Coconut shell activated carbon filter in home water purifier purifying effect on coconut shell carbon filter is composed of coconut shell, shell and other raw materials for activated carbon, after charring (stew burning stove), activated (SLEP activation furnaces at 800 ℃ high temperature steam activation), crushing, screening, winnowing, washing, drying and other processes in the system is a coconut shell carbon filter household water purifiers the most important and most frequently used absorbent material (other absorbent material as well: neutral macroporous resin, macroporous anion resin, zeolite, diatomite, etc.). As early as the 1930s, people Activated Carbon Adsorption export coking plant waste water from coconut shell charcoal, coconut therefore activated carbon, coconut shell activated carbon water treatment The application has been nearly 80 years of history have recorded 1862 British coconut shell activated carbon to purify drinking water. Our first modern water purifier (Shanghai Fairchild water purification Technology Co., Ltd., 1986) is also based on coconut shell charcoal net water material. It can be said that since the birth of the water purifier, coconut shell carbon filter and household water purifiers have been 'inseparable', locked in. First, the classification of a coconut shell activated carbon, coconut shell activated carbon system based on different raw materials, coconut shell Activated carbon can be divided into: (1) wood charcoal: can be divided into charcoal (made from wood chips as raw material), charcoal (made of bamboo as raw material), husk charcoal (made of walnut or almond shells as raw material) , coconut shell charcoal (made from coconut shells as raw material), is commonly used in water purification coconut husk charcoal or charcoal. (2) coal carbon (made by the anthracite to produce better quality Ningxia). (3) Bone charcoal (made from animal bones). We look at the hazards of formaldehyde, formaldehyde in the end how much harm? Formaldehyde on the skin and mucous membrane irritant effects, such as the nose throat and eyes, etc., can easily lead to these locations edema, ulceration, and eventually lead to serious disease. Skin contact with formaldehyde may be allergic phenomenon, severe cases may even lead to kidney damage. Infants more serious harm pregnant women, can lead to fetal growth and development of activated carbon production stop during pregnancy, cardio-cerebral hypoplasia. The National Environmental Protection Agency classified formaldehyde as a possible carcinogen. Activated carbon and do not think it will work on the charcoal would not leave it. In fact, formaldehyde (also including other contaminants) release and absorption is the dynamic equilibrium. If a certain amount of activated carbon and no ventilation when the amount of formaldehyde will eventually stabilize at a value. There have been only in the case of an absorption source of new, concentration will decrease. Activated carbon is also effective absorption of formaldehyde on the premise that you have to prepare a large number of activated carbon, periodic replacement. The release of formaldehyde is an ongoing, slowing the process, do not expect anything except a one-time formaldehyde, hours effective.
