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.
