Water purifier filter knowledge - activated carbon filter

In modern life, water purifiers have become an indispensable household appliance for many families. They can effectively filter impurities and harmful substances in water to ensure the safety and health of the water we drink. In the water purifier, the filter element is the core component, and its performance and quality directly affect the water purification effect. Today, let's take a deep look at a common water purifier filter element - activated carbon filter element.

1. Definition and principle of activated carbon filter element
Activated carbon filter element, as the name suggests, is a filter element with activated carbon as the main filter material. Activated carbon is a multi-pore carbonized product with extremely rich pore structure, which gives it good adsorption characteristics. The activated carbon filter element uses the adsorption capacity of activated carbon to effectively remove harmful substances such as organic matter, residual chlorine, odor, pigments, etc. in the water, making the water quality purer.

The filtration principle of the activated carbon filter element is mainly based on the adsorption of activated carbon. When water flows through the activated carbon filter element, the harmful substances in the water will be adsorbed by the micropores on the surface of the activated carbon, thereby achieving the purpose of purifying the water quality. At the same time, the activated carbon filter element can also intercept solid particles and microorganisms such as bacteria in the water through its internal filter layer.

2. Types and characteristics of activated carbon filter elements
Activated carbon filter elements can be divided into many types according to their production process and use, such as compressed activated carbon filter elements, bulk activated carbon filter elements, etc. Different types of activated carbon filter elements also differ in filtering effect and service life.

Compressed activated carbon filter element: It uses coal-based activated carbon and coconut shell activated carbon with high adsorption value as filter materials, and is sintered and compressed by food-grade adhesive. This filter element is wrapped with a layer of non-woven fabric with filtering function inside and outside to ensure that the carbon core itself will not drop carbon powder. At the same time, soft nitrile rubber sealing pads are installed at both ends of the carbon core, which has good sealing performance.
Bulk activated carbon filter element: The activated carbon particles are loaded into a special plastic shell, and the end caps are welded to the two end faces of the shell with welding equipment. Non-woven filter sheets with filtering function are placed at both ends of the shell to ensure that the carbon core will not drop carbon powder and black water when in use. This filter element can be made into different types of connectors according to customer needs, and the interface methods include flat pressure type and pipeline type.
The main features of the activated carbon filter element are strong adsorption capacity, good filtration effect and long service life. At the same time, the activated carbon filter element also has the advantages of low cost and easy replacement, which makes it widely used in water purifiers.

3. Maintenance and replacement of activated carbon filter element
Although the activated carbon filter element has many advantages, we still need to pay attention to its maintenance and replacement during use. Regular replacement of activated carbon filter element is the key to ensuring the water purification effect. Generally speaking, the service life of activated carbon filter element is generally 6-8 months, and the specific replacement cycle needs to be determined according to the water quality and water consumption.

When replacing the activated carbon filter element, we need to pay attention to the following points:

Close the water inlet valve of the water purifier to ensure that the water source has been cut off.
Remove the old activated carbon filter element, and be careful to avoid the scattered activated carbon particles in the filter element.
Clean the installation position of the filter element to ensure that there are no impurities left.
Install a new activated carbon filter element to ensure that the filter element is tightly connected to the water purifier.
Open the water inlet valve and check whether the filter element is installed correctly and whether there is any water leakage.
In addition, we also need to clean and dry the activated carbon filter element regularly to extend its service life and maintain the water purification effect. However, it should be noted that cleaning and drying should be carried out under the guidance of professionals to avoid damage to the filter element due to improper operation.

4. Application fields of activated carbon filter elements
Activated carbon filter elements are favored for their good filtering effect and wide application fields. It can be used not only in household water purifiers, but also in commercial water purifiers, industrial water treatment equipment, etc. In the food, beverage, pharmaceutical and other industries, activated carbon filter elements are also widely used for water purification in the production process.

In household applications, activated carbon filter elements can effectively remove harmful substances such as residual chlorine and odor in water, and improve the taste and quality of drinking water. In commercial and industrial applications, activated carbon filter elements can ensure the safety and stability of production water, improve product quality and production efficiency.
