Calcium is also required at other points in the coagulation cascade. Vitamin K [ edit ] Vitamin K is an essential factor to a hepatic gamma-glutamyl carboxylase that adds a carboxyl group to glutamic acid residues on factors II, VII, IX and X, as well as Protein S , Protein C and Protein Z .

av S García García · 2007 · Citerat av 60 — The stability of the sodium and calcium forms of montmorillonite was studied at different NaCl and CaCl2 concentrations. The aggregation kinetics was

In this work, PIX-311 (a FeCl 3 coagulant produced by Kemira) and Al 2 (SO 4) 3 (ALG) were used as primary coagulants and CaCl 2 (produced by Water Treatment Coagulants Coagulant water treatment chemicals come in two main types – primary water treatment coagulants and coagulant aids. Primary coagulants neutralize the electrical charges of particles in the water which causes the particles to clump together. Chemically, coagulant water treatment chemicals are either metallic salts (such as alum) or polymers. Coagulation and flocculation occurs in successive steps, allowing particle collision and growth of floc. This is then followed by sedimentation (see Sedimentation Chapter). If coagulation is incomplete, flocculation step will be unsuccessful, and if flocculation is incomplete, sedimentation will be unsuccessful. COAGULATION Natural organic matter (NOM) is capable of interfering with Fe hydrolysis and influencing the size, morphology, and identity of Fe precipitates.

Calcium is essential for normal platelet adherence and for the subsequent spreading of platelets on the sub endothelium. Blood clotting process involves both intrinsic and extrinsic pathways. together with calcium. In order to kick off the INTRINSIC PATHWAY, some sort of negatively charged substance must be added. (in the living tissue, this is collagen exposed by cutting the vessel).

Calcium is also required at other points in the coagulation cascade. Vitamin K [ edit ] Vitamin K is an essential factor to a hepatic gamma-glutamyl carboxylase that adds a carboxyl group to glutamic acid residues on factors II, VII, IX and X, as well as Protein S , Protein C and Protein Z . The coagulation of the blood is initiated by the blood platelets.

This is important because PT and aPTT tests require the addition of calcium. Factors II, VII, IX and X require Calcium (factor IV) and Phospholipid (PL) for activation.

Addition of calcium chloride to milk has positive effects on cheese-making because it decreases coagulation time, creates firmer gels, and increases curd yield.
