2. AbstractAbstract
• Textile industries represent an important environment
problem due to their water consumption and produced
large amount of waste water. In many regions of world
with water scarcity, this fact can be an argument to make
wastewater cleaning necessary.
• This project discusses a Cleaner approach for minimization of
waste particle in dyeing effluent.
• The removal of stuff by Composite filter { Nanofibre
(polyethersulfone) film spread over nonwoven needle punched
fabric (Polyester)} was evaluated for reactive dye. Results showed
that membrane treatment is a promising advanced treatment option
for pollution control for textile industry effluents

3. IntroductionIntroduction
 For removing these types of metals and other particle textile industry use ETP
(effluent treatment plant). In this type of plant the removal of particle from the
water is done sufficiently. This type of plant runs with four stage of removing the
effluent. These are Preliminary, Primary, Secondary & tertiary treatment.
 Pressure-driven membrane filtration processes such as microfiltration (MF), ultra
filtration (UF), nano filtration (NF), and reverse osmosis (RO) provide opportunities
for the textile industry to better water by separating its components based on size.
However, widespread adoption of some of these processes has yet to be realized due
to membrane fouling. Membrane fouling is the accumulation of soil, or foulant, on
the surface or within the pores of a membrane. Fouling prolongs processing times,
increases energy and cleaning costs, decreases separation efficiency, and, in severe
cases, may lead to irreversible clogging of the membrane.
 So our aim to develop a composite filter for prefiltration of textile effluents. if the pre
filtration of textile effluent is good the other next process results will go even better.

4. Development of Composite MembraneDevelopment of Composite Membrane
• We all know that non woven fabric is mostly used for filtration process of water for
her messing structure.
• Applying the Nanofibre over it is give control the pore size and give even better
filtration results.
•PES was selected as the Nanofibre membrane material due to its high thermal and
chemical resistance also its appropriate mechanical properties.

• Polyethersulfone (PES) (Mw= 58000 and density of 1.37 g/cm3) was
from DMSRDE lab. As the sub layer of the membrane a technical
polyester non-woven was used. The chemical structure of PES and
DMF is shown in figure. The solvents N,Ndimethylformamide (DMF)
were obtained from DMSRDE lab.

14. ConclusionConclusion
1. Results Show that the ion and other particle concentration will decrease in
all filtered sample from main sample.
2. Result Show that the flux permeability value and permeate flux will
decrease simultaneously according to thickness of nonwoven fabric and
also Nanofibre.
3. The removal efficiency of composite sample is 75%. & we know the
Microfiltration cleaning efficiency is 70 %.
4. So if we use this filter for pre-filtration of microfiltration process. We
achieve the cleaning efficiency around 91% of textile effluent.
