This study presents a research about the ability of using substances that are relatively cheap and can be made from local materials to replace the activated carbon that is used in color removal of some industrial wastewater, the most recognized one is the textile industrial wastewater, which their effluents contains pigments that cannot be disposed to the water stream unless special specifications are met and that will happen after special treatment with activated carbon filters are done to remove these pigments.Many local substances had been chosen in this study to transfer in to granular activated carbon by using the incineration in absence of oxygen method in a temperature that is not less than (800)° C., and it was seen that the Date Palm frond stems has the ability to be converted in to carbon and can be activated effectively in this method, and it has been used in construction of an activated carbon filter which has a constant diameter with different activated carbon pack heights, and then a solutions of a basic textile industry pigments that is used in cloth dying which are, reactive red dye, methylene blue dye and methylene orange dye which all are considered the hardest pigments to remove, and these solutions were made with different concentrations, and were passed in to the local material activated carbon filter one time and to an original activated carbon filter the other time with increasing the filter pack height each time .The sampling process from the effluent were made three times for each pigment concentration and the concentration of the pigment were detected using spectrophotometric equipment average value were taken and then the average value was calculated and the removal efficiency then obtained, this process were made seventy two times, twelve times using the local material activated carbon and another ones using the original activated carbon for three concentrations for each dye for four carbon heights.A non-linear singular regression analysis statistical method were adopted to find the relationships between the independent variables (activated carbon bed height) and the dependent variable ( dyes removal efficiency ) with the concept of comparing the results of removal efficiency of the local activated carbon with the original one by finding the best fit curve for each concentration to each dye.From this research it was concluded that the usage of activated carbon that is made from Date Palm frond stems gives the same removal efficiency results for the dyes that are considered industrial water contaminants as if an original trade mark active carbon is used when the pack height is (0.3) m and above, and the research also showed that the cost of producing (1) m3 of the local activated carbon is less than exporting the activated carbon by (72.68)%, as well as, this method, if adopted, will ensure that the orchard trimmings will be transformed in to a useful material and will reduce its harmful uncontrolled incineration or its environmentally unfriendly disposal effect.
