A series of polyaluminum silicate chloride (PASiC) composite coagulants were prepared by two approaches: (1) hydroxylation of the mixture f AlCl3 and fresh polysilicate (PASiCc); (2) hydroxylated polyaluminum chloride (PAC) combined with fresh polysilicate (PASiCm). Laboratory xperiments were conducted to evaluate PASiC in comparison with PAC for the coagulation of water and wastewater and to i...

In the fishmeal industry, seawater is used to transport fish factories. Due this, “pumping water” with high concentrations of organic matter generated that treated via chemical coagulation before letting it into sea. The objective this study characterize and compare sludge obtained from conventional electrocoagulation process. A pilot plant was built next a plant. both methodologies analyzed fo...

The aim of the present work was to produce a polyaluminium ferric silicate chloride (PAFSiC) coagulant from acidic and alkaline wastewater of purifying graphite by roasting, and subsequently to evaluate coagulation efficiency of the reagent by treating surface water from the Yellow River as well as municipal wastewater in comparison with the conventional coagulant polyaluminium chloride (PAC). ...

Fractal dimensions of aggregates can potentially be used to classify aggregate morphology as well as to identify coagulation mechanisms. Microbial aggregates of Zoogloeu rumigera have a cluster fractal dimension of 1.8kO.3 (+ SD), suggesting that these aggregates are formed through cluster-cluster coagulation. An analysis of size-porosity correlations for two types of marine snow aggregates yie...

This article demonstrates that a simple chemical model system, built by using a modular approach, may be used to predict the spatiotemporal dynamics of initiation of blood clotting in the complex network of hemostasis. Microfluidics was used to create in vitro environments that expose both the complex network and the model system to surfaces patterned with patches presenting clotting stimuli. B...

This experimental study was conducted to investigate the effect of treatment of composting plant leachate by a coagulation-flocculation process. The effects of different dosages of coagulant and different pH values on the coagulation processes were compared. Ferric chloride and aluminium sulphate (alum) were tested as conventional coagulants. The experimental results show that a 18% removal of ...

According to the Ayurveda, plants have been used for treatment of so many diseases. Herbal drugs are easily available and fewer side effects. So, people attracted towards herbal drugs. Ocimum kilimandscharicum is one a few types basil that perennial. It well-known plant in Indian traditional system medicine. The genus belongs family Labiatae most popular culinary herbs known its medicinal prope...

Newly determined crystal structures suggest that the membrane-binding C2 domains of blood coagulation cofactors Va and VIIIa bind anionic phospholipids through protruding solvent-exposed hydrophobic residues, aided by a crown of positively charged residues and by specific hydrogen-bonding side chains.

 It has been recognized that patients with Cyanotic Congenital Heart Disease (CCHD) show significant bleeding tendency which can be secondary to coagulopathies in these patients. Some coagulation abnormalities are thrombocytopenia, factor deficiencies, fibrinolysis and Disseminated Intravascular Coagulation  (DIC). According to high prevalence of CCHD and major operations in theses patients, th...
