DecomClear® Hâ‚‚S Rapid Clear Z
A zinc chloride–based hydrogen sulfide scavenger specifically formulated for dredging operations and sludge handling where rapid Hâ‚‚S release occurs as material surfaces.
Product Overview
DecomClear® Hâ‚‚S Rapid Clear Z is a zinc chloride–based hydrogen sulfide scavenger specifically formulated for dredging operations and sludge handling where rapid Hâ‚‚S release occurs as material surfaces. It combines the proven strength of zinc chloride precipitation with fast-reacting amines and stabilisers to deliver immediate knockdown of Hâ‚‚S emissions and extended suppression during hopper storage.
Applications
-
Dredging and remediation of H2S generating sludges.
-
Hopper and bucket operations where sludge surfaces release Hâ‚‚S
-
Odor and hazard reduction during sludge transfer and dewatering
-
Industrial and municipal sludge handling where zinc-based scavenging is acceptable
Product Features
-
Rapid Knockdown: Dual-action zinc + amine system captures Hâ‚‚S instantly at surface break.
-
Extended Suppression: Sodium gluconate stabiliser reduces re-release of Hâ‚‚S during hopper residence.
-
Enhanced Wetting: Non-ionic surfactant ensures uniform coverage of sludge surfaces.
-
High Reactivity: Designed for spray-bar and atomising nozzle applications.
-
Proven Chemistry: Based on zinc chloride precipitation, a robust and reliable Hâ‚‚S control method.
Physical Properties
Appearance: Clear to slightly hazy liquid
Odour: Mild, slightly amine-like
Specific Gravity: ~1.45 – 1.50
pH (at 25°C): 3.0 – 4.0
Solubility: Fully water soluble
Recommended Application
-
Spray curtain above hopper entry to intercept sludge as buckets dump.
-
Continuous surface misting over hopper sludge to prevent secondary emissions.
-
Dosing rate: 1.5–2.0 L per m³ of sludge, adjusted per Hâ‚‚S monitor readings.
Typical Dosage Performance
-
Instant Hâ‚‚S reduction: >90% reduction within seconds of sludge contact.
-
Sustained suppression: Maintains low Hâ‚‚S levels in hopper for up to 4–6 hours, depending on sludge composition.
Storage and Handling
-
Store in HDPE, FRP, or lined mild steel tanks.
-
Avoid contact with unlined carbon steel or reactive metals.
-
PPE required: gloves, goggles, protective clothing.
-
Protect from frost and direct sunlight.
Safety
-
Corrosive liquid — zinc chloride is hazardous.
-
Ensure ventilation when spraying in confined areas.
-
Refer to SDS for detailed handling and first aid guidance.
