INDUSTRIAL SITE VISIT REPORT. 01-12-2018 /
REPORT ON: “Industrial site visit at IDCO water treatment plant, Khorda, Odisha.
PREPARED BY: Mrs. Sushree Manisha Samanta, Assistant Professor (Civil Engineering Dept.)
BACKGROUND:
- Water treatmentis any process that makeswatermore acceptable for a specific end-use.
- The end use may bedrinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment.
- Water treatment removescontaminantsand undesirable components, or reduces their concentration so that the water becomes fit for its desired end-use.
- Students should understand and apply their theoretical knowledge by visualising the practical view of industries.
- Visiting the IDCO water treatment plant is a great way to learn how the plant works. How they are treating raw water as per their requirement.
PLACE OF TOUR:
(IDCO water treatment plant, Khorda, Odisha)
DATE , VENUE & TIME:
Date of visit:16.01.2017
Venue: IDCO water treatment plant, Khorda, Odisha
TIME: 10.00 AM to 1.00 PM
PARTICIPANTS:
Mrs. Sushree Manisha Samanta, Shri Santosh Kumar Swain and 42NOs of 08th semester civil engineering students participated on the training program.
INTRODUCTION:
Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids and gasses from contaminated water. The goal is to produce water for a specific purpose.
OBSERVATION:
•Student life is a great experience of time to make the theoretical experience to practical one and to make the study, we went for a visit to IDCO water works plant; which supplies water to the industries in industrial estate KHURDHA.
•In IDCO water work, the clear water reservoirs is of capacity “500x2=1000cum”. This is followed by the IS09001 and 14001 corporation.
•The water to the IDCO water work is coming from DAYA river 12KM away from the plant.
•The water is directly transport to the plant from river. And tested the quality of the water and then apply the required treatment.
•In IDCO water works, there is alum is added to purify the impurities of the water and the quantity of alum may decided by the tests taken for the raw water.
•After taking required treatment for the row water as per the tests, the water may become suitable for supply. Then the IDCO water work supplies water to the industries.
STEPS FOR THE TREATMENT OF WATER:
•DISINFECTION:Chlorine is added to the water for disinfection.
•COAGULATION & FLOCCULATION: Alum is added in proportion to the river turbidity to form the particles created from the suspended materials in the water.
•SEDIMENTATION:The water travels through sedimentation basins where the heavier material settles. Coagulation and flocculation remove turbidity as well as metals including arsenic.
•FILTRATION:following sedimentation; the water travels through an extensive filtration process that removes sediment & other suspended material.
•CORROSION CONTROL: At the end of the treatment process, PH is adjusted with caustic soda (NaOH) to reduce corrosion in plumbing system.
•FLOCCULATION: The process by which fine particles are caused to clump together into flock. The flock can then settle to the bottom and be filtered from the water.
•TURBIDITY:Turbidity is a measure of the cloudiness of the water. The typical cause of turbidity is tiny particles of sediment in the water.

CONCLUSION:
•As of 2006,waterborne diseasesare estimated to have caused 1.8 million deaths each year. These deaths are attributable to inadequate publicsanitationsystems and in these cases, propersewerage that must be installed.
•Appropriate technologyoptions in water treatment include both community-scale and household-scalepoint-of-use(POU) designs. Such designs may employsolar water disinfectionmethods, using solar irradiation to inactivate harmful waterborne microorganisms directly, mainly by the UV-A component of the solar spectrum, or indirectly through the presence of an oxidephotocatalyst, typically supportedTiO2in itsanataseorrutilephases.Despite progress inSODIStechnology, military surplus water treatment units like theERDLatorare still frequently used in developing countries. Newer military styleReverse Osmosis Water Purification Units(ROWPU) are portable, self-contained water treatment plants are becoming more available for public use.
