What is an example of a coagulant?
What is an example of a coagulant?
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 are the common coagulant used?
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.
Which chemical is used as coagulant?
The main chemicals used for coagulation are aluminium sulphate (alum), polyaluminium chloride (also known as PAC or liquid alum), alum potash, and iron salts (ferric sulphate or ferric chloride).
Which coagulant is used for sewage treatment?
Aluminum and iron salts are the most commonly used inorganic coagulants in the wastewater treatment settings.
What makes a good coagulant?
A metal based coagulant will consume alkalinity, especially in a well buffered high pH water, which could compromise the softening process. The best coagulant is therefore a pre-hydrolysed species with a high basicity. PACl has been found to be very suitable for lime softening applications.
Which is the most commonly used coagulant in water treatment?
Alum or Aluminium sulphate is most commonly used as coagulants in water treatment.
What is the difference between coagulation and sedimentation?
is that sedimentation is the separation of a suspension of solid particles into a concentrated slurry and a supernatant liquid, either to concentrate the solid or to clarify the liquid while coagulation is the precipitation of suspended particles as they increase in size (by any of several physical or chemical …
What is inorganic coagulant?
Inorganic Coagulants As the coagulant is largely aluminium or iron based, it is particularly effective at treating raw water with low turbidity. Once added to water, inorganic coagulants form aluminium or iron precipitates, which will absorb impurities and serve to clean the water.
Which of the following is best coagulant?
∴ The best Coagulant for removing the color of water is Alum.
