The role of activated carbon filter in water treatment industry analysis - 【 3 m filter.

Important filter material is activated carbon, activated carbon filter in the filter material is pure water main, use more adsorption material. Is mostly used in water purification machines, water purification machine filter. Activated carbon is made such as coconut shells, fruit shell as raw material, through carbonization, activation, crushing, screening, air separation, drying and other processes. In the early 1930 s, people use activated carbon adsorption of phenol in waste water from coking plant, as a result, the application of activated carbon in water treatment has a history of nearly eighty years.

activated carbon filter is a new kind of deep filtration components, after special processing forming, micro pore structure. Its adsorption performance is good, effectively overcome all carbon powder leakage defects in granular activated carbon filter, suspended solids, organic matter in at the same time, in addition to the fluid particles, rust, residual chlorine, peculiar smell, etc.

activated carbon filter adsorption capacity and adsorption speed is the main indicators of the adsorption process. The size of the adsorption capacity is measured by adsorption, the adsorption rate refers to the unit weight of adsorbent adsorption in unit time quality. In water treatment, sewage needs and adsorbent adsorption speed determines the contact time.

in general, the filters filter particles is smaller, the faster the pore diffusion, the stronger the activated carbon filter adsorption ability. Wastewater pH value and temperature also has effect on the adsorption of activated carbon. Activated carbon under acid condition in general than in alkaline conditions have higher adsorption capacity. Adsorption is usually exothermic reaction, so low temperature favors the adsorption reaction. Of course, activated carbon adsorption ability related to the sewage concentration. In a certain temperature, activated carbon adsorption quantity varies with the increase of concentration of adsorption material balance.
