DecomClear® H₂S Rapid Clear
A fully biodegradable hydrogen sulfide scavenger formulated for use in refinery wastewater treatment and sludge handling applications.
Product Overview
DecomClear® H₂S Rapid Clear is a fully biodegradable hydrogen sulfide scavenger formulated for use in refinery wastewater treatment and sludge handling applications. Unlike zinc-based products, it uses an advanced glyoxal-amine system combined with biodegradable stabilisers to achieve rapid H₂S knockdown while remaining compliant with environmental and wastewater treatment requirements.
Typical Applications
-
Refinery wastewater treatment where zinc addition is restricted
-
Municipal and industrial sludge handling
-
Odor and hazard suppression during dredging or sludge transfer
-
Situations requiring readily biodegradable chemistry (OECD 301 compliant)
Physical Properties
Appearance: Clear to light yellow liquid
Odour: Mild, slightly sweet (glyoxal-like)
Specific Gravity: ~1.05 – 1.10
pH (at 25°C): 6.0 – 7.0
Solubility: Fully water soluble
Recommended Application
-
Spray curtain at sludge transfer points to intercept H₂S release.
-
Continuous misting over hopper or sludge surface for suppression.
-
Dosing rate: 1.0–1.5 L per m³ of sludge, adjustable based on H₂S monitoring.
Typical Dosage Performance
-
Instant H₂S reduction: >85–90% reduction within seconds of sludge contact.
-
Sustained suppression: Maintains low H₂S levels for up to 4 hours.
Storage and Handling
-
Store in HDPE or FRP tanks.
-
Protect from extreme heat and frost.
-
Ensure adequate ventilation when spraying in enclosed areas.
Safety
-
Avoid contact with skin and eyes.
