This document summarizes a civil engineering project analyzing and treating groundwater pollution around a dyeing industry. The objectives are to analyze water sample quality, map pollutant contamination levels, and treat samples using suitable methods. Water samples were collected from 5 locations near the dyeing industry and tested for various physicochemical parameters. The samples will be treated using appropriate treatment methods based on the test results. The project aims to study water pollution from dyeing industries and find treatment solutions to clean the contaminated groundwater.

Around Dyeing Industry

2. OBJECTIVE
⮚ To analysis the quality of water sample.
⮚ To map the pollutant contamination level.
⮚ To treat the sample using suitable treatment
methods.

3. INTRODUCTION
• Water pollution (or aquatic pollution) is the
contamination of water bodies, usually as a result of
human activities, so that it negatively affects its uses.
• Water bodies include lakes, rivers, oceans, aquifers,
reservoirs and groundwater. Water pollution results
when contaminants are introduced into these water
bodies.
• Water pollution can be attributed to one of four sources:
sewage discharges, industrial activities, agricultural
activities, and urban runoff including stormwater.

4. WATER POLLUTION IN DYEING INDUSTRY
• Industrial dye degradation is any of a number of
processed by which dyes are broken down, ideally
into innocuous products. Many dyes, specifically in
the textile industry such as methylene blue or
methyl red, are released into ecosystems through
water waste. Many of these dyes can be
carcinogenic. In paper recycling dyes can be
removed from fibres during a deinking stage prior
to degradation.

METHODOLOGY

9. Collection of water sample around Dyeing industry.
Testing the basic water quality parameters (pH,EC, TDS,
COD, BOD, Heavy metals etc..)
Mapping of contaminant around the dyeing industry.
WORK SEQUENCE – PHASE I

10. Treatment of Ground water by suitable
methods based on water quality parameter
results.
WORK SEQUENCE – PHASE II

11. Five representative groundwater samples
were collected in the dyeing industrial areas of
Coimbatore City during August 2022. The
locations of the groundwater sample sites were
listed in BelowTable and Fig.
GROUNDWATER SAMPLES COLLECTING

12. The samples were analyzed for the parameters pH,
Alkalinity, Hardness, Fluoride, Chlorides, Ammonia,
Nitrate, Iron, Residual Chlorine and Total Dissolved
solids were tested in the laboratory as per the standard
test procedure and the results were compared with IS:
10500 – 2012 (DRINKING WATER – SPECIFICATION
SECOND REVISION).
GROUNDWATER SAMPLES COLLECTING

13. GROUNDWATER SAMPLES COLLECTING
All the groundwater samples were found to
be colorless and odourless.
The temperature of the groundwater
samples was found about 30 C.

15. Physico - Chemical Parameters
pH:
 pH is the logarithmic scale used to specify the acidity or basicity of water.
 It ranges from 0 – 14. When pH value is lower than 7 then the water is
acidic and pH value exceeds 7 then the water is basic.
 Water with pH 7 is said to be neutral.

16. Physico - Chemical Parameters
Alkalinity (AT):
 Alkalinity is the measure of ability of water to neutralize acid. It
measures the level of bi carbonates, carbonates and hydroxides in water.
 It is expressed as “ppm of calcium carbonate (CaCO3)”.

17. Physico - Chemical Parameters
Hardness (H):
 Hardness can be classified into temporary hardness due to the presence of
carbonate & bicarbonates of calcium & magnesium and permanent hardness due
to the presence of sulphate & chlorides of calcium & magnesium.
 The hardness of portable water has been classified in terms of CaCO3
concentrations : 60 – 120mg/l – Soft ; 120 – 180mg/l – Hard ; more than 180mg/l
– Terribly hard.

18. Physico - Chemical Parameters
Fluoride (F-):
 It is an inorganic, monatomic anion whose salts are white or
colorless. Addition of fluoride in the water is to reduce tooth decay.
Higher consumption may leads to fluorosis.

19. Physico - Chemical Parameters
Ammonia (NH3):
 Ammonia is a colorless gas. It can be present in water in 2 forms either
ammonium hydroxide (NH3) or as ammonium ion (NH4).

20. Physico - Chemical Parameters
Nitrate (NO3
-):
 Nitrites are salts of nitrous acid, which can be naturally present in ground
water.
 It also occurred artificially from fertilizers, sewage and mineral deposits.

21. Physico - Chemical Parameters
Iron (Fe):
 Iron can be present in water in 2 forms either soluble ferrous iron or the
insoluble ferric iron. Iron overload may lead to liver, heart damages.

22. Physico - Chemical Parameters
Chlorides (Cl-):
 Chlorides are present in water with varying concentration.
 When the mineral content in water is increased then chloride content will
automatically increases.

23. Physico - Chemical Parameters
Chlorine (Cl):
 Adding chlorine or chlorine compounds such as sodium hydro
chlorine in water is to kill certain bacteria and other microbes.

24. Physico - Chemical Parameters
Total Dissolved solids (TDS):
 It is a measure of any metals, minerals, salts dissolved in water.
 It is expressed in ppm or mg/l.

25. Physico chemical parameter limits
Parameters Limits (mg/l) except pH
