Wastewater treatment is a process, which is being done on the wastewater to change its quality for drinking or other suitable purposes. Wastewater treatment takes place in wastewater treatment plants, which should be designed under different circumstances. The criteria are being considered in this design for wastewater treatment plant (WWTP) Al-Hay. Moreover, the characteristics of physical, chemical and biological wastewater also are described. Based on the population of Al-Hay city, the project is undertaken to design a wastewater treatment plant. The girt chamber, equalization basin, oil and grease removal, aeration tank and secondary settling tank have been designed, and then the values for mean cell residence time, volume of aeration tank, hydraulic retention time, F/M ratio, return sludge flow rate, sludge production and oxygen requirement have been calculated. Modelling using GPS X also has been done on this data. It is exhibited a typical diagram of WWTP staring with influent flow, aeration tank and settling (clarifier) tank. The simulation time is also illustrated. With increasing the time, the parameters such as TSS and solids are typically enhanced. This is as indicator to improve the fit of the model and the actual data for the secondary effluent TSS. The research shows the treatment process design of Al-Hay wastewater treatment plant (WWTP). The paper also described the equations process design for WWTP. Sludge age (θc) has been calculated and associated to the observed yield (Yobs). There is correlation between sludge age and the mixed liquor suspended solid (MLSS). The value of the observed yield has been noticed, with values ranging from 0.2 to 0.6 kgVSS/kg(BOD5). The sludge retention time is equal to 27.7 day and the sludge produce is 3339.18 Kg/day. These results are related to biological tank for Al-hay WWTP is worked during with high efficiency.
