Product features: 1. Effective control of inorganic fouling in a large concentration range. 2. Does not aggregate with iron-aluminum oxide and silicon compounds to form insoluble matter. 3. Particularly effective for controlling iron, aluminum and heavy metal contaminants. 4. Can effectively control the polymerization and deposition of silicon. 5. Can be used for reverse osmosis CA and TFC membranes, nanofiltration membranes and ultrafiltration membranes. 6. Excellent solubility and stability.
