The massive growth of potentially toxic cyanobacteria in water supply reservoirs, such as Legedadi Reservoir (Ethiopia), poses a huge burden to purification units and represents serious threat public health. In this study, we evaluated the efficiency flocculants/coagulants chitosan, Moringa oleifera seed (MOS), poly-aluminium chloride (PAC) settling cyanobacterial species present Reservoir. We ...

This study investigated the efficiency of LENFLOC™ production using a microwave-assisted continuous-flow grafting process. The discussed contribution plant-based coagulants for water and wastewater treatment toward circular economy in treatment. Lentil waste extract was used to produce (2-methacryloyloxyethyl) trimethyl ammonium chloride with 75 wt.% on H2O as chain monomer cerium nitrate (≥98%...

Surface water pollution has increased, owing to industrial development and population growth. Consequently, it is important find alternative drinking treatment strategies, which cater for changes in the quality of raw water. This study compared efficiency different coagulants treating that feeds a plant (WTP). Using jar testing equipment number physicochemical parameters, an investigation was c...

This abstract presents a laboratory study of a coagulation/flocculation process on an urban snow melt mixture. Coagulation/flocculation is ubiquitous in water treatment, but has seen little use in the stormwater context. Using a jar-test procedure five different chemicals are evaluated as primary coagulants and their treatment performance on urban snow melt with respect to solids removal and me...

In order to maintain an anticoagulant nature, the healthy endothelium secretes factors such as tissue plasminogen activator, ADPase, and expresses membrane thrombomodulin. However, when damaged, it releases increased amounts of pro-coagulants such as von Willebrand factor. Similarly, the healthy endothelium uses nitric oxide, prostacyclin and other molecules to help maintain normal blood pressu...

A 21-year-old man presented with acute-onset left lower abdominal pain that had initially developed 8 hours earlier. He was not given any medication including anti-coagulants. He denied trauma. On palpation, the left testis was slightly swollen and showed tenderness. The suspected diagnosis was testicular torsion, and surgical exploration was indicated. On visual inspection, the whole testis wa...
