Access to safe drinking water remains a global challenge. Waterborne diseases have historically led to devastating pandemics, and in many parts of the world, clean water is still a scarce resource. To combat this, effective water treatment systems have become essential.
Among these, activated carbon stands out for its simplicity, efficiency, and sustainability. Derived from carbonaceous materials like coconut shells, macadamia nut shells, and other organic materials, activated carbon offers a reliable solution for water purification while supporting environmentally conscious practices.
Understanding Activated Carbon
Activated carbon is a highly porous material with an exceptional surface area, making it an effective tool for filtering and purifying liquids and gases. Its structure allows water and other substances to flow through it while trapping contaminants on its surface. Produced by heating carbonaceous or organic materials, the activation process enhances its adsorption properties, enabling it to capture a wide range of pollutants. Activated carbon comes in two primary forms: powdered activated carbon (PAC), which is finer and suited for intermittent or specialised applications, and granular activated carbon (GAC), commonly used in continuous water filtration systems due to its larger particle size.
Applications in Drinking Water Treatment
Activated carbon is one of the most effective filtration materials for drinking water treatment. The effectiveness lies in its ability to adsorb impurities. Its porous surface and high surface area attract and hold contaminants such as organic compounds, certain inorganic substances, and microbes. The adsorption process ensures the removal of harmful impurities while improving water’s taste and odour.
Activated carbon plays a crucial role in various water treatment applications, including:
Municipal Water Treatment: Large-scale purification for urban water supplies.
Home Filtration Systems: Point-of-use filters for households.
Portable Purifiers: Compact solutions for emergencies or outdoor activities.
Advantages of Using Activated Carbon
Activated carbon filters offer several key benefits:
Versatility: Remove a broad range of contaminants, including organic compounds and odour-causing impurities.
Taste and Odour Improvement: Unpleasant smells and tastes are effectively neutralised.
Safety: Safe to touch, widely used and trusted in Australia and globally for its reliability.
Simplicity and Robustness: Targets contaminants at high/low concentrations when encountered in the raw water supply until the filter is consumed and replaced.
PFAS Removal: Prolonged exposure to PFAS-contaminated water can lead to various health risks. Granular activated carbon (GAC) filters are highly efficient at removing PFAS from water sources, providing safer, cleaner drinking water and minimising long-term environmental contamination.
Effective Air Purifier: Activated carbon is an effective filtering agent for gases and liquids. This makes activated carbon air purifiers very popular in urban areas with poor air quality. These filters provide clean air in closed surroundings, promoting health and reducing the risks of inhaling polluted air.
Challenges and Considerations
While highly effective, activated carbon water filters do come with considerations:
Maintenance and Replacement: Filter changes are required periodically to maintain efficiency. Fortunately, this process is cost-effective due to the simplicity of activated carbon products.
Limitations: While activated carbon excels at removing many contaminants, certain heavy metals and viruses require supplementary filtration and/or disinfection solutions.
