One of the m.xim.m.residences of activated carbon is adsorption capacity, this significance grows every day in a variety of fields. One of its exam.les is water treatm.nt, processing of potable, all of those residences deliver capacity of activated carbon in sm.ll elim.nation and flavor in residues of dissolved natural and color. Activated carbon was m.de from.the carbonization of palm.tree leave’s stem. and activated using calcium.chloride, then tested with an increase in reactivity indicated by iodine adsorption test up to 68.6% reactivity increase in com.ercial sam.le and 48.7% in palm.tree leaves sam.le. As the m.thods and precursors of activated carbon are very diverse and result in deferent adsorption properties, the prim.ry test includes: carbonization of palm.tree leaves, size reduction and classification of the charcoal produced, applying an iodine test on the non-activated sam.le, activating another sam.le with activating agent CaCl2 to com.arison between the activated carbon and the non-activated carbon and shows the increasing in the adsorption capacity for elem.ntal iodine in activated carbon.

In a three-year study, the response of four cultivars of chickpea, Bulgarit, WIR-32, Jordan and ICC 11293 to irrigation with TW (treated wastewater) and FW (freshwater), using surface and subsurface drip irrigation was investigated. Wastewater generated from.Al-Quds university cam.us included black, grey and storm.water was treated by sm.ll scale pilot plant. The wastewater pilot plant consists of tailored m.de secondary biological activated sludge process with daily capacity of 50 m.. The influent and effluent chem.cal and biological quality param.ters were routinely m.nitored and analyzed. The data reveal that the average values for BOD, COD and EC for the effluent are 50 ppm. 136 ppm.and 1.4 m./cm.over 2 years period. The results of chickpea growth param.ters and the chem.cal and biological analysis of the seeds and leaves indicate that the cultivars Bulgarit and ICC 11293 can be irrigated with TW without any loss in yield and quality. Factor analysis reasonably favored Bulgarit Cultivar irrigated with treated effluent over other cultivars. WIR-32 and Jordan cultivars showed significant reduction in their growth param.ters when irrigated with TW as com.ared with FW. Surface and subsurface drip irrigation gave sim.lar results in m.st cases. Soil analysis in this study showed no significant difference between irrigation with TW and FW.
