Powdered activated carbon water purification, Kawazu charcoal, activated carbon filter Song Xin iodine value

 Molecular mass of activated carbon adsorption to activated carbon gravity posture transmission gap, can be divided into the following steps: 1, the external diffusion: chemisorption since transferred to the solution of the dispersed phase activated carbon adsorbent surface water from coal required by the process of the activated carbon adsorption membrane around and adsorbate molecules transferred to the surface near the sorbent. 2, the surface diffusion: adsorbate adsorbed along the outer surface of the activated carbon to pore diffusion process inside the three internal particle diffusion: adsorbate transferred to the position of the activated carbon adsorption holes inside the process. 4, physical adsorption: After contact with the activated carbon adsorbate, adsorbate molecules attached to the adsorption position, losing the freedom, then export adsorbate concentration decreases, and in the case of export concentration changes, to represent the adsorption rate. 5, desorption: adsorbate since active position out to regain the freedom, that is, since the removal of the internal pores of the activated carbon process, steps 4 and 5 when the reaction rate considerably, then the activated carbon adsorption quality reached homeostasis. 6, chemisorption: adsorbate and the adsorbent surface chemical reaction, depending on the nature and quality of the activated carbon adsorption is different. 7, the surface renewal: has been adsorbed on powdered activated carbon adsorption of water quality activated carbon, which is the product of a chemical reaction, a highly volatile carbon, fire and metal ion catalyzed hydrolysis, therefore since the removal of activated carbon, activated carbon adsorption capacity recovery powdered activated carbon bleaching rate, and can be used again. Typically external diffusion, surface diffusion and diffusion rate of diffusion within the particles of activated carbon adsorption rate decision, but in the liquid flow adsorption system, if the flow rate is too slow, too slow will cause convection, the internal particle diffusion rate of a liquid phase adsorption The controlling factor. 1, dusty pollution problems. Because of powdered activated carbon in many sectors such as loading, unloading, unpacking, formulation, dosing during labor intensive, prone to dust emissions, resulting in poor working conditions, as a constraint powdered activated carbon technology a key, substantive issues. Song Xin supply of quality wood powdered activated carbon, powdered activated carbon price consulting the latest wood 2, investment, cost control. Powdered activated carbon as an effective method of strengthening or wastewater treatment, waste water must be treated to ensure that water quality is better, try to extend the life cycle of the cycle, in order to reduce the amount of activated carbon, saving operating costs. 3, for the biological activated carbon pool, the total amount of carbon due to the growth of microorganisms in the bed space is limited, so only when the total amount of organic carbon bed adsorption in a unit time from the waste water down interception is less than the maximum microbial decomposition carbon bed regeneration, in order to maintain homeostasis, ensure long-term stable operation. General design should control water CODcr at 200mg / l or less, taking into account the setting across the tube, so as not to cause damage to the carbon bed is not easy to recover when the accident emissions. 4, to strengthen operations management biochar pools, development of relevant procedures. Strengthening the backwash and control the strength to prevent the loss of activated carbon; ensure continuous aeration during operation, no water or water may be appropriate to reduce gas volume is low.
