In designing flocculation tanks, several factors should be considered. They are :
i. Flexibility which should include alternative flocculant aid application and the capabiluty to vary velocity gradient.
ii. To minimise short circuiting, a minimum of three compartments in series should be provided.
iii. Type of coagulants used
iv. Provosion of space for furture increase in the number of flocculation tanks when upgrading the treatment plant
v. A minimum of two tanks to be built in any treatment plant

What is added to water to cause flocculation?
Electrolytes trap suspended particles by causing them to clump together and fall to the bottom of the tank as sediment. These clumps are called floc, and the process is called flocculation.
What is flocculation?
Flocculation is one step in the water and wastewater treatment process. In a flocculation tank, the water is stirred or otherwise moved around so that the particles move around, bump into other particles, and stick to one another. Eventually the small and difficult to remove particles in the water form large clumps which can then be easily removed. Chemicals (most commonly "alum") are often added to the water going into a flocculation tank to help aid particle formation.

What is degree of flocculation?
Degree of flocculation is mainly related to ability of flocculating agent too form "flocs" in suspension. Higher the degree of flocculation, better the agent.
What does identify criteria mean in engineering?
constraint is a limit to design process and criteria is want
What does functional criteria mean in design?
Explaining what your design must do to be considered successful.
What is a 5 letter word for design criteria?
Brief.
What is flocculation and flotation?
Flocculation means lysing a cell or bursting a cell to get its composition.flotation means culturing the cells to increase its quantity.
What is the criteria by which successful graphic design is judged?
Passion and authenticity.
What happens in flocculation?
The process of flocculation is when particles in suspension precipitate out. In water purification plants, for example, a chemical (usually Ferric Chloride) is added to the water in large pools. The chemical makes particles that are suspended in the water adhere to each other, and as they get larger they drop to the bottom of the tank. The water that is then drained out is much cleaner now that the particles have been removed.
What are the four criteria on which the evaluation of art is based?
Craftmenship, design, aesthetic, and properties.
How does flocculation efficiency depend on charge?
Flocculation efficiency increases with increasing electrical charge on the flocculating species. For example, Al+3 > Ca+2, > Na+.
