ground waters with high fouling tendencies
When ferrous iron is present in
source water, it promotes biological
fouling and inorganic scaling of
reverse osmosis membranes.
Iron inhibits the performance of
most anti-scalants, which causes
increased dosing levels to prevent
the precipitation of calcium and
magnesium salts.
The adverse effects are decreased
reverse osmosis recovery rates,
increased dosing amounts of
anti-scalant, and more frequent
membrane cleanings and
replacements.
DESIGNED FOR FEED WATER WITH MODERATE LEVELS
OF IRON UP TO 5 PPM Fe+2 (FERROUS IRON)
CONTROLS CaCO3, CaSO4, BaSO4, SrSO2,
AND SILICATE SCALE
DISPERSES METAL OXIDES AND INORGANIC
PARTICULATES LIKE SILT AND CLAY
STABILIZES METAL IONS TO PREVENT METAL HYDROXIDE,
METAL PHOSPHATE, AND METAL SILICATE PRECIPITATION
INCREASES REVERSE OSMOSIS RECOVERY RATES
DECREASE AMOUNT OF MEMBRANE CLEANINGS
AND MEMBRANE REPLACEMENTS
INCREASED REVERSE OSMOSIS UPTIME
LOWER DOSING LEVELS THAN
OTHER ANTI-SCALANTS
eNPure's water treatment experts can help you prevent fouling and scaling in Reverse Osmosis Systems utilizing advanced and proprietary process design and engineering.
The below graph is from a case study comparing anti-scalants available in the market, which was performed to prove the impact of ferrous ion oxidation on silica scaling in reverse osmosis systems. It shows that Enpure's AS-156 prevents almost all precipitation which causes scaling in reverse osmosis systems.
