What is nano filtration system NF ?
Nano filtration membranes filter water with low total dissolved solids (TDS) to eradicate organic substances and soften water.They are utilized in many water and wastewater treatment industries to effectively remove ions and organic material. Furthermore, they have been adopted as pretreatment to reverse osmosis (RO). Beyond water purification, nanofiltration membranes also find applications in the manufacturing of food and beverages, as well as pharmaceuticals.
Examples of nano filtration system NF Applications:
| Application | Permeate | Concentrate | Benefits of NF |
| Whey / Whey Permeate | Salty wastewater | Desalted whey concentrate | Allows the recovery of lactose and whey protein concentrate with reduced salt content |
| Textile | Dyes | Water, salts, BOD, COD and color | NF is used to desalt dyes resulting in a higher value product |
| Caustic cleaning solutions | Caustic cleaning solution | BOD, COD, suspended solids, caustic cleaner | Allows caustic cleaning solution to be recycled resulting in reduced cleaning chemical costs |
| Recycle of acid solutions | Acid solution | BOD, COD, calcium, suspended solids, acidic water | Allows acid solution to be recycled resulting in reduced cleaning chemical costs |
| Water | Softened water | Hard water | Potable water production. Softened water reduces scaling on equipment and heat exchange surfaces |
| Antibiotics | Salty waste product | Desalted, concentrated Antibiotics | NF produces high value pharmaceutical products |
