Tetrakis (hydroxymethyl) phosphonium sulfate (THPS)

Colorless odorless viscous liquid biocide

Tetrakis (hydroxymethyl) phosphonium sulfate (THPS) is a water-soluble, white crystalline solid that is odorless. It is a highly effective biocide and has excellent efficacy against bacteria, fungi, and algae. THPS is a versatile compound and is commonly used in industrial water treatment, oil and gas production, and as a preservative in the textile, leather, and paper industries. Additionally, it is used as a flame retardant in a variety of materials, such as textiles, plastics, and coatings.

Energy Sector

Tetrakis (hydroxymethyl) phosphonium sulfate (THPS) is used in the energy sector primarily as a biocide to control microbial growth in oil and gas production, drilling, and pipeline operations. It is an effective alternative to traditional biocides like glutaraldehyde and formaldehyde, as it has a lower environmental impact and is less toxic. THPS can also be used to control corrosion in oilfield equipment and pipelines, and as a clay stabilizer in drilling fluids to prevent formation damage and maintain wellbore stability.

Water Treatment

Tetrakis (hydroxymethyl) phosphonium sulfate (THPS) is used as a biocide in water treatment. It is effective against a wide range of microorganisms including bacteria, algae, fungi, and viruses. THPS is also used as a scale and corrosion inhibitor in water treatment applications, particularly in cooling towers and boilers. Additionally, it can be used as a preservative in pulp and paper mills, and as a flame retardant in the textile industry. THPS is preferred over other biocides due to its low toxicity, low environmental impact, and biodegradability.

Pulp & Paper

Tetrakis (hydroxymethyl) phosphonium sulfate (THPS) is commonly used in the pulp and paper industry as a biocide and microbicide to control microbial growth and slime formation in paper mill systems such as white-water systems, stock pulp, and paper machine systems. THPS can also be used as a preservative to prevent bacterial and fungal growth in paper products during storage. Additionally, THPS can help reduce the number of sulfur-containing compounds and the formation of hydrogen sulfide gas in paper mill wastewater.
