Tetrakis Hydroxymethyl Phosphonium Sulphate (THPS) 75%
Product Overview:
THPS (tetrakis hydroxymethyl phosphonium sulphate) is a broad-spectrum biocide used extensively across upstream and midstream oilfield and industrial water treatment applications. It is commonly employed to control bacterial growth in drilling and production fluids, preventing biofouling, corrosion, and reservoir souring caused by sulfate-reducing bacteria. Additionally, it serves as a biocide in industrial water treatment systems, including cooling towers and pulp mill process water, where consistent microbiological control is essential. THPS is also utilized in fracturing fluid formulations requiring an effective, readily biodegradable biocide. Furthermore, it finds applications in general oilfield chemical treatment programs requiring rapid bacterial kill.
