Treatment of batik wastewater using granular physical coconut based activated carbon (GAC) / Tengku Fazilah Tengku Osman

Activated carbon is the generic term used to describe a family of carbonaceous adsorbents with a highly crystalline form and extensively developed internal pore structure. A wide variety of activated carbon products is available exhibiting markedly different characteristics depending upon the raw material and activation technique used in their production. It is also used as adsorbent to purify, decolourize and remove odour of wastewater. The Total Solid (TS), Suspended Solid ( SS ), Volatile Suspended Solid (VSS), Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) are important parameter for determining the water quality. BOD measures the amount of dissolved oxygen required by microorganisms. It is measured at 20° C under 5 days incubation. BOD value represents the carbon available for metabolic activity and indicates the extent of pollution. COD is the oxygen equivalent of the organic contents present in a water sample.
