Table 1 showed the physicochemical parameters in both polluted and domestic water as per standard methods before the treatment. The pH of the polluted water was 9.2, TDS was 1873 mg/l, TSS level was 7.5 mg/l, alkalinity was 733 mg/l and hardness was 476.5. mg/l. The physic-chemical parameters of domestic waste water were as followed: pH was 8.5, TDS, 10200 mg/l.TSS ranged about 19.50 mg/l, alkalinity was 2125 mg/l and hardness 476.5mg/l. The comparative pH values of polluted and domestic waste water after treatment with activated carbon was shown in Figure 1.The pH of the polluted water and domestic waste water decreased after three weeks of treatment with activated carbon.
