The use of powdered activated carbon mainly in two forms mainly: 1. activated carbon fiber cloth, 2. activated carbon particles
The main function of the activated carbon filter layer is to absorb organic gas, odor and toxic dust,
It is not only used to filter dust, but also to filter fine dust. It is mainly made of superfine fiber and static filter cloth
That is what we usually call "non-woven fabrics" and "melt blown fabrics" in combination
These materials in one, with anti-virus and dustproof double effect, so basically do not doubt the active carbon mask, anti - dust efficacy

The particles of powdered activated carbon used in the waterways are smaller than 0.1mm and the processing equipment can also use the original equipment, so many waterways can be used. All use of powdered activated carbon treatment. Rarely, usually used for removing the seasonal occurrence of the musty odor smell, etc., and the use of pesticides to get rid of surfactant, water source region, but also the use of water in trouble countermeasures as chemical material flow. The quality of powdered activated carbon used in waterways is clearly defined by the Japan Hydrographic Association specification.
Powdered activated carbon treatment of drinking water technology points: powdered activated carbon directly added to the raw water to be processed. This is to extend the touch time between the powder activated carbon and the target material as much as possible, and to improve the touch efficiency, it can also improve the removal function. Powdered activated carbon, which is removed from the target material, is treated by agglutination, precipitation, and sand filtration, and is removed with suspended matter in the water. As a channel maintenance policy, the use of powdered activated carbon (absolute dry carbon) shall be determined by the following elements.
Water odor and odor treatment measures, powdered carbon out of odor, when 5, 25mg/L;
When removing the precursor of three halogen methane, it is 30~100mg/L;
When removing phenol, it is 10 1 100mg/L;
When the anionic surfactant is removed, the amount of powdered activated carbon is about 20 times the concentration of anionic surfactant.
The above values are generally standardized. As a result of the removal of powdered activated carbon can vary with the type of activated carbon, etc., after all, according to the test and other resolutions, the share of activated carbon.
