Abstract:
Over a period of five months (February 2007-June 2007) experiment was carried out to study the chemical characteristics of sludge resulting from Elmogran Water Supply as Organic Fertilizer Free from Pollutant Elements. A number of samples were collected. Analyses were done using Atomic Absorption and the total contents of metals were compared with Florida Soil Cleanup Target Levels (SCTLs). For example results showed that Cu 0.3172 mg kg-1 bellow the pollutant level 110 mg kg-1, Mn 0.1929 mg kg-1 bellow the pollutant level 1.6mg kg-1, Fe 0.1704 mg kg-1 bellow the pollutant level 23000 mg kg-1 . There-fore sludge consider free from pollutant elements and hence can be used as organic fertilizer
