Sugar Processing

Permionics can offer membrane solutions for various applications in sugar industries such as juice clarification, color removal, juice concentration and brine recovery. Integrating our membranes can replace conventional chemical treatments and also the clarifiers that use heavy equipment that lead to high operating costs and associated environmental problems. Our membrane filtration promises superior quality juice with better clarity, much lower viscosity and noticeable color removal.

Color Removal

The sugar industry needs efficient methods in clarifying the raw sugarcane juice in order to improve the quality of the clarified juice and to reduce / eliminate the usage of chemicals (lime). The conventional liming-sulphitation process does not help to remove coloring impurities and thus lends a turbid, dark brown-yellow color to the juice. Our membrane process can help to remove these coloring impurities without any chemical usage thus providing clear and good quality of juice.

Brine Recovery

We offer membrane processes for brine recovery application after the ion exchange chromatography step used for sugar-refining. During the ion exchange resin based decoloring step, a high salt concentration effluent is regenerated from the resin column. Our membranes can handle this stream and recover the brine that can be recycled while the colorants and other impurities remain in the reject.


Juice Concentration

Sugar cane crushing results in the initial juice which has brix of around 12-16. Further after the crushed cane is washed with water to extract more sugar and the juice obtained through this step has a brix of around 6. Our membranes can be effectively deployed to concentrate this juice from 6 Brix to 15 Brix at almost half the cost of evaporation and thus improve the economics.

Membrane Solutions for Pharma

Permionics due to its wide range of membranes available in different make and cutoff is best suited for processing of pharmaceutical bulk drugs, APIs and inetermediates. We supply technologies to pharma for concentration, purification, separation of the compounds cost-effectively, enabling a high-product yield. Our highly specialized membranes can successfully replace centrifugation, extraction, distillation and chromatography wherever possible to provide the most economical solutions.

Impurities Removal from API

In some pharmaceutical processes where the traditional methods for purifying API’s using extraction & chromatography does not work, our membrane can help to purify the API based on the size differences in the API and the impurities. Integrating membranes for purifying API adds value as our membranes offer better savings compared to all other conventional purification technologies.

Solvent / Product Recovery

Fermentation Broth

Recovery of product from the fermentation broth is an important step after any fermentation processes that is done using bacterial, yeast or fungal cells. We provide cross flow MF membrane system that is used for clarification of the broth and subsequently to wash out the remaining product from the cells (called diafiltration) achieving complete recovery of the product. We have experience and have supplied our membranes systems capable of handling cell densities ranging from 2 % to 40% (w/v) present in the fermentation broths.

Separations / Recovery

We offer solutions for recovery of macromolecules like proteins after the fermentation process. Our membranes can be used to separate the proteins from the product and other media components added during the fermentation process. The recovered protein can be recycled back into the fermentation process.
Some biotech applications use enzymes like cellulases, lipases, peroxidases etc. as a catalyst for the reactions, and recovery of these enzymes for reuse is important for improving economics. We offer membrane processes that can be used for the recovery of different enzymes.

Product Concentration

Permionics have pioneered the world’s first membrane for the Papain concentration application and we have also supplied systems for the concentration of Streptomycin.

    • We offer membrane processes that can be deployed for the concentration of the product from the dilute fermentation broth, UF permeates, biocatalysis reaction, natural products/extracts etc.
    • Our membranes can be effectively used for concentration of different organic acids like lactic acid, butyric acid, citric acid etc., obtained from the fermentation broth.
    • We also offer systems for the concentration of dilute extracts/products obtained from the natural products. We have a wide range of membranes that can be used for concentration of dilute products present in aqueous, acidic, alkaline and solvent based streams.
    • The streams obtained from chromatographic separations are dilute and depending on molecular weight of the product we can provide membrane system for concentration of these dilute streams.

CONCENTRATION AND SEPARATION are the two unit processes in which membranes play a vital role. Antibiotics, proteins, enzymes etc can be simultaneously concentrated and dashed/purified by selecting our suitable membranes.

This enzyme is obtained in a dilute form, and finally used as a meat tenderizer and for various health and medicinal purposes. Our membrane systems have been successfully installed for concentration of papain enzyme. Along with concentration, unwanted salts and low molecular weight impurities are also removed making the final product much purer and fetching a higher price in the market. Since membranes remove water at room temperature, there is a saving of 80% of the energy cost over the conventional processes.

Juice Clarification & Concentration

Our membrane process can replace the single or multiple evaporators which have been used in the past to concentrate fruit and vegetable juices. The membrane process is more efficient in energy, time, space and cost saving. Placing our membrane filtration system before an evaporator will increase evaporator efficiency (pre-concentration or pre-powder preparation). A major advantage of our membrane filtration over more traditional separation methods such as vacuum or pressure filtration is that with the option of diafiltration, color is actually gained rather than lost.
Vegetable Juices: Wide variety of vegetable juices can successfully clarified and concentrated and spray dried using our membrane filtration. These include but are not limited to: Onion Juice, Carrot Juice, Celery Juice, Cucumber Juice, Leek Juice, Green Pepper Juice, Aloe Vera Juice, Garlic Juice

Membrane Solutions for the Dairy Industry

Our experience & expertise have enhanced dairy processes
Permionics through its more than three decades of experience can offer a wide range of proprietary spiral membranes i.e. UF, NF and RO with complete systems for multiple applications in the dairy industries viz. milk concentration, milk standardization whey concentration, production of whey isolates, and effluent recycling. Our innovative products are time-tested and have been shown to increase productivity while keeping dairy operations running smoothly and profitably.

Milk Concentration

The concentration of milk by Permionics Sanitory spiral wound membrane has shown potential in a number of dairy plant in India. HPA membrane systems supplied by Permionics easily removes 50% of water from Skimmed Milk & helps to enhance the potential and cost efficacy of the dairy industry.
Milk concentration is primarily applied to the manufacturing of Skimmed milk powder. Integrating membrane technology ahead of the evaporator and spray dryer reduces the operating cost by nearly 50 to 60% as the membrane technology operating cost is nearly 1/10th of the operating cost incurred in the Evaporators. The other advantages are that the concentrated milk solids can be transported at significantly reduced freight and storage costs due to significant reduction in the volumes. Removal of ash from the milk is also another problem which many dairy industries are facing. Permionics provides NF System which can remove the minerals/ ash in the form of Na+ ions in the milk.

Whey Concentration (WPC) / Demineralization

Whey is a by-product from the cheese industry. It has low content of solids and high biological oxygen demand (BOD), which creates a major disposal problem for the dairy industry. Whey protein concentrate is used in many products including nutritional beverages, baked goods, processed foods, and animal feed. By applying our membrane ultrafiltration and diafiltration esses, whey can be concentrated to produce WPC with 35-85% protein.
The purpose of whey demineralization is to make whey products more suitable for human consumption such as Whey-based products for infant formulas, Whey-based beverages, Whey used for lactose production, Whey used as a skim milk replacer in ice cream etc. We offer processes that can be used for the removal of mineral from the whey and also for removal of mineral from lactose.

Protein Enrichment in Whole Milk

The protein content of milk is subjected to natural variations during the year. In cases where the protein content on dry basis is lower than the expectations, we can provide membrane processes that can help in the standardization of milk & the desired protein content in the milk can be achieved without the need of adding milk powders, casein and whey protein concentrates.

Dairy Effluent Recycling

Permionics has developed a robust & novel membrane based technology for the treatment of dairy effluent, where it uses its proprietary HPA membrane elements to recover up to 85% of recyclable quality water from the ETP treated effluent. Our membrane has a unique ability to withstand high COD levels, more than any other membrane available in market. Permionics have installed a HPA membrane system in one of the biggest dairy plants in India, located in Uttar Pradesh.
As the Food and Dairy Industry enters the age of global competition; processing plants are faced with increased regulations. Many of the traditional methods of wastewater treatments such as evaporation reservoirs and holding tanks are no longer financially feasible or environmentally sound. There is a need to improve quality while still remaining cost efficient. PERMIONICS membranes have successfully addressed the problem of water scarcity in dairy industry and our membrane system has reduced the load on the environment by recovering 85% of water.

Membrane Solutions for Edible Oil

Crude vegetable oils consist mainly of triglycerides or neutral oil with fat-soluble and suspended impurities. The nontriglyceride fraction contains variable quantities of impurities such as free fatty acid, phospholipids (gums), color pigments, metal complexes, sterols, waxes, carbohydrates, proteins, water, and dirt. Most of these impurities are detrimental to the quality of the finished product and thus the requirement of purification of crude has has gained more attention. Permionics can offer membrane processes which can help to remove these impurities providing a good quality of oil at much cheaper cost as compared to traditional methods.


The removal of phospholipids (“degumming”) is the first step of crude vegetable oil refining process. Conventional methods uses water degumming where crude oil is treated with water, salt solutions, or dilute acid to remove phospholipids. This process changes phosphatides into hydrated gums, which are insoluble in oil and are separated from the oil by filtering, settling, or centrifugal action. In this procedure, a considerable loss of neutral oil occurs and a large amount of wastewater is produced, and the energy consumption is fairly large. To overcome this we can provide membrane processes for the degumming of crude oil/hexane mixture and this will offer better savings compared to all the traditional methods currently in use.

Impurity Removal

Apart from triglycerides, crude oil contains different impurities such as fatty acid, phospholipids (gums), color pigments, metal complexes, sterols, waxes, carbohydrates, proteins, water, and dirt. Colored materials, some free fatty acids and other impurities are trapped by the reverse micelles and thus can be removed by using our membrane processes. Our membrane processes can also be used for the separation of free fatty acids (FFA) and triglycerides and thus help to reduce the FFA content in the crude oil. The advantages of this technology are that it is simple, it can be done at ambient temperature if required, and it demands a small amount of energy. Further, since no chemicals are used there is no wastewater generation.

Membrane Solution for Textiles

The textile industry is a large consumer of water and continually strives to minimize pollution as regulation becomes stringent, particularly when dyeing cotton and cotton blend fabrics where a lot of salts and color dye pollutants are discharged into water. The conventional processes to remove these pollutants from wastewater are difficult and costly. Due to an increase of cost of fresh water, industries are looking at ways to decrease the water consumption by the reclamation of wastewater. For the solution of this Permionics has been supplying membrane based plants to the textile industry for several years for dye bath & wash water effluent treatment. Permionics has a very extensive experience of deploying membrane technology in the textile industry for brine, caustic, color and water reclamation from the effluent.

Brine Recovery

Permionics has developed membrane systems which have proved to be significant for energy and waste savings by employing membrane systems to reuse textile dye bath brines. HPA NF membrane technology offers a means to recover reusable brine while also providing for more efficient wastewater treatment. Permeate recovered from the HPA NF process contains salt and is suitable to reuse in the dye cycle.

Caustic Recovery from Mercerizing Bath

Permionics has designed and manufactures special alkaline resistant membranes to recover spent caustic from the mercerizing bath. The permeate stream obtained from our membrane systems would comprise of colorless caustic that is free from any starch or cotton fibres and color. Integrating our membranes for recovering and reusing of caustic will reduce the caustic consumption and thus will also reduce the fresh water consumption. This will add value as the load of alkaline effluent coming to the ETP will be reduced by a huge extent and thus the acid consumption for neutralization will also go down substantially.

Color Removal

In the textile industry, the printing operation uses large quantities of water for washing and this generates wastewater stream with fine pigments and binders having high color and BOD. Our membrane process can remove the color and reduce COD & BOD by 90-95% and provide colorless water that can be recycled back to the print machine for reuse directly.


Permionics offers various combinations like Recycle & Reuse, Evaporation & Crystallization in designing Zero Liquid Discharge Systems in accordance with the unique requirement of the customer. The textile operation requires large quantities of water for washing. Thus the generated wastewater is laden with dye and other inorganic & organic impurities giving a stream with high color and BOD. Permionics membrane system removes this color and other impurities and provides a clean water stream that can be recycled back to the different processes for reuse.In order to reclaim maximum amount of water, Permionics have successfully installed the three stage system for various clients. Permionics’ proprietary membranes have the ability to handle the high COD effluent and gives better flux and a longer life due to lower fouling tendency.

Membranes Solutions for Capsule and Jelly

Gelatin is a water soluble high molecular weight protein (20 to 200 KDa) prepared by the thermal denaturation of collagen, isolated from animal skin and bones with very dilute acid/alkali or also even extracted from fish skins. Permionics can offer membranes and membrane solutions for concentration and de-ashing of gelatin extract and add value by making the process more economical compared to conventional technologies.

Gelatin Concentration

Gelatin broths after the extraction process have a typical solids content of 2 – 6 % (w/v). Our membrane can concentrate the gelatin to 10 – 18 % (w/v). Our membrane process will not only concentrate gelatin but also purify it by removing ash and undesired components from the extract. Integrating membranes prior to evaporator improves economics as the evaporator load can be reduced by 70-80% thus adding value to the process. The processes are very energy-efficient and we can provide compact, modular plant design with the completely automated operation.

Gelatin De-ashing

Gelatin extract also contains 0.5-1.5% (w/v) of ash and removal of this is important to increase the purity of gelatin for the various applications it is used for. Our membrane process is used for the concentration of gelatin and will also help for removal of ash and thereby no separate unit operation is required. Thus compared to ion exchange chromatography, membrane offers huge savings because there is no need to have separate unit operation for de-ashing. There apart there is no generation of effluent that generally comes from regeneration of the ion exchange column.

Condensate Recovery

Condensates from evaporation plants used in the gelatin processes can be subjected to our membranes for improving the quality of the condensate to obtain good quality of water that can be recycled back.

Gelatin Recovery

Washings from process plant and equipment contains less than 2% of gelatin which makes it uneconomical to put into the evaporators. Since the operating cost of removing water using membranes is 1/5th compared to evaporation costs, this gelatin also can be recovered by passing it through our membranes. There is a two fold advantage here: one is recovery of gelatin and the other is reducing load on the effluent treatment plant.

Dye Concentration and Desalting

In the manufacturing processes of reactive and acid dyes, salt and low molecular weight complexes are present in the final product liquor. The salt, reduces the solubility and the complexes and intermediates interfere with the brightness of the dyed fabric, thus there is a need for salt-free dye. Our membrane processes can not only concentrate but also dealt the dye and provide the best and most economical solution to the problem.

Ultra Pure Dyes

Most of the applications require highly pure dyes i.e. free from slats as well all the lower molecular weight impurities. Our membrane processes have been very successful in removing these impurities as well as glaubers salt (Na2SO4,) to achieve high strength with high total solids. The higher concentration achieved saves energy as the concentrated liquor is then spray dried at lower energy levels.
Reactive and acid dyes constitute our major applications and we have supplied over 5000 msq of membrane area installed in the Industry for desalting and concentration of Dyes. Our membrane systems are also operating for Food colors concentration and desalting. Tartrazine-yellow and Sunset yellow are examples of food colors where our membrane systems are giving excellent performance with minimum (< 0.1%) dye loss and >95% desalting

Color Removal

Dyes and pigments are highly visible material and thus there is the requirement on industry to minimize environmental release of colour, even in cases where a small but visible release might be considered as toxicologically rather innocuous. Our membrane filtration processes can remove these colors and is very effective in comparison to other chemical and biological treatments used.

Pigment Concentration

PERMIONICS has developed a robust & novel membrane based technology for removal and concentration of pigment from wash water stream. As we know pigments are insoluble non-ionic compounds or insoluble salts and retain their crystalline or particulate structure throughout their application.
As and when pigment is poured in a tank then it is taken out for manufacturing, then the tank is washed thus generates effluent containing water, salt and some amount of pigment. This wash water when passed through ETP plant, which is considered as long process, creates a problem as it is insoluble in nature and settles down in the ETP. For removing these pigments, a huge quantity of chemicals are used, which generate enormous quantity of sludge. Permionics has made a process technology to solve the turbidity and suspended solid issue in the effluent due to pigment, without any chemical treatment. These membranes have large channel diameter so work effectively in presence of pigment which is in un-dissolved form.

Sulphur Recovery

In the Gas processing recovery of pure sulphur from the sulphur slurry is an important process. Permionics can supply membrane systems that can help in the recovery of sulphur from such slurry very effectively. Our membranes can concentrate the slurry and provide a clear permeate stream that can further produce 99% pure sulphur cake.

Produced Water Treatment

Water produced during oil and gas extraction operations constitutes the industry’s most important waste stream on the basis of volume. The oil and gas industry produces approximately 14 billion bbls of water annually and thus proper treatment of this water to remove oils, inorganic salts, suspended solids, microbes, COD, BOD and hardness is important. Permionics can offer a complete set of solutions for treating such water in order to obtain good quality water.

Water for Process & Utility

Permionics can supply membrane systems that can treat the water from different sources like bore well and river and improve its quality by making it more suitable for the processes in oil and gas industries. Depending on the characteristics of the feed water, we can provide suitable pretreatment and membranes to achieve the required specifications of water to be used for the processes.

Acid /Alkali Recovery

We offer membranes for recovery of acid or alkali that are used for pre-treatment or fractionation of lignocelluloses biomass in the biofuel technology. In processes that use acid/alkali treatments extracts are can be composed of hemicelluloses or lignin depending on the pretreatment deployed and our membrane processes can be used to recover and concentrate these streams thus adding value. Acidic treatment for biomass is used in some cases that convert biomass to dilute soluble sugars. We can provide membrane processes for concentration of these dilute sugars and recovery of acids that can be recycled back.

Membrane Reactors for Hydrolysis & Enzymatic Recovery

We provide membrane systems (membrane reactor) for batch as well as continuous enzymatic hydrolysis of biomass i.e. cellulose / hemicelluloses to produce monomer sugars. The membrane system helps to recover the enzymes used in the hydrolysis process that can be reused multiple times and thus improves the economics.

Sugar Concentration

The sugar stream resulting from the enzymatic hydrolysis process is dilute and needs to be concentrated to a desired level before fermenting to produce ethanol. Our membrane processes can concentrate these sugars and also recover water that can be recycled back.

Ethanol Fermentation

We provide membranes for clarification of fermentation broth and can supply systems for batch as well as continuous fermentation i.e. “high cell density recycle concept”. Integrating membranes for continuous cell recycles during the fermentation process increases the overall productivity and also makes the process continuous.
