“ANALYSIS OF INDUSTRIAL

WASTEWATER”



INTRODUCTION

Water analysis- water analysis is done to determine thephysical and chemical characteristics of water sample.

Physical Chemical

1. Turbidity 1. pH

2. Color 2. Alkalinity

3. Odour 3. Chloride content

4. Total dissolvedsolids(TDS)

4. Acidity

5. Temperature 5. Dissolved solids(D.O.)

6. Hardness



WASTEWATER

Industrial Wastewater is broadly

stated to be any water carrying

material/wastes that result from abusiness activity or from the

development/recovery of a natural

resource.



IS PARAMETERS

S.No. Characteristics Permissible Limits

1. Color(Hazen) 5-15

2. Odour Agreeable

3. Taste Agreeable

4. Turbidity(NTU) 1-5

5. Dissolved solids(mg/l) 500-2000

6. pH value 6.5-8.5

7. Total hardness(mg/l) 200-600

8. Chloride content(mg/l) 250-1000

9. Total alkalinity(mg/l) 200-600



COLLECTION OF WATER

SAMPLE

We have obtained the samples from

following industries of Rajnandgaon-

Sample (1)- Kamal solvent ,Somni.

Sample (2)- Raja Ram madeproducts(Glucose factory),

Bhotipar.



METHADOLOGY

We have performed two methods for

analyzing wastewater-

1) Titration method- Titration is common laboratorymethod of chemical analysis that can be used to

determine the concentration of an unidentified

analyte.

2) Electronic method(water analyzer kit)- It is a

direct method by which impurities can be

determined by electronic instrument.



TESTS PERFORMED

1. Hardness-

The presence in water of dissolved calcium

or magnesium ions, which form a scum withsoap and prevent the formation of a lather.

The main cause of hard water is dissolved

calcium & Magnesium bi-carbonate,which isformed in limestone or chalk regions by theaction of dissolved carbon dioxide oncalcium carbonate.



Hardness of samples

Sample(1) Sample(2)

610 mg/l NIL

Table (1)- The hardness values of sample (1) and sample (2)

are as follows-



2. Alkalinity-

Alkalinity of natural water may be attributed

to the presence of salts weak acids as

bicarbonates, phosphates, silicates and

borates which includes buffer capacity and

resists the lowering of pH.

The value of pH above 7 indicates thatthe alkalinity is present in the sample



Alkalinity of samples

Sample(1) Sample(2)

384.6 mg/l NIL

Table (2)- The Alkalinity of sample (1) and sample (2) are as

follows-



3. Acidity-

The acidity due to presence of free minerals

acids, organic acids & free CO2.

Acidity levels in wastewater indicate its

corrosive properties and can take a leading

role in regulating biological processes as

well as in chemical reactions (such aschemical coagulation and flocculation).



Acidity of samples

Sample(1) Sample(2)

111.08 mg/l 5859.47 mg/l

Table (3)- The Acidity of sample (1) and sample (2) are as

follows-



4. Chloride content-

The chlorides are estimated by titrating

the water sample with standard solution of

silver nitrate using potassium chromate asindicator



Chloride content of samples

Sample(1) Sample(2)

Table (4)- The Chloride content of sample (1) and sample (2)

are as follows-



5.Turbidity-

Turbidity is the cloudiness or haziness of a

fluid caused by individual particles

(suspended solids) that are generally

invisible to the naked eye, similar tosmoke in air.

The measurement of turbidity is a key test

of water quality.



Turbidity of samples

Sample(1) Sample(2)

1 NTU 159 NTU

Table (5)- The Turbidity of sample (1) and sample (2) are as

follows-

* NTU- Nepthlometer turbidity unit



6. Conductivity-

Conductivity is a measurement of the ability

of an aqueous solution to carry an electrical

current.

Conductivity is a measurement used to

determine a number of applications related

to water quality.



Conductivity of samples

Sample(1) Sample(2)

0.745 mho 1.00 mho

Table (6)- The Conductivity of sample (1) and sample (2) are

as follows-



7. Temperature-

The temperature of waste water is slightly

higher then ordinary water.

The temperature has an effect on thebiological activity of bacteria presents in

waste water..

The average temperature of waste water is

20-25ºC which is ideal temperature for

biological activity.



Temperature of samples

Sample(1) Sample(2)

28.3 ºC 29.1ºC

Table (7)- The Temperature of sample (1) and sample (2) are

as follows-



8. pH value-

pH is a measure of acidity or alkalinity. The

water quality regulations specify that the pH

of tap water should be between 6.5 and 9.5.

Water leaving our treatment works typically

has a pH between 7 and 8, but this can

change as it passes through the network of

reservoirs and water mains.



pH value of samples

Sample(1) Sample(2)

7.13 4.73

Table (8)- The pH value of sample (1) and sample (2) are as

follows-



9. Total Dissolve Solids(TDS)-

Total Dissolved Solids (TDS) are the total

amount of mobile charged ions, including

minerals, salts or metals dissolved in a

given volume of water.

TDS is directly related to the purity of water

and the quality of water purification systems

and affects everything that consumes, lives

in, or uses water, whether organic or

inorganic, whether for better or for worse.



TDS of samples

Sample(1) Sample(2)

74mg/l 670mg/l

Table (9)- The TDS of sample (1) and sample (2) are as

follows-



10. Dissolve Oxygen- (DO)

Dissolved oxygen analysis measures the

amount of gaseous oxygen (O2) dissolved

in an aqueous solution.

Its solubility increases with the pressure

and decreases with the temperature.



DO of samples

Sample(1) Sample(2)

1.7mg/l 110.1mg/l

Table (10)- The DO of sample (1) and sample (2) are as

follows-

Conclusion-

As per our analysis we found that the

industrial wastewater sample 1 & 2 can not

be used for drinking purpose as well as

domestic purpose.
