Commercial Nanofiltration NF Systems NF-300

Pure Aqua’s Commercial Nanofiltration Systems NF-300 Series is a membrane filtration device used most often with low total dissolved solids water such as surface water and fresh groundwater, with the purpose of softening (polyvalent cation removal) and removal of disinfection by-product precursors such as natural organic matter and synthetic organic matter. 

Pure Aqua’s Commercial Nanofiltration Systems NF-300 Series is a membrane filtration device used most often with low total dissolved solids water such as surface water and fresh groundwater, with the purpose of softening (polyvalent cation removal) and removal of disinfection by-product precursors such as natural organic matter and synthetic organic matter. 

Commercial nanofiltration systems are among the best water treatment solutions in the market. Its unique features (listed below) help to provide valuable advantages in various applications, including producing great quality water from untreated water. In addition, these systems have been designed to be highly efficient in water softening applications without the need for added salts or chemicals. 

Nanofiltration systems have emerged as the most preferred choice in commercial applications due to its usage of cutting-edge membrane technology. These newer features incorporated in NF systems have made it far more capable than RO systems in eliminating color from water, in addition to tannins, and turbidity. 

The popularity of NF systems can also be attributable to its low operating pressures during operation, which helps to save power & energy costs. In comparison to reverse osmosis systems, it does not require as much pretreatment since NF systems contain less sensitive membranes, and are more equipped in rejecting bivalent ions such as calcium, magnesium, uranium and radium. Furthermore, Its molecular weight resides between reverse osmosis and ultrafiltration which improves versatility for different industries.

If you’re in need of state-of-the-art commercial nanofiltration systems for applications regarding the production of fresh drinking water, food & beverages water treatment, agriculture, hospitals, restaurants, etc; please call our team to learn more about how our complete line of NF systems can help your commercial business.

Industrial Nanofiltration NF Systems NF-500

Nanofiltration systems offer industrial plants with additional benefits that reverse osmosis fails to provide. Such advantages include the consumption of less water, more efficient in removing hardness (suspended solids) than RO, including foul taste and smell problems.

Nanofiltration systems offer industrial plants with additional benefits that reverse osmosis fails to provide. Such advantages include the consumption of less water, more efficient in removing hardness (suspended solids) than RO, including foul taste and smell problems. 

Industrial nanofiltration systems are designed with advanced nanotechnology for the purposes of improving the capability of removing extremely high TDS levels from water. These NF systems are built-in with elastic features that have fewer maintenance requirements than RO systems and water softeners, including being less prone to fouling.   

Industrial users favor the utilization of nanofiltration systems over RO systems due to its greater capacity in allowing the passage of designed minerals and preventing the passage of unwanted organic compounds. This feature makes nanofiltration ideal in treating water sources that contain high degrees of bivalent ions such as calcium, magnesium, uranium and radium.

NF systems also have earned its reputation as being the most efficient hardness removing membrane technology on the market through targeting and eliminating hardness from water. Just as reverse osmosis systems are efficient in eradicating color, viruses, bacteria, and organic substances, nanofiltration provides the same productivity, along with removing other impurities such as pesticides, and microorganisms. All of these qualities result in the production of high-quality freshwater at a lower cost due to nanofiltration systems using less energy than RO systems. 

Pure Aqua manufactures and distributes a complete category of tailor-made nanofiltration systems, which come equipped with advanced 3D computer modeling and process design software for precise and custom-made solutions.
