The present study is focused to optimize the coagulation process for treatment of water sourced from the Palar River Basin and supplied to the Vellore Municipality. The research was progressed to evaluate the water treatment efficacy of natural coagulant i.e. moringaoleiferaseed, available locally in abundance, as well as conventional coagulants viz. alum and ferric chloride. Primly the basic o...

Abstract For turbidity removal, most drinking water treatment plants are using coagulants due to the presence of suspended and colloidal materials at coagulation flocculation units. Aluminium sulphates salts widely used coagulants, such as aluminium sulphate (Alum) ferric chloride. However, several researches have linked Alzheimer's disease use sulphate. Hence, scholars conducted on possibility...

the objective of the research was to test the effect of iron and aluminium coagulants commonly used for lake re-cultivation, on the pike sperm motility and fertilisation. the coagulants caused changes in the analyzed hydrochemical parameters of the water such as: fe, mg2+, tss, so42- and cl-. selected parameters of sperm motility: mot, vcl, vsl, vap, lin were estimated using casa. the sperm mot...

Hydrolysis and precipitation are the key processes that determine coagulation performance of inorganic metal salts. The valence concentration salts, ligands, solution pH all influence performance. In order to get a full picture on pros cons various salts as coagulants, this paper conducted thermodynamic equilibrium calculations experiments analyze verify hydrolysis-precipitation a...

Seeds of the plant species Strychnos potatorum and Moringa oleifera contain natural polyelectrolytes which can be used as coagulants to clarify turbid waters. In laboratory tests, direct filtration of a turbid surface water (turbidity 15-25 NTU, heterotrophic bacteria 280-500 cfu ml(-1), and fecal coliforms 280-500 MPN 100 ml(-1)), with seeds of S. potatorum or M. oleifera as coagulant, produce...

We describe a perfusion-based microfluidic device for three-dimensional (3D) dynamic primary human hepatocyte cell culture. The microfluidic device was used to promote and maintain 3D tissue-like cellular morphology and cell-specific functionality of primary human hepatocytes by restoring membrane polarity and hepatocyte transport function in vitro without the addition of biological or syntheti...

This article focuses on rapid diagnosis and treatment of the patient suffering from trauma-related shock, including early identification of patients at risk for occult hypoperfusion. Resuscitation strategies (delayed resuscitation, damage control resuscitation), end points of resuscitation, and the role of blood products and pro-coagulants for resuscitation are discussed.

The hydrolysis of Al-based coagulants in acidic conditions is necessary for the removal of organic matter by the coagulation/sedimentation process. However, interactions between hydrolyzed Al species and organic matter are complicated and this makes it difficult to optimize coagulant dosing for organics removal. The goal of this study was to investigate the reactions of hydrolyzed Al species in...

Atrial fibrillation (AF) continues to impose a significant burden upon healthcare resources. A sustained increase in the ageing population and better survival from conditions such as ischaemic heart disease have ensured that both the incidence and prevalence of AF continue to increase significantly. AF can lead to complications such as embolism and heart failure and these acting in concert with...
