WT-S Standard Coal-Based Granular Activated Carbon

Key Features

1. Coal-Based Raw Material

WT-S is manufactured using bituminous coal as the primary raw material. Coal-based activated carbon is widely used in industrial water filtration and wastewater treatment because of its established production processes and broad range of granular applications.

2. Standard Iodine Adsorption Value Above 900 mg/g

WT-S has an iodine adsorption value above 900 mg/g, providing a measurable indicator of the adsorption characteristics of the activated carbon.This specification makes WT-S suitable for evaluation in standard-duty water filtration systems where general organic adsorption is required.

3. Mechanical Strength Above 90%

WT-S has a specified crush strength above 90%. Mechanical strength is an important consideration for granular activated carbon used in fixed-bed filtration systems, particularly where carbon handling and backwashing are part of normal operation.

4. Practical Standard-Grade Performance

WT-S combines defined adsorption and physical specifications in a standard coal-based GAC product. It is suitable for evaluating in water treatment projects requiring regular supply and large media volumes without necessarily specifying a higher iodine-value grade.

Applications

WT-S is designed for general municipal and industrial water treatment applications where granular activated carbon is used as an adsorption medium.

1. Municipal Water and Wastewater Treatment

Municipal treatment facilities use granular activated carbon to reduce residual organic contaminants and certain compounds affecting water quality.

WT-S can be evaluated for standard-duty filtration applications in municipal water and wastewater treatment systems, subject to the required treatment targets and applicable product approval requirements.

2. Industrial Wastewater Treatment

Industrial wastewater may contain dissolved organic compounds, color-causing substances and other contaminants from manufacturing and processing operations.

WT-S can be considered as granular adsorption media in suitable industrial wastewater treatment systems. Product selection should account for the wastewater composition, organic loading, suspended solids and required effluent quality.

3. Industrial Process Water Filtration

Industrial facilities may use activated carbon filtration as part of process water treatment to reduce selected organic contaminants before downstream processing.

WT-S provides a coal-based granular media option for evaluating in pressure-filter and gravity-filter systems, depending on the required water quality and equipment configuration.

4. General Water Filtration and Pretreatment

Granular activated carbon is commonly incorporated into water filtration systems to adsorb selected organic compounds and substances affecting color and odor.

WT-S can be considered for general industrial and non-potable water filtration applications where its specifications meet the treatment requirements. For drinking water applications, product-specific certifications and applicable regulatory requirements should be confirmed before selection.

Technical Advantages

Granular Structure for Fixed-Bed Filtration

WT-S is supplied as granular activated carbon rather than powdered or extruded carbon. Its granular form is suitable for fixed-bed filtration equipment, including commonly used pressure and gravity filter systems.

The actual filtration performance depends on particle size, bed depth, flow velocity and system configuration.

Defined Adsorption Properties

The iodine adsorption value above 900 mg/g and specific surface area above 900 m²/g provide measurable product specifications for comparing WT-S with other granular activated carbon grades.

Actual contaminant removal depends on the target compounds, water composition, contact conditions and operating parameters. Iodine value should not be treated as a direct measurement of removal efficiency for every water contaminant.

Mechanical Strength for Routine Operation

With crush strength above 90%, WT-S has a specified mechanical property relevant to granular carbon handling and filtration system operation.Particle attrition and fines generation should still be evaluated under the actual backwashing conditions and applicable test methods.

Suitable for Standard-Duty Water Treatment Projects

WT-S provides a standard-grade coal-based granular activated carbon option for general municipal and industrial water treatment applications.

For projects with higher adsorption requirements or particularly demanding effluent targets, a higher iodine-value activated carbon grade may also be evaluated.

Quality Assurance & Certifications

PURESTAR applies quality control procedures throughout activated carbon manufacturing, from raw material preparation and carbonization to activation and finished product inspection.

WT-S is supplied with defined technical specifications covering iodine adsorption value, moisture, ash, floating rate, crush strength and particle size distribution.

Quality Management Systems

PURESTAR's applicable management system certifications include:

• ISO 9001 – Quality Management System

• ISO 14001 – Environmental Management System

• ISO 45001 – Occupational Health and Safety Management System

These are company-level management system certifications, rather than product-specific drinking water approvals.

FAQ

What Is WT-S Coal-Based Granular Activated Carbon?

WT-S is a standard-grade granular activated carbon manufactured from bituminous coal through carbonization and steam activation. It is supplied as granular filter media for general municipal and industrial water treatment applications. Its iodine adsorption value is above 900 mg/g, with crush strength above 90%.

What Is the Difference Between WT-S and WT-P?

The main difference is their iodine adsorption value and corresponding product grade.

• WT-S: Standard grade with an iodine adsorption value above 900 mg/g.

• WT-P: Higher iodine-value grade with an iodine adsorption value above 1000 mg/g.

WT-S is intended for standard-duty water treatment applications, while WT-P can be evaluated for projects with higher organic loading or more demanding adsorption requirements.

The appropriate grade should be selected according to actual water quality, treatment targets and operating conditions.

Is WT-S Suitable for Drinking Water Treatment?

WT-S is primarily presented as a standard coal-based granular activated carbon for municipal and industrial water treatment.

This product page does not establish a specific drinking water certification for WT-S. For potable water applications, buyers should confirm the applicable product-specific certification and local drinking water contact requirements before purchase.

Can WT-S Be Used in Pressure and Gravity Filters?

WT-S is supplied in granular form and can be evaluated for both pressure-filter and gravity-filter systems.

The appropriate particle size and operating conditions depend on equipment design, water flow rate, bed depth, filtration requirements and backwashing arrangements.

How Often Should WT-S Be Backwashed?

There is no universal backwashing interval for all WT-S filtration systems.

Backwashing frequency should be determined according to pressure drop across the bed, suspended solids loading, effluent quality and the filter manufacturer's operating recommendations. Regular monitoring helps operators determine when backwashing is required without relying on a fixed time interval.

Can WT-S Be Thermally Regenerated?

The suitability of thermal reactivation depends on the adsorption history, contaminants captured, carbon condition and the available reactivation process.

Thermal regeneration should not be assumed to restore the original adsorption performance. Buyers should evaluate the carbon condition and consult the manufacturer or reactivation service provider before choosing a regeneration route.

Can PURESTAR Provide a TDS and COA for WT-S?

Yes. PURESTAR can provide the relevant technical data sheet, material safety data sheet and batch-specific certificate of analysis for product evaluation. Buyers can contact our team to confirm document availability and specific testing requirements.
