The Carbon Filter is shown in the figure. When the water passes through the Carbon Filter, the adsorbed material in the water is transferred from the liquid phase to the surface of the solid phase activated carbon. This process can be seen as the process of liquid diffusion, pore diffusion and adsorption of the inner surface of the three processes. Because activated carbon has a well-developed pore structure and a large specific surface area, so the solubility of water in a variety of organic matter has a strong ability to absorb, and the use of biological or other chemical method is difficult to remove organic matter such as color, Surfactants, synthetic detergents and dyes have a better removal effect. Activated carbon also has the role of removing residual chlorine, its adsorption of Cl2 not only physical adsorption, but also the role of chemical adsorption. The chemical adsorption principle is:
2Cl2 + C + 2H2O → 4HCl + CO2 Carbon Filter is to protect the follow-up ion exchange resin and separation membrane from organic pollution.
Carbon Filter is suitable for filtering chemical gas particles, the use of coconut shell charcoal or impregnated Carbon Filter can be highly effective adsorption of toxic gases.
Widely used in airports, archives, museums and semiconductors, chemical industry and so on. Can filter organic gases, acid gases, alkaline gases, depending on the application areas, you can use different types of Carbon Filter.

First, the characteristics of Carbon Filter
Activated carbon is made of carbon-based substances (charcoal, wood chips, coconut shell, walnut shell, coal) as raw materials, high temperature carbonization and activation of hydrophobic adsorbent made. Is a high carbon content, molecular weight of organic molecules agglomerates.
Features:
1), a huge adsorption surface area, strong adsorption capacity, good specific surface area of activated carbon in 1000m2 / g or more. The total volume of pores can reach 0.6-0.18 ml / g.
2) The adsorption capacity of activated carbon is generally physical adsorption as the main body, there is no polarity, renewable use.
Second, the regeneration of activated carbon
Active work for some time, to achieve saturated adsorption capacity, it should be renewable recovery, in order to repeat the application. Regeneration method is the use of high temperature pyrolysis regeneration, the regeneration cost of 4,000 yuan / ton. Year. Times, carbon loss rate of 5.1%, regeneration effect of about 90%.
Third, the Carbon Filter device instructions
1 Overview
This equipment is pressure Carbon Filter. The device can be filtered to remove suspended solids in water, but also adsorption to remove organic matter in water. Water filtration rate is generally 8 to 10 m / h; activated carbon layer is 1.2 meters high, backwashing strength of 12 to 14 liters / second.
2, the use of activated carbon in water treatment system conditions
1), the application of water conditions: into the Carbon Filter water should try to remove large particles of suspended solids and colloidal substances to prevent clogging the pores of charcoal and charcoal pores blocked to improve the adsorption of activated carbon effect, the general requirements into Water suspension is less than 3 to 5 mg / l.
2), activated carbon pretreatment: granular activated carbon into the filter should be soaked in water, rinse to remove dirt.
