The Ultimate FAQ Guide for Nanofiltration Systems.

Nanofiltration was first established late in the 1980s and its popularity since then has grown exponentially. Primarily, this has been driven by the astounding scarcity of freshwater reservoirs in recent years. Nanofiltration systems have massively enhanced efforts geared at reinforcing freshwater supply by effectively treating distinct feed waters. Underneath, we delve into the ins and outs of contemporary Nanofiltration systems and their role in water treatment.

➣What is Nanofiltration?

Nanofiltration is a water treatment process based on the use of membranes and pressure to alienate contaminants from feed water. Compared to ultrafiltration and reverse osmosis, Nanofiltration utilizes membranes with smaller perforations than UF membranes but slightly bigger membrane pores than RO membranes.

Nanofiltration is particularly resourceful in eliminating divalent ions (calcium and magnesium) from raw water hence it is often used to soften hard water. Unlike ion exchange, Nanofiltration does not involve the use of sodium or other salts in water softening /treatment.

➣What is a Nanofiltration System?

Nanofiltration systems are devices meant for water treatment that rely on semi-permeable membranes to alienate soluble ions present in feed water. Technically, Nanofiltration membranes utilize cross-flow filtration as the primary hydraulic profile to treat water. They are mainly used in industrial and commercial applications to treat feed water and improve the quality of tap water.

For diversity in application, Nanofiltration units have varying capacities with commercial NF systems producing up to 32,000 GPD and industrial units producing up to 800,000 GPD. They produce high-grade product water viable for use in varying applications.

➣How Do Nanofiltration Systems Function?

Nanofiltration and reverse osmosis processes have some of their building blocks founded on similar principles. Essentially, the two processes rely on perforated membranes and the application of pressure to alienate dissolved constituents from water. However, Nanofiltration systems get rid of the undesired contaminants without necessitating as much force as reverse osmosis systems.

Generally, Nanofiltration systems eradicate dissolved elements whose molecular weight falls between 200-1000 g mol⁻¹ Typical Nanofiltration membranes have pores measuring approximately 0.001 microns hence numerous dissolved salts, a huge chunk of viruses, and organic constituents are filtered out. Primarily, the Nanofiltration membranes utilized are either:

• Tubular membranes.
• Spiral membranes.

➣What are the Benefits of Using Nanofiltration Systems?

The primary benefit of utilizing Nanofiltration systems is the unlimited supply of high-quality potable water. Unlike ion exchange units, Nanofiltration units eliminate calcium and magnesium ions without necessarily adding salt to the water hence the potable water generated has a low salinity concentration.

Furthermore, Nanofiltration systems operate at a lower pressure compared to reverse osmosis and ultimately consume less energy. Some of the other benefits of using Nanofiltration systems include:

• They exhibit fewer recharge volumes.
• Their salt rejection rate in brackish water is impressive.
• They eliminate heavy metals, nitrates, color, and turbidity.

➣What are the Applications of Nanofiltration Systems?
