8040 Nf Ro Membrane Water Purifier Filter Nanofiltration And Reverse Osmosis 8 Inch

Industrial 8inch NF Water Purifier System RO Membrane for Water Filter Spare Parts

Both reverse osmosis (RO) and nanofiltration (NF) technologies are water treatment methods for water purification equipment. Water purification equipment is generally distinguished by reverse osmosis membranes and nanofiltration membranes made by these two technologies.

The two have the following differences:

1. Different filtering precision Reverse osmosis can remove the smallest solute with a molecular weight of less than 0.0001 microns. Due to its high filtration accuracy, it can filter out bacteria and various impurities in water. It is generally used in the manufacture of household purified water, industrial ultrapure water and medical ultrapure water. Nanofiltration can remove solutes with a molecular weight of about 0.001 microns, and is used in environments with slightly lower filtration accuracy requirements. It is generally used for water softening, micro-pollution desalination and the manufacture of industrial pure water.

2. Different desalination rates The desalination rate of reverse osmosis technology is 99.5%, which can effectively intercept all dissolved salts and various organic substances with a molecular weight greater than 100, while allowing small molecular groups to pass through. The nanofiltration system adopts the method of cross-flow filtration, and the desalination rate is between 80 and 90%. It is mainly used for the concentration and purification of macromolecular substances.

3. The proportion of "wastewater" produced is different Both reverse osmosis and nanofiltration purify water by pressurizing and electrifying, but the reverse osmosis technology due to the different composition of the membrane, the wastewater produced by reverse osmosis is 1:2-1:3, and the wastewater ratio of nanofiltration is 1:1: 1. In terms of water saving and environmental protection, reverse osmosis technology is more resource-intensive. Compared with nanofiltration technology, it has the advantages of partial removal of monovalent ions, low process osmotic pressure, low operating pressure, and energy saving.

1. When PH is above 10, the Maximum Temperature of Continuous Operation is 35ºC.
2. Under certain conditions, the presence of free chlorine and other oxidants in the water may cause serious membrane damage, which doesn't belong to product warranty range.
