eNPure...Your Single Source Solution for:
Reverse Osmosis Iron Fouling/Scalant Control
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.
- 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
The adverse effects are decreased reverse osmosis recovery rates,
increased dosing amounts of anti-scalant, and more frequent membrane cleanings and replacements.

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.
