What is non flocculated suspension
The suspension are said to be flocculated ,when the individual particles are in contact with each other and form a network like structure .Whereas in case of non-flocculated suspensions,the individual particles exists as a separate entity. In Non-flocculated suspensions The rate of sedimentation is slow.
What does flocculation mean
The process by which individual particles of clay aggregate into clotlike masses or precipitate into small lumps. Flocculation occurs as a result of a chemical reaction between the clay particles and another substance, usually salt water.
What is stability of suspension
STABILITY OF SUSPENSION. It is important to understand that suspensions are kinetically stable, but thermodynamically unstable, system. Physical stability is defined as the condition in which the particles remain uniformly distributed throughout the dispersion without any signs of sedimentation.
What is a flocculating agent and how does it work
Flocculants, or flocculating agents (also known as flocking agents), are chemicals that promote flocculation by causing colloids and other suspended particles in liquids to aggregate, forming a floc. Flocculants are used in water treatment processes to improve the sedimentation or filterability of small particles.
Which suspension is better Flocculated or Deflocculated
The main difference between flocculated and deflocculated suspension is that the rate of sedimentation in a flocculated suspension is rapid whereas the rate of sedimentation in a deflocculated suspension is slow.
What is suspension in pharma
A pharmaceutical suspension is a coarse dispersion of insoluble solid particles in a liquid medium. In addition, when compared to solution dosage forms, relatively higher concentration of drugs can be incorporated into suspension products.
Why is flocculation important
Coagulation and flocculation are important processes in water treatment with coagulation to destabilize particles through chemical reaction between coagulant and colloids, and flocculation to transport the destabilized particles that will cause collisions with floc.
Why is alum added to the water
Aluminium Sulfate, Shortly known as Alum, when added to raw water reacts with the bicarbonate alkalinities present in water and forms a gelatinous precipitate. This floc attracts other fine particles and suspended material in raw water, and settles down at the bottom of the container.
What is flocculation test
Medical Definition of flocculation test
: any of various serological tests (as the Mazzini test for syphilis) in which a positive result depends on the combination of an antigen and antibody to produce a flocculent precipitate.

Why suspension is thermodynamically unstable
All suspensions, including coarse emulsions, are inherently thermodynamically unstable. They will, through random motion of the particles over time, aggregate because of the natural and dominant tendency to decrease the large speciﬁc surface area and excess surface energy.
What affects emulsion stability
Temperature can affect emulsion stability significantly. Temperature affects the physical properties of oil, water, interfacial films, and surfactant solubilities in the oil and water phases. These, in turn, affect the stability of the emulsion. This decrease is mainly because of a decrease in the oil viscosity.
How does flocculation occur
Flocculation is when microscopic particles bind together to form larger particles in liquids. It occurs naturally or artificially in water as well as other solutions. Flocculation is used in applications such as water purification, sewage treatment, cheese production, and brewing.
What chemical is used for flocculation
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 are coagulant chemicals used for
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).
What is the difference between suspension and emulsion
Emulsions are an example of colloids composed of tiny particles suspended in another immiscible (unmixable) material. An emulsion is a suspension of two liquids that usually do not mix together. For example if we mix oil and water a suspension will form that over time separates.
What is dry suspension
Dry suspension is commercial dry mixtures that require addition of water at the time of dispensing. The major consequence of the bitter taste is to restrict greatly the further development of oral preparations and clinical applications of these drugs. Eudragit L100 is used as taste masking agent.
What is oral suspension
In technical terms, an oral suspension is a liquid medium in which coarse, insoluble drug particles have been dispersed. Oral suspensions make the administration of insoluble drugs in liquid format feasible. Administering Oral Suspension Medicines.
