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. 

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.

Here at Pure Aqua, Inc., we engineer and build all of our water treatment systems in-house.

Our turn-key water treatment systems are all pre-engineered using the latest CAD technology available.

This enables our teams to build and deliver treatment systems to our customers with quick turnaround times.

Many of our customers require custom engineered systems. These are typically built around similar core systems and thus allowing for improved turnaround times, even for one-off designs.
