The objective of the paper is to design Grit Chamber which is efficient for removal of Grits. Separation may be applicable for the different type of methods which may include discrete settling, flocculants settling, compressed settling, accelerated gravity settling. The removal of grit is being done by the process of sedimentation which is being done in the primary phase of water and wastewater treatment. The design of grit chamber is being done on the basis of various parameters which may be in due consideration depending on the influent characteristics, which may lead to design consideration for different treatment plants. Talking of the treatment of wastewater or water, the first phase of treatment is the separation of physical ingredient which are carried away by different means in water and wastewater. Separation of grit is important as going into the system may affect the operation of the wastewater treatment system as it may lead to wear and tear of the Mechanical Equipments. Settling velocity plays the vital role in the design of Grit Chamber which is explained in detail in this paper, as it affects the settling of the particles and also horizontal velocity is made into consideration of the design of Grit Chamber.


Discrete Settling, Flocculent Settling, Compressed Settling, Settling Velocity, Horizontal Velocity.
