Wastewater treatment plant (WWTP) in Oman of Exploring Factors Causing Delays on Wastewater Projects in Oman

            The major of the treatment of the water is to removing the organic matter in the bulk from the water and it includes nutrients, proteins and carbohydrates. In the processes of the MBR and CTP the biological degradation and absorption of the integration of inorganics and organics by taking place the activated sludge. In suspension of the both systems the activated sludge contains on the    flocculating microorganisms and it held in the suspensions that can easily contact with the waste water which existed in the mixed arcade tank. To the treatment of the mechanical the influent wastewater is first submitted in CTP at where large particles from the water are removed easily. After completing this primary stage of the sedimentation the flow of then water becomes slower by than large tanks and the waste water is move towards the sludge tank that is biological activities. At last, by using the gravity sedimentation and separation step is achieved in additional in its external clarifier.

            The primary sedimentation and mechanical treatment is not carried out in the process of the MBR. The sludge is referred as the main difference among the MBR and CTP as well as the step of the liquid separation. The filtration step includes as the activated sludge tank by using the Nano and micro filtration membrane at where the solid particles are retained for the tank of aeration. The techniques of the separation of the biomass can significantly influences wastewater sewage quality. Usually at 1–5 g/l the suspended solids in the mixed liquor of the CTPs are operated although the concertation is relatively higher in the MBR that is ranges between 8 to 25 g/ even more.  The te4chnology of the MBR allows to the treatment of the sewage at high concentration MLSS because of the separation of the step of the membrane and it is not considered as limited by the capacity of the sedimentation minor clarifier.
