Final product types

• Sweet or sour crude oil ready for refining
• Corrosion-free pipeline and process water for reinjection
• Recovered oil separated from reclaimed water

2. Industrial Paper Manufacturing—Slimicide Treatment

Pulp and paper mills use THPS-based slimicides to inhibit biological growth within white water circuits, stock preparation, and wet-end systems. The material controls bacteria and fungi that form slime deposits, protecting production lines and ensuring the surface quality of paper products. Dosing rates follow lab assay and mill audit recommendations, integrating with mill safety and effluent discharge norms.

Industry compliance standards

Typical usage ratio

• 20–300 ppm in recirculating water systems—adjusted by microbial challenge and retention time
• Evaluated by routine microbiological and deposit testing

Downstream process integration

• Dosed into headbox, white water loop, or stock feed tanks
• Blending with other papermaking chemicals prior to sheet formation

Final product types

• Food-grade packaging paper
• Printing and writing paper
• Corrugated board and tissue paper

3. Leather Processing—Tanning and Preservation

Leather tanneries employ THPS derivatives in the preservation and pre-tanning of hides. The chemical prevents biological degradation during storage and shipment, reducing the need for salt curing and minimizing environmental load. Technicians tailor the concentration based on hide thickness, process temperature, and holding duration, in accordance with global leather safety and effluent requirements.

Industry compliance standards

• ISO 5395:2017 for chemical usage in leather processing
• REACH Annex XVII (Restrictions on certain hazardous substances)
• ZDHC MRSL (Zero Discharge of Hazardous Chemicals—Manufacturing Restricted Substances List)

Typical usage ratio

• 0.5–3% on the weight of raw hides, with precise adjustment for climate and logistics time
• Evaluated through long-term stability and absence of putrefaction

Downstream process integration

• Added to soaking drums or vats before the main tanning sequence
• Can combine with short-term antiseptics or fungicides in pretreatment

Final product types

• Wet blue and crust leather for automotive, apparel, and upholstery
• Vegetable-tanned hides for consumer leather goods
• Finished leather for footwear and accessories

4. Cooling Water System Biocide in Power Generation

Power plants integrate THPS for biofouling control in recirculating cooling water towers and associated heat exchangers. Dosing mitigates algae, bacteria, and biofilm build-up, which can lower heat transfer efficiency and cause system blockages. Operators comply with water discharge limits and workplace chemical safety measures, performing periodic system audit to balance effectiveness with mechanical integrity.

• Monitored through real-time conductivity and biological activity testing

Final product types

• Electric power with uninterruptible plant performance
• Steam supply for industrial process heating
• Process water discharged within legal environmental limits

5. Textiles—Antimicrobial Treatment for Technical Finishes

Textile finishing houses use THPS in antimicrobial finishing compositions for performance apparel, protective wear, and technical fabrics. The treatment delivers durable resistance against bacterial growth, odor, and discoloration caused by sweat and environmental exposure. Analytical laboratories define dosing based on textile weight, end-use requirement, and washing durability protocols as per compliance with global textile safety standards.
