Usage of Tetrakis(hydroxymethyl)phosphonium sulfate
1. Oil and gas industry
Serve as non‑oxidizing biocide for injection water, produced water, drilling fluid and pipeline systems. It efficiently kills sulfate‑reducing bacteria (SRB), penetrates biofilm, mitigates microbial‑influenced corrosion (MIC) and reservoir souring. Meanwhile, it scavenges hydrogen sulfide (H₂S) to control toxic hazards in oil‑gas production.
2. Industrial circulating water treatment
Broad‑spectrum biocide for cooling towers, recirculating process water and storage ponds. It suppresses bacteria, algae and slime fouling. Good compatibility with scale inhibitors and corrosion inhibitors. Fast biodegradability reduces environmental discharge risks.
3. Textile finishing
Durable wash‑resistant flame‑retardant finishing agent for cotton and other cellulosic fabrics. Applied together with urea or amine curing agents to achieve permanent flame‑retardant performance for textiles.
4. Pulp and paper manufacturing
Act as biocide and slimicide for pulp process water. Restrain microbial slime accumulation, prevent paper breaks and surface defects, stabilize pulp quality during paper‑making procedures.
5. Aquaculture industry
Water quality improvement bactericide for aquaculture ponds. Inhibit harmful bottom‑layer bacteria, degrade toxic metabolites and optimize substrate environment for fish and shrimp farming.
6. Leather processing
Preservative and processing auxiliary for leather tanning. Effectively suppress mold and bacterial spoilage of raw hides.
