This research work addressed laboratory study for biological treatment of phenol. Figuring phenol disintegration will give an idea of biodegradation of most organic chemicals since it is included in the composition of most of them. Biological treatment is considered one of the effective and economic ways to address phenol treatment by biodegradation as compared with high cost methods of physical and chemical processing. The method is of low efficiency when applied to high concentrations, in addition to formation of secondary compounds that may be more dangerous than the target material The study focused on use of three isolates, i.e.

Wastewater emerging from poultry technical slaughterhouses is characterized by its high degree of pollution in terms of organic content. This causes a rise in organic load disposed to wastewater treatment plants and thereby drooping efficiency. Effective and economical ways to treat such wastewater, based on reducing concentration of organic loads to appropriate level, preserves environs and reduces treatment costs for owners of industrial plants without augmenting investment costs. Aerobic Moving Bed Biofilm Reactor (MBBR) technology based on biofilm phenomenon is advocated in this research work.

Protection engineer is concerned with limiting the effects of disturbances in a power system, which if allowed to persist; many damage to plant and interrupt the supply of electric energy. These disturbances are described as three phase and single phase short circuits. In order that a fault study by using computer application can be successfully completed, the selection and application of the protective systems (relays, setting) have been carried out at SWEDIEH POWER PLANT AND SUBSTATION. This corresponds with the abnormal conditions and control circuit breakers so as to isolate the faulty section of that system in order to protect the electrical devices with SPEEDY, SELSCTIVITY, RELIABILITY COORDINATION and minimum interruption to service which is the main objective of this research.

Mathematical modelling plays a fundamental role in all science domains. By using it, we can construct mathematical models of several problems. Solving these models, mostly, depends on approximate methods, and when these models are represented by system of linear or nonlinear equations, the most equations have no exact solution .It is necessary to search for approximate solution by using numerical method such as Gauss, Gauss.Zaidl, Fixed Point, Newton, and Broyden methods. Beginning from an elementary value, which is chosen by estimation, and depending upon it to determine the speed of convergence and accuracy of the solution which we get by a certain accuracy.

Mathematical modeling is used in different science domains. By using it we can construct several mathematical models. Solving these models, mostly, depend on numerical approximate methods, and especially the case when these models are represented by the system of linear or nonlinear equations. To solve these equations we depend on generation solutions with repeated forms such as Gauss, Gauss. Zaidl, Fixed Point, Newton, and Broyden methods.
