We, 5th sem UVCE CIVIL ENGINEERING STUDENTS went to technical
trip to T.K.HALLI WATER TREATMENT PLANT on 16th November 2013.
There I took few informative pics. Hope you all like this
blog post, especially civil engineering students as it is a very informative
post.
1.
INTAKE:
The intakes or intake works are the devices or structures
installed for the purpose of drawing water from source like river, canal, lake
or a reservoir.
2.
CASCADE AERATORS:
Water is made to fall in the form of thin sheet, over a series
of steps. During the fall, water mixes thoroughly with atmospheric air and get
aerated, absorb oxygen for the reduction of taste, odor etc. 
Suspended particles in water are permitted to settle only by
gravity.
The process of adding certain chemicals for accelerating
sedimentation and the effective removal of very fine and colloidal particles is
known as coagulation. Alum is the most widely used coagulant in water treatment
plants.
4.
FILTRATION:
The process of passing the water through the beds of
granular materials (Filters) is known as FILTRATION. Filtration may help in
removing color, odor, turbidity and pathogenic bacteria from water.
Example: Rapid sand filters
BACK WASHING:
When sand becomes dirty, as it is indicated by the excessive
loss of head, the filter must be cleaned and washed by forced upward movement
of wash water and compressed air.
5.
DISINFECTION:
The process of killing disease causing micro organisms
(Pathogens) present in water so as to make it safe for human consumption.
Application of chlorine gas or its compounds like bleaching
powder, liquid chlorine for disinfecting water is known as chlorination.
Then we could get the treated water after these processes
but the thing is how the waste water from these processes would maintain??? Hope
I would have done another post in the future....
At last Thanks to our H.O.D Shantveerangouda , Ph.D Scholors
D.Prathibha and Idris . Special thanks to my sisters Shilpa Patil, Mamata
Patil and Rashmi Patil, who always supports me....
