Description

NF Series Nanofiltration Membrane Elements:

The NF series nanofiltration membrane elements deliver high permeate flow and outstanding desalination performance, making them ideal for large-scale industrial and municipal water treatment systems.

They feature excellent removal efficiency for pesticides, viruses and bacteria, strong retention of natural organic matter, and moderate rejection of total hardness.

Built with innovative technology, these elements possess a robust membrane surface and superior oxidation resistance. Operation under ultra-low pressure can greatly enhance system efficiency and reduce operational costs.
