The worldwide demand for activated carbon is predicted to reach 1.2 hfllion by 2007 of which 56% is expected to be consumed ty North America, Western Europe, and Jtqpan [11], However, due to some over-production, the wcn-ld prices for activated carbon have lowerd over the last decade [12], More detailed data on world demand for activated carbon is presented in Figs. 1 and 2, and the major manulacturas of the activated carbon and their plant capacities are listed in Table 1.

Activated Carbon Filters and their Industrial Applications... 

Loosely filled granulated activated carbon is better suited to large deep-bed filters, which often require media depths of up to 1 m. Low depth, loosely filled filters can prove less effective due to their tendency to settle and allow the air to bypass the activated carbon medium or for the activated carbon itself to escape from the filter in the air stream and form into carbon dust. Loosely filled systems will almost always be specified for highly contaminated applications, such as some industrial processes, where deep-bed filters are required.
