| Abstract | ||
| This study has been evaluate of sewage efficiency treatment station in Najaf city, a period from 1/1/2008 to 31/12/2008, the limits of environmental pollution from station before draining it to the river were evaluated comprise biological oxygen domain (BOD), chemical oxygen domain (COD), phosphate ion (PO4-3), sulphate ion (SO4-2), nitrate (NO-3), chloride ion (Cl-), ammonia (NH3) greasy and oils. We noticed that the station efficiency to from (BOD) and (COD) to 81.5% and 76% respectively, TSS was 66%. Generally the station is working in good efficient, so the design energy 35000m3/day and the energy average 28000m3/day and the flow rate of water to station 24000m3/day. | ||
