Powdered activated carbons (PAC) are defined by the ASTM as particles passing through an 80mesh sieve ( mm) and smaller. Calgon Carbon Corporation manufactures many types of powdered activated carbon products each specifically engineered to provide a unique pore structure and adsorption properties. By varying manufacturing conditions
201671 · The production of 1 tonne of activated carbon (functional unit of the study) needs about tonnes of coconut shells. The assumed composition of coconut shell ( Table 1) was that reported by Woodroof ( Woodroof 1979 ) which is in close agreement with the elemental composition utilized by Fagbemi et al. (2001).

· Activated carbon remains the most common method used to decolor vinegar (Achaerandio et al. 2002). Activated carbon can also be used to remove ethylene from fruit storage facilities particularly if brominated (Reid 1985). The primary use for activated carbon is the treatment of water including potable water (24 of all use) wastewater (21 )
· The dosage of powdered activated carbon can be easily increased or decreased as process conditions vary. Powdered activated carbons are mainly used for liquidphase adsorption. They are added to the liquid to be treated mixed with the liquid and after adsorption are removed by sedimentation and filtration.

· The use of granular activated carbon (GAC) for water purification became common around the start of the 20th century (1906) when the "activation" process was applied to charcoal (which had been used for centuries). Thermal activation of charcoal
202178 · The surface areas and poresize distributions of the activated carbon samples were measured via the physical adsorption of nitrogen gas at Ð196oC using a surface area and poresize analyzer (Sorptomatic 1900 Carlo Erba Italy). The adsorption value of the activated carbons towards Activated Carbons Prepared from Sawdust by Chemical Activation 535
powdered activated carbon are derived from either hard wood charcoal or pine wood charcoal. naturally therefore these carbons are vegetable origin. in the activation process the super heated steam reacts with wood charcoal (water gas reaction) and opens up fresh spaces in
201734 · ACTIVATED CARBON AND BIOGAS PRODUCTION IN TREATING PALM OIL MILL EFFLUENT ABSTRACT Anaerobic membrane bioreactors (AnMBRs) have been widely used to treat wastewater and powdered activated carbon (PAC) is found as a good material with its adsorption ability.
