The study was designed primarily coagulating sedimentation process, therefore, flocculation and sedimentation process is focused on the object of research, technology, etc. These processes are not within a wide range of this scope, we are a small part of the process which is the object , coagulation and sedimentation process to the treatment process is relatively important part of the natural water contains various impurities, such as: a variety of suspended solids, colloidal and dissolved solids. Presents an excellent degree water, turbidity, odor, etc. Coagulation and sedimentation process precisely these preliminary processing of natural water, to prepare for subsequent in-depth treatment.
Key Words: Coagulation and sedimentation,flocculation and sedimentation tank; inclined tube sedimentation tank; experimental operation to run.
