What Are The Types Of Coagulation

Types of coagulation tests Complete blood count (CBC) Your doctor may order a complete blood count (CBC) as part of your routine physical. Factor V assay. This test measures Factor V, a substance involved in clotting. Fibrinogen level. Prothrombin time (PT or PT-INR) Platelet count. Thrombin time. Bleeding time.

What are the types of coagulants?

The aluminum coagulants include aluminum sulfate, aluminum chloride and sodium aluminate. The iron coagulants include ferric sulfate, ferrous sulfate, ferric chloride and ferric chloride sulfate. Other chemicals used as coagulants include hydrated lime and magnesium carbonate.

What is coagulation and its types?

COAGULATION:- The process of removal of suspended solids in water by the use of chemical agents is known as coagulation. Coagulation is carried out for the filtration and purification of water. CLASSIFICATION OF COAGULANTS 1) Primary coagulants, 2) Coagulant aids.

What is coagulant example?

Examples of primary coagulants are metallic salts, such as aluminum sulfate (referred to as alum), ferric sulfate, and ferric chloride. Cationic polymers may also be used as primary coagulants. 2. Chemicals commonly used for primary coagulants include aluminum or iron salts and organic polymers.

What is the most common used coagulation?

Aluminum sulfate (alum) is the most common coagulant used for water purification. Other chemicals, such as ferric sulfate or sodium aluminate, may also be used. Coagulation is usually accomplished in two stages: rapid mixing and slow mixing.

What are the common coagulants used?

Chemical Coagulants Used In Water Treatment Aluminum Sulfate (Alum) – One of the most commonly used water treatment chemicals in the world. Aluminum Chloride – A second choice to Alum as it is more expensive, hazardous and corrosive. Polyaluminum Chloride (PAC) & Aluminum Chlorohydrate (ACH).

What is the coagulation process?

Coagulation, in physiology, the process by which a blood clot is formed. The formation of a clot is often referred to as secondary hemostasis, because it forms the second stage in the process of arresting the loss of blood from a ruptured vessel.

What are the 4 steps of coagulation?

1) Constriction of the blood vessel. 2) Formation of a temporary “platelet plug.” 3) Activation of the coagulation cascade. 4) Formation of “fibrin plug” or the final clot.

What is purpose of coagulation?

Coagulation is a process used to neutralise charges and form a gelatinous mass to trap (or bridge) particles thus forming a mass large enough to settle or be trapped in the filter.

Is coagulation good or bad?

Blood clotting is a natural process; without it, you would be at risk of bleeding to death from a simple cut. Blood clots inside the cardiovascular system are not always so welcome. A clot in the coronary arteries near the heart can cause a heart attack; one in the brain or the arteries serving it, a stroke.

What is coagulant mean?

A coagulant is a compound or agent which is added to a vessel to help thicken something. Adding a coagulant such as aluminum sulfate to water permits particles to come together and results in the formation of a flocculent mass. A coagulant is a compound or agent which is added to a vessel to help thicken something.

Is na2so4 a coagulant?

Sodium sulfate is a well-known coagulant for PVA, and it is used in the coagulation bath of PVA before wet spinning of vinylon fibers.

Why alum is used as coagulant?

When alum is added to water, it reacts with the water and results in positively charged ions. Coagulation removes colloids and suspended solids from the water. These particles have a negative charge, so the positively charged coagulant chemicals neutralize them during coagulation.

Is coagulation reversible?

Coagulation is irreversible, the proteins cannot be turned back into their liquid form.

What are the factors affecting coagulation?

Factors. Coagulation is affected by the type of coagulant used, its dose and mass; pH and initial turbidity of the water that is being treated; and properties of the pollutants present. The effectiveness of the coagulation process is also affected by pretreatments like oxidation.

What are natural coagulants?

BEWAT natural products are a very specific range focused on treating wastewater. They are mainly composed of polymers of natural origin extracted from plants, algae or animals. Among these are polysaccharides and water soluble substances that act as coagulation and / or flocculation agents.

What is the difference between coagulant and flocculant?

Flocculants differ from coagulants in that they are often polymers, whereas coagulants are typically salts. Generally speaking, anionic flocculants are used to catch mineral particles while cationic flocculants can capture organic particles.

What is the normal coagulation process?

Blood coagulation is a process that changes circulating substances within the blood into an insoluble gel. The gel plugs leaks in blood vessels and stops the loss of blood. The process requires coagulation factors, calcium and phospholipids. The coagulation factors (proteins) are manufactured by the liver.

What is egg coagulation?

Coagulation indicates a change from a fluid to a solid or semisolid (gel) state. The success of many cooked foods depends on the coagulative properties of proteins, particularly the irreversible coagulative properties of egg proteins. Egg proteins denature and coagulate over a wide temperature range.

What are the three phases of coagulation?

The three phases of coagulation occur on different cell surfaces: Initiation on the tissue factor-bearing cell; Amplification on the platelet as it becomes activated; and Propagation on the activated platelet surface. Based on our work and that of many other workers, we have developed a model of coagulation in vivo.

What are the two coagulation pathways?

The clotting cascade occurs through two separate pathways that interact, the intrinsic and the extrinsic pathway. The extrinsic pathway is activated by external trauma that causes blood to escape from the vascular system. This pathway is quicker than the intrinsic pathway.

What is blood clotting called?

A blood clot is also called a thrombus. The clot may stay in one spot (called thrombosis) or move through the body (called embolism or thromboembolism). The clots that move are especially dangerous.

What is the common coagulation pathway?

The common pathway consists of factors I, II, V, VIII, X. The factors circulate through the bloodstream as zymogens and are activated into serine proteases. These serine proteases act as a catalyst to cleave the next zymogen into more serine proteases and ultimately activate fibrinogen.

What does coagulation remove?

Coagulation is the chemical water treatment process used to remove solids from water, by manipulating electrostatic charges of particles suspended in water. This process introduces small, highly charged molecules into water to destabilize the charges on particles, colloids, or oily materials in suspension.

What are the 5 stages of water treatment?

These include: (1) Collection ; (2) Screening and Straining ; (3) Chemical Addition ; (4) Coagulation and Flocculation ; (5) Sedimentation and Clarification ; (6) Filtration ; (7) Disinfection ; (8) Storage ; (9) and finally Distribution. Let’s examine these steps in more detail.

What are the characteristics of good coagulant?

There are three key properties of a coagulant : Trivalent cation : As indicated in the last section, the colloids most commonly found in natural waters are negatively charged, hence a cation is required to neutralize the charge. Nontoxic : This requirement is obvious for the production of a safe water.
