Nanofiltration Textile Industry

Tighten regulations on waste disposal to stop the industrial world for the manufacture of cloth in finding a solution to reduce the amount of waste produced in the manufacturing center. As an industry that generates large amounts of waste, textile manufacturers have to find practical methods to meet regulatory standards without compromise to their method of production. Membrane filtration, especially in the use of nanofiltration be the answer to many of these problems. With the application of nanofiltration, not only can reduce the number of textile manufacturers sent to waste water disposal, but has the potential to recover and dye tank for reuse. Overall result will be significant cost savings and reduce the ecological footprint.

Membrane filtration is used in many industries to separate, concentrate or liquid fractionation with amazing efficiency at the molecular level. While the most common application of membrane filtration to reverse osmosis water purification and municipal waste water, especially sea water desalination, this technology is applied to the process fluid in various applications. This allows important products harvested filtration membranes, such as whey protein in the milk industry and the vital fluid purified and reused as electrodeposition paint in the automotive industry. In connection with the textile manufacturing industry, the most interesting features of nanofiltration for wastewater treatment and recovery options products. Operating at lower pressures than reverse osmosis membrane, nanofiltration can cause a decrease in the very high quality, but offers a more economic level of service, if applicable and appropriate treatment pretreatment.

Tested in three effluent stream Nanofiltration generally in a textile factory and show very promising results. Polyvinyl alcohol (PVA) was used in both light and reinforcing fibers. PVA is extremely toxic, but also very modern textile production. The effective recovery is desirable chemical and environmental finance. NF membranes have been tested and proven to be very effective in removing the PVA wastewater. NF membrane filter is also applied to wastewater containing dye textile mills. Dye so employed throughout the industry for the manufacture of textile waste yield and may contain salt and the addition of sulfide unused colors. Nanofiltration can not only remove stains from a wide variety of waste water, but also salts and sulfides. Nanofiltration using this solution will significantly improve the water quality and the potential to allow the dye to be reused in the manufacturing process. Showed Special study membrane filtration has been very effective in the recovery of dye penetration test agent concentration and optical brighteners.

Open the door to the development of nanofiltration membrane filtration as a practical technology for the textile industry to meet the discharge regulations. Although there are many potential applications, the following common potential in all of them: the opportunity to re-use valuable chemicals and the ability to reduce the ecological footprint of the entire industry.
