SRC-BL Impregnated Coal Columnar Carbon for Wastewater Odor Removal

Key Features

• Cost-effective sulfide-specific impregnation

  Balanced alkaline impregnation delivers dependable H₂S and acid gas removal at a lower total cost for large-volume ambient odor control installations.

• Uniform 4mm extruded particle shape

  Consistent cylindrical structure promotes even gas distribution across the filter bed, avoiding flow channeling and premature breakthrough.

• Durable coal base with high mechanical strength

  90% abrasion resistance minimizes particle breakage during handling and operation, reducing fine particle carryover to downstream equipment.

• Reliable base carbon adsorption capacity

  Base carbon provides >50% CTC value and >900 m²/g surface area to capture co-existing organic odor compounds.

Applications

• Light-Load Wastewater Ambient Odor: Pumping stations, grit chambers and general facility perimeter odor control generate low-concentration H₂S where premium-grade carbon is over-engineered. SRC-BL's balanced impregnation delivers dependable sulfide removal at an accessible cost for large-volume, low-intensity installations.

• Biogas & Landfill Gas Light-Duty Sweetening: Low-concentration biogas and landfill gas streams need basic H₂S control before utilization. SRC-BL provides cost-effective sulfide removal without the capacity premium of higher-grade desulfurization media.

• Laboratory General Exhaust Polishing: Basic fume hood exhaust treatment removes low-level sulfide and acid gas fumes before atmospheric discharge. SRC-BL offers adequate performance for these non-critical ventilation applications.

• General Industrial Low-Concentration Acid Gas: Manufacturing facilities with low-level acidic exhaust need routine, economical abatement. SRC-BL fills this requirement without the capital expense of premium impregnated grades.

Technical Advantages

• Offers a lower upfront cost alternative to premium impregnated desulfurization carbons for light-load odor control, reducing total project capital expenditure.

• Consistent bed packing density makes it easy to calculate filling volumes for standard filter vessels.

• Tested to national activated carbon quality standards with stable quality across production batches.

• Compatible with standard fixed-bed deodorization systems requiring no equipment modification for drop-in replacement.

FAQ

Q: When should I choose SRC-BL over SRC-A?

A: Choose SRC-BL for low-concentration ambient odor control, large fill volumes and budget-sensitive projects. Choose SRC-A for higher-concentration process exhaust where higher sulfur capacity and longer service life are required.

Q: Can SRC-BL be used for high-temperature flue gas?

A: SRC-BL is designed for ambient to moderate temperature odor and acid gas control. For high-temperature flue gas, we recommend TLX activated coke or powdered DIOSORB-S injection systems.

Q: Can SRC-BL be used for ammonia and alkaline odors?

A: SRC-BL is formulated specifically for acidic sulfide gases. For ammonia and alkaline amine odors, we recommend dedicated alkaline gas impregnated carbon grades such as PFH-K or ARC-A. For mixed odor streams containing both acidic and alkaline components, the two grades can be arranged in sequential bed layers.
