Activated carbon is a porous adsorbent made of carbonaceous materials. It has high adsorption performance and is widely used in water treatment, air purification and other fields. So, how does activated carbon filter water?
1. Adsorption principle of activated carbon
The adsorption principle of activated carbon mainly relies on its porous structure and huge surface area. There are a large number of micropores inside activated carbon. The size and distribution of these micropores are very suitable and can adsorb various molecules and ions. The larger the surface area of activated carbon, the stronger its adsorption capacity. When water passes through activated carbon, harmful substances and odor molecules in it are adsorbed on the surface of activated carbon, thereby purifying water quality.
2. Process of activated carbon water filtration
Before activated carbon can filter water, the water needs to be pre-treated. The purpose of pretreatment is to remove large impurities and suspended solids from the water to avoid clogging the activated carbon filter. Pretreatment usually includes steps such as sedimentation, filtration, and flocculation.
The pretreated water enters the activated carbon filter and is filtered through the pores of the activated carbon. During this process, harmful substances and odor molecules in the water are adsorbed on the surface of the activated carbon, while clean water flows out through the activated carbon.
Activated carbon filters need to be cleaned regularly to remove impurities and pollutants adsorbed on the surface of the activated carbon. The frequency of cleaning depends on the water quality used and the load of the filter. It is generally recommended to clean once a month.
3. The effect of activated carbon filtering water
Activated carbon filtered water can remove a variety of harmful substances and odors in the water, including heavy metals, organic matter, ammonia nitrogen, color, etc. The water treated by the activated carbon filter can meet the national drinking water standards and is harmless to human health.
4. Advantages of activated carbon filter
High efficiency: Activated carbon filter can remove various harmful substances and odors in water, and the purification effect is remarkable.
Safety: Activated carbon filters use physical purification methods without adding any chemicals and are harmless to the human body.
Environmental protection: Activated carbon filters use renewable resources, are reusable and are environmentally friendly.
Easy to operate: Activated carbon filters are very simple to install and use, and easy to maintain.
In general, Activated carbon water filtration is an efficient water purification method that can remove a variety of harmful substances and odors in the water and improve water quality. When using activated carbon filters, you need to pay attention to regular cleaning and maintenance to ensure their normal operation and service life. As people's requirements for water quality continue to increase, activated carbon filters will play a more important role in the future water purification field.
