Thioscav Q6-125


Advanced Solutions for H₂S and Mercaptan Removal in Landfill and Organic Waste Gas Processing Innovative Gas Treatment for a Cleaner, Safer Environment

Clean Air Reliable Operations Regulatory Compliance WITH Thioscav Q6-125 and Thioscav Q6-125ECO

Biological Desulfurization

We offer dual properties scavenger Thioscav Q6-125ECO for sustainable, low-cost treatment of mixed sulfur compounds and sulfur reducing bacteria

  • Fully automated operation with minimal chemical consumption.
  • Ideal for composting facilities and organic waste digesters with continuous emissions.

Mercaptan Removal Solutions

For low-to-moderate mercaptan concentrations, we provide catalytic oxidation reagents:

  • Catalytic Oxidation Units that convert mercaptans into odorless, non-toxic compounds without significant methane loss.

Benefits:

  • Extremely low odor thresholds achieved (<0.002 ppm).
  • Regeneration options for reduced waste generation.

Non-Triazine H₂S Scavenger

We supply next-generation non-triazine chemical scavengers that rapidly and irreversibly bind hydrogen sulfide without producing solid by-products or secondary pollution.

Advantages:

  • No formation of insoluble residues, preventing clogging in gas handling systems.
  • Effective over a wide pH range and temperature conditions.
  • Compatible with biogas upgrading systems (PSA, membrane, water scrubbing).
  • Lower environmental footprint compared to conventional triazine products.

Applications:

  • Direct injection into landfill gas collection wells.
  • Inline dosing in gas conditioning units before energy recovery.

Biological H₂S and Mercaptan Scavenger Thioscav Q for Landfill Gas and Composting Applications

Product Overview

Our scavenger is a dual-action treatment solution combining fast chemical neutralization of hydrogen sulfide (H₂S) and mercaptans with biological control of sulfur-reducing bacteria (SRB). This unique formulation is designed for continuous use in landfill gas streams and composting facilities, where both chemical contaminants and microbial activity contribute to odor, corrosion, and operational issues.

Biological H₂S and Mercaptan Scavenger for Landfill Gas and Composting Applications WITH Thioscav Q

Mechanism of Action

Chemical Phase

  • Rapidly reacts with H₂S and mercaptans, converting them into stable, non-volatile, and non-corrosive sulfur compounds.
  • Maintains high removal efficiency even at fluctuating gas flow rates and contaminant concentrations.

Biological Phase

  • Contains specialized biocidal agents targeting Desulfovibrio, Desulfotomaculum, and other SRB species responsible for biological sulfide production.
  • Reduces microbial regeneration of H₂S in gas collection systems, compost piles, and leachate handling units.

Applications

  • Landfill Gas Treatment: Inline injection into gas extraction systems before compression or energy recovery units.


  • Composting Facilities: Spraying or dosing into aeration and exhaust systems to neutralize odor emissions.


  • Leachate and Condensate Management: Addition to liquid handling systems to suppress SRB activity and reduce H₂S off-gassing.

Performance

  • H₂S Removal Efficiency: >99% at inlet concentrations up to 5,000 ppm.


  • Mercaptan Reduction: Below odor threshold (<0.002 ppm methyl mercaptan).


  • SRB Suppression: >95% reduction in active SRB populations within 48 hours of application.

Key Benefits of

Thioscav Q6-125(Eco)

  • Dual Functionality: Simultaneous removal of chemical sulfur compounds and suppression of SRB activity.
  • Extended Protection: Longer intervals between treatments due to reduced biological reformation of H₂S.
  • Non-Triazine Formula: Avoids solid precipitation, preventing pipeline and equipment clogging.
  • Broad Application Range: Effective in gas, leachate water, and moist compost environments.
  • Environmental Safety: Biocidal components are biodegradable and compliant with environmental regulations.
  • Regulatory Compliance: Meets EU, US EPA, and GCC environmental emission standards.
  • Operational Reliability: Prevents corrosion, catalyst poisoning, and equipment downtime.
  • Community Acceptance: Eliminates nuisance odors, improving relations with surrounding communities.
  • Sustainability: Low waste generation, environmentally safe by-products, and reduced chemical footprint.
