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...

Factor Xa and thrombin, two critical pro-coagulant enzymes of the clotting cascade, are the primary target of current anticoagulation research that aims to develop potent, orally bioavailable, synthetic small-molecule inhibitors. To determine structural features that might play important roles in factor Xa and thrombin recognition and oral bioavailability, quantitative structure-activity and st...

Organ transplantation and perfusion studied indicate that the spleen plays an important role in the regulation of plasma levels of factor VIII-von Willebrand's factor (FVIII-vWF). To better understand the mechanisms that regulate the FVIII-vWF increases after infusion of 1-deamino-8-D-arginine vasopressin (DDAVP), we have measured factor VIII coagulant activity (FVIII:C) and antigen (FVIII:CAg)...

Abstract This paper reports the effectiveness of chemical coagulation and biological techniques for treatment wastewater from industrial agricultural operations. Agricultural husbandry has been reported to produce that high content oxygen demand (COD), (BOD), turbidity as well organic inorganic pollutants. A comparison on use based coagulants optimum conditions required percentage removal effic...

background: untreated leachate is being discharged into the environment in many countries worldwide. leachate treatment methods have not been unified so far due to the variable composition of leachate. moreover, the lack of appropriate treatment and disposal of leachate causes environmental pollution. this study aimed to compare removal efficiency of chemical oxygen demand (cod) and total suspe...

Due to their cost-effectiveness, low toxicity, and naturally renewable properties, bio-coagulants for water treatment are gaining popularity. In this context, four were tested ability in turbidity reduction a synthetic bentonite suspension: Opuntia ficus indica (OFI) Moringa oleifera (MO) seeds, two well-established vegetal materials the domain of bio-coagulation, Algerian Aloe vera (AV) Pinus ...
