KMS FLUID SYSTEMS® Membranes for Microelectronics and Bottling Applications
KMS Membranes for Microelectronics Applications In order to achieve both the high quality and the consistent quantity of water needed for the fabrication of today’s extremely compact semiconductor chips, KMS ultrafiltration membranes are an ideal first step. KMS ultrafiltration membranes are an attractive alternative to conventional chemical and mechanical filtration. They provide a more effective and reliable pretreatment process for reverse osmosis and ion exchange. These highly advanced hollow fiber membranes can also be used as the polishing step to remove micron size particles and colloids for point-of-use treatment of 18-megohm water. Additionally, these ultrafiltration membranes are used for the treatment and recycling of wastewater from wafer washing and mechanical grinding operations. This can significantly reduce water usage in a semiconductor chip manufacturing plant and improve the bottom line. Primary advantages of KMS ultrafiltration for microelectronics include: • Production of consistent and high quality water regardless of feed water conditions. • Consistent, high quality water from the ultrafiltration system leads to improved operation of downstream processes. • Highly automated operation for minimal operator attention. • Minimal chemical use reduces the need to purchase, store and handle chemicals. • Minimal waste production and disposal. • Potential to treat wastewater from chip manufacturing for reuse.

Brackish water demineralization creates cost effective drinking water KMS Reverse Osmosis membranes are able to remove both salts and organics from brackish water, enabling communities with limited fresh water to increase potable water for their inhabitants. With plants as large as 51 MGD, KMS is a leader in brackish water treatment. Long lasting, highly efficient membranes reduce demineralization and desalination costs KMS has a family of spiral reverse osmosis membranes for different brackish water applications. These unique thin film composite (TFC) membranes were developed specifically for demanding applications. Ranging in size from 2 ½'' diameter x 40'' long through 8'' x 60'' KMS Magnum Elements and the new 18'' x 60'' KMS MegaMagnum® Elements, providing outstanding efficiency in a small space. KMS FLUID SYSTEMS® ELEMENTS: The best in seawater desalination from the leading worldwide supplier KMS has been supplying membranes for seawater desalination under the FLUID SYSTEMS® brand for nearly 30 years, with installations on the Red Sea, the Arabian Gulf, the Pacific, the Caribbean, the Mediterranean, and every other ocean of the globe. Highly efficient membranes minimize desalination costs KMS has several types of spiral reverse osmosis membranes for different seawater desalination applications. These unique thin film composite membranes were developed specifically for seawater desalination applications. The standard FLUID SYSTEMS® membranes provide 99.6% rejection, perfect for many locations. KMS Premium elements reject 99.8% sodium chloride for single stage treatment at low cost. KMS membranes provide a positive barrier against viruses, bacteria, turbidity, and other water-borne microorganisms for safer drinking water Turbidity Reduction Most surface water used for the production of drinking water requires filtration to remove turbidity and suspended solids before it can be used safely. Conventional treatment systems employ a wide range of techniques to separate suspended solids, such as coagulation and flocculation, settling, or flotation. These techniques require constant monitoring, evaluation and adjustment by operators. KMS membrane systems require only minimal operator monitoring and often run unattended. Membrane systems from KMS provide high quality potable water. Hollow fiber ultrafiltration (UF) membranes deliver excellent turbidity removal in a compact, efficient package. Cryptosporidium, Giarda, Virus Removal KMS PMPW™ membranes are used to remove microorganisms that are chlorine-resistant. Under California Title 22 Surface Water Treatment Rule (SWTR). PMPW™ UF membranes have been certified at: 4-log (99.99%) removal credit for Cryptosporidium 4-log (99.99%) removal credit for Giardia 4-log (99.99%) removal credit for viruses Since PMPW™ Ultrafiltration membranes provide an excellent barrier to water-borne microorganisms, less chlorine is required for disinfection. In addition, the amount of chlorine necessary to maintain the concentration of residual chlorine in distribution is diminished due to the high quality of the PMPW™ Ultrafiltration membrane filtrate. Total Organic Carbon Reduction Small, dissolved, naturally occurring organic molecules react with chlorine to form trihalomethanes (THM) and haloacetic acids (HAA5). KMS PMPW™ membranes reduce Total Organic Carbon (TOC), reducing the potential for THM formation helping municipalities meet stringent regulations. Inorganic Contaminate Removal Low levels of iron and manganese taint many otherwise excellent quality waters. While these minerals pose no health threat, the staining they cause is the source of many complaints. Arsenic and perchlorate, on the other hand, pose significant health risks when found in municipal water. The KMS team of membrane professionals is experienced in designing systems that deal with these inorganic contaminants. Process design often includes pretreatment with either oxidants or coagulants (depending upon the other contaminants in the water) followed by ultrafiltration. Water Softening KMS nanofiltration membranes can be used to soften hard water with no added chemicals. Alternatively, KMS ultrafiltration membranes can be used in conjunction with conventional softening for optimum performance. Desalination To make drinking water from brackish water or seawater, a combination of ultrafiltration followed by reverse osmosis can be very cost effective. Ultrafiltration cartridges used as pretreatment can significantly extend the useful life of reverse osmosis elements. When treating brackish water with relatively low TDS, ultrafiltration can be used both as pretreatment to a reverse osmosis system, and also to produce permeate for blending with reverse osmosis product water. The result is water for distribution that not only tastes good but is less expensive to produce. This approach also permits the designer to significantly reduce the size of the reverse osmosis system and its associated life cycle costs.

KMS Advanced Nanofiltration and Reverse Osmosis Membranes
KMS Advanced Nanofiltration (NF) As advances in nanofiltration (NF) continue to stream into the global marketplace, Koch Membrane Systems continues to maintain its established role as the prime innovator. KMS manufactures nanofiltration membranes in tubular, spiral and flat sheet membrane configurations. Nanofiltration is a low to moderately high pressure (typically 50 - 450 psig) process in which monovalent ions will pass freely through the membrane but highly charged, multivalent salts and low molecular weight organics will be rejected to a much greater degree. Typical nanofiltration applications include water softening, desalination of dyestuffs, acid and caustic recovery and color removal. Take a Closer Look at KMS Advanced Nanofiltration (NF) Nanofiltration is a pressure driven process for separating larger size solutes from aqueous solutions by means of a semi-permeable membrane. This process is carried out by having a process solution flow along a membrane surface under pressure. Crossflow technology uses a high concentrate flow rate to enhance permeate passage and reduce membrane fouling. Retained solutes (such as dissolved salts) leave with the flowing process stream and do not accumulate on the membrane surface. Pores have not been observed in nanofiltration membranes under any microscope, however, water can still pass through the membrane and multivalent salts and low molecular weight organics are rejected. It is difficult to predict the performance of nanofiltration membranes, especially if more than three solutes are present in the solution, since membrane rejection is influenced by the size, structure and charge of the components in solution. As a result, piloting is highly recommended for Nanofiltration applications, even if a detailed feed water analysis is available. The KMS FLUID SYSTEMS® brand of membranes continues to be the premier reverse osmosis (RO) technology available worldwide. The latest innovation is the remarkable MegaMagnum® RO Element with an 18'' diameter and 60'' length. KMS manufactures reverse osmosis membranes in the spiral membrane configuration. Reverse osmosis membranes will reject dissolved and suspended materials including monovalent salts. Close to 99% of all dissolved and nearly all suspended material is rejected by the membrane. For example, water can be softened with a nanofiltration membrane that rejects 85% of salt (sodium chloride) but 99% of the hardness ions (calcium and magnesium). The highest salt rejection rates (99.7% or higher), which can be provided by reverse osmosis membranes, are required for seawater desalination. Reverse osmosis is a moderate to high pressure (80-1200 psig) driven process for separating larger size solutes from aqueous solutions by means of a semi-permeable membrane. This process is carried out by flowing a process solution along a membrane surface under pressure. Retained solutes (such as particulate matter and dissolved salts) leave with the flowing process stream and do not accumulate on the membrane surface. The amount of salt and other impurities is often referred to as TDS, or total dissolved solids. The higher the TDS, the more feed pressure required. Membranes are made with various rejection rates for different applications. KMS produces membrane polymers to cover the full spectrum of reverse osmosis pressure ranges. One of these membrane types is the TFC® (thin-film-composite) family. TFC®-S (''S'' for softening) and TFC®-SR (''SR'' for selective rejection) elements are ideal for low TDS or softening type applications. For higher purity permeate, the ULP® (ultra-low pressure) membrane line offers high water flux and salt rejection in a 125 psi class membrane. When salt rejection is paramount, the TFC®-HR (high rejection) elements offer 99.5% in standard form, or 99.7% in the Premium model. Typically used in brackish water applications with up to 2000-5000 mg/l TDS, they operate around 200 psi When the water is higher in TDS, the XR (extreme rejection) element comes into its own with 99.7% salt rejection and excellent silica and TOC (total organic carbon) removal too. For seawater desalination, KMS offers the SS (single-stage) membrane in various sizes and configurations that allow optimum system design. In the Premium line, salt rejection is at least 99.75%! Many of the SS products are designed to run up to 1200 psi for high salinity/high recovery installations. KMS other main product line is known as ROGA® elements (Reverse Osmosis General Atomic). All ROGA® elements are made with a CA (cellulose acetate) blend membrane, which is resistant to organic fouling due to its smooth surface and neutral charge. The CA membrane operates well on chlorinated feeds, making it ideal for wastewater plants or other applications where chlorine is present or desired to minimize bacterial activity. KMS elements come in standard 40'' lengths, or in the new Magnum® series at 60'' long. The Magnum® series offers several benefits, including fewer interconnectors, o-rings, brine seals; higher active areas; greater productivity; and lower cost per installed gallon.

KMS Tubular Membranes
Tubular Membranes Provide a Constant Flow of Solid Solutions Since the introduction of membrane treatment technology back in the 1970’s, a variety of membrane types and configurations have been developed, including tubular membrane. Tubular membranes operate in tangential, or crossflow, design where process fluid is pumped along the membrane surface in a sweeping type action. The membrane is cast on the inside surface of a porous tube. The feed solution is pumped through the center of the tube at velocities as high as 20 ft/sec. These crossflow velocities minimize the formation of a concentration polarization layer on the membrane surface, promoting high and stable flux and easy cleaning, especially when the objective is to achieve high suspended solids in the MF, UF or NF concentrate. Permeate is driven through the membrane to be directed out of the system or back into the process depending on the application. There are many advantages in tubular membrane configurations. Besides of their rugged construction, they have the distinct advantage of being able to process high suspended solids, and concentrate product successfully and repeatedly to relatively high end point concentration levels without plugging. A common objective of an end-of-pipe waste treatment ultrafiltration system is to reduce waste volume as much as possible to reduce concentrate hauling costs. Tubular membranes are based on either PVDF (polyvinylidene fluoride) or PS (polysulfone). They are capable of continuous, reproducible processing cycles, which means they are cleanable, durable, easy to operate and a proven advance in technology. Tubular Membranes are ideally suited to: Metalworking Oily Waste Wastewater Minimization and Recovery from Industrial Processes Juice Clarification Degreaser Recovery Pulp & Paper Water Treatment and Recovery Paint, Pigment, Dye Recovery and Purification Dialysis Procedures Mining Operations Wastewater Treatment Food Processing Cosmetics Manufacturing Wastewater Treatment Pharmaceuticals Manufacturing Recovery of CIP Solutions plus many other demanding applications requiring large open flow areas with substantially high plugging resistance.

KMS Hollow Fiber Membranes, Spiral Wound Membrane Technology
KMS Hollow Fiber Filtration Technology - Setting New Standards In The Field KMS hollow fiber membranes have been successfully employed in a wide variety of industries including food, juice, pharmaceutical, and metalworking, dairy, wine and most recently municipal drinking water. Depending on the application, hollow fiber membranes can be highly practical and cost effective alternatives to conventional chemical and physical separation processes. Hollow fiber membranes offer the unique benefits of high membrane packing densities, sanitary designs and, due to their structural integrity and construction, can withstand permeate back pressure thus allowing flexibility in system design and operation. The hollow fiber geometry allows a high membrane surface area to be contained in a compact module. This means large volumes can be filtered, while utilizing minimal space, with low power consumption. Hollow fiber membranes can be designed for circulation, dead-end, and single-pass operations. KMS hollow fiber microfiltration and ultrafiltration membranes have become the filtration method of choice for a wide variety of applications. Some of the many hollow fiber membrane filtration applications include: Potable water treatment Juice clarification Citrus juice upgrading Vinegar clarification Wine filtration Dairy processing Oily wastewater minimization Pharmaceutical drug processing Fermentation broth clarification Hollow Fiber Membrane Cartridges KMS hollow fiber cartridges operate from the inside to the outside during filtration. This means that process fluid (retentate) flows through the center of the hollow fiber and permeate passes through the fiber wall to the outside of the membrane fiber. Crossflow can help limit membrane fouling. Other operating techniques that can be employed with hollow fiber membrane systems include back flushing with permeate and retentate reverse flow. Contact KMS and let them help you design your next hollow fiber membrane system. Benefits of Hollow Fiber Membranes (inside to outside permeate flow direction) Affords controlled flow hydraulics Crossflow along the membrane surface limits membrane fouling Open process flow channel which results in less fouling Physical membrane barrier that provides consistent permeate quality Membranes can be backflushed to remove solids from the membrane inside surface, thus extending the time between chemical cleaning cycles High membrane packing density resulting in systems with small footprint Modular system designs can allow for easy future expansion KMS can help you evaluate your specific application requirements and determine if hollow fiber membranes are the best choice for your fluid separation needs. KMS can also enable existing hollow fiber membrane users to enhance the performance and extend the life of their membranes by improving system operating, cleaning and maintenance procedures. KMS also offers submerged hollow fiber membrane modules for MBR treatment of municipal and industrial wastewater. Spiral wound membrane technology Spiral wound membrane technology was first introduced more than 30 years ago when the first FLUID SYSTEMS® RO element was created.

KMS hollow fiber membranes have been successfully employed in a wide variety of industries including food, juice, pharmaceutical, and metalworking, dairy, wine and most recently municipal drinking water. Depending on the application, hollow fiber membranes can be highly practical and cost effective alternatives to conventional chemical and physical separation processes.
Hollow fiber membranes offer the unique benefits of high membrane packing densities, sanitary designs and, due to their structural integrity and construction, can withstand permeate back pressure thus allowing flexibility in system design and operation.
The hollow fiber geometry allows a high membrane surface area to be contained in a compact module. This means large volumes can be filtered, while utilizing minimal space, with low power consumption. Hollow fiber membranes can be designed for circulation, dead-end, and single-pass operations.
KMS hollow fiber microfiltration and ultrafiltration membranes have become the filtration method of choice for a wide variety of applications. Some of the many hollow fiber membrane filtration applications include:
KMS hollow fiber cartridges operate from the inside to the outside during filtration. This means that process fluid (retentate) flows through the center of the hollow fiber and permeate passes through the fiber wall to the outside of the membrane fiber. Crossflow can help limit membrane fouling. Other operating techniques that can be employed with hollow fiber membrane systems include back flushing with permeate and retentate reverse flow. Contact KMS and let them help you design your next hollow fiber membrane system.
