पिकअप की उपलब्धता लोड नहीं हो सकी
INDION® FFIP is a premium Type I strong base, unifunctional anion exchange resin supplied in the chloride (Cl⁻) form. It is manufactured using a styrene-EDMA copolymer matrix with benzyl trimethyl amine functional groups and features an isoporous bead structure that provides excellent ion exchange efficiency and mechanical stability.
The resin has very high basicity, making it highly effective at removing weak acids such as silica and carbon dioxide, in addition to strong acid anions. INDION® FFIP is recommended for use in two-stage, multiple-stage, and mixed-bed deionization systems where high-quality deionized water with extremely low residual silica is required.

🔧 Installation & Operating Guidelines
- Install the resin in a clean anion exchange vessel equipped with a suitable underdrain system.
- Backwash the resin before commissioning to classify the resin bed and remove fine particles.
- Regenerate the resin using an appropriate sodium hydroxide solution as specified by the system design.
- Operate within the recommended temperature limits based on the ionic form of the resin.
- Ensure feed water is adequately pretreated to minimize fouling from suspended solids and organics.
- Avoid continuous exposure to free chlorine and other strong oxidizing agents.
- Follow the equipment manufacturer's recommended operating and regeneration procedures.
- Monitor treated water quality regularly to determine regeneration intervals.
⚙️ How It Works
INDION® FFIP removes dissolved anions through the ion exchange process. As water passes through the resin bed, negatively charged ions such as chlorides, sulphates, nitrates, bicarbonates, silica, and carbon dioxide are exchanged with hydroxide (OH⁻) ions during operation. These hydroxide ions combine with hydrogen ions released from the cation exchanger to produce highly purified water.
Its Type I strong base functional groups provide superior removal of weakly ionized contaminants such as silica and carbon dioxide, making the resin ideal for producing very high-purity deionized water.
🥽 Safety & Handling
- Store the resin in its original sealed packaging.
- Never allow the resin to dry during storage.
- Keep the resin moist using clean demineralized water if necessary.
- Store in a cool, shaded location between 20°C and 40°C.
- Handle sodium hydroxide and other regeneration chemicals using appropriate personal protective equipment (PPE).
- Prevent eye and skin contact with regeneration chemicals.
- Follow standard industrial safety practices during handling, storage, and regeneration.

⚠️ Limitations and Precautions
- Maximum operating temperature is 60°C in the hydroxide form and 90°C in the chloride and other forms.
- Free chlorine and other strong oxidizing agents should be absent to prevent resin degradation.
- Resin should never be allowed to dry during storage or operation.
- Approximately 10–15% volume expansion occurs during conversion from chloride to hydroxide form; vessel design should accommodate this expansion.
- Proper pretreatment is recommended to minimize fouling from suspended solids and organic contaminants.
- Regular regeneration is essential to maintain high silica removal efficiency and overall resin performance.
- Performance depends on proper system design, operating conditions, and regeneration practices.
