Raw wastewater sludge samples were collected from two sanitary point sources in Zakho city wastewater pipes.Anaerobic digestion is utilized sludge stabilization as it was effective in reducing the volume of sludge and cheap source of clean biogas.the sludge of municipal wastewater of Zakho district is worth to be used for the generation of biogas a
Temperature plays an important role in daily life, industry production and scientific experimentation.However, because of the multi characteristics of nonlinearity, large lag, and time-varying of control objects, there will be great difficulties in establishing accurate mathematical models with mathematical methods.In order to achieve well controll
