This document summarizes a seminar presentation on reusing textile sludge in concrete. The textile industry produces large amounts of sludge as a byproduct of wastewater treatment. Currently, most sludge is disposed of in landfills. The objectives of the project are to reuse the sludge in concrete to reduce environmental pollution and use resources more efficiently. Testing shows the sludge can be used to replace up to 32% of sand in concrete with little reduction in compressive strength. Using sludge in concrete provides advantages like reducing land and groundwater pollution compared to disposal. Further work could explore using sludge ash in concrete after burning the organic matter.

Reuse of textile sludge in concret
PRESENTED BY-MOHAMMAD MUJTABA

2. Content
 Objectives of Project
 Introduction
 Characterization of sludge
 Process
 Scope of Work
.

3. Introduction
 Textile industry is one of the oldest and second
largest industries in India.
 Maharashtra state also has number of textile
industries in cities like JaLgoan & Faizpur.
 Jargon have Raymond industries and many
small scale & large scale textile units located in
and around jalgaon.
 During manufacturing of clothes and other
textile products, huge quantity of water is
required for various operations such as dyeing,
washing etc.
.

4.  Smaller units can not afford treatment
plant, therefore waste being disposed in
nallah without treatment.
 No further biological treatment can be
given so it is disposal in Landfills as a
ultimate disposal option.
 Textile waste water can be treated by
Effluent Treatment Process(ETP).
.

5. Objectives of Project
 To reuse textile mill sludge in Concrete, So that to
increase bulk usage of sludge in concrete by
protecting the environment.
 The main reason behind the reuse of sludge is
Save the soil pollution and Save the Planet for our
future generation.
 Growing need to find suitable alternatives for sludge
management.

8. Characterization of sludge:
Physical and Chemical parameters of Textile Mill
Sludge
Sr. No. Parameter Value
1 Specific Gravity 1.2-1.5
2 Dry density 1200-1500 kg/m3
3 pH (1:5 sludge suspension) 6.46
4 EC (25oC) 11.93 mS
.

9. Textile ETP Sludge
PROCESS
 COLLECTION FROM EFFILUENT
TRETMENT PLANT
 SLUDGE IS DRIED
 SIEVED TO REMOVE DUST
 MIXING PROPORTION IS 4% ,8%
,12%
.

10.  Then the sludge was mixed along with
the cement concrete and mortar
 The sludge was found to have very
high concentration of pollutants like
sulfate, chloride, color etc.,
.

11. Test to be performed
 Workability test
 1.Slump test
 2. Compacting factor test
 Compressive test
 Soundness test
 Setting time
N.K.O.C.E.T, SOLAPUR.

12. Advantages
 No leaching
 Low cost housing
 Land pollution can be reduced
 Minimum Land acquisition
 No effect on human health coz sludge having
chemical nature.
 Ground water pollution will be minimum
 Sludge can be available in free of cost.
 The Sludge Use in Brick Manufacturing
.

13. DISADVANTAGES
 The use of textile ETP sludge in
reinforced cement concrete will
corrode the reinforcements due to its
corrosive properties
 There is a little transportation problem.
 Unburnt Textile Waste is not suitable
for concrete production
N.K.O.C.E.T, SOLAPUR.

14. Future Scope of Work
 Clothing & textile recycling reduces
the need for landfill space.
 Clothing & textile recycling reduces
pressure on virgin resources
 Clothing & textile recycling saves
Energy and Reduces Pollution.
 Clothing & textile recycling reduces
the demand for dyes and fixing agents.
.

15.  As textile mill sludge contains organic
matter, it can be turned in to sludge ash by
igniting it to 800 c for two hour. This sludge
ash can be used in concrete.
.

16. Conclusion
 Textile mill sludge can be successfully
used as building material by adding it in
M20, M25 and M30 grades of concrete up
to 32% ultimate comprising on
compressive strength.
 Workability of concrete goes on reducing
as percentage of sludge increases.
 For all grades considered that 28 days
average compressive strength fall down
with sludge percentage beyond 32%.
