9. Focus/Goal/Aim: To understand the working procedure of water treatment plant for purification of water and to understand the supply of water to various parts of the city.
10. Objective: Students should understand the treatment process practically as it is well said that we can remember the things we see visually that what we read.
11. Methodology: After reaching at the location, Mr. Pradeep Wankhade along with his co-staff explained the step by step procedure of treatment of water. He included each and every point from where the water enters the plant and where it is supplied after purification.
Water treatment process involves stages such as aeration, alum dosing, flocculation, water settling and sedimentation tank, filtration, chlorination, service reservoir and distribution pipes.
Aeration: To increase the oxygen percentage, water is first subjected to aeration through fountains or cascades.
Alum Dosing: Alum (Al2SO4) is added to water flow and this mixture is churned in flash mixer. This causes the suspended particles to form floccus and mixture is passed through flocculator.
Floculation: Due to chemical reaction of Alum, there is formation of floccus. Some of this floccus settles down at the base of flocculator from where it is drained off.
Settling and Sedimentation Tank: Water from flocculator flows into circular settling and sedimentation tank where it is drained for 3 hours. Due to this excessive floccus and suspended particles settle down in the base in the form of sediment which is drained off.
Filtration: Filtration tanks are filled with layers of fine sand, coarse sand and pebbles. The water percolated through these layers and filtration of water takes place whereby whatever floccus and suspended impurities might have escaped from earlier process is trapped by sand and pebble layers and what flows down towards the bottom of tank is the filtered clean water.
Chlorination: Chlorine is mixed into this clean water in a required dose to kill pathogenic bacteria.
Service Reservoir: There are service reservoirs which store the treated water for supplying it to various regions.
This is the process followed for treatment of waste water.
