F-191 RO Antiscalant and Dispersant – The Advanced Solution for Long-Lasting Membrane Performance

Product Performance

F-191 RO Antiscalant and Dispersant is a high-performance chemical additive engineered for reverse osmosis (RO), nanofiltration (NF), and ultrafiltration (UF) systems. Specifically designed to prevent scale deposition and membrane fouling, this product ensures superior system efficiency and extended equipment life in both industrial desalination そして drinking water purification processes.

Outstanding Scale Inhibition Power

F-191 demonstrates exceptional performance in controlling and preventing the buildup of common scales such as calcium carbonate, calcium sulfate, barium sulfate, and strontium sulfate, even under high salt conditions. Its advanced formula enables reliable operation even when the Langelier Saturation Index (LSI) reaches 3.0 — maintaining optimal membrane flow and minimizing downtime.

By effectively dispersing inorganic particles, F-191 keeps the RO membrane surface clean, reducing the need for frequent chemical cleaning. This not only improves overall system reliability but also helps maintain consistent water flux density そして permeate quality.

Broad Water Compatibility and Enhanced Stability

F-191 is suitable for a wide range of water types — including brackish water, high-salinity seawater, and potable water systems. It serves as both an antiscalant そして anti-choking agent, offering excellent resistance to ferric oxide そして aluminum oxide deposits. Unlike traditional polyphosphate-based inhibitors such as Calgon (SHMP), F-191 provides improved thermal stability, longer-lasting performance, and higher economic efficiency.

It also supports system operation without the frequent need for acid dosing, reducing both environmental impact and maintenance costs. This makes F-191 an ideal choice for eco-conscious water treatment operations そして municipal drinking water facilities.

Economic and Operational Benefits

Using F-191 significantly reduces scaling-related maintenance and cleaning downtime, extending the lifespan of RO membranes and associated pipelines. The product’s stability and solubility ensure precise dosing and consistent performance even in complex treatment environments.

Compared to conventional inhibitors, F-191 delivers:

• Higher scale inhibition efficiency across multiple ions
• Lower chemical usage and overall cost per treated cubic meter
• Improved operational reliability and reduced membrane replacement frequency
• Safer operation with minimized acid requirement

Technical Specifications

Usage and Application

For maximum efficiency, F-191 should be injected before the static mixer or cylindrical filter in the RO system. The recommended dosage is 1–4 mg/L, adjusted based on feed water analysis and system parameters. F-191 can be used directly or diluted with RO permeate or deionized water.

⚠️ Note: Both overdosing and underdosing can negatively affect RO membrane performance. For accurate dosing recommendations, consult your WaterCareChem technical expert.

Packaging and Storage

F-191 is available in:

• 200L plastic drums
• 1000L IBC tanks
• Custom packaging available upon request

Store the product in a cool, ventilated area, away from direct sunlight. Under proper conditions, F-191 maintains stability for up to one year.

Safety and Handling
