1) The document discusses the removal of red acid dye from textile industry wastewater using bagasse treated with different surfactants extracted from plants and microbes.
2) Three surfactants - A10, R10 and P21 - were extracted and used to treat bagasse. The treated bagasses - BA10, BR10 and BP21 - were tested for dye removal efficiency.
3) BA10 showed the highest dye removal of 99.4% at pH 7, while BR10 and BP21 achieved 98.1% and 98% removal respectively. BA10 also had the fastest degradation within a short time period compared to the other treatments.
Oligomer & the importance of Oligomer remover-------
Oligomer is a smaller chain length of polyester made up of two or more molecules of basic ethylene terephthlate i.e. dimer or trimer, produced as a side reaction during the manufacture of polyester. The Oligoester because of its smaller chain length is in the form of a fine powder which is entrapped is basic polymer and migrates to the surface during high temperature polyester dyeing.
Higher the depth more is the displacement of Oligomer to the fibre surface. Typically polyester fibres contain between 1.5-3.5% by mass of low molecular esters, the principal oligomer being cyclic tris (ethylene terephthalate) with smaller quantities of dimer, pentamer & other compounds. Approximately 0.1 % to 1.0 % of Oligomer is produced as a side reaction in the manufacture of basic polyester.
Oligomer & the importance of Oligomer remover, problems caused on its deposit, Removing Art, Solutions----
The textile dyeing industry consumes large quantities of water and produces large volumes of wastewater from different processes in dyeing and finishing processes. The low-cost, easily available naturally prepared coagulants like moringa seed powder, maize seed powder, green bean powder and tamarind seed powder as an alternative to recent expensive coagulant methods for reactive dye removal has been investigated in this study. Various process parameters like pH, coagulant dose, flocculation time and also its optimization were exploited. The maximum percentage color removal was found to be 80.26, 78.30, 74.04, 72.68 and 70.53 for moringa, corn, aluminium sulphate, green bean and tamarind, respectively, at pH 9.0, coagulant dose of 30 mgL-1, flocculation time 120 min. The sludge volume index (SVI) was calculated for these parameters including process optimization. Natural coagulants were better coagulant than aluminium sulphate which corresponds to color removal and sludge volume index.

Removal of Harmful Textile Dye Congo Red from Aqueous Solution Using Chitosan...IJERA Editor
Color is an important aspect of human life. Textile industries are the major consumers of dye stuffs. During coloration process, 10 to 15 percent of the dyes will be lost and this will be discharged with the effluents coming from textile industries. These are very difficult to degrade and they may degrade to form products that are highly toxic to human. Today, methods such as coagulation, flocculation, activated carbon adsorption, etc. are available for the removal of dyes. These are all quite expensive and difficult to degrade. Chitosan is a natural hetero polymer derived from chitin. Chitosan has proved to be effective in removing hazardous compounds from environment due to its multiple functional groups. It is available as flakes and powder. In the present work, chitosan beads were prepared and modified with a cationic surfactant CTAB for the removal of dye Congo Red. Batch experiments were conducted to study the effect of CTAB concentration, contact time, agitation speed, adsorbent dosage, initial dye concentration and pH. Batch equilibrium data were analyzed using Langmuir and Freundlich isotherm. Bach kinetic data were analyzed using Pseudo first order kinetic model and pseudo second order kinetic model.

In Malaysia, oil palm is a very significant crop. In the worldwide, the biggest palm oil exporter and producer is Indonesia and Malaysia is the 2nd exporter and producer. the production of crude palm oil (CPO) was increased significantly from 92,000 tonnes in year 1960 to 17.6 million tonnes in year 2009, The process to extract the palm oil needs massive and huge water quantity to sterilize the fresh fruit bunches (FFB) and clarify the extracted oil.
Comparative Study for Adsorptive Removal of Coralene Blue BGFS Dye from Aqueo...IJERA Editor
Textile industries represent biggest impact on the environment due to high water consumption and waste water discharge as government control water pollution by setting strength regulation for waste water discharge, removal of color from waste water becomes more and more essential and attractive. Adsorption technology is very efficient in treatment of textile effluent. In this paper comparison of adsorption phenomena of textile dye Anthraquinone blue onto two different adsorbents MgO nano powder and Fe2O3 amorphous powder has been studied for removal of said dye from aqueous solutions. The adsorption of Anthraquinone blue on adsorbents occurs by studying the effects of adsorbent amount, dye concentration, contact time and pH of solution. All results found that MgO nano powder and Fe2O3 provide a fairly high dye adsorption capacity, which combined with their fulfilment of pollution control board’s standards, lack of pollution, lower environmental hazard and low-cost makes them promising for future applications. The present work also provides information on optimum value of different operating parameter for dye removal by two adsorbent.

Operational parameters affecting the removal and recycling of direct blue ind...IJEAB
In this work the ability of “bleached” oil mill solid waste to reduce the dyestuff content in industrial textile wastewater was studied. Bleaching treatment consists in a preliminary oil mill solid waste management with NaOH and NaClO2 for obtaining cellulosic materials, mainly removing lignin from the waste surface. Thus, a novel bioadsorbent from agricultural residues, named bleached olive pomace (OP), was presented. Direct Blue 78 was studied as a model azoic dye. Experiments were planned to study the effect of different initial conditions on the adsorption processes: oil mill waste amount as grains and as a fine powder (OPP), solution temperature values, initial dye concentration, pH values and electrolytes influence. The results showed that the adsorption process using bleached oil mill waste determined an excellent degree of water color reduction, reaching the best work conditions when pH 2 and OPP were used. The presence of electrostatic interactions was also suggested. The adsorption appeared to be influenced by temperature values showing an endothermic character. Interestingly, to confirm the role of ionic interactions between dye and sorbent at pH 2, fashionable results were obtained. The adsorption process was verified also at pH 6 with 100% of dye removal in presence of both NaCl and Na2SO4 avoiding the aforementioned strong acid conditions. A very important aspect of this work is the recycle of both the dye and the adsorbent, with particular attention to the dye reuse for coloring cotton fabric.

Discussion
Textile industry is the fastest growing industry with the requirements of several
types of dyes for dyeing and printing of clothes. The effluent from these industries is
the major cause of environmental pollution, containing smaller amounts of dye are
highly detectable, causing environmental pollution and serious health hazards such as
severe headache, profuse sweating, mental confusion and similar health hazards. Dye
is a colored substance applied to fabrics to impart a permanent colour, which is not
removable by washing or drying. W.H. Perkin was the first to use dye in 1856. As per
the reports of Central Pollution Control Board (CPCB), commercially produced dyes
and its intermediates in India tends up to a million. Based upon the chemical
structure, dyes can be classified as, Natural dyes and Synthetic dyes.

Results
Among three surfactants such as P21, A10, R10 treated with bagasse,
BA10 shows 99.4% removal at pH 7 while BR10, BP21 shows 98.1
and 98.0 respectively at pH 7. BA10 has fast degrading activity in
short period of time when compared to BR10, BP21.
The environmental problems created by the textile industries have received
increased attention for several decades because of contaminated effluents,
which mainly arise from dyeing processes. The present project shows that
if low cost adsorbents perform well in removing dye colour they will be
used widely in the industrial sector to improve profit and to minimize the
cost in efficiency in the industrial sector. These low cost biosorbents also
offer a lot of promising benefits for commercial purposes in the future.
Various researcher are working on removal of dyes using biosorption as a
green approach , because of its low cost ,no hazardous chemical formation.
