Application of the activated carbon is widely used, it is also The water purifier filter part. So, what role to play in the activated carbon water purifier? What are its advantages and disadvantages? Together under the understanding of it!
Water Purification disadvantage of activated charcoal purification
1, purification of active carbon
Activated carbon can remove water and olfactory taste, color, chlorine, colloids, organic (synthetic detergents, pesticides, herbicides, insecticides, synthetic dyes, trihalomethanes, haloacetic acids, endocrine disruptors such as phthalate PAES etc.), heavy metals (such as mercury, silver, cadmium, chromium, lead, nickel, etc.), radioactive substances, used in the water purifier is the earliest and most widely practical water purification materials. Usually only activated purifier, home reverse osmosis in the of pure water, and most ultrafiltration, ceramic, KDF, UV water purifier, etc., will be used activated carbon.
Activated carbon and KDF can remove chlorine, but chlorine reacts KDF and zinc ions (AND Zn2), the water may cause excessive zinc, and then treated with activated carbon dechlorination no such fear.
Activated carbon is formed during the activation of a large number of fine holes of various shapes to form a large surface area with adsorption, the specific surface area of ??500 ~ 1200m2 / g, the greater the surface area, the better the adsorption .
2, the negative impact of the activated carbon
(1) a large amount of organic carbon adsorption, these organisms can be bacteria and other microbial nutrients, bacteria will multiply in the proliferation of microporous activated carbon, and may result in the total number of colonies exceeded the water.
(2) activated carbon in the water purifier at microbial catalyst, the ammonia into nitrite nitrogen in water, the water purifier often appear nitrite many times higher than water. Nitrite itself is not carcinogenic, but it reacts with water to form amines are strongly carcinogenic nitrosamines.
(3) the resin was added bromine (brominated polystyrene hydantoin) filter or UV filter sterilization activated carbon adsorption effluent exceeded microorganisms in water is a good way to solve.
above the water purifier activated carbon is about the role and the advantages and disadvantages of introduction, hope to help a friend in need to know, oh!
