The first water treatment plant in which granular activated carbon adsorption tank used was built in 1930 in Philadelphia, United States[1]. In the 1960-1970s, developed western countries started to use activated carbon technology in potable water treatment to enhance the removal of organic contaminants.

Hence, this research examines the adsorption and treatment of dissolved organic pollutants in wastewater from a refinery in Nigeria using granular activated carbon produced from waste Nigerian bamboo.

ADSORPTION CAPACITY. The specific capacity of a granular activated carbon to adsorb organic compounds is related to: molecular surface attraction, the total surface area available per unit weight of carbon, and the concentration of contaminants in the wastewater stream. The basic instrument for evaluating activated
with granular activated carbon (GAC)typically in a semi-batch or continuous operation. Processes that utilize this type of carbon include: 1. Fixed-bed or expanded-bed adsorption. 2. Moving-bed adsorption. 3. Fluidized-bed adsorption. Adsorption Processes Utilizing Granular Activated. Carbon for Waste Water Treatment
Carbon used for adsorption is usually treated (activated) to make it very porous. Two types of activated carbon are: powdered activated carbon (PAC) and granular activated carbon (GAC). PAC is added to industrial wastewater sludge systems to adsorb toxics and in some cases, as a secondary effect, biodegrade compounds.
23 Sep 2011 This monograph provides comprehensive coverage of technologies which integrate adsorption and biological processes in water and wastewater treatment. The authors provide both an introduction to the topic as well as a detailed discussion of theoretical and practical considerations. After a review of the

adsorbents can be found in Chapter 2. Activated carbon is the most important engineered adsorbent applied in water treatment. It is widely used to remove organic substances from different types of water such as drinking water, wastewater, groundwater, landfill leachate,. Table 1.1 Adsorption processes in water treatment.
