The aim of the present work is to investigate potential use banana peel waste as a natural coagulant and enhance its coagulation performance using green modification approach for removal synthetic water turbidity river treatment. Here, regular powder had an average particle size diameter 978 ± 37 nm 602 13 nm, respectively, while modified possessed 571 41 360 19 diameter, respectively. was inve...

Swimming pools are examples of water-intensive facilities, where solutions for reducing economic and environmental costs searched with increased frequency. One the supporting savings is recovery water from wastewater, including backwash obtained while rinsing filter bed. The study objective was qualitative quantitative assessment post-coagulation sludges, main pollutant found in washings. Durin...

background: although stabilization ponds and lagoons are suitable treatment processes due to simplicity of operation and low per capital costs, the effluents of these systems have too high of a total suspended solids concentration to be discharged into receiving waters. this problem is mainly caused by algae. in this study, an electro-coagulation reactor was examined to re­move algae from the f...

Zeta sedimentation ratio (ZSR) is a simple, rapid and reproducible test which is not influenced by variables like sex and anemia. There is good correlation with Westergren erythrocyte sedimentation ratio (ESR) in normal and hospital population. Limitation of packing force affects the use of the procedure in polycythemia and in patients with ZSR greater than 80%.

Presence of salts in water has been one of the biggest problems of industrial equipment such as evaporators, boilers, and pipes. These salts gradually form scales on evaporators and boilers tubes and reduce their efficiency. Pretreatment processes are conducted to remove these salts; with sedimentation tanks being one of the essential equipment used in these processes. This study numerically si...

Methods 116 consecutive children with acute arthritis with symptoms duration < 6 weeks included in prospective study. A standardize rheumatologic evaluation was performed on newly referred patients. Possible diagnostic variables collected at the first visit: active joints count, symptoms duration, time of morning stiffness, erythrocyte sedimentation rate (ESR), C reactive protein (SRP), antinuc...

During the course of an investigation of the electrophoretic properties of extracts of human neoplastic lymphoid tissues, a distinctly abnormal component was observed in a case of lymphosarcoma. On examining the serum of this patient, it was found that lowering the temperature to 4” caused spontaneous precipitation of a large amount of protein, which redissolved completely when the serum was wa...

Introduction Cold plasma is a self-sterilized, painless, and non-contact method in surgeries. These properties allow it to be applied to the living tissues and heat-sensitive parts. The aim of this study was to design a new cold plasma producer device and evaluate the effects of cold argon plasma on decreasing the coagulation time of blood drop in vitro and that of the injured liver blood in vi...

Pre-sedimentation basins are among the most important elements of the conventional water treatment process. In pre-sedimentation basins, due to different velocity gradients, secondary and rotational flows are formed that will create short paths and increase dead and still flow zones as well as changes in the flow mixing. This will prevent laminar flow conditions for sedimentation and will reduc...
