Integrally-skinned asymmetric Polyetherimide/Poly (vinyl alcohol) (PEI/PVA) hollow fber membranes for pervaporation dehydration were fabricated by non-solvent induced phase inversion. PVA inside the PEI matrix could be crosslinked to provide membrane performance stability during long term operation. The effects of different PEI/PVA blend ratio, external coagulant type and...

Nonfat (0% fat), reduced-fat (11% fat), and control (19% fat) mozzarella cheeses were made using direct acidification to test the influence of three levels (0.25X, 1X, and 4X) of coagulant concentration on proteolysis, meltability and rheological properties of cheeses during 60 d of storage at 5 degrees C. Changes in meltability, level of intact alpha(s1)-casein and beta-casein (by capillary el...

the research aimed to apply the taguchi method for techno-economical evaluation of cr+6 removal using the electro-coagulation process with the aid of two different coagulants (fecl3 and pac). taguchi orthogonal array l27 (313) was applied for analyzing the effect of four variables including initial ph, reaction time, current density and coagulant types in an attempt to improve the chromium remo...

Introduction Acute Lung Injury (ALI) and Acute Respiratory Distress Syndrome (ARDS) are characterized by a promptly release of proinflammatory mediators that downregulate natural anticoagulant mechanisms, initiate the coagulation system, impair fibrinolysis and produce the rupture of the endothelial and epithelial monolayer [1]. Inflammation of ALI/ARDS is initiated and strongly regulated by pr...

Although the removal of colloidal particles continues to be an important reason for using coagulation, a newer objective, the removal of natural organic matter (NOM) to reduce the formation of disinfection by-products (DBPs), is growing in importance. Enhanced coagulation is thus introduced to most water utilities treating surface water. Bench-scale experiments were conducted to compare the eff...

The scarcity of water has become a growing problem worldwide. search for new sources therefore intensified, and one these is greywater. objective this article to evaluate the effectiveness three different coagulants obtained from Moringa oleiferaseed (seed husk, ground seed, degreased) in synthetic methodology planned stages; first stage, seeds were selected, unsheathed, dried sun 24 hours, coa...

Background: Animal origin protein prices are beyond the purchasing capacity of average population. So for those who cannot afford costly available in market, plant source is very good choice e.g. Soybean. Many food scientists working on to enhance nutritive value milk products. In this investigation an attempt has been carried out sweetmeat with low cost production by using natural coagulant. M...

venom with serum and platelets resulted in a progressive increase in coagulant activity. Peden & Peacock (1958) found that ox serum was particularly active in potentiating the coagulant activity of the venom, and suggested that the venom acted enzymically on a substrate contained in the serum. The serum factor can be partially purified by adsorption on barium sulphate and elution by 0-2m-citrat...
