Process of Deactivation and Reactivation
What is the primary treatment for Organics, Pesticides, and Herbicides?
Activated carbon serves as a standard treatment for these materials. It effectively removes volatile organic chemicals, thereby aiding in water filtration.
What process does spent activated carbon undergo?
If necessary, the spent activated carbon is first dried. It then experiences devolatilization/carbonization at temperatures ranging between 650º to 1,000º F.
Can activated carbon be recycled for reuse?
Absolutely! Reactivation enables the regeneration of spent granular or pelletized activated carbons, preparing them for another cycle of usage.
What is the typical temperature during the heating phase of reactivation?
In the reactivation phase, the exhausted activated carbon is heated to approximately 900°C. This happens in a non-oxidizing atmosphere in presence of steam.

Step-by-Step Guide to Charcoal Reactivation
Charcoal reactivation is a process largely governed by thermal treatment. Under high temperatures, usually between 600°C and 900°C, and the absence of oxygen, the activated carbon is rejuvenated.
Thermal vs. Steam vs. Acidic Reactivation
A common way of carrying this out is through the use of furnaces similar to those employed for coal activation. These include rotary kilns and multi-stage direct heating kilns. The process generally occurs between 500°C and 800°C.
The reactivation can also be performed using steam or acidic solution. In steam reactivation, steam is circulated through the coal bed to release trapped organic molecules. This method is particularly useful when striving to recover solvents contained in air streams.
Acidic reactivation, on the other hand, helps eliminate inorganic salts from the activated carbon that are not removed during thermal reactivation. A strong acid such as hydrochloric acid is typically used in this process.
The General Practice
In most practices, the activated carbon is exposed to high temperatures that volatilize the adsorbed components. Drying precedes this step, followed by heating to around 1000°F (538°C). Consequently, 75-90% of adsorbed materials are volatilized.
To remove residual volatiles and complete the carbon’s reactivation, steam is introduced into the system.
Do-It-Yourself Methods
Home methods are also viable options for small-scale needs. A popular DIY technique involves heating spent carbon in a steel pipe over a charcoal fire. Once hot, steam can be sent through it to volatilize the adsorbed compounds.
Another technique involves heating the spent carbon in an oven to a couple of hundred degrees Celsius or using a steam cleaner to blow steam.

Recharging Activated Charcoal Filters
The process of re-energizing activated charcoal filters is known as reactivation. Reactivation is an eco-friendly and cost-effective circular model, embraced for its sustainability.
Charcoal filters that have been used for purification or decolourisation can typically be recycled through thermal reactivation. This process involves the application of high-temperature furnaces that thermally destroy the organics adsorbed by carbon.
Reactivation facilities specialize in recycling a range of spent carbons, catering to different types of applications. These applications include clean water filtration, food-grade carbons, industrial chemical remediation, and air treatment services.
The philosophy behind this process prioritizes recycling over replacement, optimizing the resource’s lifecycle and minimizing waste production. Coupled with high-quality activated carbons, users gain from a holistic purification solution.
The spent carbon is treated at high temperatures in a reactivation furnace. Manufacturers ensure that these facilities conform to stringent air quality regulations and hold accreditations for Food Safety Management, making this an environmentally friendly solution.
Activated carbon technology strikes a balance between minimizing waste and reducing CO2 emissions while limiting the use of the world’s resources. This shows that activated carbons can be recycled for future use.
Certain companies have developed significant expertise in designing and operating conditions for effective reactivation of more challenging spent activated carbons. They utilize custom-designed carbon reactivation furnaces based on decades-long practice.
Reactivating charcoal filters has allowed improvements in process-sustainability related to energy and water consumption. Such advancements enhance the quality and effectiveness of the reactivation service, delivering value to customers.
Sustainable charcoal filter services are not just an environmental bonus but also aid in reducing CO2 footprint. Recycling activated carbon can significantly benefit a customer’s environmental impact while also reducing the carbon footprint of the service provider.
Maintaining and Extending Filter Lifespan
The regular cleaning of filter housing and components significantly aids in increasing their lifespan. Employing a mild detergent and warm water would suffice for this task. Proper rinsing with clean water is crucial to prevent residual contamination.
- Consistency in filter replacement: Abiding by the manufacturer’s replacement guidelines fosters effective running of the system. Such guidelines may refer to usage duration or filtered gallons.
- Inspection and specific cleaning tasks: The optimal functioning of certain filters demands specific cleaning techniques and routines. Implementing recommended strategies for each filter type guarantees longer service life.
- Avoiding demanding filtration scenarios: It’s recommended to let muddy water settle before running it through the filter. This way, unnecessary pressure on the system is avoided, thereby promoting longevity.
- Proactive system maintenance: Regular examination of the entire water filtration system maintains its integrity. Prompt attention to wear signs or contamination prevents negative impacts on water quality.
Inevitably, like any homely appliance, a time will come when the whole water filtration system needs a substitute to preserve potable water quality. However, routine upkeep can prolong this inevitability.
A crucial aspect of ensuring prolonged health of a filtration system hinges on user education. Encouraging regular cleaning tasks, prompt cartridge replacements and proper monitoring practices fortifies effective water treatment.
It’s also important to precisely follow manufacturer’s stipulated maintenance procedures for individual filtration systems. Incorrect approaches could lead to damage or inefficient functioning. A fine example detailing these pointers can be found here.
Troubleshooting Common Problems
The potency of activated carbon in trapping contaminants can give rise to a troubling ‘rotten egg’ smell due to the growth of biofilm on its surface. This issue is often caused by biological filters becoming overgrown.
- Water Odor: This type of odor can also arise due to chloramine levels leading to further growth on the filters.
- Troubleshooting: Enhanced pre-treatment methods to reduce filter load and modify flow rates can prevent overwhelming overload in activated carbon filters.
Activated carbon filters perform at an optimal level when regularly cleaned and maintained. Failure to uphold this essential practice can result in decreased efficiency, further odor problems, and other forms of performance degradation.
- Maintenance: Systematic change of these filters is crucial as they have a limited adsorption capacity; stale filters begin to release pollutants over time.
- Preventing Odors: Activated carbon’s primary role includes removing volatile organic compounds (VOCs) and odors, but it requires frequent monitoring and replacement to maintain this level of effectiveness.
One effective method to avoid common issues involves pre-loading the filter with water before the substance filtration process begins. This practice aids in ensuring an adequate flow and eliminates any chances of airlocks or blockages inside the filter setup.
- Filter Selection: Careful evaluation of activated carbon grade used for each requirement is another pivotal point; For instance, aquarium-grade carbon might not be suitable for home brewing.
If odor problems or reduced flow are detected with the use of activated carbon filters, a comprehensive system inspection and cleaning may be required. The objective is to guarantee the overall integrity of the system including its fittings and other components.
Reviving Charcoal Filters
In conclusion, reactivating and recharging charcoal filters involves a straightforward process. First, clean the filter thoroughly to remove particles. Next, bake it in an oven at 100 degrees Celsius for 15 minutes to reactivate the charcoal. Finally, cool it down naturally and reinstall it. This method helps to extend the filter’s lifespan and ensures optimal performance.
