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)
