WT-S Coal Granular Activated Carbon for Sewage Pretreatment and Wastewater Purification

Key Features

Reliable Coal GAC for Wastewater Treatment

WT-S is a cost-effective, high-performance coal granular activated carbon for reliable sewage and wastewater treatment. It is a versatile solution for primary contaminant removal, biological treatment support and final polishing in multi-stage wastewater systems.

Engineered for Wastewater Performance

Produced by high-temperature steam activation at 850–950°C, WT-S features a 900–1100 m²/g  microporous structure for excellent dissolved organic adsorption. Strict quality control keeps ash content ≤15% to avoid excess sludge and disruptions to downstream processes.

Applications

• Municipal Sewage Treatment: Purifies municipal sewage to meet strict discharge standards.

• Industrial Wastewater Treatment: Removes harmful pollutants and improves water for industrial reuse.

• Post-Biochemical Treatment: Further eliminates residual impurities for higher effluent quality.

• Reclaimed Water Treatment: Ensures safe reuse of reclaimed water in agriculture, industry and municipal scenarios.

• Sewage Pretreatment: Effectively removes bulk contaminants in early-stage sewage treatment.

Technical Advantages

• High-temperature steam activation forms 900–1100 m²/g microporous structure for strong organic & COD adsorption

• Iodine number ≥900 mg/g, methylene blue ≥150 mg/g for balanced high-efficiency purification

• Hardness ≥90% minimizes breakage and dust in continuous operation

• Moisture ≤5%, ash ≤15% reduces sludge and protects downstream processes

• Versatile for municipal/industrial wastewater, pretreatment & post-biochemical polishing

• Stable performance lowers replacement frequency and operating costs

FAQ

Q1: What is WT-S activated carbon used for in sewage treatment?

A: WT-S activated carbon is used for primary organic adsorption, tertiary COD/color polishing, membrane fouling protection and odor control in municipal and industrial sewage treatment.

Q2: How does WT-S compare to other activated carbons for wastewater?

A: WT-S has higher adsorption capacity (iodine ≥900 mg/g), better mechanical strength and lower cost, making it the most cost-effective choice for general wastewater treatment.

Q3: Can WT-S be customized for sewage treatment?

A: Yes, WT-S supports custom particle sizes, low-ash acid-washed grades, thermal reactivation and bulk delivery for personalized wastewater treatment solutions.

Q4: What is your minimum order quantity (MOQ)?

A: MOQ depends on product type. Please contact us for detailed information.

Q5: Is spent WT-S activated carbon regenerable?

A: Yes, spent WT-S can be thermally regenerated at 850–900°C for 3–5 cycles (restoring 85–95% capacity), and can also be safely disposed or used as fuel.
