This presentation discusses textile sludge management. It will cover textile sludge, how it is produced, its characteristics, and treatment processes. The presentation also explores reuse options for textile sludge, such as incorporating it into cement and concrete as a substitute for regular aggregates, using it to manufacture bricks, and employing activated sludge processes to induce microbial growth and further treat wastewater. The conclusion emphasizes that sludge is inherently produced from wastewater treatment and that further research into additional reuse methods is needed.

4.  Sludge is the solid material removed during the treatment of
wastewaters. The term is also sometimes used as a general
term for solids separated from suspension in a liquid material
usually contains significant quantities of wastewater. There
are three kinds of sludge: sewage sludge from municipal
treatment works, septage pumped from septic tanks, and
industrial smudges. All three are a growing management
problem in this state, and throughout the world. A primary
treatment plant removes solids physically, by screening out
larger objects and allowing grit and other materials to settle
in settling tanks. This removes most solids, but leaves
suspended matter and dissolved substances in the discharged
water, or effluent.

5. The Sludge management consist of different distinct
functions such as Solid Liquid separation, Sludge
Thickening, Sludge De- watering and Sludge disposal.
The following Equipment's manufactured by Confident
play significant role in Sludge Management Process.
 High Rate Solid Content Clarifier
 Sludge Thickener
 Filter Press
 Hydro Extractor
 Decanter

6. How sludge is produced from Textile
mill wastewater

8. Characterization of sludge:
Physical and Chemical parameters of
Textile Mill Sludge

9. Textile ETP Sludge PROCESS:
 Collection from effluent treatment plant
 Sludge is dried
 Sieved to remove dust
 Mixing Proportion is 4% ,8% ,12%
 Then the sludge was mixed along with cement
concrete and mortar
 The sludge was found to have very high
concentration of pollutants like sulfate, chloride,
color etc.

10. The Sludge Use in Landfill :
Commonplace requirements in many industries are to minimize the amount
of waste generated and to reduce the overall impacts on the environment.
Pulp and paper industries and automobile manufacturing unit generate a
considerable amount of diverse hazardous waste. There are now standard
practices or norms available for such industries. A number of methods are
used for disposal of such kind of waste and reduce the concentrations of
contaminants. The waste after conventional treatment results into sludge, ash
or cake which contains residual contaminants mostly consisting of heavy
metals / inorganic concentrates. These waste ends up in waste molds or a
landfill. In India, about 4.4 million tones/ annum of Hazardous Waste, which
ends up for disposal. Unless this is scientifically disposed, it could cause
serious hazard to human health.
Why use a Hazardous Waste Landfill
 Low costs compared to other disposal options
 Often the only final disposal route for residues arising from other
HWM options (e.g. ashes from incineration processes)
 Well-designed landfills can be unobtrusive

11. Brick manufactured from incinerated sewage sludge ash and clay is
investigated. The results of Atterberg limits tests of molded ash-clay
mixtures indicated that both plastic index and dry shrinkage decrease
with an increasing amount of ash in the mixture. Results of tests
indicated that the ash proportion and firing temperature were the two
key factors determining the quality of brick. Increasing the firing
temperature and decreasing the amount of ash in the brick resulted in a
decrease of water absorption. The appropriate percentage of ash
content for producing quality bricks was in the range of 20 to 40% by
weight with a 13 to 15% optimum moisture content prepared in the
molded mixture and firing at 1,000°C for 6 h. With 10% ash content, the
ash-clay bricks exhibited higher compressive strength than normal clay
bricks. This study showed that the pulverized sludge ash could be used
as brick material. The bonding strength can be further enhanced by
controlling operating conditions.

12. A Special Way to Manage Textile
Sludge: Activated Sludge Process
Process in which a mixture of
wastewater and microorganisms is heated and
mineral.
Leads to oxidation of dissolved organics
After oxidation, separate sludge from wastewater
Induce microbial growth

13. Conclusion:
 Sludge is produced from the treatment of
wastewater. This is inherently so because a primary
aim of wastewater treatment is removing solids
from the wastewater.
 After producing sludge the major fact is reuse of
sludge. we describe 2 way of reuse of sludge. The
sludge also use in agriculture regulation.
 We should find more way to reuse of sludge.
