Activated Carbon in Water Purification

Water purification is the process of removing contaminants, toxins, and impurities from water to make it suitable for various applications, including drinking, cooking, and industrial processes. Common contaminants found in water include organic compounds, chlorine, pesticides, heavy metals, and unpleasant odors and tastes.

Activated carbon, also known as activated charcoal, is a highly porous form of carbon with a large surface area and a complex network of pores. It is produced by heating carbon-rich materials, such as coconut shells, wood, or coal, at high temperatures without oxygen, resulting in a substance with remarkable adsorption properties.

Kalimati (NEERSORB™) Activated carbon serves as a versatile and effective adsorbent in various water treatment processes. It successfully adsorbs organic compounds, such as volatile organic compounds (VOCs), pesticides, and industrial chemicals, from water. These contaminants can give unpleasant tastes, odors, and colors to water, making it unpalatable and potentially harmful to health. Activated carbon traps these organic molecules within its porous structure, resulting in cleaner and better-tasting water.

Chlorine is commonly used as a disinfectant in water treatment to kill bacteria and pathogens. However, residual chlorine in treated water can cause an unpleasant taste and odor. Activated carbon removes chlorine and its byproducts, such as trihalomethanes (THMs) and chloramines, improving the overall quality and taste of drinking water.

Activated carbon can also adsorb heavy metals, including lead, mercury, arsenic, and cadmium, which may be present in water due to industrial pollution or natural sources. These metals pose serious health risks when consumed in elevated concentrations. By capturing heavy metal particles, activated carbon helps reduce their presence in drinking water, safeguarding public health.

While activated carbon primarily adsorbs organic compounds and chemicals, certain types of activated carbon, such as silver-impregnated carbon, also have antimicrobial properties. These carbon-based antimicrobial filters can help inhibit the growth of bacteria, viruses, and other pathogens in water, providing an additional layer of protection against waterborne diseases.

Activated carbon stands as a guardian in the realm of water purification, offering an effective and environmentally friendly solution for removing contaminants and impurities from water. Whether it's eliminating organic compounds, reducing chlorine levels, removing heavy metals, or inhibiting microbial growth, activated carbon plays a crucial role in ensuring clean, safe, and refreshing drinking water for communities around the world. As we raise a glass of crystal-clear water, let's appreciate the unsung heroes of activated carbon in purifying the essence of life and safeguarding our health and well-being.
