Granular activated carbon filters
Magnor's Granular Activated Carbon (GAC) filters are custom-designed to meet the specific needs of drinking water or industrial process water treatment. They use a filter media composed of granular activated carbon, known for its high adsorption of organic contaminants, chlorine, sulfides and many undesirable compounds.
Depending on the application, some systems may use Centaur ® catalytic activated carbon, which is particularly effective for the removal of sulfides and chloramines through a continuously regenerated oxidation mechanism.
These filters come with all the necessary auxiliary equipment: control panels, automatic valves, internal distribution systems, and can be pre-assembled at the factory for simplified installation.
How does the granular activated carbon filter work?
A granular activated carbon filter works by physical and chemical adsorption. Activated carbon is a highly porous material that traps contaminants at the solid-liquid interface as water passes through the filter bed.
The flow rate and capacity of Activated Carbon Filters (GACs)
At Magnor, the design of carbon filters is adapted to your flow needs, ranging from 3 US gpm for small models to >250 US gpm per tank for large industrial or municipal facilities. Multiple units can be added in parallel to achieve higher total throughputs.
Types of activated carbon filters
Fiberglass Granular Activated Carbon Filter (FRP)
Fibreglass filters are lightweight and corrosion-resistant. They are suitable for small and medium-sized installations.
- Typical diameters: 7" to 36"
- Height: up to 72"
- Maximum pressure: 100 psi
- Charcoal volume: 0.5 cu. ft. to 22 cu. ft. depending on the model.
Steel Granular Activated Carbon Filter
Steel filters are robust and designed for large municipal and industrial applications.
- Diameters: up to 144"
- Height: 72"
- Pressure: Typically, 100 psi, but can be increased as required These filters can be equipped with pneumatic or electric butterfly valves and programmable logic controllers for washing cycle control.
Mounting and integration of granular activated carbon filters
Regardless of the type chosen, the filters can be delivered pre-assembled on a steel base or not, including piping, valves and control panel. This arrangement facilitates installation and reduces on-site costs.
Why use a carbon filter?
These filters are used to remove:
- Chlorine and chlorinated by-products
- PFAS
- La chloramine
- Certain organic compounds
- Hydrogen sulfide
- Colour
- Certain hydrocarbons
Applications of Granular Activated Carbon Filters
Drinking Water
Carbon filters are widely used in municipalities, mining camps, and communities to meet taste, odor, and public health standards. They are often integrated into processing chains including multimedia filters, UV systems and ion exchangers.
Process Water
In industry, these filters are used to protect sensitive processes against organic contaminants and chlorine, or to improve water quality, for example in pharmaceutical production or in the food industry.
