CTO Filter Compressed Activated Carbon Filter Cartridges 10/20/30 Inch Length

Material and Structure

• Material: It mainly uses high-quality coconut shell activated carbon as the raw material. Coconut shell activated carbon has the characteristics of well-developed pores, a large specific surface area, and strong adsorption capacity, which can effectively remove various impurities in water. In addition, food-grade binders are usually used in the filter element to compress the activated carbon powder into a filter element with certain strength and shape, while ensuring that it will not cause secondary pollution to the water quality.
• Structure: It is generally cylindrical with a length of about 10 inches (approximately 25.4 centimeters). The activated carbon particles inside the filter element are compressed to form a compact structure, which not only ensures a large adsorption area but also effectively blocks the passage of impurity particles, achieving a good filtration effect.

Working Principle

• Adsorption Function: Coconut shell activated carbon has a highly developed microporous structure and a huge specific surface area. Through physical adsorption, it can adsorb substances such as organic matters, residual chlorine, peculiar smells, and pigments in water onto its surface and pores. For example, residual chlorine will undergo a chemical reaction with the active sites on the surface of the activated carbon, be adsorbed and removed, thus eliminating the chlorine smell in the water and improving the taste of the water.
• Filtration Function: The structure of the compressed activated carbon filter element can play a role in mechanical filtration for suspended particles, colloids, and other impurities in water. When these impurities pass through the filter element, they will be intercepted by the gaps and pores between the activated carbon particles, further purifying the water and reducing the turbidity of the water.

Characteristics

• High-efficiency Adsorption: It has a strong adsorption capacity for residual chlorine, organic matters, etc. in water, which can significantly improve the taste and smell of the water, making the filtered water clearer and sweeter.
• Good Filtration Performance: It can effectively remove tiny particle impurities in water, such as sand, rust, etc. The filtration accuracy usually reaches about 5 microns, providing higher-quality influent water for subsequent water treatment processes.
• Safe and Environmentally Friendly: Using coconut shell activated carbon as the raw material, it is a natural and environmentally friendly material. The use of food-grade binders ensures that the filter element will not release harmful substances during the filtration process, safeguarding the safety of drinking water.
• Longer Service Life: Under normal usage conditions, the service life of a 10-inch compressed coconut shell activated carbon filter element is generally 3 to 6 months. The specific service life depends on factors such as the quality of the raw water and the frequency of use.

Application Fields

• Household Water Purifiers: It is a common pre-filtration filter element in household reverse osmosis water purifiers, ultrafiltration water purifiers, etc. It is used to remove residual chlorine and impurities in tap water, protect the subsequent filter elements and reverse osmosis membranes, and improve the overall performance and effluent water quality of the water purifier.
• Commercial Water Treatment: In some small-scale commercial water usage scenarios, such as the direct drinking water equipment in restaurants, cafes, offices, etc., the 10-inch compressed coconut shell activated carbon filter element is also widely used to provide people with safe and high-quality drinking water.
• Industrial Pretreatment: In some industrial water pretreatment processes where the water quality requirements are not particularly high, such as in certain industrial cooling circulation water systems, the pretreatment of boiler make-up water, etc., the coconut shell activated carbon filter element can be used to initially remove organic matters and residual chlorine in the water, reducing the burden on subsequent treatment equipment.
