AC series activated carbon filter is a more commonly used water treatment equipment. Activated carbon filter material is used as a filter bed to adsorb and remove abnormal colors, odors, colloids, pigments, heavy metal ions, etc., and it also has a function of reducing COD to a certain extent.
Overview of principles
Activated carbon is currently the most widely used active adsorbent. It has micropores of various shapes in the middle of its lattice structure, forming a unique multi-void structure, which constitutes a huge adsorption area, so the adsorption area is very strong. The activated carbon filter effectively removes organic impurities, colloids, heavy metals, residual chlorine and other undesirable impurities in the water by means of adsorption filtration to reduce the color of the water. euhowblog.com/Widely used in water purification of factories and towns, as well as the pretreatment process section of reverse osmosis, ultrafiltration, ion exchange system and improve the water quality of various deep purification equipment.
Activated carbon is made of coal, charcoal, fruit core, and nut shell, etc., and is made through carbonization and activation treatment. It has a large specific surface area. When activated carbon is used for deoxidation, hypochlorous acid is adsorbed on the surface of activated carbon and decomposed into hydrogen chloride and atomic oxygen. Atomic oxygen and carbon atoms have an adsorption state that quickly changes to a compound state, so there is no adsorption saturation problem with dechlorination of activated carbon. euhowblog.com/ just loses the amount of carbon. Activated carbon is not only capable of dechlorination, but also widely used to filter out residual suspended matter, humic acid, colloids, heavy metals, odors, etc. from water.
The bottom of the activated carbon filter should be filled with a quartz sand cushion. The size of the quartz sand can be 8-16 mm. The cushion is filled with granular activated carbon as the filter layer. The thickness of euhowblog.com/ is generally 800-1200mm.
Activated carbon regeneration usually uses thermal regeneration method, that is, activated carbon under the high temperature of 500-1000 ℃, the organic matter on the surface of the activated carbon is decomposed into carbon dioxide and water; you can also use high-pressure steam suction or sodium hydroxide solution for regeneration.
