Strong adsorbents like activated carbon are widely employed in water purification procedures, to filter out pollutants and undesired substances. Although, activated carbon for water treatment has many applications, it is a crucial tool used in industrial and municipal water treatment systems to purify wastewater, drinking water, and municipal water for use in processes.
What is activated carbon?
Due to its distinctive porous structure, substantial surface area, and attraction forces, activated carbon may draw and hold a variety of things to its surface.
There are many different types and variations of activated carbon water treatment. The extremely permeable surface structure is produced by heating a carbonaceous material, most frequently wood, coal, or coconut husks, in a rotating kiln. This "activates" the carbon and creates the material's carbon content.
Types of activated carbon
There are many different kinds of activated carbon, and each one has distinct material characteristics that make it ideal for a given use. As a result, producers provide a wide range of products that contain carbon dioxide for water treatment.
Depending on the application, activated carbon can be used in liquid, extruded, powdered, or granular form. It can either be used on its own or in combination with other techniques, such as UV disinfection.
The most popular kind of activated carbon is granular activated carbon (GAC), which is made from bituminous coal and is frequently used in water treatment systems.
Why is activated carbon an important part of the water treatment?
Although, it may not be immediately obvious, activated carbon frequently gives us access to clean water that is used for drinking, bathing, and other activities.
1: Activated carbon for drinking water applications
In order to ensure that the water is safe to drink and has a pleasant flavour and smell, drinking water treatment facilities use this for water treatment.
Purification of drinking water focuses on:
· Contaminant elimination
Activated carbon can be used to filter out harmful compounds such as endocrine disruptors, pesticides, and medications from water that is meant for consumption.
· Smell and Taste Control
Additionally, chemicals that cause unpleasant tastes and odours are reduced using activated carbon for water treatment.
· Cleansing by-products
Recently, activated carbon has also been utilized in drinking water treatment facilities, to lessen disinfection by-products, or DBPs.
Natural organic matter (NOM), which is present in water, and the disinfectants used to clean it combine to form DBPs. Utilizing activated carbon for Water Treatment, it has been possible to successfully eliminate the precursor (NOM) of disinfection by-products.
2: Activated carbon for Wastewater Treatment
Activated carbon is used in municipal and industrial wastewater treatment facilities. Municipal wastewater or the effluent from an industrial process may contain numerous components, which need to be separated before being disposed of in rivers or reused.
Under these circumstances, activated carbon water treatment helps protect rivers from pollutants like pesticides, gasoline, and other solvents. Again, by trapping the desired components, activated carbon removes them, allowing the water to be used for its original purpose or discarded.
· Process Water
Many industrial infrastructures have their own on-site operations to purify incoming municipal water, for use in their particular industrial process, in addition to specialised water treatment facilities.
To avoid equipment damage or the production of inferior goods, process water used in the production of beverages, pharmaceuticals, and similar products frequently needs to adhere to very strict criteria.
Process water applications typically use activated carbon to ensure that the water quality, meets the requirements of the intended usage.
For all of these uses of water treatment, activated carbon can be applied in a variety of ways. In every circumstance, including UV disinfection and particulate filtration systems, activated carbon can be used alone or in combination with a variety of treatment methods.
3: Other Applications of activated carbon in Water Treatment
It's crucial to keep in mind that activated carbon can be utilized in point-of-use and small-scale applications, such as those that are discussed below, in addition to its vital function in large water treatment facilities.
· Pond/Aquarium Filtration
Activated carbon for water treatment keeps aquatic ecosystems free of contaminants, which could harm inhabitants.
· Home-Based Filters
Activated carbon is also used by a number of in-home water filters, such as tap-mounted filters and refrigerator-mounted filters, to clean water.
Benefits of activated carbon in water treatment plants
Activated carbon filtering systems have many benefits when utilized in drinking and process water treatment systems.
1. Absorbs numerous components readily
Both organic and inorganic materials are on the list of elements and chemicals, which the activated carbon may simply eliminate.
2. Compact in size
The activated carbon filter system only requires a tiny or moderate amount of space. It can be employed in small or restricted space facilities as a result.
3. Simple Integration
It can be easily and swiftly implemented into the existing facilities.
4. Being economical
In larger facilities or production facilities, a replaceable activated carbon filter might be used. By removing the absorbed materials, the activated carbon filter can rebuild itself. This makes it significantly less expensive to purchase, and include new carbon filters on a regular basis.
Water is the most valuable resource in the world. As the population of the world grows, it will be more and more important to manage the water supplies effectively. An effective method for guaranteeing the safety of drinking water, protecting streams from potentially harmful effluent discharge, or assisting in the manufacture of high-quality items, is therefore the activated carbon water treatment.
