Treated sea water is the most significant source of water and surfactant floods. The various chemicals employed in treatment plants should be compatible with surfactant systems. Based on surface tension experiments, the activity of these chemicals is examined over a wide range of concentrations in different solutions, including distillated water, sea water by using three types of surfactant mix...
This studyaims to treat kaolin synthetic wastewaterby using sludge from water treatment plant as a coagulant via the coagulation process. Water (WTS) was characterized by Fourier transform infrared (FTIR), Scanning electron microscope (SEM), and X-ray diffraction (XRD). WTS had an amorphous structure contained high aluminium metal constituents at 25.3%, which can be recovered coagulant. Acidifi...
Abstract Background: Factor VII, is a coagulant protease it begins the proteolytic cascade reactions and produces thrombin. The use of recombinant human factor VII, (rhFVII) is effective for the treatment of patients with hemophilia A or B. It is a target for gene therapy. This study was done to clone factor VII from HepG2 cell line. Methods: RNA was extracted from the hepatoma, (HepG2), ...
The goal of this study was to evaluate tannic acid as a coagulant in turbidity removal. Tests were designed using Taguchi method and carried out on the synthetic and natural turbid samples. In order to optimize turbidity removal by tannic acid, seven factors including pH, coagulant dosage, rapid mixing rate, slow mixing rate, slow mixing time, sedimentation time and initial turbidity were inves...
