DIN EN 15799:2010-05 EN 15799:2010 (E) 8 Annex A (informative) General information on powdered activated carbon A.1 Origin A.1.1 Raw materials Powdered activated carbon can be produced from virtually any carbonaceous material, e.g. coal,
39、lignite, peat, coconut shell and wood. A.1.2 Manufacturing process The carbonaceous material is subjected to controlled oxidation during which a highly porous structure is developed. The raw material is activated, thermally (most commonly) or chemically. Thermal activation involves heating to betwee
40、n 800 C and 1 100 C in the presence of an oxidizing gas (usually steam) under carefully controlled conditions for several hours. Chemical activation involves heating to between 400 C and 700 C in the presence of a dehydrating agent (e.g. phosphoric acid). After activation the material is cooled, the
41、n prepared, e.g. by pulverizing and sieving to extract the desired particle size, and packaged. A.2 Properties For the particle size range, the density, the chemical composition and the adsorption properties, see the relevant subclauses in Annex A of EN 12903:2009. A.3 Use A.3.1 Function Powdered ac
42、tivated carbon is used as an adsorbent for the removal of trace organic contaminants (e.g. pesticides, chlorinated solvents, oils), taste- and odour-producing compounds and trihalomethane precursors. It may be used in preference to granular activated carbon particularly to deal with seasonal or inte
43、rmittent problems. A.3.2 Form in which the product is used It is used as delivered. A.3.3 Treatment dose The treatment dose is typically in the range 5 mg/l to 50 mg/l (normally less than 20 mg/l) dependent on pool water quality, treatment objectives and type of filtration (conventional filtration o
44、r ultrafiltration). DIN EN 15799:2010-05 EN 15799:2010 (E) 9 A.3.4 Means of application Powdered activated carbon is dosed as a slurry into the water and removed by subsequent treatment processes (coagulation/flocculation, sedimentation, filtration or ultrafiltration). Dosing equipment should be sel
45、ected so as to avoid the possibility of overdosing. A.4 Rules for safe handling and use It is recommended to handle the product so as to avoid dust formation. Powdered activated carbon preferentially removes oxygen from air. In closed or partially closed containers and vessels, oxygen depletion can
46、reach hazardous levels. If workers are to enter a vessel containing carbon, appropriate sampling and work procedures for potentially low-oxygen areas should be followed. Certain types of chemically activated carbon might have special requirements for transport and storage in bulk; advice should be s
47、ought from the manufacturer. Local regulations can require transfer equipment to be electrically grounded to avoid ignition/explosion of dust by discharge of static electricity. A.5 Emergency procedures A.5.1 First aid In case of skin contact, it is recommended to wash with soap and water. In case o
48、f eye contact, it is recommended to flush with plenty of water for 15 min. In case of inhalation, it is recommended to move to fresh air. A.5.2 Spillage It is recommended to sweep or to vacuum unused carbon and to discard in a refuse container or repackage. A.5.3 Fire Any extinguishing media can be used; it is recommended to use foam extinguishers. Self-contained breathing apparatus should be worn because carbon dioxide and carbon
