in the current study, the efficiency of starch and plantago ovata extract as coagulant aids is compared in water turbidity removal. the coagulant is ferric chloride and the experiments are run in two ranges of ph 7 and 8. the achieved results of turbidity removal in different turbidity levels of 100, 50 and 20 ntu caused by different concentrations of starch and p.ovata as coagulant aids besid...

Published researches about the pretreatment of exit wastewater from desalination units are rare. Nowadays, lake of potable water, development of industries and population growth, extend desalination units. Although desalination units have been grown up, but exit brine stream is usually drained into the sea ecosystem [1-4]. Moreover, annually a large quantity of concentrated brine is discharged ...

Previous studies have shown that stimulation of whole blood or peripheral blood mononuclear cells with bacterial virulence factors results in the sequestration of pro-coagulant microvesicles (MVs). These particles explore their clotting activity via the extrinsic and intrinsic pathway of coagulation; however, their pathophysiological role in infectious diseases remains enigmatic. Here we descri...

Sulphated polysaccharides with anti-thrombotic and anti-coagulant activities have been found in various marine biota. In this study, a previously characterised anti-thrombotic and anti-coagulant extract from blacklip abalone was fractionated by anion exchange chromatography (AEC), pooled (on a sulphated polysaccharide basis) and administered to Wistar rats via oral gavage (N = 8) for assessment...

This study is on the reuse of the residue generated by a Moringa oleifera oil extraction plant. The residual oil cake produced during the process of oil extraction retains the positively charged protein of the M. oleifera seed, which is the active component in the process of 15 attracting and capturing suspended particles in waters. Such coagulant–flocculant properties give rise to the eliminat...

• UF coagulant dose controller was successfully developed and field tested. • Self-adaptive in-line UF coagulant dosing reduced coagulant consumption. • Real-time tracking of fouling resistance and backwash effectiveness. • Robust UF operation during conditions of deteriorating source water quality. ⁎ Corresponding authors.

introduction: the objective of this study was, wastewater quality investigation and removal efficiency of contaminants from the wastewater tile factory by using  coagulants includes ferric chloride, ferric sulfate and ferrous, aluminum sulfate and poly aluminum chloride in order to reuse it in the processing line. methods: this is an applied study. with regard to shiftwork schedules of the fact...

Coagulation –flocculation process remains a very essential part in the water treatment chain. It involves both physical and chemical phenomena and hence susceptible to high percentage of errors due to human factor. In order to reduce this percentage error and obtain optimal treatment efficiency, an intelligent coagulant dosing based on Artificial Neural Network (ANN) was proposed. Design of the...

Factors affecting the coagulant activity of two different prothrombin complex concentrates have been investigated using a sensitive in vitro assay developed in this laboratory. One concentrate contained substantial amounts of potentially thrombogenic material, while the other, which was deliberately fortified with antithrombin III and heparin during production, was judged to be relatively nonth...
