Impact of Textile Effluent on Environment
Effluent is the stream of excess chemical liquor from an industry after using in original operation.
Textile industry employed various process such as sizing, desizing scouring, bleaching, dyeing, printing, finishing etc.
After using original operation large amount of excess liquor discharge to drain.
In a practical estimate, it has been found that 45% material in preparatory processing, 33% in dyeing and 22% are re-processed in finishing

Textile Wastewater Treatment in BangladeshMahmudul Hasan
What is wastewater, textile wastewater treatment, Major Pollutants in textile wastewater, Steps of textile wastewater treatment, Brief overview of textile wastewater in Bangladesh.
Water is an inevitable part of textile and apparel processing industry .The textile fibers, including wool, silk and cotton is prepared for fabrication by scouring processes which involve the use of quantities of water. The standards of purity required are high in all cases but very with the specific operations.
What is Waste?
Waste is undesirable, unwanted material which is inevitable & any type of material which we throw.
Types of Waste -
1 Preconsumer Waste - is a material that was discarded before it was ready for consumer use. Pre-consumer recycled materials can be broken down and remade into similar or different materials, or can be sold "as is" to third party buyers who then use those materials for consumer products. Preconsumer textile waste usually refers to waste by-products from fiber, yarn, textile, and apparel manufacturing. It can be mill ends, scraps, clippings, or goods damaged during production, and most is reclaimed and reused as raw materials for the automotive, furniture, mattress, coarse yarn, home furnishing, paper, and other industries
2 Postconsumer Waste -
Postconsumer textile waste usually refers to any product that the individual no longer needs and decides to discard due to wear or damage and normally includes used or worn clothing, bed linens, towels, and other consumer textiles. Postconsumer waste which can be recovered are clothing, drapes/curtains, towels, sheets and blankets, clean rags and sewing remnants, table cloths belts hand bags paired shoes and socks.
The environmental impact of paper is significant, which has led to changes in industry and behavior at both business and personal levels. With the use of modern technology such as the printing press and the highly mechanized harvesting of wood, disposable paper has become a cheap commodity. This has led to a high level of consumption and waste. With the rise in environmental awareness due to the lobbying by environmental organizations and with increased government regulation there is now a trend towards sustainability in the pulp and paper industry.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

3. 1.What are the Effluents ?
▪
Effluent is any liquid waste (other than surface
water and domestic sewage) that is discharged as a
bi-product of their production.
4. 2.WHAT IS AN EFFLUENT TREATMENT PLANT?
▪ EffluentTreatment Plant or ETP is one type of waste water
treatment method which is particularly designed to purify
industrial waste water for its reuse and it’s aim is to release safe
water to environment from the harmful effect caused by the
effluent.
EffluentTreatment Plant
5. 3.Introduction
▪ In textile mills mainly, the waste water discharge is the effluent which
contains :
▪ Organic matter
▪ Inorganic matter
▪ Dissolved solids
▪ Suspended solids
▪ Dyes
▪ Chemicals & Auxiliaries
▪ Metal Toxicants
9. 7.Classification of textile wastes
▪ Hard to treat
- Colours, Metals, Phenol
▪ Toxic organic compounds
▪ Phosphates
▪ Non-biodegradable surfactants
▪ Hazardous or toxic
▪ Dispersible
10. 8.Stages of Effluent treatment process
▪ Primary
▪ Removes identifiable suspended solids and floating materials.
▪ Secondary
▫Also known as biological treatment.
▫ Removes organic matter that is in soluble form or colloidal form.
▪ Tertiary
▫ Removes sodium and chlorides ions.
▫ Removes additional suspended solids including algae, fungal bacteria.
13. *Screening : Coarse suspended matters such as rags, pieces of fabric,
fibres, yarns and lint are removed. Bar screens and mechanically cleaned fine
screens remove most of the fibres.
* Sedimentation:
•This process is particularly useful for treatment of wastes containing high
percentage of settable solids or when the waste is subjected to combined
treatment with sewage.
•The sedimentation tanks are designed to enable smaller and lighter particles
to settle under gravity.
* Equalization: These effluent streams are segregated and stored in
separate tanks, and this liquid effluent may be dosed at regular and uniform
rate which is known as equalization.This process is carried out to equalize the
pH.
15. * Neutralization:• Neutralization helps in maintaining the pH
range of 6-9.
▪ • Mercerizing discharges are highly alkaline liquors, and carbonizing
discharges are highly acidic nature. Diluted by adding of H2SO4 or
CO2 or flue gas.
* Chemical Coagulation:•To remove colour, suspended solids,
colloidal particles, the effluents are treated with coagulants like
Alum, Ferrous Sulphate, Ferric Chloride, Sodium Aluminate and
activated Silica in a clariflocculator.
• Acids such as polyelectrolytes are used along with coagulants to
improve coagulation. Sludge is separated and dried on sand beds.
Treated effluent is subjected to secondary treatment.
16. 11.Secondary Treatment
▪ * Activated Sludge Process : • Here the effluent is continuously
exposed and subjected to biological degradation carried out by
‘Microbial Floc’ suspended in reaction tank into which oxygen is
introduced by mechanical means.The effluent from this tank is
allowed to settle and a portion is recycled.
*Trickling filtration : • Effective aerobic biological oxidation
method widely used.The effluent is sprinkled over a bed of broken
stones. Bacterial slimes formed on the stones oxidizes Organic
matter during the passage. Effluent is finally settled and discharged.
17. 12.Comparison of trickling filters with
activated sludge systems.
Trickling Filters
a)Bacterial growth is fixed on the
media.
b) All solids from the settler are
wasted.
c) Less sensitive to shock loading
- more stable.
d) Produce insects and odors.
c) Less effective in removing
disease causing organisms.
e) Low operating costs.
Activated sludge systems
1. Bacterial growth is suspended
as a dispersed floc.
2. Solids from the settler are
partially recycled.
3. More sensitive to shock
loadings, require closer process
control.
4. Produce spray clouds.
5. More effective in removing
pathogens than trickling filters.
6. High operating costs.
19. 14.Tertiary Treatments
▪ *Evaporation : • It is a simple process of boiling the waste and
vaporizing the waste water.This process is useful only when the
recovered water and solids are re-used and recycled.
•Various fuel systems like coal, wood, use of stem are employed for
evaporating these effluents.
*Dialysis : •This is a method of separating solutes from the solution
based on the difference in the rates of diffusion.
•This process is mainly used for recovering NaOH from mercerizing
and H2SO4 from carbonizing.
*Removal by algae : •This process is much similar to oxidation
ponds. Algae requires Potassium,Calcium and magnesium.Traces of
Manganese cobalt and Copper are required.

▪ • Reduces the depth of penetration of sunlight - decreases photosynthetic
activity and dissolved oxygen.
▪ • dyeing cotton with reactive dyes are highly polluted and have high
BOD/COD, coloration, and salt load.
▪ • Marrot and Roche Review :
1)Physical methods include precipitation (coagulation, flocculation,
sedimentation)
2) Adsorption (on activated carbon, biological sludges)
3) Filtration (Micro filtration, Nano filtration)
4) Membrane processes (osmosis and reverse osmosis)
22. A flow diagram for treatment of cotton
textile mill waste
24. Recommendations for effluent management
in textile industries
▪ •The multiple effect evaporation with crystallizer has been installed
for recovery glauber salt.
▪ • Reverse osmosis membrane filtration can produce colourless
treated effluent with dissolved solids as low as 196 mg/l and zero
hardness.
▪ • Recycling and reuse of the treated effluent directly conserve natural
resources and a step towards sustainable development.
▪ • Low polluting stream contains nominal dissolved solids so that it
meets quality requirement for its reuse or disposal after treatment.
25. Recommendations for effluent management
in textile industries
▪ • For effective effluent management as follows:
1)The highly polluting effluent stream can be segregated and treated
separately.This stream has low volume and as such, it can be disposed of
through solar evaporation pond where adequate land is available.
2)The other low polluting streams can be given primary/secondary/tertiary
treatment to meet the disposal standards or for use in industry for
appropriate operations.
3) Dye bath effluent is to be treated using a nano filtration system and wash
water can be treated separately in primary/secondary/tertiary treatment to
meet the disposal standards or for reuse. It can also be treated with reverse
osmosis system to recover and recycle water.
4)The reject stream of reverse osmosis can be disposed of through solar
evaporation ponds or other evaporation system.
