EFFECT OF DEFECATION STEPS ON CARACTERISTICS OF DRINKING WATERR IN MOLLA ABDOLLA STATION AND EVALUAT ITS EFFICENCY

Abstract

By this research we are studying molla abdolla water treatment plant ,which lays in molla abdolla town near by Kirkuk governorate. The station consists of the traditional liquidation (sedimentation ,filtration and sterilization ). Each of these three phases has been studying through physical ,chemical and biological testing).The results showed low efficiency of sedimentation through the removal of total suspended solids witch equal to 12% . The efficiency of filtration phase was 45.5% and (25-77)% for sterilization phase. For the characteristics of water quality were 7.6 for pH , 577 µs/cm for electro conductivity 306.7 mg/L for Total dissolve salt TDS ,8.5NTU for turbidity,44.8 for Total suspended solid TSS . All these results are within the Iraqi standard Limitation and world health organization except turbidity and TSS. The results of alkalinity were in continuous low ,and different values for total hardness T.H
