T.K HALLI WATER TREATMENT PLANT:VISIT!!! (UVCE)

We, 5^th sem UVCE CIVIL ENGINEERING STUDENTS went to technical trip to T.K.HALLI WATER TREATMENT PLANT on 16^th 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. 

3.       PLAIN SEDIMENTATION:

Suspended particles in water are permitted to settle only by gravity. 

SEDIMENTATION WITH COAGULATION

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.

FLASH MIXTURE AND FORMATION OF SLUDGE:

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....
