Success Stories

Case Studies

Real-world projects demonstrating activated carbon performance across industries.

Water Treatment

Municipal Water Treatment Plant — Southeast Asia

Client: Municipal water authority serving 500,000+ residents

Challenge

Aging sand filtration system unable to meet new drinking water standards for chlorine residuals, taste/odor compounds, and emerging PFAS contaminants.

Solution

Retrofitted 12 filtration beds with coconut shell GAC (12×40 mesh, iodine ≥1050 mg/g). Designed dual-bed configuration with 15-minute EBCT per stage.

Product Used

Coconut Shell GAC 12×40

Results

99.8%

Chlorine removal efficiency

<4 ppt

PFAS reduced from 85 ppt (below EPA MCL)

2 weeks

Taste & odor complaints eliminated

18 months

GAC bed life before first replacement

35%

Annual cost savings vs. chemical dosing

Gold Mining

Gold Mining Operation — West Africa

Client: Large-scale gold mine processing 8,000 tonnes ore/day

Challenge

Existing carbon supplier delivering inconsistent quality causing 12% gold loss in CIL circuit. Carbon attrition rate exceeding 40 g/tonne processed, increasing operating costs.

Solution

Supplied premium GRC Series coconut shell carbon (6×12 mesh, hardness ≥98%, iodine ≥1050). Implemented quality-assured supply chain with pre-shipment testing and COA for every batch.

Product Used

Gold Recovery Carbon GRC Series

Results

96.5%

Gold recovery rate (up from 88%)

55%

Carbon attrition reduction (40 to 18 g/t)

22 kg

Au/tonne carbon loading capacity

80+

Reactivation cycles (up from 40)

$1.2M

Annual savings from reduced consumption

Air Purification

Industrial Air Purification — Chemical Manufacturing Plant

Client: Chemical manufacturing facility with VOC emission compliance requirements

Challenge

Plant facing regulatory penalties for exceeding VOC emission limits (toluene, xylene, MEK). Existing carbon beds breaking through after only 3 months, causing frequent unplanned shutdowns.

Solution

Replaced generic GAC with engineered pellet activated carbon (4mm, CTC ≥65%) optimized for gas-phase adsorption. Redesigned bed configuration with lead-lag arrangement and online monitoring.

Product Used

Pellet Activated Carbon 4mm

Results

99.2%

VOC removal (180 mg/m³ to 1.5 mg/m³)

14 months

Carbon bed life (up from 3 months)

Zero

Regulatory violations since installation

40%

Pressure drop reduction vs. previous media

8 months

ROI achieved from avoided penalties

Food & Beverage

Food & Beverage Processing — Sugar Refinery

Client: Major sugar refinery processing 2,000 tonnes raw sugar/day

Challenge

Inconsistent decolorization results affecting refined sugar quality grades. Existing PAC supplier unable to meet HALAL certification requirements for export markets.

Solution

Supplied wood-based PAC (methylene blue ≥200 mg/g) with full HALAL, KOSHER, and FDA certifications. Optimized dosing protocol through laboratory trials with client’s specific sugar solutions.

Product Used

Wood Based PAC Food Grade

Results

45%

Color reduction improvement (ICUMSA 800→45)

20%

PAC dosage reduced via optimized contact

100%

HALAL compliance for Middle East exports

Zero

Quality rejections in 12 months

15%

Annual PAC cost savings (lower dosage)

Biogas / Air Purification

Biogas H₂S Removal — UAE Plant (78-Ton Shipment)

Client: Biogas facility in the United Arab Emirates

Challenge

Raw biogas carried a corrosive H₂S load threatening engines and downstream piping. The buyer had been quoted KOH-impregnated carbon by default, adding chemical cost plus storage and disposal complications the site did not want to take on.

Solution

Matched the grade to the actual gas instead of the habit: 78 tons of non-impregnated 4mm coal-based columnar carbon at CTC 60, run in a lead-lag arrangement. Shipped in sealed jumbo bags (FIBC) on pallets and delivered CIF Jebel Ali with batch COA and pre-shipment lab testing on CTC, particle size, moisture, hardness and ash.

Product Used
