Nano Filtration

Nano filtration is an advanced water treatment technology used to remove a range of contaminants from wastewater. It works by forcing wastewater through a membrane that has extremely small pores, allowing only water molecules and certain ions to pass through and rejecting other unwanted substances. This process of filtration is suitable for treating wastewater contaminated with organic matter, bacteria, viruses, heavy metals, organic chemicals and pharmaceuticals. Nano filtration is more effective than traditional methods such as sedimentation and activated carbon filtration because it removes smaller particles from solution.

Nano Filtration is often employed as the final step in a multi-stage wastewater treatment system due to its highly efficient removal of smaller particulates and dissolved substances. In addition to its high removal rate, nano filtration also offers advantages such as low pressure drop across the filtering media and no need for chemical pre or post-treatment. The filtered effluent can be safely discharged into receiving bodies of water or recycled back into production processes in industrial settings.

Nano filtration systems are relatively simple to operate and require minimal maintenance compared to other types of water treatment methods; however they may require expensive membranes that need periodic cleaning or replacement once they become clogged with trapped materials. Additionally, nano-filtration models can contribute significantly to energy costs since they typically require higher operating pressures compared with other treatment technologies. Nonetheless, the cost savings resulting from reduced inorganic pollution makes the investment worthwhile for many applications; the clean effluent produced by nano-filtration means that less chemical usage is required downstream for additional reagent treatment steps processing existing contaminants prior to discharge into waterways.
