Distillery industries in India pose a very serious threat to the environment because of the large volume of wastewater they generate which contains significant amount of recalcitrant compounds. Distillery spent wash has very high COD and BOD with low pH and dark brown color.
The treatment of spent wash using various treatment technologies and reactor configurations has been widely explored. However, none of the work reports about the performance of most advanced hybrid configuration of reactors at various operating conditions for the treatment of spent wash. Therefore, the study has been undertaken to assess the performance of Hybrid Anaerobic Baffle Reactor (HABR) for the treatment of distillery wastewater (spent wash). The main objective of the paper is to explore the use of anaerobic digestion as complete solution to treat BOD and COD in the same reactor in conjunction with suitable oxidation technique.
In India there are major wine and beer producers has setup their plants in Utter Pradesh, Maharashtra, Tamilnadu, Madhya Pradesh etc they are producing alcohol by using Molasses as raw material. This molasses contains 7 to 8% glucose which is converted in to alcohol by fermentation process. First molasses is diluted to by adding water and adjust the total dissolved solids up to 7 to 8%. Then Yeast to be added in diluted molasses solution and fermentation takes place. As process go up glucose is converted in to ethyl alcohol and carbon dioxide. This carbon dioxide will free as a gaseous form which either collected separately. After sufficient conversion from glucose in to ethyl alcohol this solution now called beer solution. This beer solution then passed through distillation column. Based on temperature difference ethyl alcohol separated from beer solution and condensed in to liquid form. After distillation column spent liquor contains lot of dissolved impurities mainly organic, color, TDS, oil and suspended solids which is very difficult to treat by regular effluent treatment plant. Here membrane technology has answer. This spent liquor after distillation column to be treated by first Ultra filtration membrane followed by Nano filtration membrane and recycle fresh water again for fermentation plant.

As per requirement product milk is to be processed further.Membrane technology will definitely helpful for improvement in quality, saving in energy as well as in some cases recovery of byproducts.
Among the food industries, dairy industry is most polluting in regards to its large water consumption because water has been a key processing medium. Environmental protection agencies have started a strict vigil for banning of wastewater discharge into the natural resources of water. This has made the water treatment more expensive thereby becoming a huge burden for the industries. Thus, water reuse has become an environmentally and economically feasible solution. But water reuse becomes more challenging by employing conventional treatment processes due to wide fluctuations in industrial effluent quality. It has been shown that membrane processes to be convenient to treat dairy wastewater for recovering of milk components and producing reusable water i.e. usable in the washing of floors, and replacing of water in cooling towers or boiler, etc. But the major problem facing by the membrane installers is fouling of membrane materials, however many of advanced techniques were developed for overcoming the fouling problems. Depending on the size of permeable particles, membranes are divided into four major types namely Microfiltration membranes (MF), Ultra filtration membranes (UF), Nano-filtration membranes (NF) and Reverse Osmosis membranes (RO).

Dye stuff industry is using bulk quantity of water for the production of dyes. There are different types of dyes namely Reactive, Acid, Direct, Disperse, Pigment and food etc produces in India.
During production of above dyes, industry generates high colored wastewater. This wastewater contains lots of impurities mainly organic and inorganic substances which either in dissolved form or suspended form. Traditionally primary and secondary treatment requires chemicals like Lime, Ferrous ammonium sulphate, Polyelectolytesetc and power and huge space and difficult to treat biological treatment. Even after doing all primary, secondary and some time tertiary treatment, the final quality of treated wastewater does not match with the Pollution board parameters due to high load of organic and inorganic matter as well as not able to give retention time in secondary treatment. Here membrane technology helps to recover valuable color and reduce major polluted parameters mainly COD, BOD, Color, Suspended solids, Oil and Grease and TDS.
There are different types of membranes available to treat any kind of effluent wastewater. For dyestuff industries there are special membrane is available which can easily reduce color from wastewater. In dyestuff industries the color is due to the organic matter so naturally COD and BOD will also reduce. Now this colorless wastewater contains only inorganic salts. This salty water can be further treated by another special membrane which will remove salts from wastewater and can be reuse in industry again as this water is as good as raw water.

Membrane technologies are increasingly becoming useful components of pharmaceutical production processes. For some time, membrane separation technologies of reverse osmosis, ultrafiltration and microfiltration have been used to concentrate and purify both small and large molecules. More recent applications of membrane technologies cover a broad range of separation, concentration and purification needs. For example, pharmaceutical waste streams can be treated by nanofiltration or pervaporation to detoxify them and/or reduce the volume of waste requiring incineration.
Solvent vapors can be removed/recovered from nitrogen/air emission by vapor permeation. Enantiomeric/ other isomeric mixtures can be separated by liquid membranes or membrane-based multi-phase extractive enzymatic resolution. Nanofiltration or pervaporation can be used to enhance synthesis reaction conversion. High performance tangential flow filtration can be used to fractionate protein mixtures whose molecular used to integrate clarification and chromatographic processes for downstream processing of biomolecules. Fluid Sep Technologies attempts to provide a perspective of these developments in laboratories, pilot plants and commercial applications.

India is a largest producer of sugarcane in entire world. Our major sugarcane producer states are Uttarpradesh, Maharashtra, Gujarat. In India there are lots of sugar manufacturing unit has setup their plants to produce quality sugar. At present they are producing quality sugar by traditional method i.e. chemical process. Initially sugarcane juice extract by crushing sugarcane in crusher plant. The % of total solids is ranging from 5 to 6%. This sugarcane juice then processed through several steps and finally crystal sugar produced and as by product molasses generated.
During process of producing crystal sugar, initial stage sugar juice contain lot of dissolved and un dissolved impurities. Un dissolved impurities can be removed by passing sugarcane juice through filter press. But dissolved impurities mainly protein, fats, minerals and oil are very difficult to separate from sugar. Traditionally all dissolved impurities are removed by chemical process which is very lengthy and requires maintenance.
Here membrane technology can make difference. It not only removes the dissolved impurities mainly high molecular weight protein, fat, oil but also concentrate the sugar cane juice by removing pure water from juice. Resulting saving lot energy in evaporators. Secondly all impurities are removed by membrane so it does not require any chemical process resulting saving chemicals and maintenance cost and process time will much faster.
Process:
After crusher plant sugarcane juice to be collected in storage tank and then passed through filter press which will remove major suspended impurities. Thereafter juice will passed through micron bag filter followed by micron cartridge filter which will suspended and colloidal impurities down to 5micron level. Now sugarcane juice is free from suspended solids but having dissolved impurities. This sugarcane juice then passed through modified Ultra filtration membrane system. This Ultra filtration membrane will remove all high molecular weight impurities like Protein, Fat and Oil and allow sugar to pass through membrane. As all major high molecular weight impurities removed the color of sugar juice absolutely colorless which originally brownish color. This color was due to the high molecular weight impurities.
After ultra-filtration process sugar juice then passed through Nano filtration where sugar is concentrate from 6% to 24% i.e. four fold concentration is possible by Nano filtration by removing water along with all major salts. Resulting saving in energy in evaporators as well as quality of sugar is improved. Finally this concentrated sugar to be taken for further evaporation and then convert in crystal sugar.
Here the main advantage of membrane system is that there is no phase change i.e. liquid to liquid separation and concentration is possible. Resulting saving in energy, saving in chemical and process time is faster compare to conventional method.
Treatment scheme:
Filter press.
Micron bag filter.
Micron cartridge filter.

There are many large and medium paper industries located in India. It covers major demands of world requirement and this industry is in demand. Paper industries require bulk quantity of treated water for production of good quality of paper. So naturally wastewater quantity is also high. This wastewater contains hazardous chemicals like lignin, Ligno sulfonate, Caustic, Fibers and so on.
These chemicals are very costly. After processing leftover wastewater contains high quantity of chemicals which requires to recover from waste water if possible. Here membrane technology is playing a vital role to recover valuable chemical from wastewater. It not only recovers valuable chemicals but also recycle fresh water which can reuse in process again. Now a day pollution authority demands to recycle as much as water from treated effluent by applying membrane technology as it is proven for almost all industries effluent wastewater.
In Paper industries after process of production of paper, the wastewater contains high amount of chemicals such as Fibers which can be recycle in process by membrane technology. We, Fluid Sep Technologies, Ahmedabad has done extensive trial to recover fibers from wastewater by applying membrane technology. We can recover 90% to 95% of fresh water from wastewater and fibers are concentrating to recycle in process again. This recovered fiber may be a raw material for hard board industry. By this process we can also control all parameters as per pollution board limit. We have pilot plant facility to conduct trials to check the feasibility of membrane technology either at customer’s site or at our factory.
Treatment scheme:
Pretreatment of membrane system.
Ultra filtration system.
Nano filtration system.
Post treatment of membrane system.
[A] Recovery of pure water from wastewater: 95%.
[B] Concentrate mass disposal: used as a Raw material for hard board industry.
The above result achieved by membrane technology are encouraging and also approved by Pollution board authority.

India is the largest producer of leather and Leather goods. It covers major demands of world requirement. These tannery industries are setup in different parts of India i.e. Tamil Nadu, West Bengal, Utter Pradesh. There are two types of tannery industries namely
[1] Raw leather processing and.
[2] Finished leather processing.
[1] Raw leather processing and.
[2] Finished leather processing.
In Raw leather processing industries, Raw skin to be processed and convert in to semi finished or Gray Leather by removing soft skin, hair, fat, protein, oils with the help of chemicals mainly with Sodium chlorides and chrome. During this process there is large amount of wastewater generated which is very hazardous and without perfect effluent treatment is not possible to dispose. With existing effluent treatment i.e. with primary and secondary treatment it is not possible to control all parameters as per pollution board limit.
Similarly in finished leather processing industry, the gray or semi finished leather is converted in to finish leather by applying chemicals mainly chrome base and dyes and machining to add softness to leather. Again there is large amount of hazardous wastewater generated and very difficult to control parameters by primary and secondary treatment.
In traditional practice chrome tanning only 50 to 60% of the chromium applied is taken by the leather and the balance is discharged as waste. This chrome is in form of Basic chrome sulphate and is highly polluted and very difficult to treat by conventional method and generating waste sludge. This sludge is not easy to dispose inland. The environment limit for disposal of this basic chrome is only 2ppm. To control this parameter through conventional method is not possible.
In India all tanners has setup individual or wherever possible central effluent treatment plant in their area. But with existing effluent treatment process still some parameters like TDS, COD, BOD, Suspended solids etc are not controlled as per pollution board limit. Surrounding of tannery industries is also get polluted due to disposal in nearby land or river. Looking to future fresh water demand is increasing day by day, now government authority is demanding to recycle pure water from wastewater.
Here the membrane technology will be helpful for above requirement. Membrane technology can be added in existing effluent treatment as a tertiary treatment. Membrane process will definitely control all parameters as per pollution board limit as well as recycle pure water from wastewater depending upon quality of outlet of secondary treatment.
Membrane technology is widely applied for water treatment to convert Sea water or Brackish water in to drinking water or process water. It is also widely used for other process industries where concentration, separation, purification and /or clarification required for aqueous solution.
We at Fluid Sep Technologies, Ahmedabad has facility to conduct pilot scale trial either at customer’s site or at our factory to check the feasibility of membrane technology for controlling all parameters as per pollution board limit and also recycle pure water as much as possible.

India is largest producers of textile goods like Synthetic yarn, Cotton Yarn, Clothes, Hosiery etc. It covers major demands of textile goods of world requirement. During manufacturing of textile goods there are large amount of wastewater generated. This polluted water containing hazardous chemicals. This effluent should be treated as per direction given by pollution board authority so that disposal will not be a problem for industries.
In general textile processing units has setup effluent treatment plants either individually or wherever possible central effluent treatment plants. Existing effluent treatment covers Primary, Secondary and in some case Tertiary treatment by normal method. Even though the above treatment scheme is not able to control parameters as per pollution board limit. Still some effective technology is required to control all parameters and if possible recycle pure water as much as possible as now it is future demand to save fresh water.
Membrane processes have many cost effective applications in the textile industry. The cost competitiveness results from: The ability to recover materials with value, recycle water reducing fresh water consumption and wastewater treatment costs, the use of a point source approach for minimum capital costs, small disposal volumes which minimizes waste disposal costs, reduction of regulatory pressures and fines improved heat recovery systems. The textile industry is advancing toward more a closed operation. Strategically placed membrane systems will play an important role in recovering chemicals which used to go to the sewer, and in providing the high quality water needed to produce top quality goods the first time, every time.
Here membrane technology has answer. It will be incorporated as a tertiary treatment to control all parameters as per pollution board limit and recycle pure water from wastewater.
