Membrane-specific scale inhibitor FRA1100（Concentrated 8 times）
FRA1100 Scale Inhibitor (an 8× concentrated formulation worked as a direct replacement for PTP0100) is a high-efficiency scale inhibitor and dispersant for feed waters with elevated concentrations of metal oxides, silica, and scaling salts (e.g., calcium carbonate, calcium sulfate). It delivers robust scale control without forming insoluble precipitates or foulants in the presence of residual coagulants, aluminum/iron ions, or silica species. When dosed upstream of reverse osmosis (RO) and nanofiltration (NF) membrane systems, FRA1100 effectively protects membrane elements, extends service life, reduces cleaning frequency, and lowers operational and maintenance costs.
