Difference Between Coagulation and Flocculation Ppt

Material for this article was largely taken from reference 1. If coagulation is incomplete flocculation step will be unsuccessful and if flocculation is incomplete.

First process in drinking water treatment coagulation is to destabilize the particles and allow them the potential to collide and stick together.

. During coagulation the coagulant alum are added to destabilize the surface charge of particles in order to promote the formation of microflocs during the collision. Coagulation means to curdle. Coagulation and Flocculation in Water Treatment is the property of its rightful owner.

On the other hand flocculation means to form flocs. Aggregation based on reducing inter-particle repulsion forces is known as coagulation and the aggregates are called coagula. MurtyDepartment of Civil Engineering IIT MadrasFor.

Furthermore denaturation is the first step of coagulation while the two steps of coagulation are denaturation and precipitation. If coagulation is induced by a polymer-bridging action the process is called flocculation and the aggregates are called flocs. Removal of Precipitates Coagulation Rapid Chemical Mix Destabilization of Suspended Particles Flocculation Slow Mix Particle Collision and Growth.

These particles form clumps with the help of a coagulant. Flocculation allows forming floc in quiescence slow. FLOCCULATION Process where colloids come out of suspension in the form of floc or flake Due to.

There are four main mechanisms for coagulation. Coagulation is the neutralization of the electronic charge on suspended particles. This is then followed by sedimentation see Sedimentation Chapter.

Coagulation Flocculation and Sedimentation Dr. Particles in water such as clay usually have a negative charge. During Flocculation the solution is mixed gently providing time and energy so the clumps will gather together and form larger clumps.

Theres a difference between coagulation and flocculation and the mechanism that causes particles to aggregate and come together so that they can be filtered or settled. Coagulation is the destabilization of colloids by addition of chemicals that neutralize the negative charges The chemicals are known as coagulants usually higher valence cationic salts Al3 Fe3 etc Coagulation is essentially a chemical process - - - - - - - - - - - - - - - - - - - - - - - - - - - - water treatment What is Flocculation. After coagulation the destabilized particles can collide aggregate so flocs can be formed.

Clump together and settle out of the water unless proper coagulation and flocculation is used. Coagulation and flocculation occurs in successive steps allowing particle collision and growth of floc. Zeta potential is the charge at the boundary of the colloidal turbidity particle and the surrounding water.

Coagulation is a chemical process and flocculation is a physical process In coagulation the process involves the utilization of a coagulant that has the ability to destabilize the charged particles which are not settleable whilst flocculation involves a similar destabilization process that is achieved through physical mixing and by adding organic polymers. This step is called flocculation. Coagulation and flocculation are an essential part of drinking water treatment as well as wastewater treatment.

Lectures Series on Water Waste Water Engineering by Prof CVenkobachar Prof. There are three steps. Velocity around 1 ftsec in the flocculation basins should be maintained.

Difference between Coagulation and Flocculation. It basically refers to a chemical process in which the destabilization of non-settleable particles takes place. Coagulation also known as.

Double layer compression adsorption and charge neutralization sweep flocculation and inter-particle bridging. Coagulation means to curdle. 6252020 4 Coagulation and Flocculation 8 Coagulation-Double-layer compression charge neutralization-Enmeshment sweep coagulationClay suspension Ferric chloride 40-120 ppm Flocculation-Polymer Bridging Clay suspension Ferric chloride Polymer 1 ppm.

Difference between denaturation and coagulation. The main difference between denaturation and coagulation is that denaturation is the process of losing the native state of proteins and nucleic acids whereas coagulation is the change in the structure of proteins precipitating them. On the other hand flocculation means to form flocs.

Dirt particles in the water then stick together or coagulate and continue to stick together until heavy particles. When aggregation is achieved as a result of the action of an. 1the addition of a clarifying agent 2spontaneously Occur in successive steps intended to overcome the forces Stabilizes the suspended particles allowing particle collision and growth of floc.

The PowerPoint PPT presentation. The higher the charge the more is the repulsion between the turbidity particles less the. Flocculation Process The flocculation process takes treated water from the coagulation stage and mixes it slowly to increase the collision rate between suspended microfloc particles.

In flocculation one can make a distinction between perikinetic and. In contrast in flocculation the de-stabilization is brought about by physical techniques such as mixing of the solution and also sometimes by the addition of polymers. Denaturation is the changing of a proteins shape due to external stress.

This is the key difference between coagulation and. Do you have PowerPoint slides to share. Sweep flocculation is the primary.

Flocculation takes the coagulation process a step further by gently agitating the microfloc-containing water at varying speeds to encourage more particle adhesion. Types of Water Treatment Processes Coagulation or Flocculation In this process liquid aluminum sulphate or polymer is added to water. Coagulation involves the use of a coagulant which has the potential to de-stabilize the previously stabilized charged particles in the suspension.

It basically refers to a chemical process in which the destabilization of non-settleable particles takes place. Coagulation and flocculation are essential processes in various disciplines. These particles form clumps with the help of a coagulant.

The process of agglomeration of the destabilized particles to such a size that separation by sedimentation and filtration is possible. This article provides an overview of the processes and looks at the latest thinking. The key difference between coagulation and flocculation in water treatment is that the coagulation is a chemical process while flocculation is a physical process.

CoagulationFlocculationPhysical Removal Designed to remove Microorganisms Toxic compounds that are sorbed to particles NOM because it is a precursor of DBPs Designed to make the water more palatable Coagulant properties Non-toxic and relatively inexpensive Insoluble in neutral pH range - do not want high concentrations of metals left in treated water.
